Field of the Invention
[0001] The present invention relates to novel pyrrolopyrimidine and purine derivatives that
are useful in the treatment of abnormal cell growth, such as cancer, in mammals. The
present invention also relates to pharmaceutical compositions containing the compounds
and to the compounds and compositions for use in the treatment of abnormal cell growth
in mammals.
Background
[0002] Lung cancer is the leading cause of cancer death worldwide, with an estimated 1.2
million new cases diagnosed each year. In lung adenocarcinoma, which is the most common
form of lung cancer, patients harboring mutations in the epidermal growth factor receptor
(EGFR) constitute between 10-30 % of the overall population. It is this segment of
patients for whom EGFR inhibitors such as erlotinib or gefitinib can be most effective
(
Paez et al. Science 2004;
Lynch et al. NEJM 2004;
Pao et al, PNAS 2004). The most common mutations associated with good response to these inhibitors are
deletions within exon 19 (e.g. E740-A750) and point mutations in the activation loop
(exon 21, in particular, L858R). Additional somatic mutations identified to date but
to a lesser extent include point mutations: G719S, G719C, G719A, L861 and small insertions
in Exon 20 (
Shigematsu et al JNCI 2005;
Fukuoka et al. JCO 2003;
Kris et al JAMA 2003 and
Shepherd et al NEJM 2004).
[0003] While these agents can be effective treatments for the EGFR mutant subpopulation,
the majority of patients who initially respond develop resistance. The primary mechanism
of resistance, observed in approximately 50 % of patients, is due to a second mutation
(T790M) which occurs at the gatekeeper threonine residue (
Kosaka et al CCR 2006;
Balak et al CCR 2006 and
Engelman et al Science 2007).
[0004] US 2010/144705 A1 describes EGFR inhibitors for the treatment of cancer. Thus, there is a need for
compounds that inhibit EGFR T790M.

of precise dosages. The pharmaceutical composition will include a conventional pharmaceutical
carrier or excipient and a compound described herein as an active ingredient. In addition,
it may include other medicinal or pharmaceutical agents, carriers, adjuvants, etc.
[0404] Exemplary parenteral administration forms include solutions or suspensions of active
compounds in sterile aqueous solutions, for example, aqueous propylene glycol or dextrose
solutions. Such dosage forms can be suitably buffered, if desired.
[0405] Suitable pharmaceutical carriers include inert diluents or fillers, water and various
organic solvents. The pharmaceutical compositions may, if desired, contain additional
ingredients such as flavorings, binders, excipients and the like. Thus for oral administration,
tablets containing various excipients, such as citric acid may be employed together
with various disintegrants such as starch, alginic acid and certain complex silicates
and with binding agents such as sucrose, gelatin and acacia. Additionally, lubricating
agents such as magnesium stearate, sodium lauryl sulfate and talc are often useful
for tableting purposes. Solid compositions of a similar type may also be employed
in soft and hard filled gelatin capsules. Preferred materials, therefor, include lactose
or milk sugar and high molecular weight polyethylene glycols. When aqueous suspensions
or elixirs are desired for oral administration the active compound therein may be
combined with various sweetening or flavoring agents, coloring matters or dyes and,
if desired, emulsifying agents or suspending agents, together with diluents such as
water, ethanol, propylene glycol, glycerin, or combinations thereof.
[0406] The examples and preparations provided below further illustrate and exemplify the
compounds described herein and methods of preparing such compounds. The scope of the
embodiments described herein is not limited in any way by the following examples and
preparations. In the following examples, molecules with a single chiral center, unless
otherwise noted, exist as a racemic mixture. Those molecules with two or more chiral
centers, unless otherwise noted, exist as a racemic mixture of diastereomers. Single
enantiomers/diastereomers may be obtained by methods known to those skilled in the
art.
[0407] In the examples shown, salt forms were occasionally isolated as a consequence of
the mobile phase additives during HPLC based chromatographic purification. In these
cases, salts such as formate, trifluorooacetate and acetate were isolated and tested
without further processing. It will be recognized that one of ordinary skill in the
art will be able to realize the free base form by standard methodology (such as using
ion exchange columns, or performing simple basic extractions using a mild aqueous
base).
[0408] In general, the compounds described herein may be prepared by processes known in
the chemical arts, particularly in light of the description contained herein. Certain
processes for the manufacture of the compounds described herein are provided as further
features of the embodiments and are illustrated in the reaction schemes provided below
and in the experimental section.
[0409] Unless stated otherwise, the variables in Schemes A-J have the same meanings as defined
herein.

[0410] As exemplified in
Scheme A, the core
A-1, which is suitably protected under standard conditions known in the art, such as by
using a SEM protecting group, is subjected to selective chlorine displacement with
an alkoxide, phenoxide or amine (using parent alcohol, phenol or amine derivatives
in the presence of a suitable base {NaH, NaHMDS, KHMDS, K
2CO
3 or DIPEA, respectively}) in a suitable solvent (such as iPrOH, MeCN, THF or DMF)
to afford
A-2. A-2 is then treated under Buchwald amination conditions known in the literature with
an amino-heterocycle to yield
A-3. Nitro reduction under standard conditions known in the art yields aniline
A-4 that is acylated with acryloyl chloride or subjected to amide formation using a suitable
amide coupling agent (such as HATU) and an appropriate carboxylic acid to give
A-5. Subsequent deprotection under standard conditions known in the art affords
A-6. Alternatively, the aniline species
A-4 is globally deprotected first to
A-7 and is then acylated as previously detailed to afford
A-6.

[0411] As exemplified in
Scheme B, the suitably protected core
A-1 is treated with an alkoxide, phenoxide or amine (using parent alcohol, phenol or
amine derivatives in the presence of a suitable base {NaH, NaHMDS, KHDMS, K
2CO
3 or DIPEA, respectively}) in a suitable solvent (such as iPrOH, MeCN, THF or DMF)
to afford the protected intermediate
B-1. Subsequent Buchwald amination under conditions known in the literature with an amino-heterocycle
affords
B-2, which is globally deprotected under standard conditions known in the art to
B-3. Acylation affords
B-4.
[0412] Alternatively, selective deprotection of
B-2 affords the suitably protected intermediate
B-5, which is acylated to
B-6. Subsequent removal of the protecting group yields
B-4.
[0413] Scheme B illustrates a general methodology to afford primary amine derived acrylamides.
It will be understood by one of skill in the art that this methodology may be utilized
to afford secondary amine derived analogues, where a nitrogen atom in ring A serves
as the attachment point of the acrylamide.

[0414] As exemplified in
Scheme C, the suitably protected core
A-1 is treated with a functionalized alkoxide or phenoxide (using parent alcohol or phenol
derivatives in the presence of a suitable base {NaH or K
2CO
3, respectively}) in a suitable solvent (such as DMF) to yield intermediate
C-1. Buchwald amination with a suitable amino-heterocycle yields
C-2, which is followed by deprotection under standard conditions known in the art to afford
C-3.
[0415] Scheme C illustrates a general methodology to afford primary amine derived acrylamides.

to afford secondary amine derived analogues, where a nitrogen atom in ring A serves
as the attachment point of the acrylamide.

[0416] As exemplified in
Scheme D, the suitably protected core
D-1 is subjected to selective chlorine displacement with an alkoxide, phenoxide or amine
(using parent alcohol, phenol or amine derivatives in the presence of a suitable base
{NaH, NaHMDS, KHMDS, K
2CO
3 or DIPEA, respectively}) in a suitable solvent (such as iPrOH, MeCN, THF or DMF)
to afford
D-2. A heteroaromatic coupling reaction (such as a Suzuki reaction with the requisite
heterocyclic boronate or boronic acid) under standard conditions known in the art
yields the coupled product
D-3, which is then treated under Buchwald amination conditions known in the literature
with an amino-heterocycle to yield
D-4. Nitro reduction under standard conditions known in the art yields aniline
D-5, which is acylated with acryloyl chloride to give
D-6. Subsequent deprotection under standard conditions known in the art affords
D-7.

[0417] Electrophiles of the present invention may be synthesized as described in
Scheme E. Amide
E-2 is prepared
via acylation methodology, such as acylating with acyl chlorides in the presence of a
suitable base (such as Hunig's base or triethylamine). Alternatively, amide
E-2 is prepared
via amide coupling with a suitable carboxylic acid under standard conditions known in
the art, such as HATU or DCC in the presence of a suitable base such as triethylamine.
Sulphonamide
E-3 is synthesized by reacting the amine or aniline
E-1 with chloroethanesulphonyl chloride in the presence of a suitable base to afford
the unsaturated sulphonamide
E-3 directly (
see, for example,
Org Lett., 10 (14), 2951-2954, 2008). Reaction of amine or aniline
E-1 with cyanogen bromide in the presence of base affords the cyanamide
E-4 (
see, for example,
J. Med. Chem., 32 (8), 1754, 1989). Coupling of the amine or aniline E-1 with cyanoacetic acid using standard amide
coupling conditions (for example, HATU in the presence of Hunig's base) affords cyanoacetamide
E-5 (
see, for example,
Bioorganic & Medicinal Chemistry Letters, 16(5), 1126-1129, 2006). Haloamide
E-6 can be synthesized by reacting amine or aniline
E-1 with chloroacetyl chloride or fluoroacetyl chloride (
see, for example,
Journal of Medicinal Chemistry, 47(22), 5451-5466; 2004). Alternatively, coupling amine or aniline
E-1 with a suitable carboxylic acid affords haloamide
E-6 (
see Bioorganic & Medicinal Chemistry Letters, 19(22), 6424-6428, 2009). Preparation of the alkyne
E-7 is accomplished by amide coupling of amine or aniline
E-1 with a propargylic acid derivative under standard conditions known in the art (
see, for example,
Tett. Letts, 48(36), 6397-6400, 2007). Lactam
E-9 is synthesized through ring closing metathesis (
see, for example,
Bioorganic & Medicinal Chemistry Letters, 20(6), 1924-1927, 2010) or alternatively, through condensation with 2,5-dihydro-2,5-dimethoxyfuran (see,
for example,
Journal of the Brazilian Chemical Society, 18(4), 855-859, 2007).

[0418] As exemplified in

F-1 is treated with an alkoxide, phenoxide or amine (using parent alcohol, phenol or
amine derivatives in the presence of a suitable base {potassium
tert-pentoxide, NaH, NaHMDS, KHMDS, potassium carbonate or DIPEA}) in a suitable solvent
(such as 1,4-dioxane, iPrOH, THF or DMF) to afford the protected intermediate
F-2. Subsequent Buchwald amination using a preformed palladacycle (see
Biscoe, M.R., et al., J. Am. Chem. Soc., 130:6686 (2008)) with an amino-heterocycle affords the coupled intermediate
F-3, which is deprotected under standard conditions known in the art to
F-4. Acylation affords
F-5.
[0419] Scheme F illustrates a general methodology to afford primary amine derived acrylamides.
It will be understood by one of skill in the art that this methodology may be utilized
to afford secondary amine derived analogues, where a nitrogen atom in ring A serves
as the attachment point of the acrylamide.

amine derivatives in the presence of a suitable base {potassium
tert-pentoxide, NaH, NaHMDS, KHMDS, potassium carbonate or DIPEA}) in a suitable solvent
(such as DMSO, 1,4-dioxane, iPrOH, THF or DMF) to afford the protected intermediate
G-2. Subsequent deprotection under standard conditions known in the art affords the amine
G-3. Acylation affords
G-4.
[0421] Scheme G illustrates a general methodology to afford primary amine derived acrylamides.
It will be understood by one of skill in the art that this methodology may be utilized
to afford secondary amine derived analogues, where a nitrogen atom in ring A serves
as the attachment point of the acrylamide.

[0422] As exemplified in
Scheme H, the core
F-1 is treated with a bis-protected (i.e., a pendant hydroxy group is protected with
a suitable protecting group such as TBS or TBDPS) alkoxide, phenoxide or amine (using
parent alcohol, phenol or amine derivatives in the presence of a suitable base {potassium
tert-pentoxide, NaH, NaHMDS, KHMDS, potassium carbonate or DIPEA}) in a suitable solvent
(such as 1,4-dioxane, iPrOH, THF or DMF) to afford the protected intermediate
H-2. Subsequent Buchwald amination using a preformed palladacycle (see
Biscoe, M.R., et al., J. Am. Chem. Soc., 130:6686 (2008)) with an amino-heterocycle affords the coupled intermediate
H-3, which is deprotected either globally or sequentially under standard conditions known
in the art to
H-4. Acylation afforded

[0423] As exemplified in
Scheme I, the suitably protected core

tert-pentoxide, NaH, NaHMDS, KHMDS, potassium carbonate or DIPEA}) in a suitable solvent
(such as 1,4-dioxane, iPrOH, THF or DMF) to afford the protected intermediate
I-2. Subsequent Buchwald amination under standard conditions known in the art with an
amino-heterocycle affords the coupled intermediate

or amine derivatives, respectively, in the presence of a suitable base {potassium
tert-pentoxide, NaH, NaHMDS, KHMDS, potassium carbonate or DIPEA}) in a suitable solvent
(such as 1,4-dioxane, iPrOH, THF or DMF) to afford the protected intermediate
J-1. Subsequent Suzuki or Negishi aryl coupling conditions known in the art with an appropriate
boronic acid (or ester) or zincate, respectively, affords

affords the coupled intermediate
J-3, which is then globally deprotected under standard conditions known in the art to

H-pyrrolo[2,3-id]pyrimidine (25.0 g, 133 mmol) was suspended in THF (200 mL) using
gentle warming and sonication. This suspension was added dropwise to the base solution

°C for 30 min. SEM-Cl (25 mL, 140 mmol) was added dropwise to the mixture and stirring
was continued at -78 °C for 30 min. Then, the ice bath was allowed to slowly warm
to rt overnight. The reaction was quenched by the addition of cold water (150 mL).
EtOAc (200 mL) was added and the layers separated. The resulting aqueous layer was
then extracted with EtOAc (two x 200 mL). The combined organics were washed with brine

pEGFR Y1068 ELISA Assay
[0742] In order to profile the effect of EGFR T790M inhibitors in cells with different EGFR
mutation status, inhibition of phosphorylation of EGFR at Tyr1068 was determined in
cells with wildtype EGFR or various EGFR mutations - either EGFR single mutant (L858R,
E746-A750 deletion) or EGFR double mutant (L858R+T790M, deletion+T790M). Phosphorylation
of EGFR at Y1068 was measured by PathScan
® Phospho-EGF Receptor (Try1068) Sandwich ELISA kit (# 7240, Cell Signaling Technology
®, Danvers, MA). The PathScan
® Phospho-EGF Receptor (Tyr1068) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked
immunosorbent assay (ELISA) that detects endogenous levels of phospho-EGF Receptor
(Tyr1068) protein. The following cell lines were evaluated in this assay: A549 (EGFR
wildtype, endogenous), NCI-H1975 (EGFR L858R+T790M, endogenous), NCl-H3255 (EGFR L858R,
endogenous), NIH3T3/EGFR_wildtype, NIH3T3/EGFR_L858R, NIH3T3/EGFR_E746-A750_deletion,
NIH3T3/EGFR L858R+T790M, and NIH3T3/EGFR_E746-A750_deletion+T790M. NIH/3T3 parental,
A549, and NCl-H1975 cells were purchased from the American Type Culture Collection
(Manassas, VA). All cells were cultured according to ATCC recommendations. A549 cells
were grown in RPMI media (Invitrogen, Carlsbad) supplemented with 10 % FBS (Sigma,
St Louis, MO), and with 1 % Penn/Strep (Invitrogen). NCl-H1975 cells were grown in
RPMI (Invitrogen) supplemented with 10% FBS (Sigma), and with 1 % Penn/Strep (Invitrogen).
NCI-H3255 cells were grown in RPMI (Invitrogen) supplemented with 10% FBS (Sigma),
and with 1 % Penn/Strep (Invitrogen). NIH/3T3 cells were grown in DMEM (Invitrogen)
supplemented with 10 % newborn calf serum (Invitrogen), and NIH3T3/EGFR mutant cells
were grown in complete media with 5 µg/mL puromycin (Invitrogen). Plasmids (pLPCX)
with various EGFR constructs were made by GenScript (Piscataway, NJ), and stable pools
of NIH/3T3 cells expressing these constructs were made at Pfizer La Jolla. Cells were
plated in complete culture media (50 µL/well) on the bottom of clear tissue culture
treated microtiter plates (#3595, Corning Inc, Corning, NY) and allowed to adhere
overnight at 37°C, 5 % CO
2. Cells were seeded at the following concentrations: (A549: 40,000/well, NCl-H1975:
40,000/well, NCI-H3255: 25,000/well, NIH3T3: 20,000/well). The following day, compound
dilution plates were prepared in 96 well clear V-bottom 0.5 mL polypropylene block
plates (#3956, Corning, Inc). All cell lines were not evaluated for each compound.
Each compound evaluated was prepared as a DMSO stock solution (10 mM). Compounds were
tested in duplicate on each plate, with an 11-point serial dilution curve (1:3 dilution).
Compound treatment (50 µL) was added from the compound dilution plate to the cell
plate. The highest compound concentration was 1 or 10 µM (final), with a 0.3 % final
DMSO (#D-5879, Sigma) concentration. Plates were then incubated for 2 hrs at 37°C,
5 % CO
2. For NIH3T3/wildtype assay, cells were serum starved for 24 hrs prior to compound
treatment; cells were treated in serum-free media as described and then stimulated
for 10 min with EGF (100 ng/mL, Calbiochem/EMD Chemicals, Gibbstown, NJ). For A549/wildtype
assay, cells were plated in full-serum (10 %) media for 24 hrs prior to compound treatment;
cells were treated in full serum media as described and then stimulated for 10 min
with EGF (40 ng/mL/starvation media, Invitrogen). Immediately prior to the end of
the incubation, ice-cold lysis buffer was prepared (1x Cell Lysis Buffer (#9803, Cell
Signaling Technology), 1 mM sodium orthovanadate (Na
3VO
4, #96508, Sigma), 1 mM phenylmethanesulfonyl fluoride (PMSF, 52332, CalBiochem/EMD
Chemicals), complete Mini EDTA-free Protease Inhibitor Cocktail Tablet (1 tablet/10
mL, #11836170001, Roche, Indianapolis, IN), and PhosSTOP Phosphatase Inhibitor Cocktail
Tablet (1 tablet/10 mL, #04906837001, Roche) in pure water. At the end of 2 hrs, media
was flicked off and cells were washed once with ice-cold 1 mM Na
3VO
4 in PBS (100 µL/well, Invitrogen). The wash was then flicked off and ice-cold lysis
buffer was added to the cells (50 µL/well). The plate was shaken for 20-30 min at
4 °C to completely lyse the cells. Sample diluent (50 µL/well) was added to the ELISA
plate, and the lysate (50 µL) was diluted into the sample diluent in each well of
the ELISA plate. Plates were sealed and incubated overnight at 4°C with shaking. The
next day, wells were washed four times with 1x Wash Buffer; plates were taped on lint-free
paper after the final wash prior to adding Add Detection Antibody (green, 100 µL/well)
to each well and incubating for 1 hr at 37°C. After incubation, wells were washed
as described. HRP-Linked secondary antibody (red, 100 µL/well) was added to each well
and incubated for 30 min at 37°C. After incubation, the wells were washed as described.
TMB Substrate (100 µL/well) was added to each well and the plate incubated for 10
minutes at 37°C or 30 minutes at room temperature maximum. Stop Solution (100 µL/well)
was added to each well at the end of the incubation and plates were shaken gently
for a few seconds. Absorbance was read at 450 nm within 30 min after addition of Stop
Solution on a PerkinElmer EnVision Excite Multilabel Reader Method for Absorbance
or on a Molecular Devices SpectraMax
384 Reader for absorbance. Data were analyzed using a four-parameter fit in Microsoft
Excel.
[0743] The results of the
pEGFR Y1068 ELISA assay for the compounds tested are listed in Table 2. The pEGFR ELISA
IC
50 data shown in Table 2 for T790M_L858R and L858R is for 3T3 cell lines, unless otherwise
indicated.

Cell Proliferation Assay
[0744] In order to profile the effect of EGFR T790M inhibitors in various tumorigenic cell
lines, the cell lines tested in the cell proliferation assay exhibit different EGFR
mutation status - either EGFR single mutant (L858R, E746-A750 deletion) or EGFR double
mutant (L858R+T790M, deletion+T790M). Cell proliferation was measured using the CellTiter-Glo®
Luminescent Cell Viability Assay. The assay involves the addition of a single reagent
(CellTiter-Glo® Reagent) directly to cells cultured in serum-supplemented medium.
The assay uses this one-step addition to induce cell lysis and generate a luminescent
signal proportional to the amount of ATP present which is directly proportional to
the number of metabolically active cells present in culture. The following cell lines
were evaluated in this assay: NIH3T3/EGFR_L858R, NIH3T3/EGFR_E746-A750_deletion, NIH3T3/EGFR
L858R+T790M, NIH3T3/EGFR_E746-A750_deletion+T790M, PC-9, PC9-DRH, NCl-H1975, and NCI-H3255.
NIH/3T3 parental cells, NCl-H1975, and NCI-H3255 were purchased from the American
Type Culture Collection (Manassas, VA), and PC-9 cells were obtained from Japan. All
cells were cultured according to recommendations. NIH/3T3 cells were grown in DMEM
(Invitrogen, Carlsbad, CA) supplemented with 10% newborn calf serum (Invitrogen),
and NIH3T3/EGFR mutant cells were grown in complete media with 5 µg/mL puromycin (Invitrogen).
PC-9, NCl-H1975, and NCI-H3255 were grown in RPMI (Invitrogen, Carlsbad, CA) supplemented
with 10% FBS (Sigma, St Louis, MO), and PC9-DRH cells were grown in complete media
with 2 uM PF-00299804. Plasmids (pLPCX) with various EGFR constructs were made by
GenScript (Piscataway, NJ), and stable pools of NIH/3T3 cells expressing these constructs
were made at Pfizer La Jolla. PC9-DRH cells were generated at Pfizer La Jolla by exposing
cells to increasing concentrations of PF-00299804. Cells were plated in complete culture
media (3000 -5000 cells/well, 50 µl/well) on the bottom of white clear-bottom tissue
culture treated microtiter plates (#3610, Corning Inc, Corning, NY) and allowed to
adhere overnight at 37°C, 5% CO
2. The following day, compound dilution plates were prepared in 96 well clear V-bottom
0.5 mL polypropylene block plates (#3956, Corning, Inc). All cell lines were not evaluated
for each compound. Each compound evaluated was prepared as a DMSO stock solution (10
mM). Compounds were tested in duplicate on each plate, with an 11-point serial dilution
curve (1:3 dilution). Compound treatment (50 µl) was added from the compound dilution
plate to the cell plate. The highest compound concentration was 1 or 10 µM (final),
with a 0.3% final DMSO (#D-5879, Sigma, St Louis, MO) concentration. Plates were then
incubated at 37°C, 5% CO
2. After three to five days of compound treatment, CellTiter-Glo® Reagent (#G7573,
Promega, Madison, WI) was prepared in one of two ways. If thawing a frozen aliquot
of CellTiter-Glo® Reagent, the aliquot was thawed and equilibrated to room temperature
prior to use while keeping it protected from light. Alternatively, new bottles of
CellTiter-Glo® Buffer and CellTiter-Glo® Substrate were thawed and equilibrated to
room temperature prior to use. CellTiter-Glo® Buffer (100 mL) was transferred into
the amber bottle containing CellTiter-Glo® Substrate to reconstitute the lyophilized
enzyme/substrate mixture, forming the CellTiter-Glo® Reagent. The reconstituted reagent
was mixed by gently inverting the contents to obtain a homogeneous solution, and went
into solution easily in less than one minute. Any unused reconstituted CellTiter-Glo®
Reagent was immediately aliquoted and frozen at -20°C, protected from light. Cell
plates were equilibrated at room temperature for approximately 30 minutes. An equivolume
amount of CellTiter-Glo® Reagent (100 µL) was added to each well. Plates were mixed
for two minutes on an orbital shaker to induce cell lysis, and then allowed to incubate
at room temperature for 10 minutes to stabilize the luminescent signal. Luminescence
was recorded using the PerkinElmer EnVision Excite Multilabel Reader used for endpoint
reading for Luminescence detection (Waltham, MA). Data were analyzed using a four-parameter
fit in Microsoft Excel.
