[0065] The term "treatment" as used herein generally refers to obtaining the desired pharmacological and/or physiological effect. The effect may be preventive according to complete or partial prevention of disease or its symptoms; and/or may be therapeutic according to partial or complete stabilization or cure of disease and/or side effects due to the disease. The term "treatment" as used herein encompasses any treatment on a patient's disease, including: (a) preventing the disease or symptom that occurs in a patient who is susceptible to the disease or symptom but not yet diagnosed to suffer from the disease; (b) suppressing symptoms of the disease, i.e., stopping its development; or (c) relieving symptoms of the disease, i.e., causing degeneration of the disease or symptom.

[0066] According to a specific embodiment of the present invention relating to the compound, a stereoisomer thereof, a prodrug thereof, or a pharmaceutically acceptable salt thereof or a pharmaceutically acceptable solvate thereof, the compound is one of the compounds described in the examples below.

[0067] In another aspect, the present invention provides a pharmaceutical composition comprising the compound, a stereoisomer thereof, a prodrug thereof, or a pharmaceutically acceptable salt thereof or pharmaceutically acceptable solvate thereof according to any one of the above embodiments, and a pharmaceutically acceptable carrier, diluent or excipient.

[0068] Methods for preparing a pharmaceutical composition comprising a certain amount of an active ingredient are known or are obvious for a person skilled in the art according to the contents as disclosed in the invention. For example, as described in REMINGTON'S PHARMACEUTICAL SCIENCES, Martin, E.W., ed., Mack Publishing Company, 19th ed. (1995), methods for preparing a pharmaceutical composition comprise incorporating a suitable pharmaceutically acceptable excipient, carrier, diluent amd the like.

[0069] The known methods for preparing a pharmaceutical preparation according to the invention include the conventional mixing, dissolving or freeze-drying methods. The compound according to the invention can be used to prepare into a pharmaceutical composition, which is administered to a patient by various routes suitable for the selected administration mode, for example, oral, or parenteral route (intravenous, intramuscular, topical, or subcutaneous route).

[0070] Therefore, the compound of the invention in combination with a pharmaceutically acceptable carrier (such as an inert diluent or an assimilable edible carrier) can be administered systemically, e.g., orally. They can be encapsulated into a hard or soft shell gelatin capsule, or pressed into a tablet. For the treatment by oral administration, an active compound may be combined with one or more excipients, and be used in a form of a deglutible tablet, a buccal tablet, a troche, a capsule, an elixir, a suspension, a syrup, a wafer and the like The composition and preparation shall comprise at least 0.1% of an active compound. The ratio of the composition to the preparation can be varied certainly, and the composition may account for about 1 wt% to about 99 wt% of a given unit dosage form. In such a therapeutically active composition, the active compound is in an amount sufficient to obtain an effective dosage level.

[0071] A tablet, a troche, a pill, a capsule, and the like may include: a binder, such as tragacanth gum, arabic gum, maize starch or gelatin; an excipient, such as dicalcium phosphate; a disintegrant, such as maize starch, potato starch, and alginic acid etc; a lubricant, such as magnesium stearate; and a sweeting agent, such as sucrose, fructose, lactose or aspartame; or a flavoring agent, such as peppermint, winter green oil or cherry flavor. When the unit dosage form is a capsule, in addition to the above types of materials, it may comprise a liquid carrier, such as vegetable oil or polyethylene glycol. Various other materials may be present as a coating or change the physical form of a solid unit dosage form in other manners. For example, a tablet, a pill or a capsule may be coated with gelatin, wax, shellac or sugar etc. A syrup or elixir may comprise an active compound, sucrose or fructose as a sweeting agent, methyl p-hydroxybenzoate or propyl p-hydroxybenzoate as preservative, a dye and a flavoring agent (such as a cherry flavor or an orange flavor). Certainly, any material for preparing any unit dosage form should be pharmaceutically acceptable and be substantively not toxic in its applied amount. In addition, an active compound may be incorporated into a sustained release preparation and a sustained release device.

[0072] An active compound may also be administered intravenously or intraperitoneally by infusion or injection. An aqueous solution of an active compound or a salt thereof may be prepared, optionally, by mixing it with a non-toxic surfactant. A dispersible formulation in glycerol, liquid polyethylene glycol, glycerin triacetate and a mixture thereof and in oil may also be prepared. Under the common conditions of storage and use, the preparations may comprise a preservative in order to suppress the growth of microbes.

[0073] A pharmaceutical dosage form suitable for injection or infusion may include a sterile aqueous solution or a dispersible formulation or a sterile powder comprising an active ingredient (optionally encapsulated into a liposome) of an immediate preparation such as a solution or a dispersible formulation suitable for sterile injection or infusion. Under all the conditions, the final dosage form shall be sterile, liquid and stable under the production and storage conditions. A liquid carrier may be a solution or a liquid disperse medium, including, for example, water, ethanol, polyols (such as glycerol, propylene glycol, and liquid macrogol, etc), vegetable oil, a non-toxic glyceride and a suitable mixture thereof. A suitable fluidity may be retained, for example, by the formation of liposome, by retaining the desired particle size in the presence of a dispersing agent, or by using a surfactant. The effect of suppressing microbes can be obtained by various antibacterial agents and antifungal agents (such as paraben, chlorbutol, phenol, sorbic acid, and thiomersal, etc). In many conditions, an isotonizing agent, such as sugar, buffer agent or NaCl, is preferably comprised. By the use of a composition of delayed absorbents (e.g., aluminium monostearate and gelatin), an extended absorption of an injectable composition can be obtained.

[0074] A sterile injectable solution can be prepared by mixing a desired amount of an active compound in a suitable solvent with the desired various other ingredients as listed above, and then performing filtration and sterilization. In the case of a sterile powder for the preparation of a sterile injectable solution, the preferred preparation method is vacuum drying and freeze drying techniques, which will result in the production of the powder of the active ingredient and any other desired ingredient present in the previous sterile filtration solution.

[0075] A useful solid carrier includes crushed solid (such as talc, clay, microcrystalline cellulose, silicon dioxide, and aluminum oxide etc). A useful liquid carrier includes water, ethanol or ethylene glycol or water-ethanol/ ethylene glycol mixture, in which the compound of the invention may be dissolved or dispersed in an effective amount, optionally, with the aid of a non-toxic surfactant. An adjuvant (such as a flavor) and an additional antimicrobial agent may be added to optimize the property for a given use.

[0076] A thickener (such as synthetic polymer, fatty acid, fatty acid salt and ester, fatty alcohol, modified cellulose or modified inorganic material) may also be used with a liquid carrier to form a coatable paste, gel, ointment, soap and the like, and be directly applied to the skin of a user.

[0077] A therapeutically effective amount of a compound or an active salt or derivative thereof not only depends on the specific salt selected, but also depends on the administration mode, the nature of the disease to be treated and the age and state of a patient, and finally depends on the decision made by an attending physician or a clinical physician.

[0078] Above preparation may be present in a unit dosage form, which is a physical dispersion unit comprising a unit dose, suitable for administration to a human body and other mammalian body.
