Abstract (en)
[origin: ES471696A1] The present invention relates to novel benzopyrane derivatives, especially 3-oxaloamino-4-oxo-4H-1-benzopyrane derivatives of the formula I < IMAGE > (I) in which Ph is substituted or unsubstituted 1,2-phenylene, R is free, esterified or amidated carboxyl and R1 is hydrogen or a substituted or substituted hydrocarbon radical, in the free form or in the form of a salt, exhibit antiallergic activities and are accordingly useful as active ingredients of antiallergic pharmaceutical preparations.
Abstract (de)
