Abstract

La presente invención está encaminada a las cicloalquenocromonas que tienen propiedades antialérgicas. Las cicloalquenocromonas y sus sales no tóxicas, farmacológicamente aceptables, están representadas por la fórmula **fórmula** X es-O-,-S-, o -SO2. Y es de 1 a 4. R1 es hidrógeno o alcohilo, y R2 es H, alcohilo, arilo, carboxilo , alcoxi , aralcoxi, carboxilo o alcoxibarbonilo. Cuando R1 es alcohilo, R2 es hidrógeno, alcohilo o arilo. R3 es carboxilo, alcohiltio, alcohilsulfonilo, alcohilsulfinilo, alcoxicarbonilo o tetrazolilo, siempre que por lo menos uno de los R2 y R3 sea carboxilo, alcoxicarbonilo o tetrazolilo.
