Platelet Activating Factor (PAF) antagonists which comprises the compounds of the formula (I):
wherein A is an optionally substituted phenyl or an optionally substituted heterocyclic group; X is methylene group, carbonyl group or thiocarbonyl group; R¹, R² and R³ are independently a lower alkyl group, and their salts are excellent in absorption from the intestinal canal.
Among the compounds of the formula (I), those wherein A is an optionally substituted 2,3-dihydro-1-benzoxepin-4-yl group are novel compounds and exhibit excellent PAF antagonism.
血小板活化因子(PAF)拮抗剂,包括式(I)化合物:
其中 A 是任选取代的苯基或任选取代的杂环基团;X 是亚甲基、羰基或硫代羰基;R¹、R² 和 R³ 独立地为低级烷基,它们的盐具有良好的肠道吸收性。
在式(I)化合物中,其中 A 为任选取代的 2,3-二氢-1-苯并氧杂卓-4-基团的化合物是新型化合物,具有出色的 PAF 拮抗作用。
