Platelet Activating Factor (PAF) antagonists which comprise the compounds of the formula (I): ##STR1## wherein A is an optionally substituted phenyl or an optionally substituted heterocyclic group; X is methylene group, carbonyl group or thiocarbonyl group; R.sup.1, R.sup.2 and R.sup.3 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)拮抗剂包括具有以下结构的化合物(I):其中A是可选择取代的苯基或可选择取代的杂环基团;X是亚甲基、羰基或硫代羰基;R.sup.1、R.sup.2和R.sup.3分别是较低的烷基基团,它们的盐在从肠道吸收方面表现出优异的性能。在化合物(I)的化合物中,其中A是可选择取代的2,3-二氢-1-苯并噁啶-4-基团的化合物是新颖的化合物,并表现出优异的PAF拮抗作用。
