Compounds of the formula ##STR1## Y is O ir S, *A is paraphenylene or *----(CH.sub.2)n----(X).sub.m --(CH.sub.2).sub.r ----, X is O, S or --CH.dbd.CH--, n or r, independently, are integers from 0 to 3, s is an integer from 0 to 1, m is an integer from 0 to 1, provided that when m is 1, n+s must be at least 2, R.sub.1 and R.sub.2, independently, are hydrogen, lower alkyl, cycloalkyl, lower alkenyl, Het, aryl, R.sub.3, R.sub.4 and R.sub.8, independently, are hydrogen, lower alkyl, aryl, R.sub.5 and R.sub.6, independently, are hydrogen or lower alkyl, R.sub.7 is hydrogen, lower alkyl, cycloalkyl, Het-lower alkyl or aryl, Het is a monocyclic 5- or 6-membered hetero aromatic or a bicyclic heteroaromatic radical containing one or two hetero atoms selected from nitrogen, oxygen and sulfur, which radical may be substituted by lower alkyl, halogen or aryl, and the asterisk denotes the point of attachment, and when R.sub.6 and R.sub.7 are different, their enantiomers and racemic mixtures thereof, when R.sub.1 and R.sub.2 are different, their geometric isomers, and pharmaceutically acceptable acid addition salts thereof, are described. The compounds of formula I exhibit activity as platelet activating factor (PAF) antagonists and are, therefore, useful in disease states characerized by excess platelet activating factor or for the prevention and treatment of cardiovascular disease, pulmonary diseases, immunological disorders, inflammatory diseases, dermatological disorders, shock or transplant rejection.
式##STR1##的化合物,其中Y为O或S,*A为对苯基或*----(CH.sub.2)n----(X).sub.m--(CH.sub.2).sub.r----,X为O、S或--CH.dbd.CH--,n或r独立地为0至3的整数,s为0至1的整数,m为0至1的整数,但当m为1时,n+s必须至少为2,R.sub.1和R.sub.2独立地为氢、低碳基、环烷基、低烯基、Het、芳基,R.sub.3、R.sub.4和R.sub.8独立地为氢、低碳基、芳基,R.sub.5和R.sub.6独立地为氢或低碳基,R.sub.7为氢、低碳基、环烷基、Het-低碳基或芳基,Het为单环5-或6-成员杂芳基或含有从氮、氧和硫中选择的一个或两个杂原子的双环杂芳基基团,该基团可以被低碳基、卤素或芳基取代,星号表示附着点,当R.sub.6和R.sub.7不同时,它们的对映异构体和混合物,当R.sub.1和R.sub.2不同时,它们的几何异构体,以及其药学上可接受的酸加成盐。式I的化合物表现为血小板活化因子(PAF)拮抗剂的活性,因此在过量血小板活化因子或预防和治疗心血管疾病、肺部疾病、免疫性疾病、炎症性疾病、皮肤病、休克或移植排斥等疾病状态中有用。
