The invention relates to compounds of the formula ##STR1## Y is O or S, *A is paraphenylene or *--(CH.sub.2).sub.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 or aryl, *E is ##STR2## or --(CH.sub.2).sub.k -- wherein k is an integer fro 0 to 4. R.sub.3, R.sub.4 and R.sub.8 are independently hydrogen or lower alkyl, 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 their enantiomers, diastereomers and racemic mixtures thereof, as well as when *E is ##STR3## their geometric isomers and pharmaceutically acceptable acid addition salts thereof. The compounds of formula 1 exhibit activity as paltelet activiating factor (PAF) antagonists and are, therefore, useful in disease states characterized by excess platelet activating factor or for the prevention and treatment of cardiovascular diseases, pulmonary diseases, immunological disorders, inflammatory diseases, dermatological disorders, shock or transplant rejection.
本发明涉及公式##STR1##的化合物。其中,Y是O或S,*A是对苯基或*--(CH.sub.2).sub.n --(X).sub.m --(CH.sub.2).sub.r --,X是O、S或--CH.dbd.CH--,n或r是独立的0到3的整数,s是0到1的整数,m是0到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是独立的氢、低碳基、环烷基、低烯基、Het或芳基,*E是##STR2##或--(CH.sub.2).sub.k --,其中k是0到4的整数。R.sub.3、R.sub.4和R.sub.8是独立的氢或低碳基,R.sub.5和R.sub.6独立地是氢或低碳基,R.sub.7是氢、低碳基、环烷基、Het-低碳基或芳基,Het是单环5-或6-成员的杂环芳香族或含有氮、氧和硫等一到两个杂原子的双环杂芳基基团,该基团可被低碳基、卤素或芳基取代,星号表示连接点,以及它们的对映异构体、顺反异构体和混合物,当*E是##STR3##时,它们的几何异构体和药学上可接受的酸加合盐。公式1的化合物表现出血小板活化因子(PAF)拮抗剂的活性,因此在具有过量血小板活化因子的疾病状态或预防和治疗心血管疾病、肺部疾病、免疫系统疾病、炎症性疾病、皮肤疾病、休克或移植排斥等方面有用。
