The invention relates to compounds of the formula ##STR1## wherein X is --CH.dbd.CH-- or S; R.sub.1 is lower alkyl, lower alkoxy or trifluoromethyl; R.sub.2 is hydrogen, lower alkyl, lower alkoxy, hydroxy or alkanoyloxy; R.sub.3 and R.sub.4, independently, are hydrogen, chlorine, fluorine, lower alkyl or lower alkoxy; s is an integer from 0 to 1, provided that when s is 1, R.sub.2 cannot be hydroxy, lower alkoxy or alkanoyloxy; R.sub.5 is a radical of the formula R.sub.6 --(CH.sub.2).sub.n -- or R.sub.7 --O--(CH.sub.2).sub.m -- wherein R.sub.6 and R.sub.7 are aryl or a heterocyclic radical, n is an integer of from 0 to 2 and m is an integer of from 1 to 2, provided that, when n is 0, R.sub.6 must be attached through a carbon to carbon bond, and provided that R.sub.7 is always attached through a carbon to oxygen bond, and, when at least one asymmetric carbon is present, its enantiomers and racemates, and pharmaceutically acceptable acid addition salts thereof. The compounds of formula I exhibit activity as platelet activating 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X为--CH.dbd.CH--或S;R.sub.1为较低的烷基,较低的烷氧基或三氟甲基;R.sub.2为氢,较低的烷基,较低的烷氧基,羟基或脂肪酰氧基;R.sub.3和R.sub.4分别为氢,氯,氟,较低的烷基或较低的烷氧基;s为0至1的整数,但当s为1时,R.sub.2不能为羟基,较低的烷氧基或脂肪酰氧基;R.sub.5为公式R.sub.6 --(CH.sub.2).sub.n --或R.sub.7 --O--(CH.sub.2).sub.m --的基团,其中R.sub.6和R.sub.7为芳基或杂环基,n为0至2的整数,m为1至2的整数,但当n为0时,R.sub.6必须通过碳与碳键连接,且当至少存在一个不对称碳时,其对映异构体和外消旋体以及药学上可接受的酸加合物盐。公式I的化合物表现出血小板活化因子(PAF)拮抗剂的活性,因此在具有过多血小板活化因子的疾病状态或用于预防和治疗心血管疾病,肺部疾病,免疫障碍,炎症性疾病,皮肤疾病,休克或移植排斥反应等方面有用。
