Novel compound of the formula ##STR1## wherein n is an integer of 1 to 8; R.sub.1 is hydrogen or alkyl of 1-6 carbons; R.sub.2 is hydrogen; R.sub.3 is hydrogen, alkyl of 1-6 carbons, phenyl, benzyl, hydroxy lower alkyl, carbamoyl alkyl, carboxyalkyl, alkoxycarbonylalkyl; R.sub.4 is hydrogen, alkyl of 1-6 carbons, benzyl, or hydroxy lower alkyl; Y is hydrogen, alkyl of 1 to 4 carbon atoms, halo or lower alkoxy; any of its optical isomers, the mixture thereof, or the pharmaceutically acceptable acid addition salt. These compounds are inhibitors of thromboxane synthetase and cyclic AMP phosphodiesterase and are therefore potential cardiovascular agents particularly useful as platelet aggregation inhibitors and anti-thrombotic agents. Accordingly, these compounds will preferably be useful in treating cardiovascular disorders with thrombotic complications. However, they also possess vasodilatory, antisecretory, antihypertensive, inotropic and antimetastatic activities.
化合物的新型式为##STR1##其中n为1到8的整数;R.sub.1为氢或1-6碳的烷基;R.sub.2为氢;R.sub.3为氢、1-6碳的烷基、苯基、苄基、羟基较低烷基、氨基甲基、羧基烷基、烷氧羰基烷基;R.sub.4为氢、1-6碳的烷基、苄基或羟基较低烷基;Y为氢、1-4碳的烷基、卤素或较低烷氧基;其中包括光学异构体、其混合物或药学上可接受的酸加成盐。这些化合物是血栓素合酶和环磷酸腺苷磷酸二酯酶的抑制剂,因此是潜在的心血管药物,特别是作为血小板聚集抑制剂和抗血栓药物。因此,这些化合物将优先用于治疗具有血栓并发症的心血管疾病。但是,它们也具有扩血管、抗分泌、降压、正性肌力和抗转移活性。
