A thienopyrimidie derivative of the formula:
wherein each of R¹ and R² is hydrogen or an optionally-substituted hydrocarbon residue; R³ is hydrogen or a group which is bonded through a carbon atom or nitrogen atom; R⁴ is an optionally-substituted hydrocarbon residue; W is a chemical bond or a connecting group and n is an integer of 1-3, or a salt thereof has potent endothelin antagonist activity, thus being used for treating or preventing acute renal insufficiency, myocardial infarction, liver insufficiency, angina pectoris, cerebral infarction, sub-arachnoid haemorrhage (SAH), hypertension, renal insufficiency, asthma, variant form of angina, Raynaud's syndrome, pulmonary hypertension, surgery shock, chronic cardiac insufficiency, cardiac hypertrophy, arteriosclerosis, migraine and the like, furthermore, for treating or preventing a hypofunction of an organ (e.g. liver, etc.) caused by its surgery or transplant, insufficient microcirculation, still fruthermore, for preventing restenosis after PTCA.
式中的噻吩嘧啶衍生物:
其中 R¹ 和 R² 均为氢或任选取代的烃残基;R³ 为氢或通过碳原子或氮原子键合的基团;R⁴ 为任选取代的烃残基;W 是化学键或连接基团,n 是 1-3 的整数,或其盐具有强效的内皮素拮抗剂活性,因此可用于治疗或预防急性肾功能不全、心肌梗塞、肝功能不全、心绞痛、脑梗塞、蛛网膜下腔出血(SAH)、高血压、肾功能不全、哮喘、变异型心绞痛、雷诺氏综合征、肺动脉高压、手术休克、慢性心功能不全、心脏肥大、动脉硬化、偏头痛等。此外,还可用于治疗或预防因手术或移植导致的器官(如肝脏等)功能减退、微循环不足,以及预防经皮冠状动脉造影术(PTCA)后的再狭窄。
