    • Novel nonpeptide endothelin I antagonists of Formula are described wherein R1 is unsubstituted or substituted cycloalkyl, phenyl, naphthyl or heteroaryl, R2 is unsubstituted or substituted alkyl, aryl or heteroaryl, R3 is unsubstituted or substituted alkyl, cycloalkyl, aryl or heteroayl, and R1 and/or R2 and/or R3 are independently substituted by a total of from 1 to 4 substituents which enhance aqueous solubility with the proviso that when R2 is alkyl and is substituted, the substituent is not oxygen at the &agr;-position of the furanone ring. Further described are methods for the preparation and pharmaceutical compositions of compounds of Formula I, which are useful in treating atherosclerosis, restenosis, Raynaud's phenomenon, mild or severe congestive heart failure, cerebral ischemia, cerebral infarction, embolic stroke, cerebral vasospasm, glaucoma, subarachnoid hemorrhage, hemorrhagic stroke, diabetes, gastric ulceration and mucosal damage, ischemic bowel disease, Chrohn's disease, male penile erectile dysfunction, essential or malignant hypertension, pulmonary hypertension, pulmonary hypertension after bypass, cancer, especially malignant hemangioendothelioma or prostate cancer, myocardial infarction or ischemia, acute or chronic renal failure, renal ischemia, radiocontrast-induced nephrotoxcity, endotoxic, septic hemorrhagic shock, angina, preeclampsia, asthma, arrhythmias, benign prostatic hyperplasia, and elevated levels of endothelin.
    • 苯基,萘基或杂芳基,R2为未取代或取代的烷基,芳基或杂芳基,R3为未取代或取代的烷基,环烷基,芳基或杂芳基,R1和/ 或R 2和/或R 3独立地被总共1至4个增强水溶性的取代基取代,条件是当R 2是烷基且被取代时,该取代基不是在呋喃酮环的α-位上的氧。 进一步描述了用于制备治疗动脉粥样硬化,再狭窄,雷诺现象,轻度或重度充血性心力衰竭,脑缺血,脑梗死,栓塞性中风,脑血管痉挛,青光眼,蛛网膜下腔出血 出血性,出血性中风,糖尿病,胃溃疡和粘膜损伤,缺血性肠病,克罗恩病,男性阴茎勃起功能障碍,基本或恶性高血压,肺动脉高压,旁路后肺动脉高压,癌症,特别是恶性血管内皮瘤或前列腺癌,心肌梗塞或 缺血,急性或慢性肾衰竭,肾缺血,放射性对照诱导的肾毒性,内毒素性,败血性出血性休克,心绞痛,先兆子痫,哮喘,心律失常,良性前列腺增生和内皮素水平升高。
