We proposed a novel compound having an activity of PGI₂ receptor agonist.
A phenoxyacetic acid derivative of the formula
A is -C(R¹ )=N∼OR², -CH(R)NH-OR², -COE, -SO₂E, -CH₂-NR³-Y, -Z-NR³-CONR⁴R⁵, -CH₂-OR⁶, -CO₂R⁶, -CH₂-O∼N=CR⁷R⁸, -CH₂-O-NHCHR⁷R⁸, substituted by imidazolyl(methyl), pyrazolylmethyl, oxazolyl(methyl), thioxazolyl, isoxazolyl, isothiazolyl, oxadiazolyl, triazolylmethyl;
T is alkylene, alkenylene, etc.;
D is -CO₂R¹⁰, -CONR¹¹R¹²;
E is (substitution) amino, hydradino;
Y is substituted (thio) carbonyl, substituted sulfonyl;
Z is -CH=N-, -CH₂NR³-;
R¹, R³, R¹⁰-R¹³ is each H or alkyl, etc. ;
R², R⁴-R⁹ is each H, alkyl or alkyl substituted by phenyl or hetero ring, etc. and non-toxic salts thereof, non-toxic acid addition salts thereof, possess an agonistic on PGI₂ receptor, so it is useful for prevention and/or treatment of thrombosis, arteriosclosis, ischemic heart diseases, gastric ulcer and hypertension.
我们提出了一种具有 PGI₂受体激动剂活性的新型化合物。
一种分子式为
A 是 -C(R¹)=N∼OR²、-CH(R)NH-OR²、-COE、-SO₂-NR³-Y、-Z-NR³-CONR⁴R⁵、-CH₂-OR⁶、-CO₂R⁶、-CH₂-O∼N=CR⁷R⁸、-CH₂-O-NHCHR⁷R⁸,被咪唑基(甲基)、吡唑基甲基、噁唑基(甲基)、硫代噁唑基、异噁唑基、异噻唑基、噁二唑基、三唑基甲基取代;
T 是亚烷基、亚烯基等;
D 是-CO₂R¹⁰、-CONR¹¹R¹²;
E 是(取代)氨基、肼;
Y 是取代的(硫代)羰基、取代的磺酰基;
Z 是-CH=N-、-CH₂NR³-;
R¹、R³、R¹⁰-R¹³ 分别是 H 或烷基等;
R²、R⁴-R⁹分别是 H、烷基或被苯基或杂环取代的烷基等,以及它们的无毒盐、无毒酸加成盐,对 PGI₂受体具有激动作用,因此可用于预防和/或治疗血栓形成、动脉硬化、缺血性心脏病、胃溃疡和高血压。
