A compound having pharmaceutical activity, of the formula
in which
A is hydrogen or -(CR¹R²) R³ where x is 0 or 1 to 4, R¹ and R² are each hydrogen or C₁₋₄ alkyl and R³ is -CN, -COOH, tetrazolyl or -CONHSO₂R⁴ where R⁴ is optionally substituted phenyl, and
is selected from
where R⁵ and R⁶ are each hydrogen, C₁₋₄ alkyl or -(CR¹R²)xR³ where x, R¹ , R² and R³ are as defined above, and R⁷ is hydrogen, C₁₋₄ alkyl or -(CR¹ R²)xR³ where x is 1 to 4, and R¹, R² and R³ are as defined above;
provided that when A is hydrogen at least one of R⁵, R⁶ and R⁷ is -(CR¹R²)xR³, and provided that when
is
A is -(CR¹R²)xR³ and x is 1 to 4 then R³ is -CONHSO₂R⁴; and salts and esters thereof.
一种具有药物活性的化合物,其化学式为
其中
A 是氢或-(CR¹R²) R³ 其中 x 是 0 或 1 至 4,R¹ 和 R² 分别是氢或 C₁₋₄ 烷基,R³ 是-CN、-COOH、四唑基或-CONHSO₂R⁴,其中 R⁴ 是任选取代的苯基,以及
选自
其中 R⁵ 和 R⁶ 各为氢、C₁₋₄ 烷基或-(CR¹R²)xR³,其中 x、R¹、R² 和 R³ 如上文所定义,且 R⁷ 为氢、C₁₋₄ 烷基或-(CR¹R²)xR³,其中 x 为 1 至 4,且 R¹、R² 和 R³ 如上文所定义;
条件是当 A 为氢时,R⁵、R⁶ 和 R⁷ 中至少有一个是-(CR¹R²)xR³,并且当
是
A 为-(CR¹R²)xR³且 x 为 1 至 4 时,则 R³ 为-CONHSO₂R⁴;以及它们的盐和酯。
