The esters of phenylalkanoic acid of the formula:
wherein R¹ is 4-10 membered, saturated or unsaturated, mono- or bi-cyclic hetero ring containing as hetero atoms:
(i) one or two nitrogen,
(ii) two or three of nitrogen and sulfur in total, or
(iii) one or two sulfur;
R² is hydrogen; or
R¹ and R², taken together with a nitrogen to which they are attached, form 4-7 membered, saturated or unsaturated, mono-cyclic hetero ring containing as hetero atoms:
(i) one or two nitrogen, or
(ii) two or three of nitrogen and oxygen in total,
the aforementioned hetero rings, represented by R¹ or formed by R¹ and R², taken together with a nitrogen to which they are attached, may be substituted by one substituent selected from C1-4 alkyl and C2-5 acyl;
R³ each, independently, is hydrogen or C1-4 alkyl;
R⁴ is hydrogen, halogen, trihalomethyl, C1-4 alkyl, C1-4 alkoxyl C2-5 acyl, cyano, nitro or nitroxy;
R⁵ each, independently, is hydrogen, C1-4 alkyl or phenyl; or the two R⁵'s, taken together with a carbon to which they are attached, form cyclopentane or cyclohexane;
and the pharmaceutically acceptable acid addition salts thereof, have β₁-adrenergic receptor blocking activity, and therefore, are useful for the prevention of and/or in the treatment of cardiovascular diseases such as angina pectoris, myocardial infarction, congestive heart failure, hypertension, arrhythmia, etc.
该公式化合物为苯基烷酸酯,其化学式为:其中R¹为4-10个成员的饱和或不饱和的单环或双环杂环,其杂原子包括:(i)一个或两个氮原子,(ii)两个或三个氮和硫原子的总和,或(iii)一个或两个硫原子;R²为氢;或R¹和R²与它们连接的氮一起形成4-7个成员的饱和或不饱和的单环杂环,其杂原子包括:(i)一个或两个氮原子,或(ii)两个或三个氮和氧原子的总和,前述由R¹代表或由R¹和R²形成的杂环,与它们连接的氮一起,可以被C1-4烷基和C2-5酰基中的一种取代;R³各自独立地为氢或C1-4烷基;R⁴为氢、卤素、三卤甲基、C1-4烷基、C1-4烷氧基、C2-5酰基、氰基、硝基或亚硝基;R⁵各自独立地为氢、C1-4烷基或苯基;或两个R⁵与它们连接的碳一起形成环戊烷或环己烷;以及它们的药学上可接受的酸盐,具有β₁肾上腺素能受体阻滞活性,因此,可用于预防和/或治疗心血管疾病,如心绞痛、心肌梗死、充血性心力衰竭、高血压、心律失常等。
