制备方法与用途

生物活性

PCA50941 是一种 1，4-二氢吡啶衍生物，适用于心血管疾病的研究。

体外研究

PCA50941（1 μM）可使全细胞钙离子 (Ca²⁺) 电流的 I-V 关系向更极化的电位移动约 5-10 mV。该药物还增加了钾（K⁺）诱导的峰值至 655 nM。在 5 mM Ca²⁺ 的存在下，PCA50941 将钙离子 [Ca²⁺] 峰值提高到 427 nM。此外，PCA50941 能够增强由 30 秒的 17.7 mM K⁺ 感应脉冲引起的去甲肾上腺素释放，且这种效应依赖于外钙离子浓度 [Ca²⁺]o。

体内研究

通过冠状动脉内注射 PCA50941（10-120 μM），在山羊中导致较小的冠状血流量 (CBF) 减少。PCA50941（10-300 μM/min）静脉滴注不会改变 CBF 或其他由 i.v. 输液记录的心血管变量。静脉注射 PCA50941（每分钟 100 微克）可在 20 分钟内将 6 只动物中 5 只的血流动力学指标恢复至正常值，从而从休克状态恢复正常。

  Synthesis of 3-[(2,3-dihydro-1,1,3-trioxo-1,2-benzisothiazol-2-yl)alkyl] 1,4-dihydropyridine-3,5-dicarboxylate derivatives as calcium channel modulators

  摘要：

  1,4-Dihydropyridine (DHP) derivatives with a 1,2-benzisothiazol-3-one 1,1-dioxide group, linked through an alkylene bridge to the C-3 carboxylate of the DHP ring, with both vasconstricting and vasorelaxant properties were obtained. In blocking Ca2+-evoked contractions of K+-depolarized rabbit aortic strips, compounds 12 and 41 were 10-fold more potent than nifedipine; 27 other compounds were 1-4-fold more potent. Their vascular versus cardiac selectivity was very pronounced; for instance, the selectivity index for compound 41 was 70-fold higher than that of nifedipine. This was also true for the vasoconstricting compound 22, which was as potent as Bay K 8644 in enhancing the Ca2+-evoked contractions of rabbit aorta strips, yet it had poor inotropic activity in rabbit left atria. Oral adminstration of compounds 38, 40, 43, and 53 (20 mg/kg) caused a 35-37% decrease in systolic blood pressure in spontaneously hypertensive rats (SHR); these effects were similar to those of nifedipine. However, iv administration of these compounds to anesthetized SHR caused a decrease in blood pressure which was more pronounced and long-lasting than that of nifedipine. When administered iv at 100-mu-g/kg, the vasoconstricting compound 22 caused a 40% increase in systolic and diastolic blood pressure. Compound 22 exhibited an unusually interesting feature over the other five Ca2+ DHP agonists: it had diester substitutions at the C-3 and C-5 positions of the DHP ring. Overall, compounds processing these properties might be useful in treating clinical cardiovascular conditions in which DHP Ca2+ antagonists or agonists are indicated.
