  Synthesis and Evaluation of a New Class of Nifedipine Analogs with T-Type Calcium Channel Blocking Activity

  摘要：

  我们通过腰果壳中天然化合物腰果酸（anacardic acid）合成了一系列新型化合物，共18种二烷基1,4-二氢-4-(2'-烷氧基-6'-十五烷基苯基)-2,6-二甲基-3,5吡啶二羧酸酯，并研究了它们对瞬时表达在tSA-201细胞上的L型和T型钙通道的阻断作用。该系列化合物的L型钙通道阻断半最大效应浓度（IC50）值范围为1至约40微摩尔，其中增加4-苯环上的烷氧基团和3,5位上的酯取代基可提高亲和力。对系列中最强L型通道阻断剂（PPK-12）的详细分析表明，阻断作用难以逆转，并明显加速了失活过程。此外，在存在PPK-12的情况下，稳态失活曲线的半数失活电压向更超极化的电位偏移20毫伏，导致在更去极化的静息电位下阻断效能增加。令人惊讶的是，PPK-12对T型和L型钙通道的阻断具有相似的亲和力。最弱的L型通道抑制剂之一（PPK-5）对T型通道的亲和力与PPK-12相似，使得PPK-5对T型通道相对于L型通道具有40倍的特异性。因此，二烷基1,4-二氢-4-(2'-烷氧基-6'-十五烷基苯基)-2,6-二甲基-3,5吡啶二羧酸酯可能是作为T型钙通道特异性阻断剂开发的优秀候选物。

  We have synthesized a novel series of 18 dialkyl 1,4-dihydro-4-(2′alkoxy-6′-pentadecylphenyl)-2,6-dimethyl-3,5 pyridine dicarboxylates from anacardic acid, a natural compound found in cashew nut shells, and investigated their blocking action on L- and T-type calcium channels transiently expressed in tSA-201 cells. The IC50 values for L-type calcium channel block obtained with the series ranged from 1 to ∼40 μM, with higher affinities being favored by increasing the size of the alkoxy group on the 4-phenyl ring and ester substituent in the 3,5 positions. A detailed analysis of the strongest L-type channel blocker of the series (PPK-12) revealed that block was poorly reversible and mediated an apparent speeding of the time course of inactivation. Moreover, in the presence of PPK-12, the midpoint of the steady state inactivation curve was shifted by 20 mV toward more hyperpolarized potentials, resulting in an increase in blocking efficacy at more depolarized holding potentials. Surprisingly, PPK-12 blocked T- and L-type calcium channels with similar affinities. One of the weakest L-type channel inhibitors (PPK-5) exhibited a T-type channel affinity that was similar to that seen with PPK-12, resulting in a 40-fold selectivity of PPK-5 for T- over L-type channels. Thus, dialkyl 1,4-dihydro-4-(2′alkoxy-6′-pentadecylphenyl)-2,6-dimethyl-3,5 pyridine dicarboxylates may serve as excellent candidates for the development of T-type calcium-channel specific blockers.
