  Potent and systemically active aminopeptidase N inhibitors designed from active-site investigation

  摘要：

  Derivatives of amino acids bearing various zinc-coordinating moieties (SH, COOH, CONHOH, and PO3H2) were synthesized and tested for their ability to inhibit aminopeptidase N (APN). Among them, beta-amino thiols were found to be the most efficient with IC50's in the 11-50 nM range. These results suggest that the S1 subsite of APN is a deep but not very large hydrophobic pocket, optimally fitting side chains of moderate bulk endowed with some degree of freedom. The iv administration of the inhibitors, alone, did not induce antinociceptive responses on the hot plate test in mice. However, in presence of 10 mg/kg acetorphan, a prodrug of the neutral endopeptidase inhibitor thiorphan, these compounds gave a large increase in the jump latency time with ED50's of 2 and 2.4 mg/kg for the disulfides of methioninethiol [H2NCH(CH2CH2SCH3)CH2S]2 and S-oxomethioninethiol [H2NCH(CH2CH2S(O)CH3)CH2S]2, respectively. These results show that the disulfide forms of beta-amino thiols are efficient prodrugs of aminopeptidase N inhibitors capable of crossing the blood-brain barrier.

  been designed that markedly increase extracellular concentrations and half-lives of enkephalins, inducing potent antinociceptive effects. Several chemical families of Dual ENKephalinase Inhibitors (DENKIs) have previously been developed but devoid of oral activity. We report here the design and synthesis of new pro-drugs, derived from co-drugs combining a NEP and an APN inhibitor through a disulfide

  保护脑啡肽是响应伤害性刺激而释放的内源性阿片肽，是缓解急性和神经性疼痛的一种创新方法。这是通过抑制两个膜结合的锌金属肽酶，中性溶酶（NEP，EC 3.4.24.11）和氨基肽酶N（APN，EC 3.4.11.2）来抑制它们的酶促降解而实现的。已经设计出两种酶的选择性和有效抑制剂，称为脑啡肽酶，它们可以显着增加脑啡肽的细胞外浓度和半衰期，从而诱导有效的抗伤害感受作用。先前已经开发了几种双脑啡肽酶抑制剂（DENKIs）的化学家族，但缺乏口服活性。我们在这里报告新前药的设计和合成，衍生自将NEP和APN抑制剂通过具有侧链的二硫键结合的NEP和APN抑制剂共同改善口服生物利用度。在针对中枢和/或外周阿片样物质系统的各种疼痛动物模型中评估了它们的药理特性。考虑到它在急性和神经性疼痛中的功效，这些新的DENKI之一，选择19 - IIIa进行临床开发。
