  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.

  用于中枢和周围疼痛治疗的新型口服活性双脑啡肽抑制剂（DENKIs）

  摘要：

  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。

  In order to evaluate the possible advantages of potentiating the effects of the endogenous enkephalins, to obtain analgesia without the serious drawbacks of morphine, it was essential to design systemically active compounds which inhibit the two metabolizing enzymes, aminopeptidase N (APN) and neutral endopeptidase 24.11 (NEP). A new concept combining the idea of "prodrug" and "mixed inhibitor" was therefore developed. Given the high efficiency of beta-mercaptoalkylamines as APN inhibitors and of N-(mercaptoacyl) amino acids as NEP inhibitors, compounds associating these molecules through disulfide or thioester bonds, which are known to increase lipophilicity and to favor passage across the blood-brain barrier, have been synthesized. An HPLC study indicated that the disulfide bridge was resistant to serum enzymes but was cleaved by brain membrane homogenates, suggesting that the active inhibitors were released in the central nervous system. The validity of the approach was verified by the efficient antinociceptive responses obtained in the hot plate test in mice after iv administration of disulfide-containing inhibitors (ED50s of from 4 to 26 mg/kg on the jump latency time). The analgesic potencies of the "mixed inhibitor-prodrug" RB 101 [H2NCH(CH2CH2SCH3)CH2SSCH2CH(CH2Ph)CONHCH(CH2Ph)COOCH2Ph] after iv administration were three times greater than those of a similar combined dose of its two constitutive moieties. The separation of the two diastereoisomers constituting RB 101 showed that the analgesia has a stereochemical dependence, the (S,S,S)-isomer being more active than the (S,R,S)-isomer. Furthermore, in the tail flick test in the rat, RB 101 gave 38% analgesia at a dose of 80 mg/kg. Due to its high efficiency and its longer pharmacological effect, RB 101 was selected for a complete study of its analgesic properties.
