  Novel Selective Inhibitors of Neutral Endopeptidase for the Treatment of Female Sexual Arousal Disorder. Synthesis and Activity of Functionalized Glutaramides

  摘要：

  Female sexual arousal disorder (FSAD) is a highly prevalent sexual disorder affecting up to 40% of women. We describe herein our efforts to identify a selective neutral endopeptidase (NEP) inhibitor as a potential treatment for FSAD. The rationale for this approach, together with a description of the medicinal chemistry strategy, lead compounds, and SAR investigations are detailed. In particular, the strategy of starting with the clinically precedented selective NEP inhibitor, Candoxatrilat, and targeting low molecular weight and relatively polar mono-carboxylic acids is described. This led ultimately to the prototype development candidate R-13, for which detailed pharmacology and pharmacokinetic parameters are presented.(1)

• Syntheses and Antimicrobial Activities of N-Heterocyclic-β-mercaptocinnamamides and Related Compounds

  In order to obtain useful antimicrobial compounds, a number of N-heterocyclic-β-mercaptocinnamamides (IIIa-i) and related compounds were prepared. N-Heterocyclic phenylpropiolamides (I) were obtained by the reaction of heterocyclic amines with phenylpropioloyl chloride. The addition of thiourea to I gave the isothiuronium salts (II), which were converted into the mercapto compounds (III) with aqueous sodium hydroxide. In the reaction of 2-aminothiazole or 2-amino-4-methylthiazole with phenylpropioloyl chloride in the presence of triethylamine, thiazolo [3, 2-α] pyrimidines (V, VII and VIII) were given together with the expected amides (If and Ig). The hydrolysis of S-[2-(3-methyl-1-phenyl-5-pyrazolyl) carbamoyl-1-phenylvinyl]-isothiourea p-toluenesulfonate (IIe) with aqueous sodium hydroxide at 90° gave 6, 7-dihydro-1, 4-diphenyl-3-methyl-6-oxopyrazolo [3, 4-b] pyridine (IX) and a small amount of the mercapto compound (IIIe). Acyl migration from S to N was found in the acylthio derivatives of N-(2-thiazolyl)-(IIIf) and N-(4-methyl-2-thiazolyl)-β-mercaptocinnamamide (IIIg). Most of the compounds synthesized were considerably active in vitro against various gram-positive bacteria and fungi. However, only three of them were effective against Trichophyton in the in vivo tests.

  为了得到有用的抗菌化合物，制备了一系列 N-杂环-β-巯基肉桂酰胺（IIIa-i）及相关化合物。通过杂环胺与苯基丙炔酰氯的反应，得到了 N-杂环苯基丙炔酰胺（I）。向 I 中加入硫脲得到异硫脲盐（II），再用氢氧化钠水溶液将其转化为巯基化合物（III）。在三乙胺存在下，2-氨基噻唑或 2-氨基-4-甲基噻唑与苯基丙炔酰氯反应，得到了噻唑并[3, 2-α]嘧啶（V、VII 和 VIII）及预期的酰胺（If 和 Ig）。在 90°C 下用氢氧化钠水溶液水解 S-[2-(3-甲基-1-苯基-5-吡唑基)氨基甲酰-1-苯基乙烯基]-硫脲对甲苯磺酸盐（IIe），得到了 6, 7-二氢-1, 4-二苯基-3-甲基-6-氧代吡唑并[3, 4-b]吡啶（IX）及少量巯基化合物（IIIe）。在 N-(2-噻唑基)（IIIf）和 N-(4-甲基-2-噻唑基)-β-巯基肉桂酰胺（IIIg）的酰硫衍生物中，发生了酰基从硫向氮的迁移。所合成的大多数化合物对多种革兰氏阳性细菌和真菌的体外活性相当高。然而，在体内测试中，仅三种化合物对毛癣菌有效。

  expanded set revealed the significance of the third physicochemical parameter, the negative steric effect for long substituents. We also evaluated the larvicidal activity of the synthesized compounds against Spodoptera litura; however, it was not correlated to the binding affinity. The results obtained here suggests that the pharmacokinetic properties must be improved to enhance the larvicidal activity

  咪唑并噻二唑（ITD）是一类有效的具有杀幼虫活性的非甾体蜕皮激素激动剂。以前，我们进行的Hansch-藤田类型ITD类似物定量构效关系（QSAR）分析的（横井等人，Pestic。生物化学生理学。 2015年，120，40-50）。通过咪唑并噻二唑环系统上取代基的疏水性和电负性可以合理地解释其活性。然而，有限的数据点（Ñ = 8）妨碍了其他理化参数的检查。在本研究中，我们扩展了ITD同系物的文库，并使用完整的Sf-9细胞评估了它们的受体结合亲和力。扩展集的QSAR分析揭示了第三个物理化学参数的重要性，即长取代基的负空间效应。我们还评价了合成化合物对斜纹夜蛾的杀幼虫活性; 然而，它与结合亲和力无关。此处获得的结果表明必须改善药代动力学特性以增强ITD的杀幼虫活性。
