  Development of Serine Protease Inhibitors Displaying a Multicentered Short (<2.3 Å) Hydrogen Bond Binding Mode:  Inhibitors of Urokinase-Type Plasminogen Activator and Factor Xa

  摘要：

  Novel scaffolds that bind to serine proteases through a unique network of short hydrogen bonds to the catalytic Ser195 have been developed. The resulting potent serine protease inhibitors were designed from lead molecule 2-(2-hydroxyphenyl)1H-benzoimidazole-5-carboxamidine, 6b, which is known to display several modes of binding. For instance, 6b can recruit zinc and bind in a manner similar to that reported by bis(5-amidino-2-benzimidazolyl)methane (BABIM) (Nature 1998, 391, 608-612).(1) Alternatively, 6b can bind in the absence of zinc through a multicentered network of short (<2.3 Angstrom) hydrogen bonds. The lead structure was optimized in the zinc-independent binding mode toward a panel of six human serine proteases to yield optimized inhibitors such as 2-(3-bromo-2-hydroxy-5-methylphenyl)-1H-indole-5-carboxamidine, 22a, and 2-(2-hydroxybiphenyl-3-yl)-1H-indole-5-carboxamidine, 22f. Structure-activity relationships determined that, apart from the amidine function, an indole or benzimidazole and an ortho substituted phenol group were also essential components for optimal potency. The affinities (K-i) of 22a and 22f, for example, bearing these groups ranged from 8 to 600 nM toward a panel of six human serine proteases. High-resolution crystal structures revealed that the binding mode of these molecules in several of the enzymes was identical to that of 6b and involved short (<2.3 Angstrom) hydrogen bonds among the inhibitor hydroxyl oxygen, Ser195, and a water molecule trapped in the oxyanion hole. In summation, novel and potent trypsin-like serine protease inhibitors possessing a unique mode of binding have been discovered.

  The formation of biofilm is one of the important factors for bacteria to develop drug-resistant. A series of halogenated-pyrroles or pyrazoles containing thiazole groups as antibacterial agents were designed and synthesized to target biofilms. Among them, compound showed antibacterial activity against various Gram-positive bacteria, particularly against vancomycin-resistant (MIC ≤0.125 μg/mL). Additionally

  生物膜的形成是细菌产生耐药性的重要因素之一。设计并合成了一系列含有噻唑基团的卤代吡咯或吡唑作为抗菌剂，以针对生物膜。其中，化合物对多种革兰氏阳性菌均表现出抗菌活性，特别是对万古霉素耐药菌（MIC≤0.125 μg/mL）。此外，该化合物在亚 MIC 剂量下可显着抑制生物膜形成。此外，与吡咯霉素 C 相比，该化合物表现出显着较低的哺乳动物细胞毒性，并且还评估了其在不同物种中的肝微粒体代谢稳定性。进一步的感染模型实验证明该化合物是有效的。
