hydrazide moiety addresses the acidic Asp 1 residue at the entrance of the S2 pocket by hydrogen bonding while also occupying the flat hydrophobic S1′–S2′ area with its leucine‐isoamylamide moiety. Furthermore, structure–activityrelationshipstudies revealed that functionalization of this distal amino group with alkyl residues can be used to occupy the conserved hydrophobic S2 pocket. In particular, the
组织蛋白酶C是一种具有二肽基氨基肽酶活性的木瓜蛋白酶样半胱氨酸蛋白酶,被认为可以激活各种颗粒相关的丝氨酸蛋白酶。它的肽外切酶活性在结构上由所谓的排斥结构域解释,该结构域阻止S2位点以外的活性位点裂口,并带有Asp 1残基,为肽和蛋白质底物的N端提供锚定点。此处的(2 S,3 S)-反式-环氧琥珀酰-L-亮氨酰胺基-3-甲基丁烷(E-64c)的酰肼(k 2 / K i = 140±5 M -1 s -1)被证明是开发不可逆组织蛋白酶C抑制剂的先导结构。远端氨基的酰肼部分的地址在S2口袋的通过氢键入口处的酸性天冬氨酸1个残基,同时还占据平面疏水S1'-S2'与它的亮氨酸isoamylamide部分区域。此外,结构与活性之间的关系研究表明,带有烷基残基的远端氨基官能团可用于占据保守的疏水S2口袋。特别地,Ñ丁基衍生物被确定为系列中最有效的抑制剂(ķ 2 / ķ我= 56 000±1700 中号-1 小号-1)。

studies, we have shown that this series of inhibitors bind in a noncovalent competitive fashion to the NS3 protease active site. The bound conformation of one of these new azapeptide-based inhibitors was determined using the transfer NOE technique. Incorporation of these new aza-amino acyl functionalities in the P1 position provided a handle to probe for new interactions in the S' region of the enzyme

A divergent strategy for the regioselective and orthogonalsynthesis of complementary regioisomers of N-alkyl-3-substituted-tetrahydroindazolones 3 and 4 was achieved from Boc-protected alkylhydrazines 1. The robustness and substrate generality of this method were validated by synthesizing 3 and 4 through the intra- and intermolecular condensation of 1 with various 2-acylcyclohexane-1,3-diones 2 and

promiscuous responses in mammalian cells by reacting with various proteins, we modified the cinnamamide of our previous hydrazide-based HDACinhibitors (HDACIs) to deactivate the Michael reaction. Representative compound 11h is 2–5 times more potent than lead compound 17 in both HDAC inhibitory activity (IC50 = 0.43–3.01 nM) and cell-based antitumor assay (IC50 = 19.23–61.04 nM). The breakthrough in the pharmacokinetic
