this template. Cathepsin B is unique in its class in that it contains a carboxylate recognition site in the S(2)' pocket of the active site. Inhibitor potency and selectivity were enhanced by tethering a carboxylate functionality from the carbon alpha to the nitrile to interact with this region of the enzyme. This resulted in the identification of compound 10, a 7 nM inhibitor of cathepsin B, with excellent
组织蛋白酶B是半胱氨酸蛋白酶的木瓜蛋白酶超家族的成员,并且已与包括关节炎和癌症在内的多种疾病的病理学有关。为了确定这种蛋白酶的有效可逆抑制剂,我们从先前报道的Cbz-Phe-NH-CH(2)CN(19,IC(50)= 62 microM)开始检查了一系列二肽腈。 。高分辨率X射线晶体学数据和分子模型被用来优化此模板的P(1),P(2)和P(3)取代基。组织蛋白酶B在其类别中是独特的,因为它在活性位点的S(2)'口袋中包含一个羧酸盐识别位点。通过束缚从碳α到腈的羧酸盐官能团来与酶的该区域相互作用,可以提高抑制剂的效力和选择性。
