我们报道了半胱氨酸蛋白酶人组织蛋白酶L(hCatL)的三嗪腈配体的广泛的“杂芳烃扫描”,以研究S3口袋入口处的肽酰胺键Gly67–Gly68上的π堆积。杂芳基·····肽键的堆叠由咪唑并吡啶配体与hCatL的共晶体结构支持。抑制常数(ķ我)受到杂环的多样性和与S3口袋局部环境的特定相互作用的强烈影响。结合亲和力变化三个数量级。与烃类似物相比,所有杂芳族配体均具有增强的结合力。从杂芳烃和肽键的局部偶极矩的方向预测的能量贡献无法得到证实。分子间的C-S⋅⋅⋅O= C相互作用(硫族元素键)与Asn66的主链C = O增强了苯并噻吩基(K i = 4 n m)和苯并噻唑基(K i = 17 n m)配体的结合。 S3口袋。还测试了配体的相关酶罗德沙星。
