activities of carbonitrile derivatives in the enzymatic activity of cathepsin K and their binding scores predicted using FlexX-Pharm docking program. The binding pattern of [1-(2-cyano-tetrahydro-pyridazine-1-carbonyl)-2-methy-propyl]-carbamic acid benzyl ester (8), one member of this series, was similar to that of the reference. In a bone pit formation assay, compound 8 was shown to dose-dependently
组织蛋白酶K是破骨细胞介导的骨吸收的关键调节剂。在这里,我们发现组织蛋白酶K的酶活性中腈衍生物的抑制活性与使用FlexX-Pharm对接程序预测的结合分数之间的相关性。该系列的一个成员[1-(2-氰基-四氢-哒嗪-1-羰基)-2-甲基-丙基]-氨基甲酸苄酯(8)的结合图案与参考文献相似。在骨坑形成测定中,化合物8显示出剂量依赖性地抑制成熟破骨细胞的骨吸收活性。
