Potent, highly selective and orally-bioavailable MMP-13 inhibitors have been identified based upon a (pyridin-4-yl)-2H-tetrazole scaffold. Co-crystal structure analysis revealed that the inhibitors bind at the S1′ active site pocket and are not ligands for the catalytic zinc atom. Compound 29b demonstrated reduction of cartilage degradation biomarker (TIINE) levels associated with cartilage protection
基于(吡啶-4-基)-2 H-四唑支架,已经鉴定出有效,高选择性和口服生物利用度的MMP-13抑制剂。共晶体结构分析表明,抑制剂结合在小号1个′活性位点的口袋,不是催化锌原子的配体。在临床前大鼠骨关节炎模型中,化合物29b证明与软骨保护相关的软骨降解生物标志物(TIINE)水平降低。
