Recent drug discovery efforts have focused primarily on allosteric inhibition of hFPPS and the discovery of non-bisphosphonate drugs for potentially treating nonskeletal diseases. Hit-to-lead optimization of a new series of thienopyrimidine-based monosphosphonates (ThP-MPs) led to the identification of analogs with nanomolar potency in inhibiting hFPPS. Their interactions with the allosteric pocket of
人法呢基焦磷酸合酶(hFPPS)是甲羟戊酸途径中的关键调节酶,催化C-15异戊二烯类法呢基焦磷酸(FPP)的生物合成。FPP在执行大量细胞功能的小GTP酶的翻译后异戊烯化中起关键作用。尽管hFPPS是溶骨性疾病的公认治疗靶标,但目前可用的双膦酸酯类药物表现出不良的细胞摄取能力,并分布到非骨骼组织中。最近的药物发现工作主要集中在hFPPS的变构抑制和发现潜在用于治疗非骨骼疾病的非双膦酸酯药物上。一系列基于硫代嘧啶的单膦酸酯(ThP-MPs)的先导性优化导致鉴定出具有纳摩尔浓度抑制hFPPS的类似物。它们与酶的变构口袋的相互作用通过晶体学表征,并且结果提供了对变构抑制的药效团要求的进一步见解。
