zoledronate in pancreatic cancer cell lines, as well as an HsFPPS-dependent mechanism of action. Hit-to-lead optimization of CA improved HsFPPS inhibition by >100-fold. A slow dissociation inhibition pattern and a noncompetitive allosteric binding mode were found, and cellular mechanism-of-action studies showed that these inhibitors inhibit tumor cell growth primarily by inhibiting HsFPPS, leading
人法呢基焦磷酸合酶(智人FPPS,Hs FPPS)是治疗骨吸收疾病和某些癌症的靶标。Hs FPPS被双膦酸盐有效地抑制,但是由于不良的细胞渗透和在软组织中的分布,目前人们对开发非双膦酸盐抑制剂作为癌症治疗剂感兴趣。在这里,我们报告了基于酚二萜烯肌酸(CA)的Hs FPPS抑制剂的发现和开发,该酚是迷迭香和鼠尾草中发现的一种抗菌药物,在胰腺癌细胞系中也显示出比双膦酸盐类药物唑来膦酸盐更好的细胞抗癌活性。作为HSFPPS依赖的作用机制。CA的按部就班优化将Hs FPPS抑制作用提高了100倍以上。发现慢解离抑制模式和非竞争性变构结合模式,并且细胞作用机理研究表明,这些抑制剂主要通过抑制Hs FPPS抑制肿瘤细胞生长,从而导致Ras异戊二烯化和细胞凋亡的下调。在胰腺癌细胞中发现该系列化合物以及机理证明,可能为使用天然产物抑制剂在软组织癌中靶向Hs FPPS铺平道路。
