against the proliferation of cancer cells and human NAmPRTase. Among them, compound 7 showed similar anti-cancer and enzyme inhibitory activities to compound 1. Further investigation of compound 7 with X-ray analysis revealed a co-crystal structure in complex with human NAmPRTase, suggesting that Asp219 in the active site of the enzyme could contribute to an additional interaction with the pyrrole nitrogen
NAmPRTase(PBEF / Visfatin)在NAD +生物合成的挽救途径中起着关键作用。NAmPRTase一直是通过降低血浆NAD +水平诱导肿瘤细胞凋亡的抗癌剂的有吸引力的靶标。在本报告中,合成了一系列已知的NAmPRTase抑制剂FK866(1)的结构类似物,并测试了其对癌细胞和人NAmPRTase增殖的抑制活性。其中,化合物7显示出与化合物1类似的抗癌和酶抑制活性。化合物7的进一步研究X射线分析显示与人NAmPRTase复合的共晶体结构,这表明该酶活性位点中的Asp219可能有助于与化合物7的吡咯氮进行额外的相互作用。
