as a drug target. Our search for selective inhibitors of LiSIR2RP1 has led, for the first time, to the identification of the antiparasitic and anticancer bisnaphthalimidopropyl (BNIP) alkyl di‐ and triamines (IC50 values in the single‐digit micromolar range for the most potent compounds). Structure–activity studies were conducted with 12 BNIP derivatives that differ in the length of the central alkyl
NAD +依赖性脱乙酰基酶,即沉默调节蛋白,参与多种生物学过程的调控,例如基因沉默,DNA修复,寿命,代谢,细胞凋亡和发育。属于该家族的来自婴儿利什曼原虫的一种寄生虫酶LiSIR2RP1是一种NAD +依赖性微管蛋白脱乙酰基酶和一种ADP-核糖基转移酶。该酶与婴儿乳杆菌的毒力和存活有关,强调了其作为药物靶标的潜力。我们对LiSIR2RP1选择性抑制剂的研究首次导致鉴定抗寄生虫和抗癌的双萘二甲酰亚胺丙基(BNIP)烷基二胺和三胺(IC 50最有效的化合物的单位为微摩尔数的数值)。用12个BNIP衍生物进行了结构活性研究,这些BNIP衍生物的中心烷基链长度不同,它们连接两个萘二甲酰亚胺基丙基部分。最活跃的和选择性的化合物是BNIP diaminononane(BNIPDanon)中,用IC 50的值5.7和97.4μ中号针对酶的寄生虫和人形式(SIRT1)表示。此外,该化合物是一种NAD +竞
