As a gene associated with anemia, the erythropoiesis gene is physiologically expressed under hypoxia regulated by †hypoxia-inducing factor-α (HIF-α). Thus, stabilizing HIF-α is a potent strategy to stimulate the expression and secretion of erythropoiesis. In this study, we applied click chemistry to the discovery of HIF prolyl hydroxylase 2 (HIF-PHD2) inhibitors for the first time, and a series of
作为与贫血相关的基因,红细胞生成基因在低氧诱导因子-α(HIF-α)调节的低氧下生理表达。因此,稳定HIF-α是刺激红细胞生成和表达的有效策略。在这项研究中,我们首次将点击化学应用于HIF脯氨酰羟化酶2(HIF-PHD2)抑制剂的发现,并且一系列三唑化合物在荧光偏振测定中显示出更好的抑制活性。特别值得注意的是口服活性HIF-PHD抑制剂15i(IC 50 = 62.23 nM),其活性几乎是III期药物FG-4592(IC 50)的十倍。= 591.4 nM)。此外,它可以将顺铂诱导的贫血小鼠的血红蛋白(120 g / L)上调至正常水平(160 g / L),而在体内未观察到明显的毒性。这些结果证实三唑化合物15i是治疗肾性贫血的有希望的候选者。
