pathway. We explore structure–activity relationships of the 7-position of harmine for both DYRK1A kinase inhibition and β-cell proliferation based on our related previous structure–activity relationship studies of harmine in the context of diabetes and β-cell specific targeting strategies. 33 harmine analogs of the 7-position substituent were synthesized and evaluated for biological activity. Two novel
最近,我们已经证明,harmine 通过 DYRK1A-NFAT 途径介导体外和体内 β 细胞增殖。我们基于我们之前在糖尿病和 β 细胞特异性靶向策略中对harmine 的相关构效关系研究,探索了harmine 的7 位对DYRK1A 激酶抑制和β 细胞增殖的构效关系。合成了 33 种 7 位取代基的苦胺类似物并评估了其生物活性。确定了两种新型抑制剂,它们显示出 DYRK1A 抑制和人类 β 细胞增殖能力。DYRK1A 抑制剂化合物 1-2b 在高三倍的浓度下诱导的 β 细胞增殖是harmine 的一半。
