psoriasis and atherosclerosis. To date, few MSK1 inhibitors were reported. In order to identify new MSK1 inhibitors, a screening of a library of low molecular weight compounds was performed, and the results highlighted the 6-phenylpyridin-2-yl guanidine (compound 1a, IC50~18 µM) as a starting hit for structure-activity relationship study. Derivatives, homologues and rigid mimetics of 1a were designed
丝裂原和应激激活激酶 1 (MSK1) 是一种核激酶,参与促炎转录因子 NF-kB 的激活途径,并在哮喘、银屑病和动脉粥样硬化等炎症性疾病中显示出治疗靶点的潜力。迄今为止,很少报道 MSK1 抑制剂。为了鉴定新的 MSK1 抑制剂,对低分子量化合物库进行了筛选,结果突出显示 6-苯基吡啶-2-基胍(化合物 1a,IC50~18 µM)作为结构的起始命中 -活动关系研究。设计了 1a 的衍生物、同系物和刚性模拟物,并评估了所有合成化合物对 MSK1 的抑制活性。其中,无细胞毒性的 2-氨基苯并咪唑 49d 在显着抑制方面最有效:
