its interaction with the 26S proteasome. Despite this advance, 2nd generation inhibitors are needed to improve gankyrin binding and cellular efficacy. To this end, an extensive SAR for the aryl sulfonate ester moiety of the cjoc42 scaffold was explored, and showed that substitutions at the 2-, 3-, and 4-positions manifested significant increases in gankyrin binding, resulting in the most potent binders
gankyrin是一种致癌蛋白,参与各种生物过程,例如细胞生长和增殖。它在某些癌症中的过表达导致gankyrin介导的蛋白质-蛋白质相互作用(PPI)的增加,从而导致癌症扩散。迄今为止,仅鉴定出一个结合gankyrin的小分子(cjoc42),同时抑制了其与26S蛋白酶体的相互作用。尽管取得了这一进步,但仍需要第二代抑制剂来改善gankyrin的结合和细胞功效。为此,对cjoc42支架的芳基磺酸酯部分进行了广泛的SAR研究,结果表明在2、3和4位上的取代表现出gankyrin结合的显着增加,从而导致了最有效的结合剂。 gankyrin至今。
