assay and western blot analysis, compound 3e demonstrated excellent anti-proliferative activity against solid tumor cells and clear accumulation of ubiquitinated cellular proteins. Furthermore, in the microsomal stability assay compound 3e demonstrated much improved metabolic stability compared to bortezomib, emerging as a promising lead compound for further design of non-peptide proteasome inhibitors
开发了一系列带有1、4-萘醌支架和硼酸战斗部的新型非肽蛋白酶体抑制剂。在对人20S蛋白酶体类胰凝乳蛋白酶样活性的生物学评估中,有5种化合物的IC 50值在纳摩尔范围内。对接实验到酵母20S蛋白酶体中使它们的生物学活性合理化,并允许进一步优化这种有趣的抑制剂类别。在细胞增殖抑制试验和蛋白质印迹分析中,化合物3e对实体瘤细胞表现出出色的抗增殖活性,并清楚地积聚了泛素化细胞蛋白。此外,在微粒体稳定性测定中,化合物3e 证明与硼替佐米相比代谢改善了很多,硼替佐米是一种有望用于进一步设计非肽蛋白酶体抑制剂的先导化合物。
