Cathepsin D (Cath D) has been evidenced as a potential target for cancer therapy. Our previous studies revealed that TB-9, a tasiamide B derivative, exhibited highly potent inhibition against Cath D with satisfactory selectivity over Cath E and BACE1. But this compound was inactive on cell level possibly due to poor membrane permeability. Herein, we report the design, synthesis, and evaluation of two
组织蛋白酶 D (Cath D) 已被证明是癌症治疗的潜在靶点。我们之前的研究表明, tasiamide B 衍生物TB-9对 Cath D 表现出高效的抑制作用,对 Cath E 和 BACE1 具有令人满意的选择性。但这种化合物在细胞水平上没有活性,可能是由于膜通透性差。在此,我们报告了两种新型 Cath D 抑制剂( 2和3 )的设计、合成和评估,该抑制剂将 tasiamide B 支架与特异性靶向内溶酶体区室的细胞穿透肽 (CPP) 相结合。结果表明,2和3不仅保留了对Cath D的高效抑制作用,而且对MDA-MB-231细胞系也有活性。
