celastrol derivatives was designed, synthesized, and evaluated for their in vitro cytotoxic activities against six human cancer cell lines (A549, HepG2, HepAD38, PC3, DLD-1 Bax-Bak WT and DKO) and three human normal cells (LO2, BEAS-2B, CCD19Lu). To our knowledge, six derivatives were the first example of dipeptide celastrol derivatives. Among them, compound 3 was the most promising derivative, as it
设计、合成了一系列 11 种 Celastrol 衍生物,并评估了它们对 6 种人类癌细胞系(A549、HepG2、HepAD38、PC3、DLD-1 Bax-Bak WT 和 DKO)和三种人类正常细胞的体外细胞毒活性( LO 2、BEAS-2B、CCD19Lu)。据我们所知,六种衍生物是二肽 celastrol 衍生物的第一个例子。其中,化合物3是最有前景的衍生物,因为它在肝癌HepAD38与人类正常肝细胞LO 2相比表现出显着的抗增殖活性和提高的选择性。化合物6在肝癌细胞中对人正常肺成纤维细胞、CCD19Lu 细胞系显示出更高的选择性。钙还在存在和不存在毒胡萝卜素的情况下评估了3和6 的2+动员,以证明它们对 SERCA 的抑制作用。发现衍生物3和6诱导LO 2、HepG2和HepAD38细胞的细胞凋亡。通过分子对接提出了所有合成的 celastrol 二肽和其他已知抑制剂的潜在对接姿势。最后,在
