Development of novel β-carboline-based hydroxamate derivatives as HDAC inhibitors with antiproliferative and antimetastatic activities in human cancer cells
摘要:
A series of novel beta-carboline-based hydroxamate derivatives 12a-k were designed and synthesized, and their biological activities in a series of in vitro assays were evaluated. Several of these beta-carboline derivatives not only showed excellent HDAC1/3/6 inhibitory effects, but also displayed significant antitumor activities against five human cancer cells. The most potent compound 12f demonstrated the highest anticancer potency against cancer cell lines with IC50 values of 0.53-1.56 mu M, which was considerably more potent than harmine (IC50 = 46.7-55.3 mu M) and also three-to ten-fold lower than that of SAHA (IC50=4.48-6.26 mu M). Immunoblot analysis revealed that 12f dose-dependently inhibited histone H3 and a-tubulin acetylation, confirming its HDAC inhibitory effects. Moreover, 12f significantly arrested HepG2 cells at G2/M phase through inhibiting cell cycle related protein CDK1 and cyclin B in a concentration dependent manner. Interestingly, 12f also exerted strong anti-metastasis activity by simultaneously reducing the protein level of MMP2 and MMP9 and inhibiting MAPK signaling pathway. (C) 2017 Elsevier Masson SAS.

The compounds, 3-amino-9H-pyrido[3,4-b]indole and 3-amino-1-methyl-9H-pyrido[3,4-b]indole, which are effectors in induction of sister chromatid exchanges in human cells, were isolated from pyrolysis products of l-tryptophan and characterized by HPLC and UV techniques.
issue that generally occurs in areas with developed animal husbandry. In search of safe and effective therapeutic agents against echinococcosis, we designed and synthesized new 1,3-substituted β-carbolinederivatives based on harmine. Among them, compounds 1a, 1c, and 1e displayed potent inhibitory activity against Echinococcus granulosus in vitro, significantly better than albendazole and harmine. The
