Synthesis and in Vitro Anticancer Activity of the First Class of Dual Inhibitors of REV-ERBβ and Autophagy
摘要:
Autophagy inhibition is emerging as a promising anticancer strategy. We recently reported that the circadian nuclear receptor REV-ERB beta plays an unexpected role in sustaining cancer cell survival when the autophagy flux is compromised. We also identified 4-[[[1-(2-fluorophenyl)cyclopentynamino]methyl]-2-[(4-methylpiperazin-1-yl)methyl]phenol, 1 (ARN5187), as a novel dual inhibitor of REV-ERB beta and autophagy. 1 had improved cytotoxicity against BT-474 breast cancer cells compared to chloroquine, a clinically relevant autophagy inhibitor. Here, we present the results of structure activity studies, based around 1, that disclose the first class of dual inhibitors of REV-ERB beta and autophagy. This study led to identification of 18 and 28, which were more effective REV-ERB beta antagonists than 1 and were more cytotoxic to BT-474. The combination of optimal chemical and structural moieties of these analogs generated 30, which elicited 15-fold greater REV-ERB beta inhibitory and cytotoxic activities compared to 1. Furthermore, 30 induced death in a panel of tumor cell lines at doses 5-50 times lower than an equitoxic amount of chloroquine but did not affect the viability of normal mammary epithelial cells.

Methods have been developed for the synthesis of new 1H-benzotriazol-1-ylmethyl- and 1H-imidazol-1-ylmethyl-substituted chalcones starting from 2-hydroxyacetophenone. The procedures include chloromethylation, N-alkylation, and Claisen-Schmidt condensation. The presence of an imidazole fragment on the ring A and piperazine fragment on the ring B of the resulting chalcones increases their antimicrobial activity (minimum inhibitory concentration 12.5-50.0 mu g/mL), whereas introduction of a benzotriazole fragment reduces the antimicrobial activity.
