Design, synthesis and AChE inhibitory activity of indanone and aurone derivatives
摘要:
A new series of indanone and aurone derivatives have been synthesized and tested for in vitro AChE inhibitory activity by modified Ellman method. Most of them exhibit AChE inhibitory activities superior to rivastigmine. Further, the most potent compound 1g was selected to evaluate the effect on the acquisition and memory impairment by mice step-down passive avoidance test. (C) 2008 Elsevier Masson SAS.

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.
