A new strategy for the facile synthesis of hydroxyalkylamides through the ring-opening reaction of lactone with amine promoted by dibutyltin acetate was developed. A series of hydroxyalkylamide compounds were obtained and the method was successfully applied to the synthesis of pharmaceutically active molecules tyrosinase inhibitor V and HDAC inhibitor VI via a three-step synthetic pathway. The broad

Lysine specific demethylase 1 (LSD1) plays a key role in the regulation of gene expression by removing the methyl groups from methylated Lys4 of histone H3 (H3K4). Here we report the identification of the first small-molecule LSD1-selective inhibitors. These inhibitors show in vivo H3K4-methylating activity and antiproliferative activity and should be useful as lead structures for anticancer drugs and as tools for studying the biological roles of LSD1.
