Identification of selective and reversible LSD1 inhibitors with anti-metastasis activity by high-throughput docking.

The overexpression of lysine specific demethylase 1 (LSD1) has been reported in various human tumors. There is increasing interest in targeting LSD1 with small molecules for cancer treatment. A released structure of an LSD1 kinase domain in complex with FAD was used to set up a low-cost high-throughput docking protocol for quick identification of LSD1 inhibitors. The most promising hit L05 was confirmed to be a potent, selective and reversible LSD1 inhibitor and displayed marked inhibition of colorectal cells migration without significant cytotoxicity.
