Description: CHR-2797 is a small molecule aminopeptidase inhibitor that has demonstrated anti-tumour activity in a number of models of cancer, both as a single agent and in synergy with cytotoxic agents such as carboplatin and paclitaxel.

CHR-2797 leads to signs of amino acid deprivation in sensitive cells by targeting intracellular members of the M1/17 family of aminopeptidases, such as puromycin-sensitive aminopeptidase (PuSA), leucine aminopeptidase (LAP), and leukotriene A4 hydrolase (LTA4 hydrolase). Its cytoreductive properties in AML may occur through aminopeptidase N.
