Tosedostat is a novel and potent oral aminopeptidase inhibitor with clinical activity in a previous phase 1–2 study in elderly patients with relapsed or refractory acute myeloid leukaemia (AML). [2]
Aminopeptidases play a key role in the protein cell cycle. Inhibition of aminopeptidase results in the amino acid deprivation response, which occurs selectively in transformed cells and leads to upregulation of proapoptotic factors including CHOP and NOXA, activation of stress-related pathways such as NFκB, and inhibition of mTOR, which switches off protein synthesis. [2]
Tosedostat (CHR-2797) is converted intracellularly into a pharmacologically active metabolite CHR-79888. [1]
Tosedostat has antiproliferative, antiangiogenic and proapoptotic effects. Tosedostat is currently in a clinical trial phase for anticancer therapy, and displayed a broad antifungal activity against different Candida spp, including Candida glabrata. Tosedostat depletes sensitive tumour cells of amino acids by blocking protein recycling and thereby generates an antiproliferative effect. Tosedostat has activity in older patients with relapsed or refractory AML. [2]
