Tosedostat is a proprietary orally bioavailable inhibitor of the M1 family of aminopeptidases with potential antineoplastic activity. Tosedostat is converted intracellularly into a poorly membrane-permeable active metabolite (CHR-79888) which inhibits the M1 family of aminopeptidases, particularly puromycin-sensitive aminopeptidase (PuSA), and leukotriene A4 (LTA4) hydrolase; inhibition of these aminopeptidases in tumor cells may result in amino acid deprivation, inhibition of protein synthesis due to a decrease in the intracellular free amino acid pool, an increase in the level of the proapoptotic protein Noxa, and cell death. There are several ongoing Phase 2 cooperative group-sponsored trials and investigator-sponsored trials evaluating the clinical activity of Tosedostat in combination with standard agents in patients with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS).

In Vitro Use Guide

Lymphoma (U-937, HuT 78) and leukemia (HL-60, KG-1, MEG-01, HNT-34, AML-193, KU812, MV-4-11) cells were seeded in 96-well BD-Falcon plates (Becton Dickinson) at a density of 1 to 5 x 10^3 cells per well in the appropriate serum-containing culture medium and cultured at 37C in a humidified 5% (v/v) CO2 incubator for 24 h. Compounds were diluted in the relevant culture medium and added to the wells for a further 72 h. During the final 4 h of this incubation, cells were pulsed with 0.4 mkCi/well of [3H]thymidine (specific activity, 5 mCi/mmol; Amersham Biosciences), harvested onto GF/C glass fiber filter mats (Perkin-Elmer) using a Tomtec harvester, and counted on a 1450 MicroBeta scintillation counter (Perkin-Elmer) to determine the amount of [3H]thymidine incorporated into cellular DNA.
