Description: PPI-2458 is a synthetic derivative of fumagillin with antineoplastic and cytotoxic properties. PPI-2458 irreversibly inhibits the enzyme methionine aminopeptidase type 2 (MetAP2), thereby preventing abnormal cell growth and angiogenesis. PPI-2458 is reported to have a better toxicity profile compared to other agents of its class.

PPI-2458, a novel, orally active agent of the fumagillin class of irreversible methionine aminopeptidase-2 (MetAP-2) inhibitors, potently inhibited the proliferation of B16F10 melanoma cells in vitro, with a growth inhibitory concentration 50% (GI50) of 0.2 nM. B16F10 growth inhibition was correlated with the inhibition of MetAP-2 enzyme, in a dose-dependent fashion, as determined by a pharmacodynamic assay, which measures the amount of uninhibited MetAP-2 following PPI-2458 treatment. The antiproliferative activity, coupled with additional observations from studies in vitro (absence of detectable resistance to PPI-2458 and induction of morphological features consistent with differentiated melanocytes), provides a rationale for assessing the therapeutic potential of PPI-2458 in the treatment of melanoma. see http://www.ncbi.nlm.nih.gov/pubmed/16525646.
