Aminopeptidase

CHR-2797 (Tosedostat) is a novel metalloenzyme inhibitor that exerts antiproliferative effects against a range of tumor cell lines in vitro and in vivo and shows selectivity.

Ubenimex, also known as NK 421 and Bestatin, is a CD13 inhibitor. Ubenimex attenuates acquired sorafenib resistance in renal cell carcinoma by inhibiting Akt signaling in a lipophagy associated mechanism. Ubenimex synergistically enhances the effects of anticancer drugs in hepatocellular carcinoma. Ubenimex inhibits cell proliferation, migration and invasion by inhibiting the expression of APN and inducing autophagic cell death in prostate cancer cells.

Bestatin methyl ester is a cell-permeable derivative of Bestatin which displays slightly stronger inhibition of neutral aminopeptidase than Bestatin, but has much weaker activity against basic aminopeptidase.

Fumagillin is a complex natural product antibiotic which covalently binds a key histidine residue of methionine aminopeptidase type II (MetAP-2), inhibiting endothelial cell proliferation and angiogenesis.

HFI-142 is an insulin-regulated aminopeptidase (IRAP) inhibitor with a Ki of 2.01 μM.
