Background:

M8891 is an orally active, reversible and brain penetrant Methionine Aminopeptidase-2 (MetAP-2) inhibitor with an IC50 of 54 nM and a Ki of 4.33 nM. M8891 does not inhibit MetAP-1 (IC50>10 µM)[1]. M8891 inhibits growth of primary endothelial cells as well as tumor cells and demonstrates antiangiogenic and antitumoral activity[2].

M8891 has an IC50 of 20 nM for HUVEC proliferation[1].

M8891 (po; 20 mg/kg; once a day for 14 days) exhibits strong tumor growth inhibition[1]. M8891 (iv; 0.2 mg/kg) shows low clearance (CL ~0.03-0.4 L/h/kg corresponding to ~1-6% of the liver blood-flow), small to medium volume of distribution (Vss ~0.23-1.3 L/kg), and medium to high oral bioavailability (F ~40-80%)[1].
