A series of aryl sulfonamides of 5,6-disubstituted anthranilic acids were identified as potent inhibitors of methionine aminopeptidase-2 (MetAP2). Small alkyl groups and 3-furyl were tolerated at the 5-position of anthranilic acid, while -OCH3, CH3, and Cl were found optimal for the 6-position. Placement of 2-aminoethoxy group at the 6-position enabled interaction with the second Mn2+ but did not result in enhancement in potency. Introduction of a tertiary amino moiety at the ortho-position of the sulfonyl phenyl ring gave reduced protein binding and improved cellular activity, but led to lower oral bioavailability.
