Title: Lead optimization of methionine aminopeptidase-2 (MetAP2) inhibitors containing sulfonamides of 5,6-disubstituted anthranilic acids. | Journal: Bioorganic & medicinal chemistry letters. 2007 May;17(10):2817-22 | Authors: Wang GT, Mantei RA, Kawai M, Tedrow JS, Barnes DM, Wang J, Zhang Q, Lou P, Garcia LA, Bouska J, Yates M, Park C, Judge RA, Lesniewski R, Sheppard GS, Bell RL. | Abstract: 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 -OCH(3), CH(3), and Cl were found optimal for the 6-position. Placement of 2-aminoethoxy group at the 6-position enabled interaction with the second Mn(2+) 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. | See full PubMed entry: http://www.ncbi.nlm.nih.gov/pubmed/17350258 |
