4-Substituted 2-Hydroxyisoquinoline-1,3(2H,4H)-diones as a Novel Class of HIV-1 Integrase Inhibitors
摘要:
A series of 2-hydroxy-1,3-dioxoisoquinoline-4-carboxamides featuring an N-hydroxyimide chelating functionality was evaluated for their inhibitory properties against human immunodeficiency virus type 1 integrase (HIV-1 IN). Several derivatives displayed low nanomolar IC50 values comparable to that of the clinically used raltegravir. A marked effect of one compound on both primary IN-catalyzed reactions, strand transfer (ST), and 3' processing (3'-P), emphasizes a novel IN inhibition mechanism establishing it as a potential new generation IN inhibitor. Substitution of the 2-hydroxyisoquinoline-1,3-dione scaffold at position 4 by carboxamido, chains was beneficial for antiviral activity since reproducible low micromolar anti-HIV activities were obtained for the first time within this scaffold.

A series of 4-methoxycarbonylisoquinoline-1,3-diones was obtained from homophthalic acid in four steps. The key step was the quantitative and rapid alkalinecyclization of 2-methoxycarbonyl-2-(2-methoxycarbonylphenyl) acetamides. Homologation easily afforded in the same conditions 5-carboxy-2-benzazepine-1,3-dione. J. Heterocyclic Chem., 46, 392 (2009).
