Efficient synthesis and utilization of phenyl-substituted heteroaromatic carboxylic acids as aryl diketo acid isosteres in the design of novel HIV-1 integrase inhibitors
Three new types of aryl diketo acid (ADK) isosteres were designed by conversion of the biologically labile 1,3-diketo unit into heteroaromatic motif such as isoxazole, isothiazole, or 1H-pyrazole to improve the physicochemical property of ADK-based HIV-1 integrase (IN) inhibitors. The synthesis of the heteroaromatic carboxylic acids was established by employing phenyl beta-diketoester or benzaldehyde as the starting material and 1,3-dipolar cycloaddition as the key reaction. Of the compounds tested, the 3-benzyloxyphenyl-substituted isoxazole carboxylic acid displayed the best IN inhibitory and antiviral activities, with N-hydroxylamidation enhancing the in vitro and in vivo potency. These findings are important for further optimization of ADK-based IN inhibitors. (c) 2008 Elsevier Ltd. All rights reserved.
