Pyrimidinol carboxylic acids were designed as inhibitors of HIV-1 RNase H function. These molecules can coordinate to two divalent metal ions in the RNase H active site. Inhibition of enzymatic activity was measured in a biochemical assay, but no antiviral effect was observed. Binding wits demonstrated via a solid state structure of the isolated p15-Ec domain of HIV-1 RT showing inhibitor and two Mn(II) ions bound to the RNase H active site.
Design and synthesis of N-methylpyrimidone derivatives as HIV-1 integrase inhibitors
A series of novel beta-diketo derivatives which combined the virtues of dihydroxypyrimidine carboxamide derived from the evolution of DKA and polyhydroxylated aromatics moieties, were designed and synthesized as potential HIV-1 integrase (IN) inhibitors and evaluated their inhibition to the strand transfer process of HIV-1 integrase and anti-HIV-1 activity. The result indicates that 3,4,5-trihydroxylated aromatic derivatives exhibit good inhibition to HIV-1 integrase, but dihydroxylated aromatic derivatives appear little inhibition to HIV-1 integrase. In addition, the preliminary structure-activity relationship (SAR) of these new derivatives was rationalized by docking studies. (c) 2014 Elsevier Ltd. All rights reserved.
