Development of tricyclic hydroxy-1H-pyrrolopyridine-trione containing HIV-1 integrase inhibitors
摘要:
New tricyclic HIV-1 integrase (IN) inhibitors were prepared that combined structural features of bicyclic pyrimidinones with recently disclosed 4,5-dihydroxy-1H-isoindole-1,3(2H)-diones. This combination resulted in the introduction of a nitrogen into the aryl ring and the addition of a fused third ring to our previously described inhibitors. The resulting analogues showed low micromolar inhibitory potency in in vitro HIV-1 integrase assays, with good selectivity for strand transfer relative to 3'-processing. Published by Elsevier Ltd.

p-toluenesulfonic acid results in ring opening to give 5-acetoxy-substituted 2-pyridones. The lone pair of electrons on the amide nitrogen assists in opening the oxy bridge to generate a transient N-acyliminium ion, which subsequently loses a proton. In certain cases, the amide electron pair with the oxy bridge is partially twisted from an antiperiplanar arrangement and a competive ring cleavage also occurs to
