Nucleotide competing reverse transcriptase inhibitors: Discovery of a series of non-basic benzofurano[3,2-d]pyrimidin-2-one derived inhibitors

A HTS screen led to the identification of a benzofurano[3,2-d]pyrimidin-2- one core structure which upon further optimization resulted in 1 as a potent HIV-1 nucleotide competing reverse transcriptase inhibitor (NcRTI). Investigation of the SAR at N-1 allowed significant improvements in potency and when combined with the incorporation of heterocycles at C-8 resulted in potent analogues not requiring a basic amine to achieve antiviral activity. Additional modifications at N-1 resulted in 33 which demonstrated excellent antiviral potency and improved physicochemical properties.
