Serendipitous discovery of 2-((phenylsulfonyl)methyl)-thieno[3,2-d]pyrimidine derivatives as novel HIV-1 replication inhibitors

We identified a novel class of 2-((phenylsulfonyl)methyl)-thieno[3,2-d]pyrimidine compounds as potent HIV-1 replication inhibitors serendipitously during the process of evaluation of triazolothienopyrimidine (TTPM) compounds. Herein, we report synthesis and biological evaluation of 2-((phenylsulfonyl)methyl)-thieno[3,2-d]pyrimidine compounds using a cell-based full replication assay to identify thienopyrimidines 6 and 30, which could be further utilized as viable lead compounds.
