An established inhibitor ot dynamin-related protein 1 (Drp1), 3-(2,4-dichloro-5-methoxyphenyl)- 2- thioxoquinazoline-4-one (mdivi-1), was recently reported also to show potent puromycin-sensitive aminopeptidase (PSA)-inhibitory activity. Herein, we report structural development of mdivi-1 derivatives and structure-activity relationship (SAR) analysis of the synthesized compounds, as well as the structurally related PSA-specific inhibitor 3-(2,6-diethylphenyl)quinazoline-2,4-dione (PAQ-22), with the aim of identifying key structural features for inhibitory activity in order to develop selective inhibitors of Drpl, which is a potential target for treatment of Huntington's disease. Among the synthesized compounds, 3-(4-chloro3methoxyphenyl)-2-thioxoquinazoline-4-one 10g) exhibited more potent Drpl-inhibitory activity than mdivi-1 with high selectivity for Drpl over PSA.
