摘要
Retinoic acid, the active metabolite of vitamin A, plays important roles in various physiological and pathological processes. The two-step production of retinoic acid from vitamin A (retinol) is catalyzed by alcohol dehydrogenases and aldehyde dehydrogenases, which are potential therapeutic targets for numerous diseases, such as obesity, diabetes, and cancer. Currently, the lack of a suitable high-throughput cellular assay hinders efforts to identify therapeutic small molecular inhibitors of aldehyde dehydrogenase, such as ALDH1A1. In this report, we utilized high-content imaging technology and a commercially available cell permeable ALDH substrate to develop a 96-well cellular ALDH1A1 assay. This assay has a robust and sensitive readout and is amenable to automation. With this cellular assay, we identified potent selective ALDH1A1 inhibitors to explore the role of retinoic acid production in various preclinical disease models.
