Figure 1From: 4-(N,N-dipropylamino)benzaldehyde inhibits the oxidation of all-trans retinal to all-trans retinoic acid by ALDH1A1, but not the differentiation of HL-60 promyelocytic leukemia cells exposed to all-trans retinalChemical structures for ALDH1A1 substrate and inhibitor. (A) substrate: all-trans retinal. (B) inhibitor: 4-(N,N-dipropylamino)benzaldehyde (DPAB).Back to article page
