BIOLOGICAL ACTIVITY

A pleiotropic biological activities of vitamin A except visual function result from the binding and activating of retinoid nuclear receptors by all-trans-retinoic acid. (Ref. 0067) All-trans-retinoic acid is effective to acute promyelocytic leukemia (APL).(Ref. 0068)Relative physiological activity for All trans-retinyl acetate is 100%.(Ref. 0046)Differentiation-inducing activity,proliferation-inhibitory activity(Ref. 0018)

CHROMATOGRAM DATA

SOURCE

CHEMICAL SYNTHESIS

by oxidation of retinal (Ref. 0019)
Single-step process for all-trans nad 13-cis isomers (Ref. 0020/0021)

METABOLISM

All-trans-retinoic acid is metabolized to 13-cis-RA, 9-cis-RA, retunoyl b-glucuronide, 5,6-epoxyretinoic acid, 4-hydroxyretinoic acid, 4-oxoretinoic acid, and 3,4-didehydroretinoic acid. The 4-oxidization or 4-hydroxylation occurs in liver.(Ref. 0001)
