PG - 1136-42 AB - Retinoidal activity of retinoic acid isomers [all-trans-retinoic acid (ATRA), 9-cis-retinoic acid (9CRA) and 13-cis-retinoic acid (13CRA)] and their oxidized derivatives [19-hydroxy and 19-oxo derivatives of ATRA (19-hydroxy-ATRA and 19-oxo-ATRA), 19-oxo derivative of 9CRA (19-oxo-9CRA), and 19-hydroxy derivative of 13CRA (19-hydroxy-13CRA)] was evaluated by means of a human promyelocytic leukemia HL-60 cell differentiation induction assay. All the compounds examined showed this activity with ED50 values of 2-30 nM, which are in accordance with their binding activity to nuclear retinoic acid receptors (RARs).
