LE 135 is a retinoic acid antagonist; displays moderate selectivity for RARβ over RARα (Ki values are 0.22 and 1.4 μM respectively). Highly selective over RARγ and RXRα. Inhibits human HL-60 leukemia cell differentiation induced by Am80 (IC50 = 150 nM).
LE 135 is also offered as part of the Tocriscreen 2.0 Max. Find out more about compound libraries available from Tocris.
