Biochem/physiol Actions

LE135 is a retinoic acid receptor (RAR) antagonist with selectivity for RARβ (Ki = 220 nM) over RARα (Ki = 1.4 μM). LE135 inhibits retinoic acid-induced transcriptional activation of RARβ (>70% inhibition at 10 μM), but not RARα, RARγ or retinoid X receptor α (RXRα). There is high interest in retinoic acid receptors for cancer and for differentiation studies. LE135 has been shown to inhibit retinoid Am80-induced differentiation of human promyelocytic leukemia HL-60 cells with an IC₅₀ value of 0.2 μM. LE135 has been used to study the role of a retinoic acid receptor-β (RARβ) on the differentiation of mesenchymal stem cells, and was found to inhibit the neuronal differentiation promoting effects of all-trans retinoic acid (ATRA) on mesenchymal stem cells.
