Background:

K-80003 is a potent inhibitor of tRXRα-dependent Akt activation and cancer cell growth.

When MCF-7 cells are cotreated with K-80003, TNFα-induced colocalization of tRXRα with p85α in the cytoplasm is inhibited, resulting in tRXRα nuclear localization. Western blotting shows that K-80003-stabilized tetrameric form of tRXRα is found exclusively in the nuclear fraction, while tRXRα monomer is distributed both in the nuclear and cytoplasmic fractions[2].

K-80003 is a potent inhibitor of AKT activation by all-trans-retinoic acid. K-80003 displays enhanced efficacy in inhibiting tRXRα-dependent AKT activation and tRXRα tumor growth in animals. K-80003 has high affinity to RXRα but lacks COX inhibitory activity[1].
