Definition

ChEBI: A thiochromane that is 3,4-dihydro-2H-1-benzothiopyran S,S-dioxide in which the hydrogens at position 4 are both replaced by methyl groups, the hydrogens at position 7 is replaced by a heptyloxy group, w ile the hydrogen at position 6 is replaced by a 1-phenylprop-1-en-2-yl group, the phenyl group of which is substituted at the para position by a carboxy group. It is a selective antagonist for retinoic acid receptor alpha.
