NCIt definition : An orally-active benzimidazole derivative with potential antineoplastic activity.
As a retinoic acid metabolism blocking agent, liarozole inhibits cytochrome P450-dependent
all-trans-retinoic acid (ATRA)-4-hydroxylase, resulting in an increase in endogenous
ATRA production, inhibition of cell proliferation, and induction of cell differentiation.
This agent also inhibits aromatase, the enzyme that catalyzes the final, rate-limiting
step in estrogen biosynthesis.;
Alternative definition : NCI-GLOSS: An anticancer drug that promotes differentiation by increasing the levels
of retinoic acid within the tumor.;
