Abstract

The invention relates to selective small molecule human constitutive androstane receptor (hCAR) activators of Formula (I) or (II), pharmaceutical compositions thereof, and use thereof for the treatment of hematologic malignancies and other cancers. The small molecule hCAR activator in combination with CPA based chemotherapy regimen provides a synergistic effect to help promote cytoxicity of the cyclophosphamide (CPA) based anticancer treatments including CHOP regimen (CPA, doxorubicin, vincristine, and prednisone) by preferential induction of CYP2B6 over CYP3A4 and promoting the formation of therapeutically active CPA metabolite 4-OH-CPA.
