title: New potent P-glycoprotein inhibitors carrying a polycyclic scaffold.
abstract: New pentacyclic inhibitors of the P-glycoprotein carrying nitrogen-containing alkyl chains were synthesized and evaluated for MDR reverting activity on mouse lymphoma cells infected with pHa MDR1/A retrovirus. The activity of the compounds proved to be up to 5-fold higher than verapamil, used as reference compound.
