Comment: Laniquidar (R101933) is a third generation inhibitor of the ATP-binding cassette transporter P-glycoprotein (P-gp; ABCB1) [1-2]. P-gp is a drug transporter and efflux pump that can promote resistance to drugs, including chemotherapeutics. Pharmacologic inhibition of P-gp is an established strategy that is being investigated to block this resistance mechanism in cancers [1].
