Biricodar dicitrate

    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 100086

CAS#: 174254-13-8 (dicitrate)

Description: Biricodar, also known as VX-710, is a synthetic pipecolinate derivative with potential chemosensitizing activity. Biricodar binds directly to the plasma membrane drug-efflux pumps P-glycoprotein (Pgp) and multidrug resistance protein 1 (MRP-1) and inhibits their activities, which may result in increased intracellular accumulation and retention of cytotoxic agents.
