Cell penetrant, potent and selective nanomolar inhibitor of UDP-glucose ceramide glucosyltransferase (UGCG)
EtDO-P4, a ceramide analog, is a cell penetrant, potent and selective nanomolar inhibitor of UDP-glucose ceramide glucosyltransferase (UGCG). Inhibition of UGCG by EtDO-P4 decreases drug resistance and enhances cytotoxicity of chemotherapeutic drugs such as vincristine, daunorubicin, Lucena-1 and cisplatin.

Multidrug resistance (MDR) in cancer arises from cross-resistance to structurally- and functionally-divergent chemotherapeutic drugs. In particular, MDR is characterized by increased expression and activity of ATP-binding cassette (ABC) superfamily transporters. Sphingolipids are substrates of ABC proteins in cell signaling, membrane
