Description
Curator's Comment: Description was created based on several sources, including

Zosuquidar (LY-335979) is an experimental antineoplastic drug. It is is a potent modulator of P-glycoprotein-mediated multi-drug resistance with Ki of 60 nM. Zosuqidar was initially characterized by Syntex Corporation, which was acquired by Roche in 1990. Roche licensed the drug to Eli Lilly in 1997. It was granted orphan drug status by the FDA in 2006 for AML. Zosuquidar Trihydrochloride had been in phase III clinical trials by Kanisa Pharmaceuticals for the treatment of acute myeloid leukaemia. However, this research has been discontinued.

Originator

Curator's Comment: Zosuquidar was originally discovered and identified as an MDR modulator by Syntex Corporation. Syntex was acquired by Roche in 1990. # Syntex Corporation (Roche)

Sample Use Guides

Zosuquidar 550 mg/day by continuous intravenous infusion through a central venous catheter over approximately 6 hours on days 1, 2, and 3.
Route of Administration: Intravenous
In Vitro Use Guide
Zosuquidar (LY-335979) alone shows the cytotoxicity to drug-sensitive and MDR cell lines with IC50 ranging from 6 uM-16 uM and produces its ability to completely reverse the resistance of the oncolytics (vinblastine, doxorubicin, or etoposide) to the MDR cell lines P388/ADR, MCF7/ADR, 2780AD, or UCLA-P3.003VLB at concentration of 0.1 and 0.5 uM
