Celgosivir is a butanoyl ester derivative of castanospermine, a compound derived from the Australian chestnut with activity against hepatitis C virus. Celgosivir rapidly converts to castanospermine in the body, where it is a potent inhibitor of alpha-glucosidase I, a host enzyme required for viral assembly, release, and infectivity.

Sample Use Guides

In Vivo Use Guide

Rats were treated with Castanospermine at a doses of 10, 50, 100, 200 and 500 mg/kg.

Route of Administration: Intraperitoneal

In Vitro Use Guide

LoVo/Dx, W1PR, W1TR and A2780T1 cell lines were used for activity evaluation. The cells were seeded at 4x10^3 cells/well (200 μl) in 96-well culture plates and pre-incubated for 48 h. To examine the effect of BFA, CAS or chemotherapeutic drugs on cell survival, the cells were treated with increasing concentrations of BFA, CAS (Castanospermine, 10 μg/ml for LoVo/Dx, 50 μg/ml for W1PR and W1TR and 60 μg/ml for A2780T1 cells.) for 72 h. Subsequently, 10 μl of MTT labeling reagent was added to the medium (the final concentration of MTT was 0.5 mg/ml) for 4 h and 100 μl of the solubilized solution was then added to each well. After an overnight incubation, the absorbance was measured in a microplate reader at 570 nm with a reference wavelength of 720 nm.
