Reproductive and developmental toxicology studies of iminosugar UV-4.

UV-4 (N-(9-methoxynonyl)-1-deoxynojirimycin) is a host-targeted antiviral agent, which targets mammalian proteins (endoplasmic reticulum glucosidases) rather than virally encoded proteins. This mechanism confers both broad-spectrum activity and low potential for generation of viral drug resistance mutations. Reproductive and developmental studies of UV-4 evaluated effects on fertility and early embryonic development in rats, embryo-fetal development in rats and rabbits, and pre- and postnatal development including maternal function in rats.
