The indolizidine alkaloid swainsonine, a potent inhibitor of Golgi alpha-mannosidase II, has been shown to reduce tumor cell metastasis, enhance cellular immune responses, and reduce solid tumor growth in mice. In our previous Phase I study, swainsonine administered by 5-day continuous infusion
Swainsonine, an alpha-mannosidase inhibitor which blocks Golgi oligosaccharide processing, represents a new class of compounds that inhibit both rate of tumor growth, and metastasis, in murine experimental tumor models. In this first phase I study, the quantitative and qualitative toxicities of
