Swainsonine, an indolizidine alkaloid, may act to inhibit the breakdown of glycoprotein by rat liver lysosomes and also suppress MAN2A1 (Golgi mannosidase II). This compound has been reported to be a potent antiproliferative agent via stimulation of lymphocyte proliferation. Additionally, Swainsonine displays the ability to inhibit MAN2B1 (lysosomal alpha-mannosidase) and MAN2C1. Mechanistic studies suggest that this agent can alter carbohydrate processing of beta-galactosidase and beta-glucuronidase.

Rated 5 out of 5 by from ChakrabortyChakraborty, et. al. (PubMed ID 18655794) found that Swainsonine reduced the tyrosinase activity in melanotic hybrid 95-H1 cells by 30 40% when treated with 1 g/ml for 2 days. Increases in migration rate of the tyrosinase protein in SDS-PAGE was also observed post treatment. -SCBT Publication Review
