Lenthionine is a cyclic organosulfur compound found in shiitake mushrooms and partly responsible for their flavor.^[1] The mechanism of its formation is unclear, but it probably involves the enzyme C-S lyase.

Besides giving flavor to shiitake mushrooms, lenthionine inhibits platelet aggregation, so it is a promising treatment for thrombosis.^[2] Other organosulfur compounds found in garlic have a similar effect.
