Lactarius necator

The only natural product based on this ring system is necatorone 193. This alkaloid was isolated from a toadstool, Lactarius necator (84TL3575). This fungal metabolite showed a considerable mutagenic activity in the Ames test. A synthesis of necatorone 193 involving oxidative cyclization has been reported (Scheme 33) (85TL5975). [Pg.123]

The biogenesis of necatorone and related Lactarius alkaloids is not yet fully understood. However, in a preliminary feeding experiment, a high incorporation of tyrosine-i- C into necatorone was found when the precursor was administered to a young specimen of Lactarius necator. These... [Pg.271]
