New amino acids, 3-(6-carboxy-2-oxo-3-pyridyl)-L-alanine, 3-(6-carboxy-2-oxo-4-pyridyl)-L-alanine and N-[2-(3-pyridyl)ethyl]-L-glutamic acid were isolated from the poisonous mushroom and their structures were determined. Their occurrence in this fungus supports the previously proposed biogenesis of acromelic acids.
新氨基酸3-(6-羧基-2-氧代-3-吡啶基)-L-丙氨酸,3-(6-羧基-2-氧代-4-吡啶基)-L-丙氨酸和N- [2-(从有毒蘑菇中分离出3-吡啶基)[乙基] -L-谷氨酸,并确定了其结构。它们在这种真菌中的存在支持了先前提出的丙烯醛酸的生物发生。
