Significance
(-)-Nangustine, a member of the montanine alkaloid family, is isolated from the bulbs of Narcissus angustifolius subsp. transcarpathicus. It shows selective activity against Trypanosoma brucei rhodesiense, Trypanosoma cruzi and Plasmodium falciparum. Other members of this family also show anxiolytic, antidepressive, anticonvulsive and hypotensive properties. A Pictet-Spengler reaction is used to introduce C6 and to assemble the 5,11-methanomorphanthridin-one framework in (+)-nangustine.
