Chemical Taxonomy
Description belongs to the class of organic compounds known as indolonaphthyridine alkaloids. These are a numerous and relatively straightforward subgroup of the b-carbolines, e.g. Canthin-6-one, in which an additional C3 unit is attached between C-1 and the indole nitrogen to form an additional ring. The group includes a few dimeric examples, such as Haplophytine.
