Indolonaphthyridine alkaloids (ontology term: CHEMONTID:0003805)

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." [ISBN:978-1-4200-7769-8]
