Definition:An alkaloid that is an enamide obtained by the formal condensation of 3-methylbut-2-enoic acid with 6-(2-amino-1-hydroxyethyl)-4H-pyrido[2,3,4-kl]acridin-4-one. It is isolated from the Okinawan marine tunicate Cystodytes dellechiajei and exhibits cytotoxicity against human epidermoid carcinoma KB cells.
Synonyms:exact_synonym: N-[2-hydroxy-2-(4-oxo-4H-pyrido[2,3,4-kl]acridin-6-yl)ethyl]-3-methylbut-2-enamide
