Definition:A didemnin that is didemin B in which the hydroxy group of the 1-(2-hydroxypropanoyl)-L-prolinamide moiety has been oxidised to the corresponding ketone. It was originally isolated from the Mediterranean tunicate Aplidium albicans.
Synonyms:exact_synonym: 1-(2-oxopropanoyl)-L-prolyl-N-[(3S,6R,7S,10R,11S,15S,17S,20S,25aS)-10-[(2S)-butan-2-yl]-11-hydroxy-3-(4-methoxybenzyl)-2,6,17-trimethyl-20-(2-methylpropyl)-1,4,8,13,16,18,21-heptaoxo-15-(propan-2-yl)docosahydro-15H-pyrrolo[2,1-f][1,15,4,7,10,20]dioxatetraazacyclotricosin-7-yl]-N(2)-methyl-D-leucinamide
