Riterella rubra

Similar metabolites which appear to be derived from tyrosine and brominated tyrosine include botryllamides A-D (31-34), which were isolated from brightly coloured styelid ascidians from the genus Botryllus collected in Fiji and in Australia [32]. Botryllamide D was reported to exhibit marginal cytotoxicity after 72 hour exposure to the human colon cancer cell line HCT 116 (IC50 17 pg/mL), but were inactive in vivo. The rubrolides, which were isolated from Riterella rubra [33] may well be derived from precursors similar to the botryllamides, however, the rubrolides are not alkaloids so have been mentioned here only for comparative purposes.
