These are organic compounds containing the benzazocine ring system, which consists of a benzene ring bound to an azocine ring. 5,6',12-trihydroxy-6,7'-dimethoxy-7,21,30-trimethyl-27-oxo-3',4'-dihydro-2'H-17,19,28-trioxa-24-thia-13,30-diazaspiro[heptacyclo[12.9.6.1³,¹¹.0²,¹³.0⁴,⁹.0¹⁵,²³.0¹⁶,²⁰]triacontane-26,1'-isoquinoline]-4(9),5,7,15(23),16(20),21-hexaen-22-yl acetate is a very strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Ecteinascidin 743 is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Ecteinascidin 743 is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
