Metabolite Identification
Common NameTriamcinolone acetonide 21-palmitate
Description2-{12-fluoro-11-hydroxy-6,6,9,13-tetramethyl-16-oxo-5,7-dioxapentacyclo[10.8.0.0²,⁹.0⁴,⁸.0¹³,¹⁸]icosa-14,17-dien-8-yl}-2-oxoethyl hexadecanoate belongs to the class of organic compounds known as gluco/mineralocorticoids, progestogins and derivatives. These are steroids with a structure based on a hydroxylated prostane moiety. Based on a literature review very few articles have been published on 2-{12-fluoro-11-hydroxy-6,6,9,13-tetramethyl-16-oxo-5,7-dioxapentacyclo[10.8.0.0²,⁹.0⁴,⁸.0¹³,¹⁸]icosa-14,17-dien-8-yl}-2-oxoethyl hexadecanoate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Triamcinolone acetonide 21-palmitate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Triamcinolone acetonide 21-palmitate 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.
