Common Name7-Epi-Taxol
DescriptionN-(3-{[4,12-bis(acetyloxy)-2-(benzoyloxy)-1,9-dihydroxy-10,14,17,17-tetramethyl-11-oxo-6-oxatetracyclo[11.3.1.0³,¹⁰.0⁴,⁷]heptadec-13-en-15-yl]oxy}-2-hydroxy-3-oxo-1-phenylpropyl)benzenecarboximidic acid belongs to the class of organic compounds known as taxanes and derivatives. These are diterpenoids with a structure based either on the taxane skeleton, or a derivative thereof. In term of phytochemistry, several derivatives of the taxane skeleton exist: 2(3->20)-abeotaxane, 3,11-cyclotaxane, 11(15->1),11(10->9)-abeotaxane, 3,8-seco-taxane, and 11(15->1)-abeotaxane, among others. More complex skeletons have been found recently, which include the taxane-derived [3.3.3] propellane ring system. Based on a literature review very few articles have been published on N-(3-{[4,12-bis(acetyloxy)-2-(benzoyloxy)-1,9-dihydroxy-10,14,17,17-tetramethyl-11-oxo-6-oxatetracyclo[11.3.1.0³,¹⁰.0⁴,⁷]heptadec-13-en-15-yl]oxy}-2-hydroxy-3-oxo-1-phenylpropyl)benzenecarboximidic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 7-epi-taxol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 7-Epi-Taxol 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.
