Description4,12-bis(acetyloxy)-1,9,15-trihydroxy-10,14,17,17-tetramethyl-11-oxo-6-oxatetracyclo[11.3.1.0³,¹⁰.0⁴,⁷]heptadec-13-en-2-yl benzoate 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. 4,12-bis(acetyloxy)-1,9,15-trihydroxy-10,14,17,17-tetramethyl-11-oxo-6-oxatetracyclo[11.3.1.0³,¹⁰.0⁴,⁷]heptadec-13-en-2-yl benzoate is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Baccatin iii is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Baccatin III 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.
