Common NameMilataxel
DescriptionMilataxel, also known as MAC-321 or TL139 CPD, 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 a significant number of articles have been published on Milataxel. This compound has been identified in human blood as reported by (PMID: 31557052 ). Milataxel is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Milataxel 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.
