Common Name(1r,2s,3s,5s,8r,9r,10s,11s,13r,16s)-2,9,11,16-tetrakis(acetyloxy)-3-(2-hydroxypropan-2-yl)-6,10-dimethyl-5-{[(2e)-3-phenylprop-2-enoyl]oxy}-14-oxatetracyclo[8.6.0.0³,⁷.0¹³,¹⁶]hexadec-6-en-8-yl benzoate
DescriptionTaxchinin B 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. (1r,2s,3s,5s,8r,9r,10s,11s,13r,16s)-2,9,11,16-tetrakis(acetyloxy)-3-(2-hydroxypropan-2-yl)-6,10-dimethyl-5-{[(2e)-3-phenylprop-2-enoyl]oxy}-14-oxatetracyclo[8.6.0.0³,⁷.0¹³,¹⁶]hexadec-6-en-8-yl benzoate is found in Taxus cuspidata. (1r,2s,3s,5s,8r,9r,10s,11s,13r,16s)-2,9,11,16-tetrakis(acetyloxy)-3-(2-hydroxypropan-2-yl)-6,10-dimethyl-5-{[(2e)-3-phenylprop-2-enoyl]oxy}-14-oxatetracyclo[8.6.0.0³,⁷.0¹³,¹⁶]hexadec-6-en-8-yl benzoate was first documented in 2010 (PMID: 20170941). Based on a literature review very few articles have been published on Taxchinin B.
