Identification
Common NameTaxine B
ClassSmall Molecule
DescriptionTaxine B is a cardiotoxic alkaloid found in Yew trees. It is significantly more toxic than its counterpart, taxine A, and has both negative inotropic and atrioventricular conduction delay effects. Taxine B induced AV conduction delay produces the classic increase in the electro-cardiographic QRS complex duration that is observed in people, pigs, and guinea pigs with yew toxicosis. The p wave may also be depressed or absent. Taxine B also acts as a class I antiarrhythmic drug and, thus, reduces cardiac contractility and the maximum rate of depolarization. (1).

Chemical Taxonomy
Description 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.
