Application: Paclitaxel semi-synthetic for peak identification EP Reference standard, intended for use in laboratory tests only as specifically prescribed in the European Pharmacopoeia.
Biochem/physiol Actions: Paclitaxel is a potent anti-neoplastic and anti-mitotic taxane drug, which binds to the N-terminus of β-tubulin and and stabilizes microtubules arresting the cell cycle at the G2/M phase. The microtubule damage induces apoptosis through a JNK-dependent pathway followed by a JNK-independent pathway, perhaps related to the activation of protein kinase A (PKA) or of Raf-1 kinase, resulting in phosphorylation of Bcl-2. A major metabolite via CYP2CB is 6α-hydroxypaclitaxel (6α-OHP).
Caution: Paclitaxel undergoes transesterification in methanol and hydrolyzes in aqueous solutions.
