General description

Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards

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).


Paclitaxel undergoes transesterification in methanol and hydrolyzes in aqueous solutions.

Analysis Note

These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.
