Description

General description

Chemical structure: taxoide

application

Paclitaxel has been used as a component of the dechorionation buffer for Gryllus bimaculatus eggs. Paclitaxel has also been used for studying its effect on the movement of all-trans retinoic acid (ATRA) differentiated NB4 cells.

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).
