Descrizione generale

Chemical structure: taxoide

Applicazioni

Paclitaxel has been used to study its effects on tumor regression in mouse models of pancreatic ductal adenocarcinoma. Paclitaxel has also been used as an internal standard for chromatographic assays of docetaxel. Furthermore, paclitaxel has been used to analyze its effects on Caenorhabditis elegans embryos.

Azioni biochim/fisiol

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 is highly lipophilic. It serves as a substrate for p-glycoprotein, a multi-drug resistance protein. Paclitaxel is thus, less localized to the brain. Apart from its cytocidal action, paclitaxel is known to stimulate tumor invasion process.
