1. Présentation du produit

Docetaxel 99% is a highly purified semi-synthetic taxane API widely used in anti-tumor formulations. Known for its strong microtubule-stabilizing activity, Docetaxel is a key ingredient in oncology products targeting breast cancer, NSCLC, prostate cancer, gastric cancer, head & neck cancers, and more.

At Zhonghong Biotech, we supply pharmaceutical-grade Docetaxel 99% manufactured under GMP-aligned production standards, with complete documentation including COA, MSDS, chromatographic profiles, method validation, and regulatory support files.

Our raw material is sourced from high-quality 10-deacetylbaccatin III (10-DAB), ensuring stable production, reliable batch consistency, and competitive factory-direct pricing for industrial buyers.

2. Source et origine botaniques

Docetaxel is a semi-synthetic derivative of paclitaxel precursors isolated from:

• Taxus chinensis,

• Taxus yunnanensis,

• Taxus brevifolia,

• et autres Taxus espèces.

Nous utilisons 10-DAB (10-Deacetylbaccatin III) extracted from cultivated Taxus needles and branches. The semi-synthetic route ensures sustainability (no bark harvesting) and stable large-scale supply.

4. Benefits & Mechanism of Action

1) Stabilizes Microtubules

Docetaxel enhances tubulin polymerization and prevents depolymerization, arresting cancer cells in the G2/M phase.
Supported by PubMed studies.

2) Broad Antitumor Activity

Indicated in multiple solid tumors, including:

• Breast cancer

• Prostate cancer

• CBNPC

• Gastric cancer

• Head & neck cancer

3) Stronger Activity than Paclitaxel

Docetaxel shows:

• Higher cellular uptake

• Higher binding affinity to tubulin

• Prolonged microtubule stabilization

4) Synergy

Used in combination with:

• Carboplatin

• Cisplatin

• Doxorubicin

• Capecitabine

5. Health & Clinical Relevance

Docetaxel is included in global oncology guidelines:

• NCCN Guidelines

• FDA-approved indications

• EMA-approved oncology products

Mechanisms include:

• Induire l'apoptose

• Inhibiting angiogenesis

• Blocking cancer metastasis
