Docetaxel Chemical Properties,Uses,Production

Indications and Usage

Docetaxel is a taxane, antineoplastic, and anticancer drug used to treat locally advanced or metastatic breast cancer, even after the failure of cisplatin therapy. Its anti-tumor efficacy has been proven in in vitro tests to be 1.3-12 times that of paclitaxel. Clinical studies have shown that it is more effective than paclitaxel against anthracycline resistant breast cancer. Docetaxel is currently the most effective for the second-line treatment of anthracycline resistant breast cancer. In single cell therapy and combined chemotherapy for non-small cell lung cancer, it is one of the most effective drugs. It can be used for cancer of the uterus, and to study antibiotics, cell biology, cell signaling, neuroscience, apoptosis, and cell cycles. It is also used to study hair loss caused by docetaxel chemotherapy, and to prevent and treat small-cell lung cancer in patients contraindicated for chemotherapy. It is also used to investigate the roles of hypoxia-inducible factors-1α and 2α in androgen-insensitive prostate cancer cells.

Mechanisms of Action

Docetaxel promotes microtubule stabilization by promoting the assembly of microtubule dimers into microtubules, and preventing depolymerization, thus blocking cells in the G2 and M stages, and inhibiting the mitosis and proliferation of cancer cells. Its pharmacological effects are stronger than those of paclitaxel, with 3 times the intracellular concentration and long retention time within the cell, and twice the microtubule affinity; As a microtubule stabilizer and assembly promoter, its activity is twice that of paclitaxel; as a microtubule depolymerization inhibitor, its activity is also twice that of paclitaxel.


In a pharmacokinetic study in which cancer patients took 20-115 mg/m2, when the dose was 75-115 mg/m2 over a 1-2 hour intravenous drip, AUC was correlated with dose. Its pharmacokinetic characteristics conform to a three-compartmental pharmacokinetic model, with α, β, and γ half-lives of 4, 36, and 11.1 hours respectively. The concentration of the initial phase decreased rapidly, indicating that the drug was distributed to the peripheral compartment. The latter phase is partly due to the relatively slow elimination of the drug from the compartment. Within an hour of intravenous infusion of 100 mg/m2 of paclitaxel, the average peak was 3.7 ug/ml, AUC was 4.6 ug/ml•h, and total clearance and steady-state distribution were 21 L/h/m2 and 113 L. In vitro studies have shown that it has a plasma protein binding rate of more than 94-97%, and dexamethasone does not affect its protein binding. Docetaxel and its metabolites are mainly excreted from feces. Fecal and urinary excretion accounted for 75% and 6% of the dose, and only a small part is excreted in original form. In vitro studies have shown that docetaxel is metabolized by CYP3A4 isoenzymes, which can be inhibited by CYP3A4 inhibitors.

Clinical Research

Genotoxicity: docetaxel induced fractures in CHO-K1 cellular chromosome aberration tests and mouse bone marrow micronucleus tests, but no mutagenicity was observed in Ames tests and CHO/HGPRT gene mutation tests. Reproductive toxicity: no damage to fertility upon intravenous injection 0.3 mg/kg in mice (calculated by body surface area, about 1/50 of the recommended clinical dosage), but could cause reduction in testicular weight. This result is correlated with the results of repeatedly administering it to rats and dogs for 10 cycles (administered once every 21 days, for 6 months); when the intravenous doses were 5 mg/kg and 0.375 mg/kg respectively (converted by surface area, 1/3 and 1/15 of the recommended clinical dose, respectively), testicular atrophy and degeneration were observed. Similar effects were also observed in rats when given low doses more frequently. When rats and rabbits were given ≥0.3 mg/kg/day and 0.03 mg/kg/day (converted from surface area, respectively equivalent to 1/50 and 1/300 of the clinically recommended dose) during organogenesis), embryonic and fetal toxicity was observed (manifesting as intrauterine death, absorbed fetus, and fetal weight loss and delayed ossification). The above dose may case maternal toxicity.

Drug Interactions

In vitro studies have found that CYP3A4 inhibitors may interfere with the metabolism of docetaxel, so it should be used with caution in combination with such drugs (such as ketoconazole, erythromycin, cyclosporine, etc.)

Adverse Reactions

1. Bone marrow suppression: neutropenia is the most common adverse reaction is usually severe (under 500/mm3). Reversible and does not accumulate. Fever and infection associated with neutropenia have been reported in the literature. Anemia can be seen in most cases, with rare severe thrombocytopenia. 2. Allergic reactions: some patients experience severe allergic reactions, characterized by hypotension and bronchospasm, requiring interruption of treatment. The patient can return to normal immediately after discontinuing treatment. Mild allergic reactions, such as blush (with or without itchy erythema), chest tightness, back pain, difficulty breathing, drug fever, or chills, occur in some patients. 3. Skin reactions are usually manifest as erythema, mainly local rashes on hands and feet, sometimes also on arms, face, and chest, sometimes accompanied by itching. Rashes usually occur within a week of infusion, but can return before the next infusion. Severe symptoms, such as peeling after skin rash, occur rarely. Fingernail (or toenail) lesions may occur, characterized by hyperpigmentation or thinning, and sometimes pain and nail loss. 4. Fluid retention: edema, and a few reported cases of pleural effusion, ascites, pericardial effusion, increased capillary permeability, and weight gain. Lower limb fluid retention after four cycles of treatment or cumulative dose of 400mg/m2 may develop into systemic edema, and weight gain of 3kg or more. After discontinuing treatment, fluid retention gradually disappears. Corticosteroids should be given to prophylactically reduce fluid retention. 5. Gastrointestinal reactions such as nausea, vomiting, or diarrhea may occur. 6. There have been reports of neurotoxicity in clinical trials. 7. Cardiovascular adverse reactions such as hypotension, sinus tachycardia, palpitations, pulmonary edema, and hypertension may occur. 8. Other adverse reactions may include: hair loss, weakness, mucositis, joint and muscle pain, hypotension, and reaction at injection site. 9. Patients with normal liver function have also experienced elevated transaminase during treatment. For those with elevated bilirubin, the relationship with docetaxel is still unclear.


1 Patients with a history of severe allergic sensitivity to docetaxel or polysorbate-80.
2 Patients with white blood cell count under 1500/mm3.
3 Patients with severe liver damage.


At present there is still insufficient strictly controlled clinical data for pregnant women. Patient who are a pregnant woman or become pregnant while using docetaxel should be informed of potential damage to the fetus and risk of miscarriage. Women who may become pregnant during treatment should use birth control. It is not clear whether docetaxel is excreted from human milk. Given that many drugs may be excreted from human milk, and that docetaxel may have serious adverse reactions for breastfeeding infants, mothers should stop breastfeeding before treatment.
The efficacy and safety of docetaxel in children has not yet been determined.


Docetaxel, a semi-synthetic product from the taxoid family, was launched in 1995 first in South Africa and subsequently in several other markets for the treatment of ovarian, breast and non-small cell lung cancers. Like the naturally occurring antitumor agent paclitaxel, the first marketed taxoid, docetaxel promotes both the rate and extent of tubulin assembly into stable microtubules and inhibits their depolymerization. It acts as a mitotic spindle poison and induces a mitotic block in proliferating cells. This mechanism of action for taxoids is unique from other classes of anticancer agents. Docetaxel was reported to be twice as potent as paclitaxel in several in vitro protocols and also exhibit higher cytotoxicity. Clinical trials are on going for docetaxel for other types of tumors including pancreatic, gastric, head and neck cancers and soft tissue sarcomas.

Manufacturing Process

Taxol, a material occurring in nature, and extracted from Taxus brevifolia (i.e. the Pacific yew tree). It consists of the A, B and C variants. Taxol is not water soluble, thereby complicating its delivery in vivo for therapeutic purposes.
A sample of Taxol (14.7 g, 17 mmol) was dissolved in pyridine (150 mL) and chlorotriethylsilane (23.03 g, 147 mmol) was added. The reaction was stirred at 25°C under N2. After 20 hours the reaction appeared complete by TLC analysis (7% MeOH/CH2Cl2). The mixture was concentrated to remove the pyridine. The residue was dissolved in CH2Cl2 and washed with water, 10% CuSO4, NaHCO3 and brine successively. The organic layer was dried over MgSO4, and concentrated to yield 20.89 g of the crude 2,7'-bis(triethylsilyl) Taxol. A portion of crude 2',7-bis(triethylsilyl) Taxol (14.50 g, 13.4 mmol) was dissolved in dry THF (150 mL). Zirconocene chloride hydride (7.75 g, 30.2 mmol) was added. The reaction was stirred at 25°C under N2. After 20 hours the reaction appeared complete by TLC analysis. The mixture was poured intocold hexanes, and the resulting precipitated Zr complexes were filtered off. The solution was concentrated to yield 17 g of the crude 2,7'-bis(triethylsilyl) Taxol imine. A portion of crude 2',7-bis(triethylsilyl) Taxol imine (8.36 g) was dissolved in 1% HCl/EtOH (180 mL) and the reaction was stirred at 25°C for 20 hours. The reaction appeared complete by TLC analysis. The mixture was poured into 800 mL of water and washed with hexane (180 mL times 3). The aqueous layer was neutralized with NaHCO3 to pH=7.0. The product was extracted with CH2Cl2. The organic layer was removed and concentrated to a solid. Silica gel chromatography (5% MeOH/CH2Cl2) yielded Taxol primary amine (2.41 g, 52% overall yield based on 5 g of Taxol used). Melting point 160°C-162°C.
A sample of Taxol primary amine (100 mg, 0.13 mmol) was dissolved in CH2Cl2 (10 mL) and HCl (15 mM in Et2O; 10 ml, 150 mmol) was added. The reaction was stirred at 25°C for 2 minutes. The mixture was concentrated to remove the solvents. The residue was redissolved in CH2Cl2 and precipitated in hexane. Filtration yielded 85 mg of Taxol PA (PA-primary amine) HCl (83%). Melting point 65°C. A sample of Taxol PA HCl (50 mg, 0.064 mmol) was dissolved in 0.5 ml of water. It was neutralized to pH 7.0 by addition of saturated NaHCO3, followed by extraction with CH2Cl2. The organic layer was concentrated and chromatographed (3% MeOH/CH2Cl2was used as mobile phase) to yield 30 mg of Taxol primary amine (63% yield). The 1H NMR and LRMS data agree well with a standard sample of Taxol primary amine.
Trimethylsilyl- and trichlorethoxycarbonyl-protecting group can be used. A mixture of impure Taxol A, B, C can be converted Taxol primary amine, which then can be converted to Taxol A or docetaxel.
