Paclitaxel Chemical Properties,Uses,Production

Indications and Usage

Paclitaxel is a monomeric diterpene compound extracted from Chinese yew bark and is a complicated secondary metabolite. Stage II-III clinical studies show that paclitaxel is most suitable for ovarian and breast cancer, and has certain efficacy in treating prostate cancer, lung cancer, colorectal cancer, melanoma, head and neck cancer, esophageal cancer, germ cell tumors, endometrial cancer, lymphoma, brain tumors, bladder cancer, upper gastrointestinal cancer, small cell and non-small cell lung cancer.

Mechanisms of Action

Paclitaxel is currently the only known drug that can promote microtubule polymerization and stabilize polymerized microtubules. It can only form on polymerized microtubules and does not react with non-polymerized microtubule protein dipolymers. After coming in contact with paclitaxel, cells will accumulate a large number of microtubules within themselves, which disrupts cell functions, especially cell division, which is forced to cease at the mitotic stage.

Warnings and Precautions

1. Hermatological toxicity: the main factor in increased dosage limitations; when white blood cells are below 1500/mm3, supplement with G-CSF; when platelets are below 30000/mm3, transfuse component blood.
2. Allergic reaction: Aside from preconditions, if there are only minor symptoms such as flushed face, skin reactions, slightly increase heart rate, slightly lowered blood pressure, etc., do not stop treatment and decrease injection speed. If there are serious reactions such as hypotension, vascular edema, difficulty breathing, measles, etc., stop treatment and treat accordingly. Patients with serious allergic reactions should not use paclitaxel in the future.
3. Nervous system: Common reactions include numb toes. Approximately 4% patients, especially with high dosage, experience significant sensory and motor difficulty and decreased tendon reflex. There have been individual reports of epilepsy.
4. Cardiovascular: Transient tachycardia and hypotension are common and do not usually require attention. However, monitor closely during first hour of injection. Afterwards, only patients with serious injection difficulty require hourly check-ins.
5. Join and muscle: Approximately half of the patients will experience some joint and muscle pain within the first 2-3 days following injection, which is related to dosage, and usually subsides after a couple days. Patients who are also administered G-CSF will experience heightened muscle pain.
6. Liver and gall: As paclitaxel is mainly excreted through bile, patients with liver and gall diseases must be monitored carefully. Among thousands of cases, 8% of patients experienced increased bilirubin, 23% experienced increased alkaline phosphatase, and 18% experienced increased glutamic-oxalacetic transaminase. However, there is currently no evidence indicating that paclitaxel causes any severe liver damage.
7. Other: Digestive tract reactions are common but rarely severe, with few cases of diarrhea and mucosa infection. Slight alopecia is also common.

Chemical Properties

White Powder


glucocorticoid, antiinflammatory


An antineoplastic. Used in the study of structure and function of microtubles into tubulin. Paclitaxel is now used to treat patients with lung, ovarian, breast cancer, head and neck cancer, and advanc ed forms of Kaposi's sarcoma. Paclitaxel is a mitotic inhibitor used in cancer chemotherapy.


Tool in study of structure and function of microtubules.

General Description

Needles (from aqueous methanol) or fine white powder. An anti-cancer drug.

Air & Water Reactions

May be sensitive to prolonged exposure to moisture. .

Health Hazard

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Fire Hazard

Flash point data for Paclitaxel are not available. Paclitaxel is probably combustible.

Biological Activity

Antitumor agent; promotes and stabilizes tubulin polymerization, causing cell cycle arrest. Induces autocatalytic activation of caspase-10 in CCRF-HSB-2 cells, triggering apoptosis.
