Adriamycin Chemical Properties,Usage,Production

Antitumor antibiotics

Adriamycin is a kind of anthracycline antitumor antibiotics produced by Streptomyces peucetius sub sp caesius, belonging to cell cycle non-specific drug (CCNSA). Cells of S and M phases are most sensitive to it. Its hydrochloride appears as orange needle crystal. The melting point is 204 ~ 205 ℃. It is easily soluble in water, ethanol and methanol. The aqueous solution is stable and stays constant at 5 ° C for 1 month but is not stable at higher temperatures or in acidic or alkaline solutions. The acidic aqueous solution is orange, neutral orange-red, alkaline (pH> 9) purple-blue. It is insoluble in acetone, benzene, petroleum ether, ether and chloroform. It is an antitumor antibiotic isolated from the actinomycetes culture. The mechanism of action is similar to daunorubicin, which has a broader anti-tumor spectrum and a higher therapeutic index. It is clinically applied for the treatment of acute and chronic lymphocytic leukemia and solid tumor leukemia, lymphoma, breast cancer, ovarian cancer, soft tissue sarcoma, osteogenic sarcoma, rhabdomyosarcoma, Ewing's sarcoma, nephroblastoma, neuroblastoma, gastric cancer, pancreatic cancer, liver cancer, prostate cancer, head and neck squamous cell carcinoma, testicular cancer, lung cancer, bladder cancer, medullary thyroid carcinoma and sarcoma. This product can cause myelosuppression, gastrointestinal reactions and cardiac toxicity. 4'-Epirubicin (4'-epi-adriamycin) is the reverse configuration of the C4 hydroxyl in the glycosyl group of Adriamycin. Its anti-tumor effect is similar to that of Adriamycin, but its cardiotoxicity is low. 4'-deoxyadriamycin (4'-deoxyadriamycin) has a different antitumor spectrum of animal tumors with doxorubicin with lower damage to the heart compared to doxorubicin.

Pharmacological effects

This product belongs to anthracycline antineoplastic drugs, having similar structure to daunorubicin with the only difference being an H-hydroxy substitution in the side chain 14 carbon atoms. It has both fat-soluble anthracene ring ligand and water-soluble daunosamine. It also has acidic phenolic hydroxyl and basic amino group, thus having a strong anticancer pharmacological activity. Adriamycin is obtained from the culture Str. Pe-ucetius var. Caesius. Owing to the quinone-hydroquinone structure on the anthracene ring ligand in the molecule, it has the ability of accepting electrons and providing neutrons, to be inserted between adjacent base pairs of DNA, generating active free radicals, unwinding and breaking DNA double helix. It can further inhibit the activity of the nucleic acid template, interfering with the transcription process to prevent mRNA synthesis. In addition it may cause cell membrane rupture, exhibiting cytotoxicity, belonging to a cell cycle non-specific drug. This product has the function of forming superoxide radicals, and has a special role in the destruction of cell membrane structure and function. It is effective in the targeting all stages of the cells, but being of highest efficient in the treatment of the early S phase cells, followed by M, with the G1 phase being most insensitive to it. It can delay the G1, S and G2 phase. However, the maximum cytotoxicity occurs in S phase and is more sensitive to early S and M phase cells. Adriamycin can cause chromosome aberrations in cells and increase the exchange rate of chromatids.
This product has poor oral absorption, and should be administrated by only intravenous injection. Its plasma protein binding rate is low. It can rapidly disappear from the blood after injection, being widely distributed in the heart, stomach, lung, liver and spleen organizations, but no penetrating through the blood-brain barrier. Plasma attenuation curve is divided into three phases with half-life being 12 minutes, 3.3 hours and 30 hours, respectively. It is mainly subject to liver metabolism with the main metabolite being doxorubicin alcohol, having a considerable anti-cancer activity. Approximately 40% to 50% of the dose is excreted by bile after 7 days of administration, of which 50% is prototype and 23% is active metabolite. 5% to 10% of urine excreted. Upon liver and renal insufficiency, doxorubicin stay in the body for longer with the clear curve exhibiting heterogeneous phases and its three-phase T1 / 2 were 0.5 hours, 3 hours and 40 to 50 hours, respectively. It is clinical mainly for the treatment of acute or chronic leukemia, Hodgkin and non-Hodgkin's lymphoma and malignant lymphoma. Daunorubicin resistant tumors are still sensitive to doxorubicin. It also has certain efficacy in the treatment of Ewing's tumor, osteosarcoma, soft tissue tumor, lung cancer, choriocarcinoma, breast cancer, bladder cancer, thyroid cancer and soft tissue tumors. It combination with cytarabine, vincristine and fluorouracil can increase its efficacy. Tumor cells are resistant to doxorubicin. Drug-resistant cells, compared to the sensitive cells, have lower permeability of the cell membrane, decreased cellular uptake doxorubicin reduction, and can actively discharge doxorubicin. Daunorubicin resistant cells may also be cross-resistant to doxorubicin.

Adverse reactions

A dose of more than 500mg / m2, 25% to 30% can possibly lead to ECG abnormalities, arrhythmia and decreased cardiac function. There are few cases of congestive heart failure, myocardial degeneration, local necrosis, and even death. 60% to 80% may have myelosuppression, manifested as leukopenia, thrombocytopenia and anemia with reaching minimum in 7 to 10 days and recovering at the first 4 weeks. In addition, there may be nausea and vomiting, mouth ulcers. Similar to daunorubicin, side effects of doxorubicin include cardiotoxicity, bone marrow suppression, nausea, vomiting and stomatitis as well as hair loss. Early signs of cardiac toxicity exhibit temporary ECG changes with the majority undergoing self-remission. Late (chronic) cardiotoxicity, also known as delayed cardiomyopathy that is dose related, is irreversible serious myocardial disease with severe cases being lethal. Therefore, heart disease and hypertension patients should use with caution. There are phlebitis, skin pigmentation and liver damage. Cardiotoxicity patients can administrate vitamin E, vitamin C, coenzyme Q10, N-acetyl cysteine and selenium preparations. Heart failure patients may be given digitalis preparations and diuretics.

Medicine interactions

• Cross-resistant to daunorubicin, vincristine and actinomycin D.
• Synergistic effect with cyclophosphamide, fluorouracil, methotrexate, chlorelimide, cisplatin and nitrosoureas.
• Used with caution during live virus vaccination.
• Combination with azathioprine or mercaptopurine can increase doxorubicin liver toxicity.

Chemical Properties

Adriamycin is an orange to red cake-like or needle-like crystalline solid.

Originator

Adriblastina,Farmitalia,Italy,1971

Uses

Doxorubicin is one of the most effective neoplastic drugs, and is mainly used in combination with other drugs for treating solid tumors. This drug is used for leukemia, various sarcomas, practically every type of cancer, neuroblastomas, leukoses, and lymphomas.

Uses

Doxorubicin USP (Adriamycin) is used to traet soft-tissue and osteogenic sarcomas; Hodgkin’s disease; non-Hodgkin’s lymphomas; acute leukemia; cancer of thyroid, breast, lung, genitourinary (GU) tract; Wilm’s tumor; neuroblastoma.

Uses

Doxorubicin (adriamycin) is the most extensively studied of a family of highly fluorescent anthracycline antibiotics produced by several Streptomyces species, first reported in 1967 and later approved for human therapeutic use as an antitumour agent for the treatment of a wide range of cancers. Doxorubicin also exhibits anti-HIV and antibacterial activity. The mode of action of doxorubicin is thought to be due to intercalation of DNA and inhibition of nucleic acid synthesis.

Definition

ChEBI: Doxorubicin is a deoxy hexoside, an anthracycline, an anthracycline antibiotic, an aminoglycoside, a member of tetracenequinones, a member of p-quinones, a primary alpha-hydroxy ketone and a tertiary alpha-hydroxy ketone. It has a role as an Escherichia coli metabolite. It is a conjugate base of a doxorubicin(1+). It derives from a hydride of a tetracene.

Indications

Doxorubicin binds tightly to DNA by its ability to intercalate between base pairs and therefore is preferentially concentrated in nuclear structures. Intercalation results in steric hindrance, hence production of single-strand breaks in DNA and inhibition of DNA synthesis and DNA-dependent RNA synthesis. The enzyme topoisomerase II is thought to be involved in the generation of DNA strand breaks by the anthracyclines. Cells in S-phase are most sensitive to doxorubicin, although cytotoxicity also occurs in other phases of the cell cycle.

Manufacturing Process

Two 300 ml Erlenmeyer flasks, each containing 60 ml of the following culture medium for the vegetative phase, were prepared: peptone 0.6%; dry yeast 0.3%; hydrated calcium carbonate 0.2%; magnesium sulfate 0.01%; the pH after sterilization was 7.2. Sterilization has been effected by heating in autoclave to 120°C for 20 minutes. Each flask was inoculated with a quantity of mycelium of the mutant F.I.106 (the new strain thus obtained has been given the code F.I.106 of the Farmitalia microbiological collection and has been called Streptomycespeucetius var. caesius) corresponding to 1/9 of a suspension in sterile water of the mycelium of a 10 day old culture grown in a big test tube on the following medium: saccharose 2%; dry yeast 0.1%; bipotassium phosphate 0.2%; sodium nitrate 0.2%; magnesium sulfate 0.2%; agar 2%; tap water up to 100%. The flasks were then incubated at 28°C for 48 hours on a rotary shaker with a stroke of 30 mm at 220 rpm.，
2 ml of a vegetative medium thus grown were used to inoculate 300 ml Erlenmeyer flasks with 60 ml of the following medium for the productive phase: glucose 6%; dry yeast 2.5%; sodium chloride 0.2%; bipotassium phosphate 0.1%; calcium carbonate 0.2%; magnesium sulfate 0.01%; ferrous sulfate 0.001%; zinc sulfate 0.001%; copper sulfate 0.001%; tap water to 100%. The glucose was previously sterilized separately at 110°C for 20 minutes. The resulting pH was 7. This was sterilized at 120°C for 20 minutes and incubated at 28°C under the same conditions by stirring, as for the vegetative media.
The maximum concentration of the antibiotic was reached on the 6th day of fermentation. The quantity of adriamycin produced at this time corresponds to a concentration of 15 μg/ml.

Therapeutic Function

Cancer chemotherapy

Biological Activity

doxorubicin is a semi-synthesized anticancer agent derived from bacterial culture. [1] it is an anthracycline antibiotic. it is been widely used in blood cancers, solid tumors and sarcomas.doxorubicin intercalates into dna double strand and inhibits the progression of dna topoisomerase ii, stopping replication process. [2] doxorubicin also induces histone eviction from open chromatin, causing dna damage and epigenetic deregulation. [3]doxorubicin is administrated intravenously. approximately 75% of doxorubicin and its metabolites bind to plasma protein. doxorubicin does not cross blood brain barrier. 50% of the drug is eliminated unchanged from the body mainly though bile excretion. the remaining undergoes one-electron reduction, two-electron reduction, and deglycosidation. the major metabolite is a potent membrane ion pump inhibitor, which is associated with cardiomyopathy. [4]

Mechanism of action

Doxorubicin is not absorbed orally, and because of its ability to cause tissue necrosis must not be injected intramuscularly or subcutaneously. Distribution studies indicate rapid uptake in all tissues except the CNS. Extensive tissue binding, primarily intranuclear, accounts for the prolonged elimination half-life.The drug is extensively metabolized in the liver to hydroxylated and conjugated metabolites and to aglycones that are primarily excreted in the bile.

Clinical Use

Doxorubicin is one of the most effective agents used in the treatment of carcinomas of the breast, ovary, endometrium, bladder, and thyroid and in oat cell cancer of the lung. It is included in several combination regimens for diffuse lymphomas and Hodgkin’s disease. Doxorubicin can be used as an alternative to daunorubicin in acute leukemias and is useful in Ewing’s sarcoma, osteogenic sarcoma, soft-tissue sarcomas, and neuroblastoma. Some activity has been reported in non–oat cell lung cancer, multiple myeloma, and adenocarcinomas of the stomach, prostate, and testis.

Side effects

The most important toxicities caused by doxorubicin involve the heart and bone marrow.Acutely, doxorubicin may cause transient cardiac arrhythmias and depression of myocardial function. Doxorubicin may cause radiation recall reactions, with flare-ups of dermatitis, stomatitis, or esophagitis that had been produced previously by radiation therapy. Less severe toxicities include phlebitis and sclerosis of veins used for injection, hyperpigmentation of nail beds and skin creases, and conjunctivitis. Because of its intense red color, doxorubicin will impart a reddish color to the urine for 1 or 2 days after administration.

Safety Profile

Confirmed carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Poison by intraperitoneal, subcutaneous, parenteral, and intravenous routes. Human systemic effects by intravenous route: cardiac myopathy including infarction, nausea or vomiting, and effects on the hair. An experimental teratogen. Other experimental reproductive effects. Human mutation data reported. When heated to decomposition it emits very toxic fumes of NO, and HCl
