Vinflunine (Javlor) is the first fluorinated microtubule inhibitor belonging to the Vinca alkaloids family. Vinflunine, at the lowest effective concentrations, interacts with the Vinca alkaloid binding site on tubulin, suppresses microtubule dynamics (switching at microtubule ends between phases of slow growth and rapid shortening) and microtubule treadmilling (growth at the plus end and shortening at the minus end of the microtubule), causes cell cycle arrest which appears on fluorescence-activated cell sorting analysis as a G2 + M phase arrest, and is associated with an accumulation of cells in mitosis leading to cell death via apoptosis. Vinflunine has been been approved for advanced or metastatic transitional cell carcinoma of the urothelial tract. Pierre Fabre submitted an extension to the EU authorisation to add treatment of advanced breast cancer.

Fadrozole (CGS 16949A) is a tetrahydroimidazole-pyridine derivative is a non-steroidal inhibitor of aromatase. In the third phase of clinical trials it was shown, that this drug has good therapeutic effect as a second-line treatment in postmenopausal women with metastatic breast cancer.

Pixantrone is a novel anthracenedione. It is a weak inhibitor of topoisomerase II. Pixantrone directly alkylates DNA forming stable DNA adducts and cross-strand breaks. Pixuvri is approved for the treatment of adult patients with multiply relapsed or refractory aggressive Non-Hodgkin lymphomas. It is used for patients whose cancer does not respond or has returned after they have received other chemotherapy treatments. The most frequent AE were seen in the blood (mainly neutropaenia), gastrointestinal (nausea, abdominal pain, constipation) and respiratory systems (cough, dyspnea). No drug-drug interaction studies have been submitted and no drug interactions have been reported in human subjects

3-Aminopropionitrile (Beta-amino-propionitrile, BAPN) is a toxic constituent from lathyrus plants. BAPN found in lathyrus odoratus (our more common garden sweet pea plant) is thought to be responsible for osteolathyrism due to irreversible inhibition of lysyl oxidase (LOX), an enzyme necessary for the covalent cross-linking of tropocollagen molecules during the maturation of mature collagen. BAPN demonstrated in antimetastatic and antimyelofibrotic activity in vivo due to inhibition of LOX.

Elliptinium is an antineoplastic agent, which was used in the treatment of metastatic breast cancer in France under the name Celiptium. The drug is known to intercalate into DNA and inhibit topoisomerase II. Several studies have demonstrated that this molecule can be oxidized, yielding a reactive electrophilic form, which is able to bind covalently to a nucleophilic biological molecule.

Vindesine (desacetyl vinblastine amide sulfate) is a synthetic derivative of vinblastine. Vindesine acts by causing the arrest of cells in metaphase mitosis through its inhibition tubulin mitotic funcitoning. Vindesine is an anti-neoplastic drug for intravenous use which can be used alone or in combination with other oncolytic drugs. Information available at present suggests that Eldisine as a single agent may be useful for the treatment of: acute lymphoblastic leukaemia of childhood resistant to other drugs; blastic crises of chronic myeloid leukaemia; malignant melanoma unresponsive to other forms of therapy; advanced carcinoma of the breast, unresponsive to appropriate endocrine surgery and/or hormonal therapy. Adverse effects associated with the use of vindesine include cellulitis and phlebitis, gastrointestinal bleeding, chills, and fever. It may increase the neuropathy associated with Charcot-Marie-Tooth syndrome. Vindesine may interact with mitomycin-C (brand name Mutamycin), causing acute bronchospasm within minutes or hours following administration. Phenytoin (brand name Dilantin) may also interact with vindesine, leading to decreased serum levels of phenytoin.

Pirarubicin is a new kind of anthracene nucleus broad-spectrum antitumor antibiotic. This compound was rapidly incorporated into tumor cells, inhibiting DNA polymerase alpha, DNA topoisomerase II and subsequently DNA synthesis. Inhibition of RNA synthesis was also noted. It is indicated as an antineoplastic agent for the treatment of the following diseases: head and neck cancer, breast cancer, gastric cancer, urothelial cancer, ovarian cancer, uterine cancer, acute leukemia, malignant lymphoma. Among the side effects, cardiac toxicity, alopecia and disturbance of the digestive organs were mild.

There is no available information related any biological and pharmaceutical application of ammonium tetrachlorozincate.

Hydroxytamoxifen (Afimoxifene) is an active metabolite of tamoxifen exerting estrogen receptor modulatory function. In addition, hydroxytamoxifen binds to regulates transcriptional activity of the estrogen-related receptor gamma. ASCEND Therapeutics, Inc. was developing TamoGel (4-hydroxytamoxifen gel) for a variety of estrogen-dependent conditions, including breast cancer, cyclic breast pain and gynecomastia.

Beta-sitosterol is one of the main dietary phytosterols found in plants which have a similar skeleton as cholesterol. In human clinical trials, beta-sitosterol has been shown to have cholesterol-lowering effects and to relieve symptoms of benign prostatic hyperplasia. There has been a large amount of basic research conducted for potential applications of beta-sitosterol in a diverse range of conditions including cervical cancer, breast cancer, cystic fibrosis, and others. Beta-sitosterol is available over the counter as a natural health supplement and is marketed for a wide range of applications including headaches, tuberculosis, allergies, cancers, fibromyalgia, lupus, asthma, hair loss and many others.
