Background: Nisin, an effective natural food preservative, is an antimicrobial peptide produced by Lactococcus lactis. Although it has been mainly studied and developed as a potential alternative for antibiotics, other pharmacological effects of the nisin including cytotoxic and anti-tumor activity have been attracted many attentions.Objectives: Here, we ...

cancer is a major cause of death worldwide and causes serious problems in human life. it is developed by uncontrolled growth of a cell or a group of cells. there are many difficulties in treatment of cancer and many researchers are involved in investigating for effective drugs to treat the disease. caryophyllaceae is a large family of about 86 genera and 2200 herbaceous or subshrub species. the...

Paclitaxel (PTX) is one of the most effective drugs used in treatment breast cancer. Nonetheless, appearance MDR1 (multidrug resistance 1) tumor cells has become a significant hindrance for efficacious chemotherapy. In this study, we show that expression level Egr-1 (early growth response gene-1) cancer tissues (from paclitaxel chemotherapy failure patients) and MCF-7/PTX (the cell line was res...

Two set of 2-aryl-5,6-dihydropyrrolo[2,1-a] isoquinolines were designed and synthesized to evaluate their biological activities as topoisomerase inhibitors. Cytotoxic activity of the synthesized compounds 4a-e and 7a-d was assessed against several human cancer cell lines, including MCF-7 (breast cancer cell), HepG2 (liver hepatocellular cells), A549 (adenocarcinomic human alveolar basal epithel...

there have been efforts to overcome the problem in treatment of cancer using medicinal plants. it has been shown that citrus essential oil of contains different terpens with antitumor activities. in this study we sought to determine the cytotoxicity of essential oils of iranian citrus limon (l.), c. medica (l.), c. sinsensis (l.) peels on cancer cell lines. essential oils were prepared by hydro...

A novel series of 2-methyl-3-phenylquinazolin-4-one derivatives were synthesized and biologically evaluated for their cytotoxic potential against MCF-7, HepG2, PC-3 cancer cells. Most the tested compounds showed reasonable safety in normal human skin melanocyte HFB4 cell line. Compound 4 potent cytotoxicity on Hep-G2 lines, while compound 9 MCF-7 line, whereas 10 12 lines using 5-fluorouracil a...
