In a systematic effort to identify a potent antiproliferative agent, four complexes of vanadium containing maltol and deferiprone ligands were synthesized and evaluated for their cytotoxic activity against five human and animal cancer cell lines, including human breast cancer cells (MCF-7), human cervix epithelial carcinoma (HeLa), human colon cancer cell line (HT-29), human leukemia cell line ...

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...

Background and objectives: Because of the importance of breast cancer as a first cause of morbidity and mortality among females, also the limitation of chemotherapy and based on literature of the use of herbal medicines against cancer, the current study was aimed to determine the efficacy of Berbers vulgaris fruit ethanol extract against MCF-7 breast cancer cell line. ...

objective: silybin is a polyphenol with anti-oxidant and anti-cancer properties. the poor bioavailability of some polyphenols can be improved by binding to phosphatidylcholine. in recent years, studies have been conducted to evaluate the anti-cancer effect of silybin. we studied the effect of silybin and silybin-phosphatidylcholine on esr1 and esr2 gene expression and viability in the t47d brea...

objective(s):multidrug resistance (mdr) of cancer cells is a major obstacle to successful chemotherapy. overexpression of breast cancer resistance protein (bcrp) is one of the major causes of mdr. in addition, it has been shown that pi3k/akt signaling pathway involves in drug resistance. therefore, we evaluated the effects of novel approaches including sirna directed against bcrp and targeted t...

cancer is a group of diseases characterized by uncontrolled proliferation of abnormal cells. because of the severe side effects and resistance to the traditional chemotherapeutic agents, the necessity for discovery of new anticancer drugs is a crucial topic. in the present study we synthesized new derivatives of 2-(4-fluorophenyl)- n -halophenylacetamide and assessed their cytotoxicity against ...

Introduction: Breast cancer is the most common cause of cancer-related death among women. Recently, extremely low-frequency electromagnetic field (ELF-EMF) has been proposed as a new interfering agent with future therapeutic potentials. Many studies have revealed that cellular processes such as apoptosis in breast cancer are affected by ELF-EMFs. However, more researches are needed to clarify t...
