BACKGROUND Biochanin A and formononetin are O-methylated isoflavones that are isolated from the root of Astragalus membranaceus, and have antitumorigenic effects. Our previous studies found that formononetin triggered growth-inhibitory and apoptotic activities in MCF-7 breast cancer cells. We performed in vivo and in vitro studies to further investigate the potential effect of biochanin A in pr...

A new group of 4-(Imidazolylmethyl) quinoline derivatives possessing a methylsulfonyl COX-2 pharmacophore at the para position of the C-2 phenyl ring were designed and synthesized as selective COX-2 inhibitors and in-vitro anti breast cancer agents. In-vitro COX-1 and COX-2 inhibition studies showed that all the compounds were potent and selective inhibitors of the COX-2 isozyme with IC50 value...

PURPOSE The human TESTIN (TES) gene is a putative tumor suppressor gene in the fragile chromosomal region FRA7G at 7q31.1/2 that was reported to be altered in leukemia and lymphoma cell lines. In this report, we investigated the effect of TES gene expression in vivo to evaluate a possible role of TES gene in human cancer. EXPERIMENTAL DESIGN We have analyzed the expression of TES gene in a pa...

C35 is a novel tumor biomarker associated with metastasis progression. To investigate the interaction factors of C35 in its high expressed breast cancer cell lines, we constructed bait recombinant plasmids of C35 gene and T47D cell cDNA library for yeast two-hybrid screening. Full length C35 sequences were subcloned using RT-PCR from cDNA template extracted from T47D cells. Based on functional ...

background: many natural products from plants have been recognized to exert anticancer activity. in this study, ethanolic extracts of selected medicinal herbs from iranian flora including alyssum homolocarpum fisch. (from seeds), urtica dioica l. (from aerial parts), cichorium intybus l. (from roots) and solanum nigrum l. (from fruits), were evaluated for their cytotoxic effect on different cel...

Multi drug resistance (MDR) is a serious obstacle in the management of breast cancer. Therefore, overcoming MDR using novel anticancer agents is a top priority for medicinal chemists. It was found that dihydropyridines lacking calcium antagonistic activity (e.g acridinediones) possess MDR modifier potency. In this study, the capability of four novel acridine-1,8-diones derivatives 3a-d were eva...

Abstract Breast and cervical cancers are the leading cause of death in women, chemotherapy with cytotoxins is usual treatment. This study evaluated cytotoxicity guava leaf ( Psidium guajava L.) extracts as an alternative chemotherapeutic drug. Although many studies related to cytotoxic effects on cancer cells have been reported, fractions human breast (T47D, MCF-7, HeLa) never evaluated. Herein...

A new series of anti-cancer agents based on 1,2-diaryl-5,6-dihydropyrrolo[2,1-a]isoquinoline scaffold containing N,N-diethylamino‌ethoxy, piperidinyl‌ethoxy or morpholinyl‌ethoxy group at the para position of the C-2 phenyl ring were synthesized and their cytotoxic activities were assessed against several human cancer cell lines including MCF-7 (ER positive breast cancer cell), MDA-MB231 (ER-ne...

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 breas...
