Since malignant cells often have a high demand for iron, we hypothesize that breast cancer cells may alter the expression of iron transporter genes including iron importers [transferrin receptor (TFRC) and solute carrier family 11 (proton-coupled divalent metal ion transporters), member 2 (SLC11A2)] and the iron exporter SLC40A1 (ferroportin), and additionally that the growth of breast cancer c...

The cytotoxicity of 27 benzanilides and dithiobenzanilides built on a stilbene scaffold and possessing various functional groups in aromatic rings previously described for their spasmolytic properties was assayed on three human cancer cell lines (A549 -lung adenocarcinoma, MCF-7 estrogen dependent breast adenocarcinoma and MDA-MB-231 estrogen independent breast adenocarcinoma) and 2 non-tumorig...

Cytotoxic activity of gaillardin, a sesquiterpene lactone isolated from Inula oculus-christi L. (Asteraceae), was assessed in the human breast adenocarcinoma cell line MCF-7, human hepatocellular carcinoma cell line HepG-2, human non-small cell lung carcinoma cell line A-549, and human colon adenocarcinoma cell line HT-29, resulting in IC50 values of 6.37, 6.20, 4.76, and 1.81 microg/mL, respec...

OBJECTIVE The aim of this study was to explore the therapeutic effect of natural killer (NK) cells on human doxorubicin-sensitive and resistant breast adenocarcinoma. METHODS Human doxorubicin-sensitive and resistant breast cancer cell lines (MCF-7 and MCF-7/ADR) were tagged with renilla luciferase (Rluc) (MCF-7/RC and MCF-7/ADR/RC). NK cells were tagged with enhanced firefly luciferase (effl...

the assessment of the degree or rate of cellular proliferation and cell viability is critical for the assessment of the effects of drugs on both normal and malignant cell populations. in the present study, a few novel 3-substituted derivatives of 2-indolinones were synthesized by condensation of substituted oxindole or isatin derivatives with appropriate aldehydes or primary aromatic amines res...

Simple and efficient synthesis of quebecol and a number of its analogs was accomplished in five steps. The synthesized compounds were evaluated for antiproliferative activities against human cervix adenocarcinoma (HeLa), human ovarian carcinoma (SK-OV-3), human colon carcinoma (HT-29), and human breast adenocarcinoma (MCF-7) cancer cell lines. Among all the compounds, 7c, 7d, 7f, and 8f exhibit...

Herbs and spices have been traditionally used for prevention and cure of many diseases. Hence, the present study was aimed to investigate the effects of aqueous and alcoholic extract of four different spices (asafoetida, ginger, cinnamon and cardamom) extracts on human breast adenocarcinoma cell line (MCF) and HEP-G2 cancer cell lines through in-vitro growth inhibitory assay. Both aqueous and a...

The synthesis and characterization of four compounds [M(η5-C5Me5)(N^N)Cl]PF6 [N^N=4,7-dichloro-1,10-phenanthroline with M=Rh, 1, M=Ir, 2, N^N=4'-(4-chlorophenyl)-2,2':6',2''-terpyridine in the κ2N,N'-coordination mode 3, 4] are described. All were characterized by spectroscopic means their molecular structures crystal confirmed single-crystal X-ray diffraction studies. cytotoxicity all was eval...

marine streptomyces are prolific producers of majority of bioactive secondary metabolites which are used in pharmaceutical industry as effective drugs against life threatening diseases. the cytotoxic activity of the pure compound 1, 2- benzene dicarboxylic acid, mono 2- ethylhexyl ester (dmehe) from marine derived actinomycete streptomyces sp. vitsjk8 was investigated against mouse embryonic fi...

A biocompatible polyester dendrimer composed of the natural metabolites, glycerol and succinic acid, is described for the encapsulation of the antitumor camptothecins, 10-hydroxycamptothecin and 7-butyl-10-aminocamptothecin. The cytotoxicity of the dendrimer-drug complex toward four different human cancer cell lines [human breast adenocarcinoma (MCF-7), colorectal adenocarcinoma (HT-29), non-sm...
