Phage display technologies were used to produce singlechain antibodies (scFv) against breast cancer cell line (MCF-7). The mouse B cell hybridoma line C3A8 was the starting material, which generates a monoclonal antibody against breast cancer cells (MCF-7). The best candidate scFv sequences, based on (ELISA) screening data were sub-cloned into HB2151 host strain. The scFv gene was expressed in ...

A one-step synthetic procedure using the reaction of potassium bis(oxalato)platinate(II) with the corresponding N6-benzyladenosine derivative (nL) provided the [Pt(ox)(nL)₂]∙1.5H₂O oxalato (ox) complexes 1-5, involving the nL molecules as monodentate coordinated N-donor ligands. The complexes were thoroughly characterized by elemental analysis, multinuclear (¹H, ¹³C, ¹⁵N, 1¹⁹⁵Pt) and two dimens...

With the development of nanotechnology, emergence new anti-tumor techniques using nanoparticles such as magnetic hyperthermia and magneto-mechanical activation have been subject much attention study in recent years, anticancer tools. Therefore, purpose current vitro was to investigate cumulative effect a combination these two techniques, against breast cancer cells. After 24 h incubation, human...

Cancers, particularly, breast cancer is one of the deadliest disease in women and requires to be treated with lowest side-effects toxicity. Quinazolinone Benzimidazole nucleus are privileged reported anti-cancer activity. Hence, combined derivatives 3-((1H-Benzo[d]imidazol-2-yl)methyl)-2-phenylquinazolin-4(3H)-one E(1-8) were prepared tested for cytotoxicity on MCF-7 cell line. Compound E6 show...

The aim of the present study was to establish a tamoxifen-resistant cell line (MCF-7/TAM-R) and to investigate the therapeutic effect of G47Δ on this cell line both in vitro and in vivo. In the present study, the MCF-7/TAM-R monoclonal subline was established after exposing MCF-7 cells to tamoxifen for 21 days. Then, it was compared with a wild-type MCF-7 subline (MCF-7W), which was not treated...

A new class of tricyclic heterocycles 4H-benzo[g][1,2,3]triazolo[5,1-c][1,4]oxazocines was synthesized through a Knoevenagel condensation/azide-alkyne cycloaddition reaction cascade in one-pot operation. These eight membered ring containing heterocycles exhibited moderately high anticancer activity against four cancer cell lines; human cervix cancer cell line (HeLa), human prostate cancer cell ...

BACKGROUND In order to develop experimental immunotherapy for prostate and breast cancer it is of outmost importance to have representative target cell lines that through human leukocyte antigen (HLA) class I molecules present relevant levels of peptides from tumor-associated antigens for cytotoxic T lymphocyte (CTL) recognition. METHODS We sequenced the HLA-A and HLA-B loci of eight commonly...

Four new meroterpenoids, guignardones P-S (1-4), and three known analogues (5-7) were isolated from the endophytic fungal strain Guignardia mangiferae A348. Their structures were elucidated on the basis of spectroscopic analysis and single crystal X-ray diffraction. All the isolated compounds were evaluated for their inhibitory effects on SF-268, MCF-7, and NCI-H460 human cancer cell lines. Com...

A series of Adriamycin-resistant human breast MCF-7 and human colon DLD-1 cancer cell lines were established by stepwise selection. The concentration of Adriamycin required to inhibit cell proliferation by 50% (IC50) in the parent breast line (MCF-7), Adriamycin-resistant lines (MCF-Ad5 and MCF-Ad10), and a 5-fluorouracil (5-FU)-revertant line (MCF-R) was 0.005, 3.3, 6, and 4.9 microM, respecti...
