A series of novel bis-thiazolidinone derivatives 3(a-j) have been synthesized by the cyclization thiosemicarbazones 2(a-j) with chloroacetic acid and sodium acetate. The integrated heterocyclic compounds were featured chemical spectroscopic methods such as IR, 1H NMR 13C NMR. All screened for their antimicrobial activity against Gram-positive Gram-negative bacteria Staphylococcus Aureus, Bacill...

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...

Purpose: To delve into the related molecular mechanism of suppressor cytokine signaling 4 (SOCS4) on cervical cancer cell proliferation and migration. Methods: Quantitative real-time polymerase chain reaction western blot assays were employed to examine SOCS4 mRNA or protein expression in four human line (HeLa, SW-732, AV3, CaSki) normal epithelium immortalized (H8) MTT viability applied verify...

The objective of this study was to the synergistic antitumor effect lipophilic bismuth nanoparticles (BisBAL NPs) with antibiotic solution Neo-Poly gramicidin on human cervical tumor cells. BisBAL NPs and cancer cell line (HeLa) determined by MTT viability assay fluorescence microscopy. After a 24-h exposure 0.1× HeLa growth decreased 94%. Fluorescence microscopy confirmed death higher among tr...

doxorubicin is a broad spectrum antibiotic used in the treatment of cancers. its dose dependent cardiotoxicity is the most serious side effect causing withdrawal of drug from hard chemotherapeutic regimen. statins are shown to be cytotoxic in concentrations higher than the effective doses for the treatment of hypercholesterolemia (40 mg/day). co-administration of statins and chemotherapeutic ag...

The aims of this study were to construct a tumor-specific bioluminescent eukaryotic vector driven by the hTERT gene promoter and to establish a stable HeLa cell line expressing a modified firefly luciferase gene. PhTERTp-luc and pGL4.17 (luc2/Neo) were digested with SacI and HindIII, respectively, and the recombinant vector phTERTp-luc-neo was generated by ligating the desired fragments. The ex...

A series of fluorinated tetrahydropyrano[3,2-c]chromenes and dihydropyrano[3,2-b]pyran derivatives have been synthesized and their in vitro cytotoxic activities have been determined in cervical cancer cell line (HeLa), human breast adenocarcinoma cell line (MDA-MB-231 and MCF-7) and human alveolar adenocarcinoma cell line (A549). Compounds 4g, 4k, 4p showed a very potent activity against MDA-MB...

Two new compounds, isostreptazolin (1) and sannaphenol (2), were isolated from the culture broth of Streptomyces sannanensis and their structures elucidated on the basis of 1D and 2D NMR as well as MS, IR and UV spectroscopic data analysis. The cytotoxic activity of 1 and 2 were evaluated. Both compounds were inactive against H460 and HeLa cell lines at 100 mM.

background: a possible mechanism by which hyperthermia enhances tumor immunogenicity is the induction of nkg2d ligands on tumor cells. although the expression of mhc class i chain-related protein a and b (mica/b) has previously been reported in different carcinomas, there is no information about mica/b expression in liposarcomas. objective: to investigate mica/b induction in a human liposarcoma...
