This work was to isolate and identify the bioactive secondary metabolite which was produced by myxobacterium Stigmatella eracta WXNXJ-B, and to evaluate its antitumor and apoptosis-inducing effects. The results showed that one novel compound (molecular formula C29H25NO3) was isolated, purified by Sephadex LH-20 column chromatography and preparative RP-HPLC, and identified as 5-(6-benzyl-quinoli...

The search for alternative and effective therapies to fight cancer is one of the main goals pharmaceutical industry. Recently, ionic liquids (ILs) have emerged as potential therapeutic agents with antitumor properties. goal this study was synthesize evaluate bioactivity different ILs coupled active ingredient (API) valproate (VPA) an agent. toxicity prepared evaluated by MTT cell metabolic assa...

In previous studies, it has been shown that the granulocyte macrophage-colony stimulating factor (GM-CSF) or interleukin-2 (IL-2) surface modified MB49 bladder cancer stem cells (MCSCs) vaccine could induce a specific antitumor immunity and against bladder cancer in mice model respectively. However, whether combined administration of GM-CSF and IL-2 could produce specific immune responses to ca...

This study aimed to evaluate the effect of various extracts and fractions obtained from Echinodorus grandiflorus leaves on tumor necrosis factor-α release by lipopolysaccharide-stimulated THP-1 cells, as well as to look at the association between bioactivity and phytochemical composition. To this end, a high-performance liquid chromatography with diode-array detection method was developed and v...

background and objectives: helicobacter pylori is the causative agent of peptic ulcer disease and a co-factor in development of gastric malignancies. lps are among toxic substances produced by h. pylori exhibiting low endotoxic activity compared to typical bacterial lps. the aim of this study was to investigate bioactivity of lps produced by different serotypes of helicobacter pylori compared t...

abstractthe purpose of this investigation was to evaluate the antiproliferative and apoptogenic mechanistic studies of methanol extract of anthocephalus cadamba (meac) on dalton’s lymphoma ascites (dla) cells treated mice. determination of antiproliferative activity was performed by using different dla cells (2×106 cells, i.p.) inoculated mice groups (n=12). groups were treated for 14 consecuti...

in view of potential biological activities of small molecule polyamides, we synthesized some novel n-(2-aminoethyl)-1-benzyl-2- (alkylthio)-1h-imidazole-5-carboxamide (7a,b), and n-(2-(1-benzyl-2-(alkylthio) -1h-imidazole- 5-carboxamido) ethyl)-1-benzyl-2- (alkylthio)-1h-imidazole-5-carboxamides (8a,b) as antitumor agents. the antitumor activity of compounds 7a,b and 8a,b was studied at concent...

introduction: glass-ionomer cements (gics) are one of the most important dental restorative biomaterials. the aim of this study was to synthesize glass-ionomer‒silk fiber composite and evaluate the effect of adding natural degummed silk fiber on the bioactivity and the ability to release fluoride by glass-ionomer cement. materials and methods: in this study, commercial fuji ii glass-ionomer cem...

objective: methanol extract of bran and unpolished grain of two traditional aromatic rice genotypes viz. kalijira and chinigura were assayed for their activity on the growth and initiation of crown-gall tumors on potato disks. materials and methods: three agrobacterium tumefaciens (a. tumefaciens) strain atsl0105, atta0112, and atac0114 were used as the tumor forming agent. collected rice was s...
