Halophilic archaea are known as the novel producers of natural products and their supernatant metabolites could have cytotoxic effects on cancer cells. In the present study, we screened the anticancer potential of supernatant metabolites from eight native haloarchaeal strains obtained from a culture collection in Iran. Five human cancer cell lines including breast, lung, prostate and also human...

Background: Actinomycetes have significant biosynthetic potential of secondary metabolites and promising resource for drug industry. These secondary metabolitesare diverse in biological, chemical structures and functions and the most prolific source of antimicrobial compounds. Most of these antimicrobial have beenisolated from soil-derived actinomycetes of the genus Streptomyces. The aim of thi...
The present study evaluated the effects of infected culture supernatant of erythrocytes, fractionation of culture supernatant and serum from dogs infected with Babesia gibsoni (B. gibsoni) on the maturation of canine reticulocytes in vitro. The SDS-PAGE demonstrated that significantly broader bands were generated by both the infected culture supernatant of erythrocytes and the serum from dogs c...
The metabolism of the mutagen and carcinogen, 5-nitroacenaphthene, by the 9000 x g supernatant from the livers of Aroclor-pretreated rats was studied. The major primary metabolites were 1-hydroxy-5-nitroacenaphthene and 2-hydroxy-5-nitroacenaphthene. These metabolites were oxidized to 1-oxo-5-nitroacenaphthene and 2-oxo-5-nitroacenaphthene, hydroxylated to cis-1,2-dihydroxy-5-nitroacenaphthene ...
Biocontrol agents and their bioactive metabolites provide one of the best alternatives to decrease the use of chemical pesticides. In light of this, the present investigation reports the biocontrol potential of Streptomyces hydrogenans DH16 and its metabolites towards Alternaria brassicicola, causal agent of black leaf spot and damping off of seedlings of crucifers. In vitro antibiosis of strai...
Lactobacillus casei KC-324 was tested for its ability to inhibit aflatoxin production and mycelial growth of Aspergillus flavus ATCC 15517 in liquid culture. Aflatoxin B1 biosynthesis and mycelial growth were inhibited in both simultaneous culture and individual antagonism assays,suggesting that the inhibitory activity was due to extracellular metabolites produced in cell-free supernatant fluid...
BACKGROUND AND AIMS It has been shown that Faecalibacterium prausnitzii (F. prausnitzii), one of the dominant intestinal bacterial flora, may protect colonic mucosa against the development of inflammation and subsequent inflammatory bowel disease (IBD), with the underlying mechanisms being unclear. METHODS The impacts of F. prausnitzii and its metabolites on IL-23/Th17/IL-17 pathway markers w...
Biocontrol agents are an environmentally friendly alternative to chemical pesticides against phytopathogens. The effectiveness of metabolites produced by Bacillus atrophaeus B5 for controlling anthracnose Colletotrichum gloeosporioides in harvested fruit and the possible action mechanisms have been studied. Avocado treated with reduced 54% incidence nearly 70% lesion than untreated fruit. treat...
The quantification of drug metabolites produced during drug metabolism is a growing concern for the pharmaceutical industry, regulatory agencies such as the US Food and Drug Administration, the European Medicines Agency, and others. As 70% of drugs are known reactive metabolites and have black box warnings, they are a major cause of drug-induced injury and lead to drug attrition in early or lat...
