Water infusions of Ligustrum delavayanum and Ligustrum vulgare leaves and eight phenolics isolated therefrom have been assayed in vitro on ofloxacin-induced genotoxicity in the unicellular flagellate Euglena gracilis. The tested compounds luteolin, quercetin, luteolin-7-glucoside, luteolin-7-rutinoside, quercetin-3-rutinoside, apigenin-7-rutinoside, tyrosol and esculetin inhibited the mutagenic...
A series of bichalcophene fluorobenzamidines 5a-e was synthesized from the corresponding mononitriles 4a-e via a direct reaction with lithium bis(trimethylsilyl)amide LiN(TMS)2 followed by de-protection with ethanolic HCl (gas). Bichalcophene fluorobenzonitriles 4a-e were prepared adopting a Stille coupling reaction between the bromo compounds 3a-c and 2-(tri-n-butylstannyl)furan or analogues. ...
Article history: Received on: 04/08/2015 Revised on: 07/09/2015 Accepted on: 24/09/2015 Available online: 12/11/2015 The present study was designed to produce novel hydrazine and evaluate their biological properties including antioxidant, antityrosinase and antimutagenic. 4-allyloxybenzoyl hydrazine (1) reacts with 5-acetyl-1,3-dimethyl barbituric acid (2) and 2-Isonitrosoacetophenone (3) in th...
The antimutagenic activity of the methanolic extract of the fruiting bodies of Ganoderma lucidum (Fr.) P. Krast. occurring in South India was investigated. The activity was assayed by Ames Salmonella mutagenicity test using histidine mutants of Salmonella typhimurium tester strains, TA98, TA100 and TA102. The methanolic extract of the mushroom significantly inhibited (P<0.001) the in vitro sodi...
The antimutagenic properties of soluble instant teas were examined using the bacterial Ames assay. Inhibition of the numbers of revertants induced from a number of known mutagens indicates that aqueous extracts of instant teas have antimutagenic activity and antioxidative properties, and can inhibit nitrosation reactions. Despite a significant reduction in the amounts of major green tea catechi...
For this study one species of Shyrnidae family caught along Persian Gulf in Bandarabbas city. Sphyrna lewini were transferred to the laboratory on spring 2007. The antimutagenic activity of the Methanolic and Chloroforamic extracts of muscle, liver and cartilage of Sphyrna lewini with the Ames test was investigated. The use of antimutagens and anticarcinogens in everyday life is the most effe...
Agaricus blazei Murrill extracts have previously been shown to have anticarcinogenic and antimutagenic properties. These results suggest that antimutagenic activity, besides the modulation of the immune system, might be involved in the anticarcinogenic action of A. blazei. To investigate the possible antimutagenic effect of A. blazei in vivo, we evaluated its effect on clastogenicity induced by...
Background: Essential oils from Elettaria cordamomum (cardamom oil) and Lavandula angustifolia (Lavender oil) are used a lot in food and Drug Industry. Cardamom oil traditionally used as spice in food now is increasingly used as diuretic, sedative and for gastrointestinal disease. Lavender oil, traditionally used as an antiseptic agent, is now widely used as a relaxant, carminative, and sedativ...
The radioprotective effects of carnosic acid (CA), carnosol (COL), and rosmarinic acid (RO) against chromosomal damage induced by gamma-rays, compared with those of L-ascorbic acid (AA) and the S-containing compound dimethyl sulfoxide (DMSO), were determined by use of the micronucleus test for antimutagenic activity, evaluating the reduction in the frequency of micronuclei (MN) in cytokinesis-b...
The marine environment is a rich source of biologically active compounds with pharmacological properties. Marine organisms often produce secondary metabolites with structural features different from those produced by terrestrial ones, and the Phylum Porifera seems to be one of the most productive in this sense. This study was undertaken to provide data on mutagenic and antimutagenic activities ...
