Ethyl 2-(4-methoxyphenyl)-3-(thiophene-2-carbonyl)cyclopropanecarboxylates 2(a-f) and ethyl 4-aryl-7-oxo-4,5,6,7-tetrahydrobenzo[b]thiophene-5-carboxylates 4(a-f) were synthesized by simple procedure. The synthesized new compounds were screened in vitro for their antimicrobial and antioxidant activities. The compounds 2b and 4f showed excellent antibacterial activity; while 2b and 4f showed rem...

A series of substituted benzofuran derivatives were synthesized and characterized by spectral data. Some of the synthesized compounds were tested for in vitro antioxidant activity. Some of them have shown very good antioxidant activity. These compounds were also tested for antimicrobial activity against microbial strains viz. staphylococcus aureus (NCIM 5021) and salmonella typhimurium (NCIM 25...

Background: Antioxidants are developed to assist the immune system and overcome oxidative stress, the aggression of cellular constituents due to imbalance between reactive oxygen species and the inner antioxidant system. The main objective of this study was to search for new and potent antioxidants to protect humans against diseases associated with oxidative stress. Methods: In this study, thr...

The isolation, structural elucidation, antioxidant effect and antibacterial activity of isoforsythiaside, a novel phenylethanoid glycoside isolated from Forsythia suspensa, were described. The antioxidant activity was estimated using the 1-diphenyl-2-picrylhydrazyl scavenging activity method and the in vitro antimicrobial activity was evaluated by the microtitre plate method. The results showed...

A rapid in vitro method for measuring antioxidant activity is presented, which enables the evaluation of health claims and the optimization of product development with respect to health protecting compounds. Antioxidant activity is assessed in a system in which lipid peroxidation is induced in male rat liver microsomes by ascorbic acid and FeSO(4). This method has been significantly improved by...

xanthine oxidase plays crucial roles in the production of reactive oxygen species (ros), and uric acid in blood which may lead to gout, one of the oldest known forms of arthritis amongst humans. summer savory (satureja hortensis l.) a medicinal/spice exhibits antioxidant activity, but unknown effects on xanthine oxidase activity. here, for the first time, we examined the effects of s. hortensis...

Fruit and leaves of junipers are commonly used internally as tea and pounded fruits are eaten to lower blood glucose levels in Anatolia. Thus, we aimed to evaluate antidiabetic and antioxidant potential and the chemical profile of Juniperus foetidissima Willd. and J. sabina L. in this study. In-vitro antidiabetic activities of leaf and fruit extracts were examined by their inhibitory activity o...

The ethanol extract of Bacopa monnieri Linn. (Schrophulariaceae) aerial parts (EBM) was investigated for any in vitro and in vivo antioxidant and hepatoprotective effects. EBM was prepared and estimation of total phenolics was carried out. Further, the antioxidant activity of EBM was studied using four in vitro models. The amount of total phenolics was estimated to be 47.7 (g of pyr...
