Bio-active compounds present in West Indian Wood Nettle Laportea aestuans (L.) Chew (Urticaceae), used in ethno medicine as antioxidant and antimicrobial were studied. The aim of this research work was to isolate and characterize the bio-active compounds in the n-hexane fraction of L. aestuans, determine the toxicity and subject it to in-vitro antimicrobial and free radical scavenging activitie...

OBJECTIVE This study investigated the effect of extraction solvents on antioxidant bio-active compounds as well as potential antioxidant and lipid peroxidation inhibition of Phyllanthus acidus (P. acidus) leaf extract in minced pork. METHODS The effect of various solvent systems of water, 25%, 50%, 75% (v/v) ethanol in water and absolute ethanol on the extraction crude yield, total phenolic c...

Traditional biological removal processes are limited by the low solubility of halogenated compounds in aqueous media. A new technology appears very suitable for the remediation of these volatile organic compounds (VOCs). Solid/gas bio-catalysis applied in VOC remediation can transform halogenated compounds directly in the gas phase using dehydrated cells as a bio-catalyst. The hydrolysis of vol...

Pharmaceutical drug discovery is reliant on innovative research and development approaches that uncover novel agents that could service a drug pipeline. Development of novel drugs to combat human disease is largely dependent on the availability of safe and effective drugs, many of which are under development and evaluation—the so-called “drug pipeline”. While the costs involved in novel drug di...

HCV-induced hepatitis is one of the most debilitating diseases. The limited number of anti-HCV drugs and drug-resistance necessitate developing of new scaffolds with different mode of actions. HCV non-structural protein 5B (NS5B) is an attractive target for development of novel inhibitors of HCV replication. In this paper, new N'-arylidene-6-(benzyloxy)-4-oxo-1,4-dihydroquinoline-3-carbohydrazi...

introduction: active packaging is one of the innovations in food packaging industry that would be a respons to the changing needs of consumers and markets. in this technique, materials such as adsorbents oxygen, moisture, carbon dioxide, ethylene and carbon dioxide-releasing flavor compounds, antimicrobials, antioxidants and various aromatic compounds are used. in the last decade, great attenti...
