detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Synthesis of 5-substituted 2'-deoxyuridine-5'- phosphonate analogues and evaluation of their antiviral activity.
A small series of 5-(hetero)aryl-modified nucleoside phosphonates was synthesized via an 8-step procedure including a Wittig reaction and Suzuki-Miyaura coupling. An unanticipated anomerization during phosphonate deprotection allowed us to isolate both anomers of the 5-substituted 2'-deoxy-uridine phosphonates and assess their antiviral activity against a broad panel of viruses.
متن کاملSynthesis of Furo[3,2-b]pyrrole-5-carboxhydrazides and Their Cu, CO and Ni Complexes
Carboxhydrazides 3 were synthesized by reaction of substituted furo[3,2-b]pyrrole-5-carboxhydrazides 1 with 4-oxo-4H-chromene-2-carboxaldehyde 2 in the presence of 3-methyl-benzenesulfonic acid in ethanol. Carboxhydrazides 3 were used as ligands for synthesis of Cu, Co, and Ni complexes 4.
متن کاملEvaluation and Studies on the Structural Impact of Substituted 4, 5- Dihydroisoxazoles on Their Biological Activities
In present study, a series of isoxazole derivatives synthesized were evaluated for antimicrobial activities by disc diffusion method. Some compounds of the series exhibited promising antibacterial and antifungal activity compared to standard drugs. The minimum inhibitory concentration (MIC’s) was determined against each organism. The compounds were tested for their in-vitro antioxidant activity...
متن کاملSynthesis of substituted [3]dendralenes and their unique cycloaddition reactions.
Dimethylsulfonium methylide mediated olefination of 2-phenylethenylidene phosphonoacetate followed by the Horner-Wadsworth-Emmons reaction with aromatic aldehydes provided access to reactive 1,5-diaryl-2-ethoxycarbonyl [3]dendralenes which in situ underwent Diels-Alder cyclodimerisation leading to highly functionalised cyclohexenes with very high regio- and stereoselectivity.
