The aim of this study was to evaluate antiviral activity of chloroformic leaves extracts of three plants: Azadirachta indica, Moringa oleifera and Morus alba against Foot and Mouth disease virus using MTT assay (3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide). Antiviral and cytotoxic activity of each extract was evaluated as cell survival percentage and results were expressed as...
The purpose of this study was to assess the in vitro antimicrobial activity of alkaloid-enriched extracts from Prosopis juliflora (Fabaceae) pods in order to evaluate them as feed additives for ruminants. As only the basic chloroformic extract (BCE), whose main constituents were juliprosopine (juliflorine), prosoflorine and juliprosine, showed Gram-positive antibacterial activity against Microc...
mefloquine (mfq), as a racemic mixture is used for the prophylaxis and treatment of malaria. stereoselective pharmacodynamic and pharmacokinetic differences have been observed for mfq. in the present study, the human blood was spiked with racemic mfq. the concentration of mfq enantiomers in various blood fractions including packed erythrocyte layer, platelet rich plasma and platelet poor plasma...
Occurrence and distribution of methylated purines in the ribonucleic acids of subcellular fractions.
A water-soluble cationic porphyrin, 5,10,15,20-Tetra(N-methylpyridinium-4-yl)-21H,23H-porphyrin has been shown to intercalate selectively into the A3-G4 gap of C-quadruplexed DNA d(TTAGGG)4.
in the present study ethanol and water extracts of 15 seaweeds, dictyota dichotoma var. velutricata, dictyota indica, iyengaria stellata, padina pavonia, sargassum swartzii, sargassum variegatum, stoechospermum marginatum, stokeyia indica, jolyna laminarioides, caulerpa taxifolia, halimeda tuna, ulva fasciata, ulva lactuca, solieria robusta, and melanothamnus afaqhusainii, were evaluated for th...
The electronic spectra of chloroformic acid ClCOOH and formic acid HCOOH are computed in large-scale multireference configuration interaction (MRD-CI) calculations. The computed spectrum of formic acid is in reasonable agreement with prior calculations and experimental data. The first electronic transition of ClCOOH is computed at 6.41 eV (193.4 nm), about 0.5 eV higher than in HCOOH. Together ...
The phytochemicals present in the plants are responsible for the biological activities and therapeutic properties of the various medicinal plants. They function as antioxidants in health promotion by preventing oxidant-damage which is the main cause of many diseases. The present study deals with the comparative analysis of phytochemicals in the methanolic and chloroformic leaf extracts of three...
