Synthesis and antibacterial activities of some Substituted 2-styrylquinolines Quinoline nucleus is present in many biologically active classes of compounds. Some of them are used as antiprotozoic, antibacterial and antifungal drugs [1]. Among the various classes of quinolines, 2-styryl quinolines form an important group having a wide spectrum of biological activities [2 – 8] including HIV integrase inhibition activity [9 - 15]. The general method for the synthesis of these derivatives is via…

In this article, foeniculum vulgare is assayed in vitro for antibacterial activity. They used 27 phytopathogenic bacterial species and 2 myropathogenic bacterial species. A significant antibacterial activity is determined by agar diffusion method and reported that foeniculum vulgare essential oil is useful for natural bacterial to control of bacterial disease of plant and seed mainly in organic agriculture. In day today life people used to smoking, poor diet maintenance…

moves to counteract the change. At equilibrium point, a substantial amount of ester, alcohol, water and carboxylic acid was present in the round bottom flask. So to ensure a reasonable yield of the ester, an excess of the alcohols (2-pentanol, 2-butanol and benzyl alcohol) was used to drive the reaction faster. Acetic acid was used as the limiting reagent. The alcohol was used in excess. The researchers suggest removal of water via azeotropic…

nucleophile and DMF as solvent at 50 oC. These azides (4a-b) were reacted with 1-(prop-2-yn-1-yl)piperidin-4-one (5) by click chemistry using standard protocols of sodium ascorbate and copper sulfate as catalyst and an equimolar ratio of water and t-butanol as solvents to yield 1,2,3-triazole linker contained intermediates (6a-b). In the final step, the intermediates (6a-b) were subjected to aldol condensation with substituted benzaldehydes in the presence of 20% aqueous NaOH solution in ethanol…

1. Pyrimidines are heterocyclic aromatic amines which, together with purines, form nucleotides. Nucleotides are the building blocks of nucleic acids, the basic structural component of DNA and RNA. The pyrimidines in DNA are cytosine and thymine, and in RNA uracil replaces thymine (Bettelheim, Brown, Campbell, Farrell & Torres, 2013). 
DNA and RNA are found in the nuclei of all cells and their job is to transmit the information needed for cellular growth and reproduction (Averill & Eldredge,…

Objectives: In the present study we made an attempt to evaluate the association of Plasminogen Activator Inhibitor-1(PAI-1)4G/5G polymorphism with oxidative stress markers Malondialdehyde (MDA) and High sensitivity C-reactive protein (hs-CRP), fibrinolysis marker PAI-1and lipid profiles. Subject and Methods: Blood was drawn and DNA extracted from 90 subjects (46 cases and 44 controls). The 4G/5G polymorphism of PAI-1 was amplified using specific primers. Amplified products were visualized by…

Introduction Some esters are used as food flavourings, while other esters are used as fragrances. Esters are a functional group in organic chemistry. They are characterized by a carbon bound to three other atoms: a single bond to a carbon, a double bond to an oxygen, and a single bond to an oxygen (Clark, 2004). The single bond oxygen is bonded to another carbon. Esters can be produced through various synthetic routes. Since, esters are produced from mixing carboxylic acids and alcohols, they…

The major bottleneck for lipid extraction from the wet microalgae is the low extraction efficiency, because of the immiscibility of nonpolar organic solvents with water contained in wet microalgae {Yoo, 2012 #31} {Kim, 2013 #118}. Traditional method for lipid extraction from dry biomass uses a co-solvent system, which consist of a non-polar solvent and polar solvent {Halim, 2012 #7} {Kim, 2013 #118}. When the co-solvent system is directly applied to wet microalgal biomass, the microalgal cells…

fracking fluid can be pumped at sixty barrels per minute compared to one hundred barrels per minute with polyacrylamide. The increased pumping rate allows for microfractures to be created in the shale. Other chemicals used in slickwater fracturing are butanol, monobutyl ether, hydrochloric acid and ethylene glycol. Also up to five million gallons of water are used per operation (Hyder and Lerner 2250). By 2010, approximately sixty percent of new oil and natural gas wells use hydraulic…
