Novel derivatives of puberulic acid were synthesized and their antimalarial properties evaluated in vitro against the Plasmodium falciparum K1 parasite strain, cytotoxicity a human diploid embryonic cell line MRC-5, vivo efficacy using berghei-infected mouse model. From previous information that three hydroxy groups on tropone framework essential for activity, we converted carboxylic moiety int...

Silver/manganese dioxide (Ag@MnO 2 ) nanorods are synthesized and characterized by scanning electron microscopy, transmission energy dispersive X-ray spectroscopy, powder diffraction, photoelectron spectroscopy. It was discovered that Ag@MnO can realize hydrogen-borrowing reactions in high yields also effective for the synthesis of tert-butyl esters from aryl cyanides hydroperoxide a short peri...

Determination of relative volatilities flavour compounds in hydro-alcoholic solutions is usually performed by time-consuming and costly standard methods such as the Gillespie dynamic recirculation method. This study tested a quick easy method with simple distillation apparatus for measuring empirical volatilities. A total 17 representative apple pear brandies were selected investigated their al...

Vitrimer materials, which are permanently cross-linked but reshapable polymers, a class of materials growing interest due to their potential in recycling and sustainable development. More precisely, vitrimers derived from commodity polymers could have drastic impact on plastic consumption the upcoming years. Here, development polystyrene-based vitrimer harnessing recently discovered hemiacetal ...

Anaerobically treated molasses-based distilleries spent wash is a major source of terrestrial and aquatic pollution due to the mixture various unknown organometallic compounds in discharged waste. The nature pollutants present effluent has be characterized prior evaluation their fate environment at tropic levels. absorption maxima (λmax) were obtained 295 nm which indicated that melanoidins are...

Within the depleting resources of fossil fuels and the increase in their price, in the recent past a lot of interest has been given to the use of plant oil specially the non-edible oil and its ester (biodiesel). Although the use of biodiesel in place of diesel has resulted in much lesser tail pipe emission, a substantial increase of NOx is reported by several researchers. It may be due to low c...

Ester compounds are widely used in applications such as solvents, plasticizers, polymers, lubricants, cosmetics, medicinals, agrochemicals, soaps and other surface active agents, to mention a few. In many of these applications the simultaneous knowledge of the phase behavior and interfacial properties is an advantage for designing better products and improved processes. The van der Waals densit...
