[ 1 ] - Saccharomyces Cerevisiae as a Biocatalyst for Different Carbonyl Group under Green Condition

In this researchsaccharomyces cerevisiae (baker’s yeast) was used as a cheap, readily accessible, selective, efficient, and green bio-catalyst in a chemo selective reduction of carbonyl group to hydroxyl group. In this green procedure three substrates e.g. (3-(3-nitrophenyl)aziridin-2-yl)-1-phenyl-methanone, pyruvate ester, and 2-acetyl-γ-butyrolactone were r...

[ 2 ] - سنتز بیس چالکون های بر پایه 5،´5 متیلن بیس (2-هیدروکسی بنزآلدهید) و بررسی خواص ضد باکتری آنها

سنتز تک ظرفی مشتقات جدید بیس چالکونها از واکنش بیس آلدهید سنتز شده و کتون‌های مختلف در محیط بازی مورد بررسی قرار گرفت. ترکیبات با طیف سنجی IR،1H NMR ،13C NMR و جرمی شناسایی شدند. فعالیت ضد‌باکتری بیس چالکون‌ها در برابر باکتری‌های سودوموناس آئروژینوا، اشیرشیا کولی، باسیلوس سابتیلیس و استافیلوکوکوس اورئوس ارزیابی شد. داده های زیستی نشان دادند که برخی از محصولات ، فعالیت های مطلوبی دارند. زمان واک...

[ 3 ] - Synthesis of Metformin Hydrochloride nanoliposomes: Evaluation of physicochemical characteristics and release kinetics

Metformin hydrochloride, a drug group of biguanides, with significant efficacy in the treatment of diabetes type II, is decomposed before reaching to the stomach and is wasted in great losses. In this study, the nanoliposomes of metformin hydrochloride were prepared with Bingham method. At first, the single factor test is done. Design variables are: lecithin to cholesterol ratio, organic solven...
