Iodination of nucleic acids in organic solvents with iodine monochloride.
Iodine monochloride, labeled with 1z51, iodinated ribonucleic acid and deoxyribonucleic acid dissolved as hexadecyltrimethylammonium salts in anhydrous dimethylformamide or N-ethyl acetamide. In the case of RNA (polyuridylate, polycytidylate, and soluble RNA) 5-iodouridine S/-phosphate, 8-iodoguanosine 5’-phosphate, and 5-iodocytidine 5’-phosphate are found. After 24 hours of reaction, 32% of U...
متن کاملsynthesis of 3-aryl-2h-benzo[b]-1,4-oxazines in [omim]bf4 and reduction of organic compounds in methylimidazolium formate
در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...
15 صفحه اولOrganic co-solvents in aqueous DNA-based asymmetric catalysis.
Water-miscible organic co-solvents can be used in DNA-based catalytic asymmetric reactions at appreciable concentration without a negative effect on enantioselectivity. While the rate of the copper(II) Diels-Alder reaction is affected negatively by the presence of organic co-solvents, the copper(II) catalyzed Michael addition and Friedel-Crafts alkylation reaction are significantly faster. Addi...
متن کاملAqueous iodine equilibria in Mammalian iodination reactions.
Regulatory activity has been demonstrated in two classes of iodinated organic species: thyroid hormones (T(3) and T(4)) and iodinated lipids (ILs), e.g. 6-iodo-5-hydroxy-8,11,14-eicosatrienoic acid. The formation of iodinated biomolecules requires iodide oxidation. In mammals iodide oxidation is one of several peroxidase-mediated reactions that serve to reduce hydrogen peroxide. I(2) is one of ...
متن کاملPhotodegradation of 2-mercaptobenzothiazole and 1,2,3-benzotriazole corrosion inhibitors in aqueous solutions and organic solvents.
The photochemical degradation of 2-mercaptobenzothiazole (MBT) and 1,2,3-benzotriazole (BTA) inhibitors was studied in the present work in aqueous and in organic solutions. The extent of photodegradation was assessed by UV-Vis spectroscopy and the main reaction products were identified by tandem electrospray ionization mass spectrometry (ESI-MS/MS). The analysis of degradation products upon UV ...
