synthesis and dna interaction studies of new cobalt (ii) complexes containing different dinitrogen aaromatic ligands with calf thymus dna using different spectroscopy methods
در این مطالعه بر هم کنش این چهار کمپلکس با dna تیموس گوساله توسط روش های اسپکتروفتومتری، فلوریمتری، دو رنگ نمائی دورانی، و ویسکوزیمتری بررسی شدند تا اثر استخلاف های متیل بر روی لیگاندهای فنانترولین بررسی گردد.
synthesis and characterization of some new cyclometalated organoplatinum(ii) complexes containing phosphite ligand
در این تحقیق روشی جهت سنتز یک سری از کمپلکس های پلاتین (ii) حاوی لیگاند های دهنده ی فسفری شامل فسفیت و فسفین ارائه شده است. واکنش پیش ماده ی پلاتین (ii)،trans/cis- [ptcl2(sme2)2] ، با 2 اکی مولار از لیگاند p(oph)3در حلال بنزن کمپلکس1، cis-[ptcl2(p(oph)3)2] را تولید می نماید. جهت سنتز کمپلکس سایکلو متال فسفیتی، کمپلکس 1 با 1 اکی والان واکنشگر ptcl2 در حلال زایلن در شرایط رفلاکس زیر گاز آرگون م...
detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Investigation of Differential Absorption of Dna Complexes with Ligands
The investigation of complexes of ethidium bromide (EtBr) and methylene blue (MB) with DNA at 0.02 M Na ionic strength of solution has been carried out. Absorption and differential absorption spectra of EtBr and MB and their complexes with DNA were obtained. The isobestic point was revealed on the absorption and differential absorption spectra of EtBr and its complexes with DNA, while on analog...
متن کاملESR Spectra of Fe-NO Complexes with Some Organic Ligands
E SR has been used in the study of iron(I)-nitrosyl complexes w ith organic ligands in solution. Four types of complexes have been identified on basis of the ESR param eters, namely Fe (NO) L 5, Fe (NO) L 2, Fe (NO)2L 2, and Fe (NO)2L. In the iron-nitrosyl complexes with the organic ligands used, the groups more often involved in the coordination are: —C —N H 2; —C —N H ; — C = 0 ; and —C = S (...
