Synthesis and Applicationof New Fluorescein Analogues
In this project, new derivatives of fluorescein were synthesized using the reaction of maleic anhydride and saccharin with phenol derivatives in the presence of ZnCl2, and their structures were elucidated by UV, IR, and NMR spectroscopy. Fluorimetry studies showed that, the synthesized compounds can be utilized as fluorescent agents, and their efficiencies were dependent on pH of solution. Acco...
متن کاملsynthesis 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...
New solid phase synthesis of distamycin analogues.
A novel and straightforward solid phase synthesis of distamycin analogues containing benzene units has been developed.
متن کاملCholyllysyl fluroscein and related lysyl fluorescein conjugated bile acid analogues.
There have been attempts to couple bile acids to fluorescein to permit their visualization during studies of physiology and pathophysiology. Although conjugation has been achieved by many, the product differed in many respects from the parent bile acid congener. We describe lysylfluorescein conjugated bile acid analogues (LFCBAA) synthesized in our laboratory as model divalent "unipolar" molecu...
متن کاملNew carbocyclic analogues of netropsin: synthesis and inhibition of topoisomerases.
A series of carbocyclic analogues of netropsin were synthesized and evaluated for their capacity to inhibit human topoisomerases I and II in vitro. The compounds are oligopeptides containing 1,4-di- and 1,2,5-trisubstituted benzene rings and unsubstituted N-terminal NH2 groups. Compounds 4-7 consist of two netropsin-like units linked by aliphatic (tetra- and hexamethylene) chains. In the topois...
متن کاملSynthesis and Biological Evaluation of New (−)‐Englerin Analogues
We report the synthesis and biological evaluation of a series of (-)-englerin A analogues obtained along our previously reported synthetic route based on a stereoselective gold(I) cycloaddition process. This synthetic route is a convenient platform to access analogues with broad structural diversity and has led us to the discovery of unprecedented and easier-to-synthesize derivatives with an un...
