Increased antitumor efficiency and reduced negative side effects in laboratory mice of 4-thiazolidinone derivatives in complexes with PEG-containing polymeric nanocarrier

Synthesis of new 1, 8-dioxo-octahydroxanthene derivatives containing 4-thiazolidinone moiety containing 4-thiazolidinone moiety

A series of novel 1, 8-dioxo-octahydroxanthene derivatives containing 4-thiazolidinone framework (4a-f) were synthesized through a four-step reaction starting from the reduction of nitro derivatives of 1, 8-dioxo-octahydroxanthenes. The resulting aminoxanthenes converted to thiourea derivatives via their reaction with methyl isothiocyanate. The final products were synthesized through the re...

patterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment

although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...

Synthesis of Some 4-Thiazolidinone Derivatives as Antitubercular Agents

Substituted Schiff's bases 2a-o prepared by the treatment of 2-amino-4-(?-methoxyiminocarbomethoxymethyl)-thiazole 1 with different aromatic aldehydes, on cyclocondensation with mercaptoaceticacid and mercaptopropionicacid in dry benzene furnished desired thiazolidinones of type 3a-o and 4a-j, respectively. The structure of the compounds have been assigned on the basis of elemental analyses and...

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...
