a new group of 4-(imidazolylmethyl) quinoline derivatives possessing a methylsulfonyl cox-2 pharmacophore at the para position of the c-2 phenyl ring were designed and synthesized as selective cox-2 inhibitors and in-vitro anti breast cancer agents. in-vitro cox-1 and cox-2 inhibition studies showed that all the compounds were potent and selective inhibitors of the cox-2 isozyme with ic50 value...
As a continuous research for discovery of new COX-2 inhibitors, chemical synthesis, in vitro biological activity and molecular docking study of anew group of 1,4-dihydropyridine (DHP) derivatives were presented. Novel synthesized compounds possessing a COX-2 SO2Me pharmacophore at the para position of C-4 phenyl ring, different hydrophobic groups (R1) at C-2 position and alkoxycarbonyl groups (...
A new series of peptide-like derivatives containing different aromatic amino acids andpossessing pharmacophores of COX-2 inhibitors as SO2Me or N3 attached to the para positionof an end phenyl ring was synthesized for evaluation as selective cyclooxygenase-2 (COX-2)inhibitors. The synthetic reactions were based on the solid phase peptide synthesis methodusing Wang resin. One of the analogues, i...
Arthritis refers to different medical conditions associated with disorder of the primary structures that determine joint functions such as bones, cartilage and synovial membranes. Drug discovery and delivery to retard the degeneration of joint tissues are challenging. Current treatments of different arthritis involves administration of ideal non-steroidal anti-inflammatory drugs (NSAIDs) but ar...
مهم ترین راهبرد در طراحی ترکیبات ضد التهابی قوی با کاهش قابل توجه اثرات جانبی، بازداری انتخابی آنزیم سیکلواکسیژناز-2 (cox-2) است. در پژوهش حاضر مطالعات qsar با استفاده از توصیف کننده های مولکولی مختلف سعی در کشف ساختار و خواص فیزیکوشیمیایی مشتقات پیرازولین به عنوان بازدارنده های cox-2 را دارد. ساختارهای سه بعدی 23 تا از مشتقات پیرازولین توسط روش نیمه تجربی am1 در نرم افزار hyperchem بهینه شدند....
Background & Objectives: Cox regression model is one of the statistical methods in survival analysis. The use of smoothing techniques in Cox model makes the more accurate estimates for the parameters. Fractional polynomial is one of these techniques in Cox model. The aim of this study was to assess the effects of prognostic factors on survival of patients with gastric cancer using the fractiona...
Abstract Background: Lung cancer is one of the most common cancers around the world. The aim of this study was to use Extended Cox Model (ECM) with Bayesian approach to survey the behavior of potential time-varying prognostic factors of Non-small cell lung cancer. Materials and Methods: Survival status of all 190 patients diagnosed with Non-Small Cell lung cancer referring to hospitals in ...
A group of 1,3-biarylhydrazide derivatives possessing a COX-2 azido pharmacophore at the Para- position of the C-1 phenyl ring in conjunction with a N-3 phenyl or substituted-phenyl ring (4-F,4-Cl,4-OMe) were designed and synthesized based on nucleophilic substitution reaction. A molecular modelling study of these compounds showed that the designed molecules were well bound with the active site...
سندرم تخمدان پلی کیستیک(pcos) اختلال سیستم تولیدمثلی و نارسایی اندوکرینی است که با رشد سریع اولیه ی فولیکولی و عدم انتخاب یک فولیکول غالب از ذخیره ی افزایش یافته ی فولیکولی، هایپراندروژنیسم، افزایش آنژیوژنز، جریان خون تخمدانی و متعاقبا عدم تخمک گذاری مزمن همراه است. این سندرم همچنین به عنوان یک بیماری التهابی با افزایش سطح سیتوکین ها و نیز افزایش crp سرم معرفی شده است. نظر به اثرات آنژیوژنیک سی...
