[ 1 ] - Efficient Synthesis of 5,5-Disubstituted Bis-hydantoins/spirohydantoins and a Tetrakis-analogue: A Drug-like Multi-cyclic Scaffold
An easy method was developed for the efficient preparation of diversely new 5,5-disubstituted N(3),N'(3)-linkaged bis-hydantoins. At first, using the same methods, some ketones and terephthalaldehyde were converted to several hydantoins and a new bis-hydantoin , respectively. Then 1,6-dibromohexane, as a mild reagent, was employed for the alkylation and incorporation of synthesized substrates t...
[ 2 ] - Photochemical, Solvatochromic, Electrochromic and Kinetic Investigation of New Synthesized Bicyclic Aziridines with Chalcone Moieties
Bicyclic aziridines show exclusive photochromic behavior. Here, we summarize the results of optical and electrochemical properties, such as photochemical, solvatochromic, electrochromic andkinetic behavior of bicyclic aziridines linked to chalcone moieties. The photochromic process for conversion of closed photoisomers to open photoisomers for compounds 1-10 followed zero-order kinetics. For co...
[ 3 ] - Synthesis and characterization of some novel linear azo-azomethine compounds based on 1-bromo, 4-4-4-nitrophenylazo phenoxy butane
The reaction of some carbocyclic and heterocyclic Schiff bases with the synthesized 1-bromo, 4-[4-(4-nitrophenylazo) phenoxy] butane and formation of novel linear azo-azomethine compounds in good to excellent yields were investigated. The compounds were fully characterized by UV-Vis, FT-IR, 1H NMR spectroscopic techniques and elemental analysis. Effects of various solvents on their visible abso...
[ 4 ] - Design and synthesis of new symmetrical Schiff bases
A series of symmetric multidentate Schiff base ligands 1–13 based on the N‚N′-4‚4′-ethylenebiphenylbis-3-methoxysalicylideneimine for used to bind various transition metals detection of K, AgI‚ CuII, Sr II Co II and NiII at trace levels in real-world samples has been synthesized purified and their structures was characterized.
[ 5 ] - سنتز کارآمد 1-آریل-1H-تترازول ها در حضور کاتالیزور زیرکونیوم اکسی کلراید و مطالعه شیمی کوانتومی محصولات با استفاده از تئوری تابعیت دانسیته
روشی ساده، کارآمد و تطبیق پذیر برای سنتز 1-آریل-1H-تترازول ها با استفاده از واکنش مابین تری اتیل اورتو فورمات، آمین‌های آروماتیک و سدیم آزید در حضور زیرکونیوم اکسی کلراید به عنوان کاتالیزور ارائه شده است. واکنش در حلال استیک اسید و دمای پایین به خوبی انجام گرفته و منجر به تولید محصولات مورد نظر با بازده عالی می‌شود. در ادامه محاسبات شیمی کوانتومی با استفاده از تئوری تابعیت چگالی روی محصولات سنت...
[ 6 ] - Synthesis Pyrano [2,3-c] Pyrazole-based compounds to induce apoptosis by reducing the expression of anti-apoptotic Bcl-2 protein in human breast cancer MCF-7 cells
Aim: Bcl-2 is a potential target for tumor treatment. The inhibition of the Bcl-2 production is research target of attract in the field of anti-cancer drug development. Recently, the assessment of antitumor activity appeared to be promising for pyrazole derivatives. Therefore, this study was designed to investigate the anti-cancer effects of novel pyrazole derivatives (HN1and HN2.). Material an...
