abstract in this study, we synthesized a novel template polymer by using methacrylic acid (mma) as functional monomer, ethylene glycol dimethacrylate(egdma) as cross linker, 2,2-azobisisobutyronitrile (aibn) as initiator and olanzapine as targeted molecule in the presence of chloroform and acetonitrile as solvent. the products have been characterized and confirmed by (chn)elemental analysis,...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
الانزاپین یک آنتاگونیست انتخابی مونوآمینرژیک با گرایش شدید به گیرنده های سروتونینی و دوپامین و موسکارینیست. مکانیزم اثر این دارو از طریق مهار گیرنده های دوپامین و سروتونین نوع دو صورت میگیرد که این دارو علاوه بر درمان اسکیزوفرنی در درمان مانیای حاد همراه با اختلال دو قطبی نوع یک استفاده میشود. با توجه به اینکه سطح پلاسمایی اولانزاپین به مقادیر نانو گرم در میلی لیتر میرسد لذا باید از متدی استفاد...
abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
In this work, the solubilities of pharmaceutical cocrystals in solvent/anti-solvent systems were predicted using PC-SAFT in order to increase the efficiency of cocrystal formation processes. Modeling results and experimental data were compared for the cocrystal system nicotinamide/succinic acid (2:1) in the solvent/anti-solvent mixtures ethanol/water, ethanol/acetonitrile and ethanol/ethyl acet...
selectfluor [1-(chloro methyl) -4-flouro -1,4-di azonia bicyclo[2,2,2] octane bis (tetraflouro-borate)] catalyzed the preparation of quinoxaline and 2,3-dihydo pyrazine derivatives through one -pot condensation of 1,2-di amines with 1,2-di carbonyls in solvent and under solvent- free conditions. this catalyst is commercially available, inexpensive, reusable, stable to air and moisture, and rela...
A dielectric continuum theory for the solvation of a polar molecule in a polar, polarizable solvent is tested using computer simulations of formaldehyde in water. Many classes of experiments, for example those which measure solvent-shifted vertical transition energies or electron transfer rates, require an explicit consideration of the solvent electronic polarization. Due to the computational c...
بهینه‌سازی شرایط آزمایش با روش آماری تاگوچی برای تهیه نانو ذرات استرانسیم نیترات به روش حلال- ضدحلال
Strontium nitrate as a strong oxidizing agent in the structure of pyrotechnics reacts with fuel and produces light. Red light produced in the tracers due strontium nitrate is within the structure of pyrotechnics. The factors which may affect the particle size of strontium nitrate have been optimized using Taguchi method. The Functional conditions in experimental include strontium nitrate concen...
