Computer-aided drug discovery/design methods have played a major role in the development of therapeutically important small molecules for over three decades. These methods are broadly classified as either structure-based or ligand-based methods. Structure-based methods are in principle analogous to high-throughput screening in that both target and ligand structure information is imperative. Str...
abstract the present study investigated the effects of task types and involvement load hypothesis on incidental learning of 10 target words (tws) in junior high schools (jhss) in givi, ardabil. the tasks deployed in this study were two input-based tasks (reading plus dictionary use with an involvement index of 3, and reading plus gap-fill task with an involvement index of 2), and one output-ba...
هدف از این مطالعه طراحی یک روش کلی برای سنتز یک سری از کمپلکس های دو هسته ای متقارن سیکلومتاله شده پلاتین (ii) بوده که دارای یک لیگاند پل زن(1,2-bis[bis(pentafluoro-phenyl)phosphino]ethane),dfppe, است. از واکنش cis-[pt(r)2(sme2)2]، که در آنr= para-tolyl ، با یک اکی والان از لیگاند benzo[h]quinoline,bhq، در استون محصول [pt(r)(bhq)(sme2)] که در آن r= para-tolyl بدست می آید. همچنین از واکنش 5/0 اک...
پروتئینها فراوان تری مولکولهای آلی در بدن جانداران می باشند. آنزیم ها یکی از مهمترین نوع پروتئینهای کروی می باشند که بعضی از فعالیتهای حیات بدانها وابسته است . لیزوزیم اولین آنزیم شناخته شده است . این آنزیم دارای 129 واحد اسید آمینه در زنجیر پلی پپتیدی و چهار پیوند سیستئین درون زنجیری می باشد. لیزوزیم به دلیل دارا بودن اسید آمینه های باردار توان پذیرش بعضی از لیگاندها را دارا می باشد. در این پا...
A liquid membrane containing diethylene glycol monobutyl ether (2) shows specificity for K ion in transport while diethylene glycol dibutyl ether (1) was selective for Na over K . As an extractant, ligand 2 exhibited pronounced extraction selectivity for K over Na in comparison with ligand 1
the present study is paid to the evaluation of the welfare program of the unemployment insurance in iran. the main purpose which was the main reason for performing this thesis, was the unemployment insurance plan’s challenges in iran such as financial problems of this plan, prolongation of the credit receipt for some insured people, unemployment slow exiting from the unemployment insurance fund...
some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...
phosphoryl containing ligand tri-n-octylphosphine oxide (topo) in dichloromethane has been used as an extracting agent for tetravalent thorium and trivalent europium ions from their 1 m sodium nitrates. the equilibrium data reveal that both ions are extracted as the complexes at 1:3 metal/ligand ratio. the values of conditional extraction equilibrium constant (kex) show the superior extractive ...
A ligand-promoted, palladium-catalyzed transfer hydrogenation of terminal alkynes using ethanol as the hydrogen donor is developed. The chemical selectivity control achieved based on ligand regulation. use triethanolamine and tetrahydrofuran at 80 °C under N 2 found to be critical for alkynes. general applicability this procedure highlighted by synthesis 27 alkenes in moderate good yields.
UNLABELLED Structure-based virtual screening (SBVS) methods often rely on docking score. The docking score is an over-simplification of the actual ligand-target binding. Its capability to model and predict the actual binding reality is limited. Recently, interaction fingerprinting (IFP) has come and offered us an alternative way to model reality. IFP provides us an alternate way to examine prot...
