this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
the reaction between ni(ii), co(ii), cr(iii) bitrates, ni(ii) chloride and ambidentate a-keto ylide benzoylmethylenetriphenylphosphine (bppy) resulted in isolation of [ni(bppy)2](no3)2.2h2o, [ni(bppy)2]cl2, [co(bppy)2](no3)2 and [cr(bppy)3](no3)3; 2h2o. the compounds were characterized by elemental analyses and infrared 1hnmr spectroscopy, molar conductivity in solution and molecular weight mea...
several novel mononuclear zn(ii) complexes, [zn(bpy)l2], where bpy=2,2’-bipyridine and l=monoanions of phenylcyanamide (pcyd), 4-methylphenylcyanamide (4-mepcyd), 3,5-dimethylphenylcyanamide(3,5-me2pcyd),4-methoxyphenylcyanamide(4-meopcyd), 3,5-dimeth-oxyphenylcyanamide (3,5-meo2pcyd), 3-chlorophenylcyanamide (3-clpcyd), 2,3-dichlorophenyl-cyanamide (2,3-cl2pcyd), 4-bromophenylcyanamide (4-brpc...
a novel complex of cadmium (ii) [cdl0.5(no3)(h2o)](1), l= n,n-bis (o-hydroxyacetophenone) ethylene diamine, have been synthesized as single crystal and nano size. compound 1 in nano size was obtained under sonochemical irradiation and has been characterized by ir, 1hnmr spectroscopy, x-ray powder diffraction (xrd) and scanning electron microscopy (sem). the gray single crystal of compound 1 has...
پنج کمپلکس جدید،از ترکیب لیگاند dpptبا نمک های کلرید، استات و نیترات از فلزات دو ظرفیتی کادمیم، مس، منگنز وکبالت ، تهیه گردیده وبا اسپکتروسکوپی های جرمی، الکترونی، مادون قرمز،آنالیز عنصری و کریستالوگرافی ایکس- ری مورد بررسی قرار گرفته اند.تحقیقات اسپکتروسکوپی برای تمامی این ترکیبات تک هسته ای ،عدد کوئوردیناسیون شش با ساختار هندسی اکتاهدرال را پیشنهاد میدهد.
a series of transition metal complexes with two thiosemicarbazide schiff bases, 1-(4-dimethylaminobenzyl- idene)thiosemicarbazide (abtsc) and 1-(2-pyridincarboxyl-idene) thiosemicarbazide (tcts) were synthesized with co(ii), ni(ii), zn(ii), cd(ii) and ag(i) salts (chloride and acetate). these complexes were characterized by different methods including proton nuclear magnetic resonance (1hnmr), ...
human serum albumin (hsa) is an abundant, multifunctional and nonglycosylated negatively charged plasma protein. hsa ascribed ligand-binding and transport properties, antioxidant functions and enzymatic activities. in the present study, the interaction and side effects of a new designed anti-cancer compound (1,10-phenanthroline butyl dithiocarbamato palladium(ii) nitrate) on hsa have been inves...
the zinc(ii) complex [zn2(dmdtc)2(μ-dmdtc)2] has been synthesized directly from thiram ligand, containing a disulfide bond {dmdtc = n,n-dimethyldithiocarbamate; thiram = n,n-tetramethylthiuram disulfide}, and characterized by elemental analysis and spectroscopic methods. surprisingly thiram, undergoes a reductive disulfide bond scission upon reaction with zn2+ in methanolic media to give the [z...
major histocompatibility complex (mhc) class ii deficiency is a primary immunodeficiency disease characterized by abnormality of mhc class ii molecules surface expression on peripheral blood lymphocytes and monocytes. clinical manifestations include extreme susceptibility to viral, bacterial, and fungal infections but the immunodeficiency is not as severe as scid (severe combined immunodeficien...
