hyper-igm syndromes are characterized by profound reduction of serum igg, iga, and ige levels with normal or increased concentrations of serum igm. cd40 ligand deficiency is x-linked form of the disease, which results in a lack of immunoglobulin class switching from igm to igg in b cells. in addition to the recurrent infections, a number of patients suffer from neutropenia. there are some evide...

the antidiuretic effect of arginine vasopressin (avp) is mediated by the vasopressin v2 receptor. the docking study of avp as a ligand to v2 receptor helps in identifying important amino acid residues that might be involved in avp binding for predicting the lowest free energy state of the protein complex. whereas previous researchers were not able to detect the exact site of the ligand-receptor...

Macrocyclic heterobinuclear Zn(II)–Cu(II) complexes with phenol based dicompartmental ligands possessing contiguous hexa- and penta-coordination sites were prepared by a stepwise procedure. The ligands include similar N4O2 and dissimilar N(imine)3O2 and N(amine)3O2 coordination sites sharing two phenolic oxygen atoms. The six-coordination site comprises two pyridyl pendant arms on the amine nit...

A novel polyfunctional dipodal ligand, L = N,N'-bis[2-[(2-hydroxy-1-naphthyl)methyleneamino]ethyl]propanediamide (DOTA2HNAP) was developed and characterized through elemental and spectral analyses. The complexation behavior of the ligand was investigated with Co2+, Cu2+, and Zn2+ metal ions by potentiometric and spectrophotometric methods in H2O-D...

Siilver tetrafluoroborate complex of 5.11.17.23-tetra-tert-butyl-25-26,27,28-tetrakis (diphenylphosphinoylmethoxy)calyx[4]arene (L) has been synthesized by reaction of silver tetrafluoroborate and L in dichloromethane at room temperature. The complex formed has a 1:1 metall/ligand ratio. 1H and 31P NMR data support an encapsulated structure of the complex in which silv...

2- Azido N, N-Dimethyl Ethane-1-Amine, well-known as a DMAZ, is considered as a new green liquid fuel and a good alternative to hydrazine fuels because of its high performance while being non-carcinogenic. But no DMAZ energetic complex has been synthesized and reported yet. In this study, a new energetic complex of copper (II) nitrate and DMAZ ligand was synthesized for the purpose of increasin...

The Ni(II) and Zn(II) complexes with phenylpyridylformamidine (PhPyF) ligand, [Ni(PhPyF)Cl2] and [Zn(PhPyF)Cl2], have been prepared and investigated using different chemical techniques such as elemental analysis, molar conductance, FT-IR, UV-vis spectra and magnetic moment. The obtained chemical analysis data showed the formation of 1:1 (metal: ligand) ratio. The square planar and tetrahedral g...
