nano-cus powders were synthesized with chemical solution method. xrd and sem and spectrophotometry were used for characterization of the cus powders. xrd analysis indicated that tetragonal cus was the main phase with particle size of 16.2nm and little cu2s phase was present. scanning electron microscopy (sem) analysis revealed that powder was plate like and had very little aspect ratio in morph...

Meysam Yarie was born in 1987 in Malayer, Hamedan, Iran. He received his B.Sc. in Applied Chemistry (2010) from Malek-Ashtar University of Technology and M.Sc. in Organic Chemistry (2012) from Kurdistan University under the supervision of Dr. Kamal Amani.

In the present study, a series of 2-substituted-pyridines were synthesized and characterized by IR, (1)H-NMR and Elemental Analysis. The compounds were assayed against seizures induced by maximal electro shock (MES) and pentylenetetrazole (scMet). Neurologic deficit was evaluated by the rotarod test. The decrease in the elevated motor activity by introceptive chemical stimuli (amphetamine antag...

dacarbazine is an antitumor prodrug which is used for the treatment of malignant metastatic melanoma and hodgkin’s disease. it requires initial activation in liver through an n-demethylationreaction. the active metabolite prevents the progress of disease via alkylation of guanine bases in dna strands. in order to investigate the importance of imidazole ring and its dynamictautomerization in ant...

The stereochemistry and mechanisms of hydrogen-transfer reactions catalyzed by the Pseudomonas aeruginosa pyridine nucleotide transhydrogenase have been investigated. In the presence of specific tritimn-labeled pyridine nucleotides, the Pseudomonas transhydrogenase is able to catalyse a direct hydrogen transfer between the reduced and the oxidized pyridine nucleotides. The reduction of DPNf inv...

A bispyridylamine-based hanging unit within the ligand framework of a newly synthesized iron porphyrin complex (Py2XPFe) can act, on one hand, as hydrogen bonding site to facilitate proton transfer in catalysis and, other coordination for second Lewis acidic metal center. The bispyridylamine group close proximity center is able mediate electrocatalytic CO2 reduction anhydrous MeCN. interactions...

Catalytic oxidation of styrene has attracted extensive attention in industries and academia. Benzaldehyde, one the derived valuable aromatic aldehyde products, been extensively applied perfume, pharmacy, dye industries. However, it is difficult to achieve a high yield by transforming into benzaldehyde with sustainable supply active catalysts. Furthermore, conventional catalyst species inevitabl...

Vahid Khakyzadeh was born in Hamedan, Iran. He received his B.S. degree (Pure Chemistry) and M.S. degree (Organic Chemistry) from Bu-Ali Sina University, Hamedan, Iran, at 2008, 2010 respectively under supervision of professor Mohammad Ali Zolfigol. He is currently working on his Ph. D. under the supervision of professor Mohammad Ali Zolfigol in organic chemistry. Among his recent awards, Vahid...

Nicotinamide mononucleotide (NMN) deamidase is one of the key enzymes of the bacterial pyridine nucleotide cycle (PNC). It catalyzes the conversion of NMN to nicotinic acid mononucleotide, which is later converted to NAD(+) by entering the Preiss-Handler pathway. However, very few biochemical data are available regarding this enzyme. This paper represents the first complete molecular characteri...
