Temperature-Dependence of the Amide-I Frequency Map for Peptides and Proteins
Amide-I Frequency map Infrared spectrum Molecular dynamics simulation
2012/4/5
In our recent work [Phys. Chem. Chem. Phys. 11, 9149 (2009)], a molecular-mechanics force field-based amide-I vibration frequency map (MM-map) for peptides and proteins was constructed. In this work, ...
Proposal of an Amide-Directed Carbocupration Mechanism for Copper-Catalyzed meta-Selective C-H Arylation of Acetanilides by Diaryliodonium Salts
C bond activation Carbocupration Copper catalysis Density functional theory Selectivity
2012/4/5
We examined the puzzling mechanism for Cu-catalyzed meta-C-H arylation reaction of anilides by diaryliodonium salts through systematic theoretical analysis. The previously proposed anti-oxy-cupration ...
Spectroscopic studies and Hartree-Fock ab initio calculations of a substituted amide of pyrazine-2-carboxylic acid - C16H18ClN3O
Amides of pyrazine carboxylic acid IR Hartree-Fock ab initio calculations, hyperpolaziability
2010/4/8
A substituted amide of pyrazine-2-carboxylic acid was prepared and the IR spectrum was recorded and analysed. The compound prepared was identified by NMR and mass spectra. The vibrational frequencies ...
Rapid Synthesis of New Poly(amide-imide)s Based on N-(4-Carboxy phenyl) trimellitimide and Hydantoin Derivatives under Microwave Irradiation
Thermally stable polymers icrowave irradiation Poly (amide-imide Hydantoin derivatives
2010/4/9
Six new poly (amide-imide)s (6a-f) were prepared under microwave irradiation by polycondensation reaction of diacid chloride (4) with 6 different derivatives of hydantoins (5a-f) using O-cresol as a m...

2010/4/13
Six new poly(amide-imide)s were synthesized by the polycondensation reaction of 1,3-bis[4,4'-bis(trimellityimido) phenyl]-2-propenone (6) with 3,3'-diamino diphenyl sulfone (7a), 4,4'-diamino diphenyl...
Synthesis of the Amide Derivatives of 3-[1-(3-Pyridazinyl)-5-phenyl-1H-pyrazole-3-yl]propanoic Acids as Potential Analgesic Compounds
Pyridazine pyrazole analgesic writhing
2010/4/8
A series of structurally diverse amide derivatives of 3-[1-(3-pyridazinyl)-5-phenyl-1H-pyrazole-3-yl]propanoic acids were prepared and tested for their in vivo analgesic activity using an acetic acid...
Synthesis of New Antimicrobial Agents; Amide Derivatives of Pyranones and Pyridinones
Pyran-4(1H)-one 4(1H)-pyridinone antibacterial activity antifungal agents
2010/4/21
In this study, 4(1H)-pyridinones with an amide function in Position 2 of the pyridinone ring showed antimicrobial activity. The synthesis and the biological properties of some novel amide derivatives ...
The I.R. Spectra of Interlamellar Kaolinite-Amide Complexes—I. The Complexes of Formamide, N-Methyl-Formamide and Dimethylformamide
I.R. Spectra Interlamellar Kaolinite Amide Complexes N-Methyl-Formamide
2012/2/20
The i.r. spectra of interlamellar kaolinite complexes with formamide, N-methylformamide and dimethylformamide have been examined. The spectra show that the amides hydrogen-bond, through the C=O group ...
