Some properties of midazolam that are of special interest for its practical use are discussed, such as: the basicity of its imidazole ring nitrogen, which allows water- soluble salts and well-tolerated aqueous injectable solutions to be prepared; its stability to hydrolytic degradation; its rapid ...
Results show that the nitrogen at the 1-position in imidazole is mainly photoconverted to NH 4 + ion by analogy with the equivalent nitrogen atom in pyrrole; the nitrogen at the 3-position is transformed into NO 3 ion. Formation of ammonium ions is faster than formation of nitrate ions in...
The structure of the H2 receptor antagonist consists of three parts: the basic aromatic ring structure, and the four atomic chain and the polar group. Alkaline aromatic heterocyclic and alkaline groups substituted aromatic heterocyclic are necessary to active, imidazole ring as the proton transfer mech...
Polymerizations of styrene with azobisisobutyronitrile initiation or thermal initiation have been performed in the presence of dithiocarbamates with different N-groups, that is, benzyl 4,5-diphenyl-1H-imidazole-1-carbodithioate (2a), benzyl 1H-1,2,4-triazole-1-carbodithioate (2b), benzyl indole...
Using the theoretical methods CBS-APNO, G3, and G3B3, we calculate enthalpies of formation of 26.5, 42.4, 31.9, 63.7, 46.8, 81.0, and 79.0 kcal mol-1 for pyrrole, pyrazole, imidazole, 1,2,3-triazole, 1,2,4-triazole, 1H-tetrazole, and 2H-tetrazole. A correlation is developed ...
TMEDA: structure, bonding and reactivity. The physico-chemical properties of theβ-diketonate diamine Cu(ii) compound with hfa (1,1,1,5,5,5-hexafluoro-2-4-pentanedionate) and TMEDA (N,N,N′,N′ tet... G Bandoli,D Barreca,A Gasparotto,... - 《Physical Chemistry Chemical Physics》 ...
1 Synthesis and crystal structure of ZnGGH-1⋅(DMF-H2O). a, Schematic representation of ZnGGH-1⋅(DMF-H2O) synthesis from glycine–glycine–l-histidine and Zn(OAc)2. The tripeptide is deprotonated at the C-terminal acid and the imidazole side chain. The resulting anion acts as a ...
