Heterocyclic Building Blocks-Pyridazine

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, category: pyridazine, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 18591-82-7, Name is 6-Methylpyridazin-3-amine, molecular formula is C5H7N3

A series of 3-acylaminomethyl-6-(chloro, iodo and methyl)-2-(phenyl, 4?-t-butylphenyl, 4?-cyclohexyl-phenyl, biphenyl-4?-yl, 4?-chlorophenyl and 4?-iodophenyl)imidazo[1,2-b]pyridazines and imidazo[1,2-a]pyridines has been prepared and examined for interaction with central and mitochondrial (peripheral-type) benzodiazepine receptors. The imidazo[1,2-b]pyridazines were generally more selective for the mitochondrial receptors than the corresponding imidazo[1,2-a]pyridines. Of these compounds, 3-acetamidomethyl-2-(biphenyl-4?-yl)-6-chloroimidazo[1,2-b]pyridazine (9) proved to be the most selective in studies of the displacement of [3H]diazepam from peripheral-type and central benzodiazepine receptors (IC50 2-8 nM and 0% displacement at 1000 nM, respectively).

Reference of 20375-65-9, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 20375-65-9, 3-Phenyl-6-chloropyridazine, introducing its new discovery.

Our previous work revealed that two adjacent D-alpha-aminoxy acids could form two homochiral N-O turns, with the backbone folding into an extended helical structure (1.88-helix). Here, we report the conformational studies of linear peptides 3-6, which contain a D,L-alpha-aminoxy acid dimer segment. The NMR and X-ray analysis of 3 showed that it folded into a loop conformation with two heterochiral N-O turns. This loop segment can be used to constrain tetrapeptides 4 and 6 to form a reverse turn structure. 1H NMR dilution studies, DMSO-d6 addition studies, and 2D-NOESY data indicated that tetrapeptides 4 and 6 folded into reverse turn conformations featured by a head-to-tail 16-membered-ring intramolecular hydrogen bond. In contrast, tetrapeptide 5 with L-Ala instead of Gly or D-Ala as the N-terminal amino acid could not form the desired reverse turn structure for steric reasons. Quantum mechanics calculations showed that model pentamide 7, with the same substitution pattern of 4, adopted a novel reverse turn conformation featuring two heterochiral N-O turns (each of an 8-membered ring hydrogen bond), a cross-strand 16-membered ring hydrogen bond, and a 7-membered ring gamma-turn.
