In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 14305-08-9, name is 4,5-Dibromo-2-phenylpyridazin-3(2H)-one, introducing its new discovery. category: pyridazine

Six novel photochromic bisarylpyridazinones containing 2,5-dimethylthiophene or 5-methyl-2-phenylthiazole unit were synthesized, and their photochromic and fluorescence properties were investigated. The bisarylpyridazinones underwent reversible color change upon irradiation with UV or visible light. The effect of solvents on the absorption spectra of the bisarylpyridazinones was investigated. The closed-ring forms of bisarylpyridazinones displayed negative solvatochromism which was attributed to the high dipolar characters of the molecule. The open-ring forms of bisarylpyridazinones showed fluorescence at 400-480 nm upon excitation at 302 nm, and the intensities of emission bands gradually decreased during the ring-closing photoreactions. Among the synthesized bisarylpyridazinones, 4,5-bis(5-methyl-2-phenylthiazol-4-yl)-2-methyl(or 2-phenyl) pyridazin-3(2H)-ones (5O and 6O) displayed rather large absorption and emission spectral change, higher quantum efficiency during the photoreaction compared to others. A high conversion ratio (94%) to the closed form was observed for 5O.

High-throughput screening of a small-molecule library identified a 5-triazolo-2-arylpyridazinone as a novel inhibitor of the important glycolytic enzyme 6-phosphofructo-2-kinase/2,6-bisphosphatase 3 (PFKFB3) Such inhibitors are of interest due to PFKFB3’s control of the important glycolytic pathway used by cancer cells to generate ATP A series of analogues was synthesized to study structure-activity relationships key to enzyme inhibition Changes to the triazolo or pyridazinone rings were not favoured, but limited-size substitutions on the aryl ring provided modest increases in potency against the enzyme Selected analogues and literature-described inhibitors were evaluated for their ability to suppress the glycolytic pathway, as detected by a decrease in lactate production, but none of these compounds demonstrated such suppression at non-cytotoxic concentrations

Discovery of 5-substituted-N-arylpyridazinones as inhibitors of p38 MAP kinase

The synthesis, structure-activity relationship and modeling of a series of 5-substituted-N-aryl pyridazinone based p38alpha inhibitors are described. In comparing the series to the similar N-aryl pyridinone series, it was found that the pyridazinones maintained a weaker interaction to the p38 enzyme, and therefore showed generally weaker binding than the pyridinones.

After exactly 3min the reaction was quenched by addition of water (0.570muL, 31.61mmol, 10.00 equiv), allowed to warm to 20C over 145min, then poured into saturated aqueous NH4Cl solution. The mixture was extracted with CH2Cl2 (¡Á4), and the combined extracts were dried (MgSO4) and concentrated to dryness under reduced pressure. The dark orange residue was purified by column chromatography on silica gel, eluting with 0-30% EtOAc/hexanes, to give 51 (0.229g, 25%) as a yellow oil: 1H NMR (CDCl3): 7.91 (s, 1H), 7.54 (m, 2H), 7.47 (m, 2H), 7.39 (m, 1H), 3.48 (sept, J=6.9Hz, 1H), 1.40 (d, J=7.0Hz, 6H); LRMS (APCI+): m/z [M+H]+ 295.4 (81Br, 80%), 293.4 (79Br, 100%); TLC Rf=0.70 (20% EtOAc/hexanes)., 14305-08-9
