Application of 5788-58-9, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.5788-58-9, Name is 4,5-Dibromopyridazin-3(2H)-one, molecular formula is C4H2Br2N2O. In a article£¬once mentioned of 5788-58-9

Synthesis of 4-aryl-5-hydroxy- and 5-aryl-4-hydroxypyridazin-3(2H)-ones and their use in the preparation of 4,5-diarylpyridazin-3(2H)-ones and hitherto unknown isochromeno[3,4-d]pyridazinediones

Easily accessible 2-substituted 4-aryl-5-methoxy- and 2-substituted 5-aryl-4-methoxypyridazin-3(2H)-ones were transformed into the corresponding aryl-hydroxypyridazin-3(2H)-ones by alkaline hydrolysis. The use of these compounds in the synthesis of 2-substituted 4,5-diarylpyridazin-3(2H)-ones with two differently substituted aryl groups was investigated. Two aryl-hydroxypyridazin-3(2H)-ones, 2-(2-benzyl-5-hydroxy-3-oxo-2,3-dihydropyridazin-4-yl)benzaldehyde and 2-(1-benzyl-5-hydroxy-6-oxo-1,6-dihydropyridazin-4-yl)benzaldehyde, were transformed into 2-benzyl-1H-isochromeno[3,4-d]pyridazine-1,6(2H)-dione and 3-benzyl-3H-isochromeno[3,4-d]pyridazine-4,6-dione, respectively, via oxidation of the formyl group with KMnO4 followed by lactonization.

Targeting the Warburg Effect in cancer; Relationships for 2-arylpyridazinones as inhibitors of the key glycolytic enzyme 6-phosphofructo-2-kinase/2,6-bisphosphatase 3 (PFKFB3)

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

One-pot synthesis of [1,2,3]triazole-fused pyrazinopyridazindione tricycles by a ‘click and activate’ approach

Substituted [1,2,3]triazole-fused pyrazinopyridazindione tricycles were synthesized in a four-component, stepwise condensation. The key step in this one-pot process was a thermal [3+2] triazole formation which activated the adjacent position and set the stage for a subsequent tandem nucleophilic aromatic substitution/cyclization sequence.
