ZnCl2 is an efficient catalyst for synthesis of carboxylic acid anhydride from 2-acyl-4,5-dichloropyridazin-3(2H)-ones. Treatment of 2-acyl-4,5-dichloropyridazin-3(2H)-ones with ZnCl2 (0.5 equivalents) and air in refluxing dry THF or acetonitrile gave the corresponding symmetric acid anhydrides in good to excellent yield.

Two organic materials incited by electron deficiency of a pyridazine moiety were designed for application as bipolar host materials of phosphorescent organic light-emitting diodes. Modification of the pyridazine moiety with carbazole and pyrrolocarbazole hole transport units provided 3,6-bis(2-(9H-carbazol-9-yl)phenyl)pyridazine (CzPd) and 3,6-bis(2-(3-phenylpyrrolo[3,2-a]carbazol-10(3H)-yl)phenyl)pyridazine (PCzPd) as bipolar host materials. The 3,6-bis(2-(9H-carbazol-9-yl)phenyl)pyridazine and 3,6-bis(2-(3-phenylpyrrolo[3,2-a]carbazol-10(3H)-yl)phenyl)pyridazine were high triplet energy hosts by ortho- substitution of the hole transport units. Based on the triplet energy of the host materials, green phosphorescent organic light-emitting diodes were devised and the green devices presented high quantum efficiency of 15.5%

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, 35857-89-7, name is 6-Chloropyridazine-3-carbonitrile, introducing its new discovery. COA of Formula: C5H2ClN3

The vicinal proton coupling constants were obtained for some 6-membered ring unsaturated heterocyclic compounds.The R values and ring dihedral angles were determined and found to be consistent with half-chair conformations.Relative to saturated heterocyclic compounds, the effect of the sulfur atom on ring puckering was attenuated.However, an increase in ring puckering resulted from the sulfone group and was attributed to torsional energy.

A novel series of 1,2,4-thiadiazole compounds was discovered as selective S1P1 agonists. The extensive structure-activity relationship studies for these analogues were reported. Among them, 17g was identified to show high in vitro potency with reasonable free unbound fraction in plasma (Fu > 0.5%), good brain penetration (BBR > 0.5), and desirable pharmacokinetic properties in mouse and rat. Oral administration of 1 mg/kg 17g resulted in significant peripheral lymphocytes reduction at 4 h after dose and rapid lymphocytes recovery at 24 h. 17g showed a transient lymphopenia profile in the repeated dose study in mouse. In addition, 17g also demonstrated efficacy comparable to that of FTY720 (1) in the mouse EAE model of MS.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Safety of Methyl 6-chloropyridazine-3-carboxylate, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 65202-50-8, Name is Methyl 6-chloropyridazine-3-carboxylate, molecular formula is C6H5ClN2O2

We report herein the design and synthesis of a series of structural modified dimethylpyridazine compounds as novel hedgehog signaling pathway inhibitors. The bicyclic phthalazine core and 4-methylamino-piperidine moiety of Taladegib were replaced with dimethylpyridazine and different azacycle building blocks, respectively. The in vitro Gli-luciferase assay results demonstrate that the new scaffold still retained potent inhibitory potency. Piperidin-4-amine moiety was found to be the best linker between pharmacophores dimethylpyridazine and fluorine substituted benzoyl group. Furthermore, the optimization of 1-methyl-1H-pyrazol and 4-fluoro-2-(trifluoromethyl)benzamide by different aliphatic or aromatic rings were also investigated and the SAR were described. Several new derivatives were found to show potent Hh signaling inhibitory activity with nanomolar IC50 values. Among these compounds, compound 11c showed the highest inhibitory potency with an IC50 value of 2.33 nM, which was comparable to the lead compound Taladegib. In vivo efficacy of 11c in a ptch+/?p53?/? mouse medulloblastoma allograft model also indicated encouraging results.
