The synthesis of 4-methoxy-, 4-amino-3-chloro-, and 4-amino-1-(2,3- dideoxy-beta-D-glycero-pentofuranosyl)pyridazin-6-one nucleosides, 6, 19 and 20 is described. The synthesis of 3,4-dichloropyridazin-6-one (10) was accomplished in 44% overall yield using bromomaleic anhydride (17) as the starting material. The condensation of the silylated base of 10 with the halogenose 12 in the presence of trimethylsilyl triflate as a catalyst afforded a mixture of 3,4-dichloro-1-(3,5-di-O-p-toluoyl-2-deoxy-beta-D- erythro-pentofuranosyl)pyridazin-6-one (13) in 67% and its alpha-anomer 14 in 12% yield, respectively. A series of 3′-sulfonate esters were prepared to explore the synthesis of 3-chloro-4-hydroxy-1-(3-azido-2,3-dideoxy-beta-D- erythro-pentofuranosyl)pyridazin-6-one (32) via 6,3-anhydronucleoside analogues.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, name: 3,6-Dichloropyridazine, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 141-30-0, Name is 3,6-Dichloropyridazine, molecular formula is C4H2Cl2N2

Pyridazine scaffolds are considered privileged structures pertaining to its novelty, chemical stability, and synthetic feasibility. In our quest towards the development of novel scaffolds for effective vascular endothelial growth 2 (VEGFR-2) inhibition with antiangiogenic activity, four novel series of pyridazines were designed and synthesised. Five of the synthesised compounds; namely (8c, 8f, 15, 18b, and 18c) exhibited potent VEGFR-2 inhibitory potency (>80%); with IC50 values ranging from low micromolar to nanomolar range; namely compounds 8c, 8f, 15, 18c with (1.8 muM, 1.3 muM, 1.4 muM, 107 nM), respectively. Moreover, 3-[4-{(6-oxo-1,6-dihydropyridazin-3-yl)oxy}phenyl]urea derivative (18b) exhibited nanomolar potency towards VEGFR-2 (60.7 nM). In cellular assay, the above compounds showed excellent inhibition of VEGF-stimulated proliferation of human umbilical vein endothelial cells at 10 muM concentration. Finally, an extensive molecular simulation study was performed to investigate the probable interaction with VEGFR-2.

Application of 90766-97-5, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 90766-97-5, Name is 5-Bromo-6-phenylpyridazin-3(2H)-one, molecular formula is C10H7BrN2O. In a Article，once mentioned of 90766-97-5

5-Alkylidenepyridazin-3-ones with four points of diversity (R2, R6, X, Y) have been synthesized and evaluated as platelet aggregation inhibitors. Several derivatives eliciting antiplatelet activity in the low micromolar range (e.g., 14e, 14k, 14p, 14v, IC50 ? 1 mu M) were identified. Structure-activity relationships studies on these compounds revealed the key molecular determinants of this new family of antiplatelet agents: (a) two ester groups in the alkoxy moieties; (b) lipophilic substituents at the N2 position of the pyridazin-3-one. The preliminary results of a pharmacological study aimed at determining the mechanism of action of a set of representative compounds revealed that, unlike other pyridazinones, the documented antiplatelet effect is not a consequence of a PDE-III inhibitory activity.
