3-nitro-6-amino substituted ?imidazo [1,2-b]pyridazine derivatives (5a?5 l) were synthesized in four steps and characterized by FT-IR, 1H NMR, 13C NMR and HRMS. 3-nitro-6-amino substituted ?imidazo [1,2-b]pyridazine derivatives (5a-l) was evaluated for the acetylcholinesterase (AChE) inhibition and antioxidant activities. In both the studies, 3-nitro-6-amino substituted ?imidazo [1,2-b]pyridazine derivatives (5j-l) were inactive. 3-nitro-6-(piperidin-1-yl)imidazo[1,2-b]pyridazine (5c), substituted with piperidine and 3-nitro-6-(4-phenylpiperazin-1-yl) imidazo[1,2-b] pyridazine (5 h), substituted with 1-phenylpiperazine were the most potent compounds (IC50 <0.05 muM for AChE inhibition activity). Latterly, the most potent compounds 3-nitro-6-(4-phenylpiperazin-1-yl) imidazo[1,2-b] pyridazine (5 h), 3-nitro-6-(piperidin-1-yl)imidazo[1,2-b]pyridazine (5c), and moderately active compounds 3-nitro-6-(pyrrolidin-1-yl)imidazo[1,2-b]pyridazine (5b), 6-morpholino-3-nitroimidazo[1,2-b]pyridazine (5d), 1-(3-nitroimidazo[1,2-b]pyridazin-6-yl)piperidine-4-carbonitrile (5e), 6-(4-ethylpiperazin-1-yl)-3-nitroimidazo [1,2-b]pyridazine (5 g), Tert-butyl 4-(3-nitroimidazo[1,2-b] pyridazin-6-yl) piperazine-1-carboxylate (5i) were selected for in vivo study. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Recommanded Product: 141-30-0. Introducing a new discovery about 141-30-0, Name is 3,6-Dichloropyridazine

This paper describes a modified method of preparation of a number of alpha-aryl-alpha-(pyridazin-3-yl)-acetonitriles via the C-arylation reaction of the corresponding carbanions of phenylacetonitriles using 3-chloropyridazine derivatives. KOH and DMSO were used in the deprotonation process, which made the reaction very simple and safe to perform. Nitriles were obtained in the hydrolysis reaction to the corresponding alpha-aryl-alpha-(pyridazin-3-yl)- acetamide derivatives, which were next subjected to cyclization to afford the final products. A number of new derivatives of 7H,8H-pyrimido[1,6-b]pyridazin-6, 8-dione were synthesized in the cyclocondensation reaction of respective alpha-aryl-alpha-(pyridazin-3-yl)-acetamides with diethyl carbonate in the presence of EtONa. The structure and composition of the new compounds were confirmed by IR, 1H- and 13C- NMR analyses and by elemental C, H and N analysis.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 141-30-0, you can also check out more blogs about141-30-0

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, 10071-38-2, name is 6-Chloro-2-methylpyridazin-3(2H)-one, introducing its new discovery. category: pyridazine

A novel class of phosphodiesterase 10A inhibitors with potent PDE10A inhibitory activity and reduced CYP3A4 inhibition was designed and synthesized starting from 2-[4-({[1-methyl-4-(pyridin-4-yl)-1H-pyrazol-3-yl]oxy}methyl)phenyl]quinoline (1). Replacement of pyridine ring of 1 with N-methyl pyridone ring drastically improved CYP3A4 inhibition, and further optimization of these quinoline analogues identified 1-methyl-5-(1-methyl-3-{[4-(quinolin-2-yl)phenoxy]methyl}-1H-pyrazol-4-yl)pyridin-2(1H)-one (42b), which showed potent PDE10A inhibitory activity and a good CYP3A4 inhibition profile. A PET study with 11C-labeled 42b indicated that 42b exhibited good brain penetration and specifically accumulated in the rodent striatum. Further, oral administration of 42b dose-dependently attenuated phencyclidine-induced hyperlocomotion in mice with an ED50 value of 2.0 mg/kg and improved visual-recognition memory impairment at 0.1 and 0.3 mg/kg in mice novel object recognition test.

In a Article，once mentioned of 88491-61-6

Target-based approaches toward new antimalarial treatments are highly valuable to prevent resistance development. We report several series of pyrazolopyran-based inhibitors targeting the enzyme serine hydroxymethyltransferase (SHMT), designed to improve microsomal metabolic stability and to identify suitable candidates for in vivo efficacy evaluation. The best ligands inhibited Plasmodium falciparum (Pf) and Arabidopsis thaliana (At) SHMT in target assays and PfNF54 strains in cell-based assays with values in the low nanomolar range (3.2-55 nM). A set of carboxylate derivatives demonstrated markedly improved in vitro metabolic stability (t1/2 > 2 h). A selected ligand showed significant in vivo efficacy with 73% of parasitemia reduction in a mouse model. Five new cocrystal structures with PvSHMT were solved at 2.3-2.6 A resolution, revealing a unique water-mediated interaction with Tyr63 at the end of the para-Aminobenzoate channel. They also displayed the high degree of conformational flexibility of the Cys364-loop lining this channel.
