One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Recommanded Product: 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

Anomeric O-hetarylation of tetra-O-benzyl- and tetra-O-acetylglucose (1a, b) can be directly performed with electrondeficient heteroaromatic/heterocyclic systems 2-14, which contain imide halide moieties. The reactions were carried out in the presence of a base and led, through an exchange of the halide by the glucopyranosyloxy moiety, to the products 2a-14a, 7b-14b. Predominantly or exclusively beta-products were obtained. Systems bearing more than one imide halide moiety, such as cyanuric fluoride (15) or 5-chloro-2,4,6-trifluoropyrimidine (16), can be employed for successive anomeric O-hetarylations. Investigation of the glycosyl donor properties of O-glucosyl heteroaromatic imidates with 6-O-and 4-O-unprotected glucose derivatives 18 and 19 as acceptors and comparison of the results obtained with data for the corresponding beta-trichloroacetimidates 17abeta and 17bbeta, reveals that 2,3,5,6-tetrafluoropyridin-4-yl glucopyranosides 14abeta and 14bbeta exhibit similar properties. For specific tasks, for instance alpha-glucopyranoside formation, 14abeta may even be advantageous.

In this study new 6-substituted-3(2H)-pyridazinone-2-acetyl-2-(p-substituted benzal)hydrazone V derivatives were synthesized as analgesic and anti-inflammatory agents. The structures of compounds were elucidated by spectral and elemental analysis. Compounds Va, Vb and Vc were exhibited more potent analgesic activity than ASA. Also these derivatives demonstrated anti-inflammatory activity as well as standard compound indomethacin. Side effects of the compounds were examined on gastric mucosa. None of the compounds showed gastric ulcerogenic effect compared with reference nonsteroidal anti-inflammatory drugs (NSAIDs). On the basis of available data, the structure-activity relationship of V derivatives was also discussed.

A number of isosteres (oxadiazoles, thiadiazoles, tetrazoles and diazines) of benzocaine were prepared and evaluated for their capacity to induce methemoglobinemia – with a view to their possible application as humane pest control agents. It was found that an optimal lipophilicity for the formation of methemoglobin (metHb) in vitro existed within each series, with 1,2,4-oxadiazole 3 (metHb% = 61.0 ± 3.6) and 1,3,4-oxadiazole 10 (metHb% = 52.4 ± 0.9) demonstrating the greatest activity. Of the 5 candidates (compounds 3, 10, 11, 13 and 23) evaluated in vivo, failure to induce a lethal end-point at doses of 120 mg/kg was observed in all cases. Inadequate metabolic stability, particularly towards hepatic enzymes such as the CYPs, was postulated as one reason for their failure.
