A series of novel ([1,2,4]triazolo[1,5-b]pyridazin-6- yl)oxyalkylsulfonamides was synthesized and evaluated for the ability to inhibit platelet activating factor (PAF)-induced bronchoconstriction in guinea pigs. The compounds bearing a gem-dialkyl or a cycloalkylidene group at the 2 position of the sulfamoylpropyloxy group in the side chain and a methyl group at the 7 position were found to have potent activity. Among them, 2,2-diethyl-3-(7-methyl[l,2,4]-triazolo[1,5-b]pyridazin-6- yl)oxypropanesulfonamide (13) showed excellent anti-asthmatic activity. Compouds 13 may be of significant value in the treatment of asthma and other respiratory diseases. The structure-activity relationships in this series of compounds are discussed.

Chemistry is traditionally divided into organic and inorganic chemistry. SDS of cas: 932-22-9, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 932-22-9

Abstract: A series of novel monocyclic cis-beta-lactams were prepared from phenoxyacetic acid as ketene source and imines derived from 1-chloro-3,4-dihydronaphthalene-2-carbaldehyde and respective amine using ethyl 4,5-dichloro-6-oxopyridazine-1(6H)-carboxylate (or 2-ethoxy carbonyl DCPN) as a carboxylic acid activator.This is the first time 2-ethoxy carbonyl DCPN has been used as an acid activator in synthesis of beta-lactams. The reaction was entirely diastereoselective leading to the formation cis-beta-lactam derivatives.These newly synthesized cis-beta-lactam were fully characterized by FT-IR, 1H NMR, 13C NMR, HRMS, CHNS and X-ray crystallography study. All this novel compound was also evaluated for their antibacterial and antifungal activities against certain strains of Gram-positive bacteria, Gram-negative bacteria and fungi. These compounds displayed moderate activity against using bacterial and fungal strains. Graphic abstract: [Figure not available: see fulltext.].
