Theophylline derivatives with several groups linked at the 7-position were synthesized and their pharmacological activities were studied on guinea pig. Relaxant action in the tracheal muscle was increased in comparison with that of theophylline when the 3(2H)-pyridazinone system was linked to 7-(2-ethyl)-theophylline through the piperazine ring, but decreased when the 7-(2-ethyl)-theophylline was linked to 3(2H)-pyridazinone ring through an amino group.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Quality Control of 4,5-Dichloro-3(2H)-pyridazinone, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 932-22-9, Name is 4,5-Dichloro-3(2H)-pyridazinone, molecular formula is C4H2Cl2N2O

A series of new pyridazin-3(2H)-one derivatives (3 and 4) were evaluated for their in vitro affinity toward both alpha1- and alpha2-adrenoceptors by radioligand receptor binding assays. All target compounds showed good affinities for the alpha1-adrenoceptor, with Ki values in the low nanomolar range. The polymethylene chain constituting the spacer between the furoylpiperazinyl pyridazinone and the arylpiperazine moiety was shown to influence the affinity and selectivity of these compounds. Particularly, a gradual increase in affinity was observed by lengthening the polymethylene chain up to a maximum of seven carbon atoms. In addition, compound 3k, characterized by a very interesting alpha1-AR affinity (1.9 nM), was also shown to be a highly selective alpha1-AR antagonist, the affinity ratio for alpha2- and alpha1-adrenoceptors being 274. To gain insight into the structural features required for alpha1 antagonist activity, the pyridazinone derivatives were submitted to a pharmacophore generation procedure using the program Catalyst. The resulting pharmacophore model showed high correlation and predictive power. It also rationalized the relationships between structural properties and biological data of, and external to, the pyridazinone class.
