Novel pyridazinone derivatives as butyrylcholinesterase inhibitors

In the current study, forty-four new [3-(2/3/4-methoxyphenyl)-6-oxopyridazin-1(6H)-yl]methyl carbamate derivatives were synthesized and evaluated for their ability to inhibit electric eel acetylcholinesterase (EeAChE) and equine butyrylcholinesterase (eqB

Rhodium(III)-Catalyzed Alkynylation of 4-Arylphthalazin-1(2H)-one Scaffolds via C-H Bond Activation

Selective C–H bond alkynylation toward modular access to material and pharmaceutical molecules is of great desire in modern organic synthesis. Disclosed herein is rhodium(III)-catalyzed selective C–H bond mono-/bialkynylation of 4-aryl phthalazin-1(2H)-one was developed. The silver salt AgSbF6 are demonstrated to play a vital role in promoting the bialkynylation reactions. The present alkynylation strategy is simple, efficient, and features high functional group tolerance and broad substrate scope under an air atmosphere. Additionally, 6-aryl pyridazin-3(2H)-one scaffold is amenable to the selective monoalkynylation and sequential bialkynylation, respectively.

Synthesis of some new 2,6-disubstituted-3(2H)-pyridazinone derivatives and investigation of their analgesic, anti-inflammatory and antimicrobial activities

In this study, 12 new 3(2H)-pyridazinone derivatives carrying 4-substituted phenylpiperazinylethyl moiety on lactam nitrogen were synthesized and their chemical structures were confirmed by 1H-NMR, mass, and elemental analysis. Analgesic and anti-inflammatory activities of the synthesized compounds were evaluated in mice. Among the synthesized compounds, compound 9c showed the best analgesic and anti-inflammatory activities without causing any gastric effect in stomachs of tested animals. In addition, the synthesized compounds were screened for their antibacterial and antifungal activities against some pathogenic strains.
