Synthesis of substituted 2-aryl-and 2-hetarylimidazo[4,5-d]pyridazines
Substituted 2-aryl-and 2-hetarylimidazo[4,5-d]pyridazines were synthesized by oxidative cyclization in the presence of sulfur of 4,5-diamino-6-methylpyridazin-3-one with substituted arene(hetarene)carbaldehydes or heterocyclic compounds having an activate
Further studies on 2-arylacetamide pyridazin-3(2H)-ones: Design, synthesis and evaluation of 4,6-disubstituted analogs as formyl peptide receptors (FPRs) agonists
Formyl peptide receptors (FPRs) play an essential role in the regulation of endogenous inflammation and immunity. In the present studies, a large series of pyridazin-3(2H)-one derivatives bearing an arylacetamide chain at position 2 was synthesized and te

Imidazopyridazinones as novel PDE7 inhibitors: SAR and in vivo studies in Parkinson's disease model
The synthesis and structure-activity relationship studies of a series of compounds from imidazopyridazinone scaffold as PDE7 inhibitors are disclosed. Potent analogs such as compounds 7 (31 nM), 8 (27 nM), and 9 (12 nM) were identified. The PDE selectivit
