Fan, Lingling published the artcileSynthesis and antifungal activity of imidazo[1,2-b]pyridazine derivatives against phytopathogenic fungi, Safety of 2-Morpholinoethanol, the publication is Bioorganic & Medicinal Chemistry Letters (2020), 30(14), 127139, database is CAplus and MEDLINE.
A series of 3,6-disubstituted imidazo[1,2-b]pyridazine derivatives were synthesized and characterized with spectroscopic analyses. The antifungal activities of these compounds against nine phytopathogenic fungi were evaluated by the mycelium growth rate method. The in vitro antifungal bioassays indicated that most of compounds displayed excellent and broad-spectrum antifungal activities. Especially, compounds 6-chloro-3-phenylimidazo[1,2-b]pyridazine, 6-chloro-3-(2-fluorophenyl)imidazo[1,2-b]pyridazine, 6-chloro-3-(2-chlorophenyl)imidazo[1,2-b]pyridazine, 6-chloro-3-(thiophen-3-yl)imidazo[1,2-b]pyridazine and 6-methoxy-3-phenylimidazo[1,2-b]pyridazine exhibited 1.9-25.5 fold more potent than the com. available fungicide hymexazol against Corn Curvalaria Leaf Spot (CL), Alternaria alternate (AA), Pyricularia oryzae (PO) and Alternaria brassicae (AB) strains. Structure-activity relation anal. showed that the enhanced antifungal activity is significantly affected by the substituents on the benzene ring and pyridazine ring.
