摘要:
A series of ethyl 6-alkoxy-7-phenyl-4-hydroxy-3-quinolinecarboxylates were designed and synthesized. Their structures were confirmed by (1)H NMR, (13)C NMR, IR and HRMS. The biological activities were primarily evaluated against Eimeria tenella according to Anticoccidial Index (ACI) method in vivo. The results showed that compounds 5e, 5f and 5I exhibited anticoccidial activities against E. tenella at 27 mg kg(-1). (C) 2009 Yu Liang Wang.
