against F. columnare BioMed (IC50 of 9.2 and 3.5 mg/l, resp.). These IC50 results were lower than those obtained for wogonin against F. columnare ALM-00-173 and F. columnare BioMed (28.4 and 5.4 mg/l, resp.). However, based on MIC results, none of the compounds evaluated in this study were as active as wogonin (MIC 0.3 mg/l for each F. columnare isolate). Further modification of the wogonin structure
在我们不断探索发现天然产物和基于天然产物的化合物以控制引起黄channel鱼(Ictalurus punctatus)柱状菌病的细菌Flavobacterium columnare的过程中,我们合成了黄酮和查耳酮类似物,并评估了这些化合物以及使用快速生物测定法,从天然来源中提取黄酮类化合物,以抵抗其对柱状双歧杆菌的两种分离物(ALM-00-173和BioMed)的抗菌活性。黄酮类黄绿素(1a),5,7-二羟基-4'-甲氧基黄酮(11),异鼠李素(26),木犀草素(27)和生物素A(29)和查尔酮衍生物8b对F. columnare具有较强的抗菌活性。基于最小抑制浓度(MIC)的ALM-00-173。黄酮类化合物1a,8、11、13(5,4'-二羟基-7-甲氧基黄酮),26,根据MIC结果,29和29对F. columnare BioMed表现出强大的抗菌活性。24小时50%抑制浓度(IC50)结果表明,27和29种化合物对F
