根据上述方法所得到的吡咯酰腙铜配合物配体合成吡咯酰腙铜配合物的方法,取所述吡咯酰腙铜配合物配体1.0mmol用4ml甲醇和2ml四氢呋喃的混合溶液溶解,加入1.0mmol醋酸铜,轻微搅拌溶解,常温下静置一周,出现棕色块状晶体,得到吡咯酰腙铜配合物1。
根据上述方法所得到的吡咯酰腙铜配合物配体合成吡咯酰腙铜配合物的方法,取所述吡咯酰腙铜配合物配体1.0mmol用4ml甲醇和2ml四氢呋喃的混合溶液溶解,加入1.0mmol氯化铜,轻微搅拌溶解,常温下静置一周,出现绿色块状晶体,得到吡咯酰腙铜配合物2。
实施例2:最低抑菌浓度(MIC)测定方法
在用来培养细菌的营养肉汤基培养基(BPY)、培养霉菌的马铃薯培养基(PDA)和培养酵母菌酵母培养基(YPD)中添加浓度梯度从2mg/mL到20mg/mL吡咯酰腙铜配合物1的二甲基亚砜溶液。阳性对照为氨苄青霉素(Amp),硫酸链霉素(Str)和硫酸卡那霉素(Kan),阴性对照制霉菌素(Nys)。分别取0.1mL细菌细胞(106CFU/mL)和真菌细胞或孢子(5×105CFU/mL)的标准悬浮培养液接种到平板上,然后把每个稀释浓度的目标化合物和抗生素对照涂布到接种后的平板上,在37℃恒温培养箱中培养细菌24h,28℃恒温培养箱中培养真菌60h后观察。以肉眼检测,菌株没有增殖的最低浓度和菌株没有明显增殖的最高浓度的平板培养的目标化合物的平均值为目标化合物对该菌株的最低抑菌浓度。
同理对吡咯酰腙铜配合物2进行最低抑菌浓度(MIC)测定,得出吡咯酰腙铜配合物1和吡咯酰腙铜配合物2的最低抑菌浓度,测出的实验表明它们对金黄色葡萄球菌的最低抑菌浓度达到1.50-16.65ug/ml,因此对于金黄色葡萄球菌,这两种吡咯酰腙铜配合物具有很强的杀灭作用。
