实施例2:细胞化合物的外排率
将金黄色葡萄球菌接种于液体培养基中,培养至OD值(600nm)达到0.6,菌液于6000×g下离心5min,并用20mM的羟乙基哌嗪乙硫磺酸缓冲溶液(HEPES,pH7.0)洗涤3次,将细胞再次悬浮于上述HEPES缓冲溶液中,控制细胞浓度在40mg/mL左右,加入被测化合物,化合物浓度为10μg/mL,在37℃下培养5min,取1mL,并用等量的经冰水冷却过的HEPES缓冲溶液稀释,于4℃和16000×g下离心2min,接着用2mL经冰水冷却过的HEPES缓冲溶液洗涤。将所得的细胞悬浮于1mL100mM的甘氨酸-盐酸缓冲溶液中(pH3.0),在室温下激烈搅拌4h,在室温和16000×g下离心5min,取上清用荧光分光光度计进行测定,根据标准曲线计算出被测化合物在细胞中的累积量(ng/mg)。其他条件不变,用加入100μM羰基氰化物间氯苯腙时,所得的累积量作为对照,按下式计算细菌对被测化合物的外排率:
外排率越低,化合物对外排泵的抑制越好,结果见表2。

本发明的上述实施例表明:在合成的胺甲基连接的苯并吡喃酮-噁唑烷酮型化合物中,一部分的抗菌活性高于阳性对照物青霉素G、卡拉霉素或酮康唑。对大鼠的急毒实验表明,化合物2、14、46、63的剂量达到5g/kg(此剂量为药典规定的无毒剂量)时,没有发现大鼠有中毒迹象,因此在正常剂量下,它们作为药物应用是安全的。
