Description
技术领域
本发明属于药物化学技术领域,具体涉及一种具有抗耐药菌活性的含噁二唑-吡啶季铵盐侧链截短侧耳素衍生物及其合成方法。
背景技术
目前细菌耐药问题日趋严重,对人类健康造成极大威胁,成为全球关注的热点。细菌耐药性的产生与目前抗菌药的滥用有着重要关联。近年来,耐药细菌越来越多,耐药范围越来越广,程度越来越高,多重耐药菌不断出现,因此探索具有新型抗菌作用机制、良好生物利用度且广谱的抗菌药物具有重要意义。
截短侧耳素是由高等真菌产生的一种二萜类兽用抗生素,对革兰阳性菌和支原体有强抗菌活性。1951年被Kavanagh等首先发现、定义并分离,随后通过化学修饰,获得了活性增强和水溶性提高的新衍生物。其中新型兽用衍生物泰妙菌素和沃尼妙林的成功研发以及人用药物瑞他莫林和来法莫林的成功上市,预示着截短侧耳素衍生物的深入开发具有良好的前景。其发挥抗菌作用的主要结构是化合物中的三环骨架,能够与细菌核糖体50S亚基的肽酰转移酶活性中心(PTC)形成诱导契合效应,导致其亚基发生重排,同时三环核心突出部分能够覆盖核糖体P位点。这种抗菌机制不同于其他抑制蛋白合成的抗生素,从而使得对截短侧耳素的研究已成为国际上的热点。
季铵盐化合物是一类阳离子表面活性剂,具有溶解性好、化学性能稳定、使用方便、低毒高效、广谱抗菌等优点,一般用在医疗消毒杀菌上比较多,而且该类杀菌剂具有较强的细胞穿透性、稳定性好、低毒、杀菌持续性时间长等特点,杀菌效果显著。

具体操作步骤如下:
(1)MHB培养基配制:称取MHB培养基(购于广州环凯微生物科技有限公司)20.0g,加入到1L蒸馏水中,加热煮沸至完全溶解,分装于锥形瓶中,121℃高压灭菌15min,备用。
(2)实验菌株培养至对数生长期:无菌条件下,将复苏后的实验菌株接种到100mLMHB培养基中,置于37℃恒温恒湿培养箱中培养20-22h,备用。
(3)样品液制备:称取待测样品(本发明合成的化合物1-18、中间体Ⅱ、瑞他莫林、泰妙菌素和沃尼妙林)用DMSO溶液溶解,配制成浓度为10.24mg/mL的样品液,阳性对照品(莫西沙星)用DMSO溶液溶解,配制成浓度为5.12mg/mL的样品液。
(4)菌悬液制备:无菌条件下,将培养至对数生长期的实验菌株用MHB培养基校正到0.5麦氏单位浊度标准后按1:200的比例进行稀释,备用。
(5)微量二倍稀释法测定MIC:取无菌96孔板,在第2孔加入10μL莫西沙星样品液,第4-11孔加入10μL DMSO溶液,第3、4孔加入10μL按梯度设置稀释过的样品液,并对药物进行二倍稀释至第10孔,第11孔为溶剂对照。然后每孔加入190μL稀释过的菌悬液,使每孔最终的菌液浓度为5×105CFU/mL,置37℃恒温恒湿箱中培育20-22h。
(6)MIC终点判读:黑色背景下肉眼观察96孔板中所见能完全抑制细菌生长的浓度为该样品对该种细菌的最低抑菌浓度。
表1受试药物的最小抑菌浓度(μg/mL)
由表1可以看出,本发明制备的含噁二唑-吡啶季铵盐侧链的截短侧耳素类衍生物均对革兰氏阳性菌表皮葡萄球菌(ATCC 12228)表现出不同程度的抑制作用。其中,化合物2、14和17的抑制效果最优,MIC分别为1μg/mL、2μg/mL、2μg/mL,远胜于三种已上市的截短侧耳素类抗生素;对于金黄色葡萄球菌(ATCC 25923和ATCC 29213)而言,化合物1-18均有明显的抑制作用,其中,化合物3、6和12对ATCC 25923菌株的抑菌效果与瑞他莫林与沃尼妙林相当,化合物2和17对ATCC 25923菌株的抑菌效果优于三种上市药物,MIC可以达到2μg/mL,同时化合物2对ATCC 29213抑制效果也是所有化合物中最佳的,MIC为4μg/mL。
通过对比化合物1-18与三种上市药物对耐甲氧西林金黄色葡萄球菌的抑制作用,发现化合物2和17的抑菌效果要优于三种上市药物;合成的化合物1-18可以对大肠杆菌和鲍曼不动杆菌产生不同程度的抑制作用,其中化合物2对两种菌株的抑制程度最好,并且化合物2对大肠杆菌的抑菌效果与瑞他莫林相当。
表2受试药物对临床耐药菌的最小抑菌浓度(μg/mL)
由表2可知,代表性化合物2、14、17对临床分离的耐药菌株仍具有较好的抑制作用,且在大部分测试菌株上都优于对照药物瑞他莫林,此外,化合物2还展现出了广谱的抗菌性能。综上,本发明中含噁二唑-吡啶季铵盐侧链的截短侧耳素类衍生物可以对不同的菌株产生抑制作用,对临床分离的耐药菌也有较好的抑制效果,值得进一步研究。
3.体外细胞毒性测定
采用MTT法评估含噁二唑-吡啶季铵盐侧链的截短侧耳素类衍生物体外细胞毒性。
取处于对数生长期的HepG2、HEK293和A549细胞(均购自于美国ATCC库),胰蛋白酶消化后制成细胞悬液,调整细胞密度约为105个/mL,每孔100μL接种于无菌96孔细胞培养板,置于37℃,5%CO2恒温培养箱中培养24h。待细胞贴满孔板底部后,分别在每孔中加入浓度梯度的药液(瑞他莫林、泰妙菌素、沃尼妙林、本发明合成的化合物2、14和17)10μL,平行设6个复孔,同时设置调零组(不含细胞和药物组)和对照组(不含药物组)。置于37℃,5%CO2恒温培养箱内孵育24h后,每孔加入5g/L MTT溶液20μL继续培养4h。培养结束后,轻轻吸去孔内培养液,每孔加入DMSO 150μL,置摇床上低速振荡10min,使结晶物充分溶解后,于酶联免疫检测仪OD490nm处测量各孔的吸光值,计算细胞存活率,并在光学显微镜下观察细胞的形态变化。根据半数抑制浓度(IC50)来评价药物对HepG2、HEK293和A549细胞的细胞毒性。
表3受试药物的半数抑制浓度(IC50,μM)
表3显示了不同试验药物的半数抑制浓度(IC50),其中化合物2的毒性最小,对HepG2、HEK293和A549细胞的IC50值均大于200.00μM,显著高于瑞他莫林、沃尼妙林和泰妙菌素。细胞形态观察发现,经不同浓度的化合物2处理的HepG2、HEK293和A549细胞,细胞形态正常,折光率高,结构清晰,进一步说明化合物2对三种细胞的毒性较小。化合物14对HepG2和A549细胞的IC50值均大于200.00μM;对HEK293细胞的IC50值为178.00μM,是沃尼妙林(IC50=31.10μM)的5倍。化合物17对HepG2和HEK293细胞的IC50值均大于200μM,显著高于三种上市药物;对A549细胞的IC50值为160.30μM,是沃尼妙林(IC50=46.21μM)的3倍。综上,三种优选化合物2、14和17在细胞毒性方面均优于所测试的三种上市药物,具有较好的安全性。
4.化合物溶解度的测定
实验方法:选取代表性化合物2、13、17测定溶解度,以瑞他莫林的盐酸盐作为对照。分别取各自样品1mg定量溶解于10mL容量瓶中,采取高效液相色谱法测定其吸收峰面积;再将代表性化合物2、13和17及对照药物瑞他莫林的饱和溶剂稀释10倍体积,采用高效液相色谱法测定其吸收峰面积;通过对吸收峰面积的计算获得其各自溶解度。
实验仪器为岛津LC-16,色谱柱为Hypersil C18 ODS(4.6×250mm×5μm),流速为1.0mL/min,检测波长为235nm,流动相为水:乙腈=20:80。

17 | 2.58 | 3.22 | 11.32 |
