Description

羟苯基衍生物和其生物学应用
技术领域
本发明涉及羟苯基衍生物和制备其的方法。本发明还涉及其生物学应用,特别是作为抗细菌和/或抗寄生虫药物的生物学应用。 
本发明更特别地涉及三氯生衍生物。三氯生(TCL)5-氯-2-(2,4-二氯-苯氧基)-苯酚(A)在超过30年中已经在卫生保健领域主要用作抗微生物洗涤产品的广谱杀生物剂,其如式(A)所示: 
背景技术
近来,三氯生已经广泛应用在消费品如牙膏、嗽口水、除臭剂、洗手皂和洗液。其还被加入儿童玩具、砧板、以及用于包裹肉制品的塑料膜中。直到最近,人们仍旧认为小的疏水性分子三氯生通过扩散被吸入细菌细胞壁中,而且三氯生通过无特异性地破坏细胞壁的机制显示其抗菌活性。然而,当分离出抗三氯生的大肠杆菌菌株并且所述抗药性被定位至编码大肠杆菌反式烯酰基-酰基载体蛋白还原酶(ENR)的fabI基因时,发现了三氯生抑制脂肪酸生物合成的迹象。细菌中脂肪酸生物合成对许多含有脂质的成分的生成包括细胞膜的生成是必要的。细菌脂肪酸合酶系统(FASII)利用连同酰基载体蛋白(ACP)-相关底物一起起作用的离散的单功能酶。哺乳动物脂肪酸合酶(FASI)与FASII的不同之处在于脂质生物合成通过单一多功能酶-ACP复合物介导。在原核生物和真核生物脂肪酸生物合成中的差异提供了有吸引力的用于选择性FASII抑制的可能。FabI是烯酰基-ACP还原酶,其催化FASII链延伸过程的最终的和限速的步骤。所述反应包括烯酰基-ACP使用辅因子NAD(P)H作为氢化物来源共轭还原(conjugate reduction)至相应的酰基-ACP。 
随后,已经进行了广泛的生物化学和结构研究以证实三氯生为特异性大肠杆菌FabI抑制剂。已经在革兰氏阳性菌肺炎链球菌(Streptococcus pneumoniae)和枯草杆菌(Bacillus subtilis)中分别发现了两种ENR同种型FabK和FabL。FabK抗三氯生,而FabL可逆地被三氯生抑制。三氯生还直接抑制来自金黄色葡萄球菌(Staphylococcusaureus)、流感嗜血杆菌(Haemophilus influenzae)中的FabI,来自结核分枝杆菌 (Mycobacterium tuberculosis)中的ENR、InhA、以及来自疟原虫——恶性疟原虫(Plasmodium falciparum)中的ENR。 
由于FabI作为三氯生细菌靶标的新发现,已经报道了若干结构上与TCL无关的特异性抑制剂,它们中很少显示抗菌活性。 
三氯生本身的某些类似物已经记载在对三氯生抗FabI的作用方式的单独的化学-酶促研究中。尤其是,已经确定了若干2-对羟基联苯基醚六氯苯酚与2-羟基联苯基甲烷以及5-烷基化、-氟化或者-甲酰化的衍生物的抗菌活性。另一方面,在FabI被TCL有力地抑制的新发现之前,还报道了某些对TCL的二氯苯酚部分的修饰。例如,通过引入吡啶代替苯基环报道了广谱但非特异性抗菌与抗真菌衍生物。 
与在微生物之间显示没有区别的广谱杀生物效果的TCL相反,将仅靶向携带FabI酶的微生物如金黄色葡萄球菌或者大肠杆菌的新的TCL衍生物将成为对其它细菌种类没有抗菌的作用或者具有选择压力的抗菌剂或者杀寄生虫剂。 
发明人已经发现羟苯基衍生物的具有三氯生基本结构的特定的取代导致衍生物意外地显示对相关的病原体、特别是细菌或者寄生虫活性的选择性与窄谱性。 
于是本发明的一个目的是提供能够选择性地抑制携带Fab酶如FabI、FabL、FabK、InhA的细菌生长的新的被取代的羟苯基衍生物。 
本发明的另一个目的是提供用于合成所述衍生物的方法。 
另一个目的是利用所述分子的生物学性质以提供特别是可用于治疗微生物感染的措施即药物组合物与方法。

使用标准方法制备并纯化来自大肠杆菌的蛋白质FabI用于在于原核表达载体中克隆所述基因之后重组蛋白质表达。 
使用以下方法评定FabI酶的生物化学活性。 
试验缓冲液“AB”包含50mM Hepes pH7.5、100μM二硫苏糖醇、0.006%Triton-X100。将以下成分添加在黑色聚苯乙烯Costar板直到最终的体积为55μL:1.5μLDMSO,或溶解在DMSO中的抑制剂以及53.5μL在AB中的FabI/NADH/NAD+混合物。在室温下预温育60分钟之后,通过添加5μL的巴豆酰基-CoA至60μL的最终体积开始反应。于是该反应混合物由40nMFabI(由内部自大肠杆菌制造,C-末端6-组氨 酸标记的)、20μM NADH(Biochemika)、10μM NAD+(Biochemika)、50μM巴豆酰基-CoA(Biochemika)以及规定浓度的化合物组成。通过Fluostar Optima(BMG)在添加巴豆酰基-CoA之后立即测量并在2小时后测量NADH(lex=360nm,lem=520nm)的荧光强度。酶活性与信号减小量成正比例,由此获得抑制百分数。对于IC50测定,在6至10个不同的浓度下试验抑制剂,并使用XLFIT(IDBS)将有关的抑制拟合至经典的langmuir平衡模型。
