本發(fā)明屬于新藥物化合物領(lǐng)域,特別涉及一種噻唑橙苯乙烯衍生物及其制備方法和在制備抗耐藥菌藥物中的應(yīng)用。
背景技術(shù):
抗生素的廣泛使用(尤其是濫用)已導(dǎo)致細(xì)菌對(duì)抗生素的耐藥性不斷增強(qiáng),例如新型耐藥菌(俗稱“超級(jí)細(xì)菌”)耐甲氧西林金黃色葡萄球菌(MRSA)、多重耐藥金黃色葡萄球菌(MDRSA)和耐萬古霉素腸球菌(VRE)等相繼出現(xiàn),并有流行趨勢(shì)。目前臨床上常用的抗菌藥物對(duì)耐藥性細(xì)菌幾乎無效,導(dǎo)致病人的死亡率逐年增加,因此迫切需要發(fā)展新型抗耐藥菌藥物。目前,一些新型藥物,如惡唑烷酮類、達(dá)托霉素和鏈陽(yáng)性菌素等藥物正在研制和開發(fā)之中。
FtsZ--細(xì)絲溫度敏感蛋白Z(filamentous temperature-sensitive protein Z)是介導(dǎo)耐藥性致病菌(MRSA和VRE)、肺結(jié)核菌(TB)和一般敏感菌等細(xì)菌分裂的關(guān)鍵蛋白。它幾乎存在于所有的細(xì)菌當(dāng)中,在形態(tài)上高度保守、不易變異;當(dāng)活性受到抑制時(shí),細(xì)菌無法完成增殖分裂形成狹長(zhǎng)絲狀結(jié)構(gòu),導(dǎo)致細(xì)菌死亡,是十分理想的抗菌藥物新靶點(diǎn)。近年來,深入的結(jié)構(gòu)與功能研究揭示,由于FtsZ與人類細(xì)胞分裂蛋白(微管蛋白Tubulin)蛋白序列差異明顯,因此有可能設(shè)計(jì)出選擇性作用于細(xì)菌FtsZ而不干擾宿主細(xì)胞的抑制劑。
噻唑橙苯乙烯類衍生物,可與核酸(DNA或RNA)、蛋白質(zhì)或其他大分子結(jié)構(gòu)非共價(jià)相互作用而使一種或幾種熒光性質(zhì)發(fā)生改變,可作為熒光探針用于生物檢測(cè)。但是,基于噻唑橙苯乙烯類衍生物開發(fā)抗耐藥菌藥物仍未見文獻(xiàn)報(bào)道。

1、抗菌藥物和培養(yǎng)基制備:將待測(cè)化合物溶于DMSO配制成濃度為38.4mg/mL的儲(chǔ)備液,過濾除菌備用。配好的MH肉湯培養(yǎng)基高壓蒸汽滅菌30min,冷卻后待用。
2、種板:菌懸液酶標(biāo)儀600nm測(cè)菌濃度,MH肉湯稀釋至濃度相當(dāng)于0.5麥?zhǔn)媳葷峁?含菌量0.5×108個(gè)/mL),向96孔板中每孔加150μL菌液,待用。
3、加藥:96孔板中1列與12列不加藥,為空白對(duì)照。向2列孔中加入3μL藥液,再補(bǔ)充147μL菌液,充分混勻后吸取150μL混合液至3列,再次充分混勻后吸取150μL混合液至4列,重復(fù)至11列時(shí)吸取150μL混合液棄掉,使2孔至11孔藥物濃度分別為384、192、96、48、24、12、6、3、1.5、0.75μg/mL。DMSO為溶劑對(duì)照,甲氧西林為陽(yáng)性對(duì)照。
