Abstract
本发明公开了处理表面以提供抗菌表面或微尺寸颗粒将粘附于其上的表面的方法。还公开了用于该方法的水分散性硒化物‑脂质构建体和聚阳离子‑脂质构建体。
Description
技术领域
本发明涉及处理表面以提供有利性质例如抗微生物性质的方法,和用于这种方法的脂质构建体。具体而言,本发明涉及使用硒化物-脂质构建体和多胺-脂质构建体处理表面的方法。
背景技术
正如Gallo等人(2014)的出版物所述,预期在医学中可植入装置的预计增加将导致与这些病例有关的感染数量自然增加。目前对适于预防感染的抗菌表面处理的知识进行了综述。表面处理模式包括最小化细菌粘附、生物膜形成抑制和杀菌作用。
Reid等人的出版物公开了包含硒(Se)化合物的杀生物制剂。硒化合物可以沉积在表面上并与其共价或非共价缔合。提议了大量的硒化合物,包括式RSeX的化合物,其中R是脂族基或酚基,x是保护基。
阳离子脂质主要被开发用于脂质体基因递送,作为基于病毒的基因递送的替代,但也被鉴定为具有杀菌活性。常见的阳离子脂质类别包括N-[1-(2,3-二油酰氧基)丙基]-N,N,N-三甲基氯化铵(DOTMA)和3β[N-(N′,N′-二甲基氨基乙烷)-氨基甲酰基]胆固醇(DC-胆固醇)。至少部分因为脂质体转染效率低,绝大多数基因处理的临床试验已经使用了替代的基因递送手段。阳离子脂质的进一步发展试图提高脂质转染的效率。
Behr等人(1989)和Remy等人(1994)的出版物公开了其中脂质是磷脂酰乙醇胺(DOPES和DPPES)的精胺-脂质缀合物。缀合是通过羧基官能化官能化的L-5-羧基精胺衍生物。该缀合物用于制备压实的包被脂多胺的质粒。包被的质粒用于转染程序。
Byk等人(1989)的出版物公开了被开发用于DNA转移的一系列阳离子脂质之间的结构-活性关系。在这些研究中评估的脂胺中,显示多胺几何形状对转染效率有影响。
Randazzo等人(2009)的出版物公开了在基因转移和杀菌活性的背景下对阳离子脂质的双重功能性的探索。被证实具有这些活性的阳离子脂质包含甾醇部分作为脂质组分。
Kato等人(2003)的出版物公开了一种使用生物相容性锚将非粘附细胞以其它方式粘附到表面的方法。
本发明的一个目的是提供一种使用脂质构建体处理外科敷料和植入物的表面的方法,脂质构建体有效地减少术后感染的发生。本发明的一个目的是提供处理表面以有效促进微尺寸颗粒粘附到该表面的方法。本发明的一个目的是提供用于这些方法的硒和聚阳离子-脂质构建体。这些目的要与至少在选择这样的方法或构建体时提供有用的选择的目的一起阅读。

命名为Mal-(CH2)2CO-CMG(2)-Ad-DOPE和H-CMG(2)-Ad-DOPE的构建体的制备
据Bovin等人(2008)的出版物的方案III,由{[2-(2-叔丁氧基羰基氨基-乙酰氨基)-乙酰基]-甲氧基羰基甲基-氨基}-乙酸N-氧基琥珀酰亚胺酯Boc-Gly2(MCMG1y)制备命名为H-CMG(2)-Ad-DOPE的构建体。根据Bovin等人(2008)的出版物的方案IV的第一步制备命名为Mal-(CH2)2CO-CMG(2)-Ad-DOPE的构建体。简而言之,命名为H-CMG(2)-Ad-DOPE的构建体用5倍过量的3-马来酰亚胺基丙酸氧基苯并三唑酯在i-PrOH-水中处理。在SephadexLH-20(i-PrOH-水,1∶2)上进行凝胶渗透色谱法后,以40%收率分离马来酰亚胺-脂质构建体。
NCSeCH2CO-CMG(2)-Ad-DOPE的制备
通过命名为Mal-(CH2)2CO-CMG(2)-Ad-DOPE马来酰亚胺-脂质构建体和硒代亚硫酸钾(K2Se8O3)[方案A]、硒酚(PhSeH)[方案B]和硒化氢(H2Se)[方案C]之间的加成反应来制备氰基硒化物-脂质构建体的尝试未获成功。事后看来,根据方案A未能获得稳定的硒-本特(seleno-Bunte)盐,至少部分可以通过在Distler(1967)的出版物中公开的它们的硫类似物化学行为来预测。分别根据方案B和方案C在质子介质中尝试的苯基硒化物和硒化氢的Michael加成均产生具有减少的马来酰亚胺双键的产品,与期望的硒基琥珀酰亚胺相反。定量产率的硒基琥珀酰亚胺的形成已经在Numeo等人(1981)的出版物中公开。然而,所公开的无水乙醚的使用与命名为Mal-(CH2)2CO-CMG(2)-Ad-DOPE的聚阴离子马来酰亚胺-脂质构建体的使用是不相容的。
随后发现命名为NCSeCH2CO-CMG(2)-Ad-DOPE的氰基硒化物-脂质构建体可以通过活化的2-硒代氰基乙酸(NC-Se-CH2COOH)成功制备。根据方案D(a)或方案D(b),活化的NC-Se-CH2COOH与脂质构建体H-CMG(2)-Ad-DOPE反应。将制备的构建体在惰性气氛下避光保存。选择硒氰酸钾作为选择的试剂,因为它容易根据方案D(a)或(b)活化为N-羟基琥珀酰亚胺(NHS)酯或根据方案D(c)活化为混合酸酐。根据Klauss(1970)的出版物中公开的方法,由新鲜制备的硒氰酸钾(KSeCN)和溴乙酸钾(BrCH2COOK)的溶液合成硒代氰基乙酸钾(NCSeCH2COOK)。活化前将合成的NCSeCH2COOK在黑暗中储存在真空干燥器的氢氧化钾(KOH)小球上。为了活化,将硒代氰基乙酸钾(156mg,0.77mmol)一次性加入N,N,N′,N′-四甲基-O-(N-琥珀酰亚胺基)六氟磷酸铀(HSTU)(IRIS,德国)(212毫克,0.59毫摩尔)的1毫升DMF的溶液中,同时经由PTFE毛细管鼓泡通过轻微流动的干燥氩气。如此获得的浆料以这种方式搅拌30分钟,在此期间初始固体变成更致密的结晶沉淀物(KPF6)。超声处理反应混合物1至2分钟,并与溶于1mL 20%IPA接着溶于100μL 1N KHCO3中的命名为H-CMG(2)-Ad-DOPE(110mg,0.06mmol)的构建体合并。立即沉淀的粘性固体(推测为NCSeCH2COOSu)通过超声处理滴加30%IPA(约1.6mL)溶解,并将反应混合物在室温下磁力搅拌3小时,保持pH为8.0-8.5(TLC对照:溶剂在真空下蒸发,干燥的残余物用3mL乙腈研磨,超声处理,直至形成细浆,然后转移到Eppendorf管(2×2.2mL)中,离心,固体用纯净的IPA和MeCN连续洗涤4次(每次2mL,短暂超声处理然后离心)。将湿固体溶于3.5mL 30%IPA-水中并冻干至恒重,获得111mg(92%)命名为NCSeCH2CO-CMG(2)-Ad-DOPE的氰基硒化物-脂质构建体,其为红色无定形粉末。Rf~0.5,CHCl3/甲醇/水2∶6∶1(v/v);TLC铝片硅胶60F254(Merck 1.05554)。值得注意的是,质谱并未出现适用于该构建体的表征。只可以检测到无Se碎片的峰。在图1中提供了针对构建体确定的1H NMR谱。
作为功能部分的阳离子
制备聚阳离子脂质构建体9a并作为其三氟乙酸(TFA)盐分离(方案E)。简而言之,根据Geall和Blagbrough(2000)的出版物中公开的方法的修改版本,使用Boc作为保护基,进行多胺精胺[CAS#71-44-3](2)的去对称作用。这将认识到该方法也适用于其他非支化多胺如亚精胺[CAS#124-20-9](1)、四亚乙基五胺[CAS#112-57-2](3)、五亚乙基六胺[CAS#4067-16-7](4)和六亚乙基七胺[4403-32-1](5)的去对称。因此,根据方案E可以获得一系列的聚阳离子脂质构建体。
根据方案E,使用同双功能交联剂二琥珀酰亚胺基己二酸酯将Boc保护的、去对称化的中间体N1,N4,N9-三-叔丁氧基羰基)-1,12-二氨基-4,9-二氮杂十二烷(6)与二酰基甘油磷脂1,2-O-二油酰基-sn-甘油基-3-磷脂酰基乙醇胺[CAS#4004-05-1](DOPE)缀合。应认识到其他二琥珀酰亚胺化合物可以用作同双功能交联剂。这些包括:活化的脂质(7a)酰化N1,N4,N9-三叔丁氧基羰基)-1,12-二氨基-4,9-二氮杂十二烷(6)的末端伯氨基,以提供脂化的、Boc保护的多胺中间体(8a)。再者,将会认识到,根据方案I,其他例如1,2-二硬脂酰基-sn-甘油基-3-磷脂酰乙醇胺[CAS#](DSPE)的二酰基甘油磷脂可代替DOPE。
在方案A的最后一步中,对脂化的多胺中间体(8a)脱保护,并分离出作为其三氟乙酸盐的聚阳离子脂质构建体(9a)。

采用微量肉汤稀释法测定金黄色葡萄球菌、大肠杆菌和铜绿假单胞菌临床分离株对命名为Spm-Ad-DOPE(9a)和NCSeCH2CO-CMG(2)-Ad-DOPE的构建体的易感性。如上所述制备各临床分离株的活性生长培养物以获得具有以下浊度(OD600)的培养物:
.金黄色葡萄球菌 1.371
.大肠杆菌(EscherichiaColi) 1.300
.绿脓假单胞菌 0.906
将每种培养物连续稀释至10-6,并用作接种物。将50μL体积的每种稀释液铺在PCA平板上,并在3℃温育18小时。在无菌96孔板中制备两种构建体精胺(2)和亚硒酸(H2SeO3)中的每一种的两倍稀释系列。将50μl体积的接种物分配到含有50μl体积的连续稀释的构建体精胺(2)或亚硒酸(H2SeO3)的孔中。温和混合后,将板在黑暗中在37℃下温育18小时(200rpm),观察最小抑菌浓度(MIC),通过从各孔中取等份试样确定最小杀菌浓度(MBC)。观察到两种构建体相比其单独的功能部分(精胺或亚硒酸)都是更有效的抑菌剂(表2)或杀菌剂(表3)。
表2.通过肉汤微量稀释测定的最小抑制浓度(MIC)。
表3.通过肉汤微量稀释和电镀测定的最小杀菌浓度(MBC)。
表面处理-微尺寸颗粒(生物来源)粘附
命名为Spm-Ad-DOPE(9a)的构建体的储备溶液以10mg/mL的浓度在甲醇中制备。储备溶液在甲醇中稀释至250μg/mL的浓度并且将25μL稀释的储备溶液分配到多孔微孔板(Corning Inc.)的各个圆底孔中。在用去离子水洗涤孔6次之前使板干燥。对照孔类似地使用单独的甲醇(空白)处理或者如在随附的国际申请PCT/NZ2008/000266[公布号WO 2009/048343])的说明书中描述的那样替换命名为生物素-CGG(2)-Ad-DOPE的构建体。
将红细胞(RBC;O组,直至2周龄)洗涤并以1%填充细胞体积(pcv)的浓度重悬于磷酸盐缓冲盐水(PBS)中。将50μL体积的RBC悬液分配到每个孔中并在室温下温育1小时,然后用PBS洗涤6次。通过以2.5%(w/v)的浓度添加50μL体积的戊二醛的PBS溶液并温育10分钟,然后用水洗涤每个孔并使其干燥,来固定RBC。通过加入50μl体积的去离子水溶解RBC并温育10分钟,然后弃去水并使其干燥来裂解RBC。
对于扫描电子显微镜成像(SEM),从板上切下每个孔的底部,并在成像之前用铂溅射涂覆处理表面。图10中提供了根据所描述的方法和用于可商购的平板(Capture-RTMReady-Id,Capture-RTM Ready-Screen和CT-6;ImmucoRInc.)获得的方法对处理的孔表面以增加的放大率获得的图像。
红细胞粘附到根据所述方法处理的孔表面是清晰可见的。进行研究以确定粘附是否归因于使用单独的命名为Spm-Ad-DOPE(9a)的构建体或聚阳离子精胺(2)。以10mg/mL的浓度在甲醇中制备精胺(2)的储备溶液。精胺储备溶液在甲醇或水中稀释至0.2mg/mL的浓度。将命名为Spm-Ad-DOPE(9a)的构建体、精胺(2)的甲醇溶液或精胺水溶液的200μl体积稀释的储备溶液(大约950μM)加入到微孔板的每个第一孔中。然后进行来自每个第一孔的两倍连续稀释。然后将微孔板在真空下干燥,然后用去离子水洗涤微孔板的每个孔,浸泡并丢弃洗涤水4次。干燥后,将50μL体积的在10mM Tris/0.25M蔗糖(SucT)或PBS中浓度为1%pcv的RBC悬液分配到每个孔中。(在命名为Spm-Ad-DOPE(9a)的构建体以29μM或更高的浓度已被添加的孔中的观察到RBC聚集)。将平板在室温下温育1小时,然后用PBS洗涤孔6次。
干燥后,倒转平板,通过光学显微镜(100×放大倍数)检查孔底部是否存在均匀的单层RBC。在图11中显示了用单独的命名为Spm-Ad-DOPE(9a)或精胺(2)的构建体的溶液处理的孔的显微照片。在用命名为Spm-Ad-DOPE(9a)的构建体在两种缓冲液(SucT或PBS)的任一种中浓度为14-237μM(0.015至0.25mg/mL)处理的孔中观察到均匀的单层细胞。当单独使用精胺(2)时,细胞的任何附着不均匀或不可重复。没有观察到细胞粘附在含有单独的精胺(2)的水中的孔中的表面上。
微尺寸颗粒(非生物来源)粘附
将0.05μl(w/v)溴酚蓝和50μM命名为KODE-spm的构建体在水中的100μL溶液分配并散布在层压尼龙网条的表面上。使网条在室温下干燥1小时,然后在使用人造注射器作为“喷烟器”,被暴露于从吸烟香烟或木质燃烧器释放的微粒(暴露约10分钟)。在通过扫描电子显微镜(SEM)(图12)检查之前,将暴露的网条储存在密封的聚乙烯袋中。
