Description
发明领域
本发明涉及新的肽及其用途,特别是用于治疗和/或预防感染、炎症、疼痛、伤口、疤痕和/或肿瘤。
发明背景
乳铁蛋白是一种单链金属结合糖蛋白,其分子量为77kDa。已经发现乳铁蛋白的负责杀细菌性能的结构域是被称为乳铁蛋白肽的胃蛋白酶分解的片段(参见例如,BellamyW.,等人,Identificationofthebactericidaldomainoflactoferrin,Biochim.Biophys.Acta1121:130-136,1992,和BellamyW.,等人,AntibacterialspectrumoflactoferricinB,apotentbactericidalpeptidederivedfromtheN-terminalregionofbovinelactoferrin,J.Appl.Bact.73:472-479,1992)。
在许多类型的细胞上发现乳铁蛋白受体,所述细胞包括单核细胞和巨噬细胞、凝集素刺激的人外周血淋巴细胞、刷状缘细胞以及肿瘤细胞株。
几个专利出版物描述了乳铁蛋白在治疗感染或炎症中的可能的用途。在WO98/06425中,例如,公开了乳铁蛋白和乳铁蛋白肽可用于治疗和预防感染、炎症和肿瘤。
EP629347描述了一种抗微生物剂其包含(A)乳铁蛋白水解产物和/或者从乳铁蛋白衍生的一种或多种抗微生物肽,和(B)一种或多种化合物,所述化合物选自金属螯合蛋白、生育酚、环糊精、甘油脂肪酸酯、醇、EDTA或其盐、抗坏血酸或其盐、柠檬酸或其盐、多磷酸或其盐、壳聚糖、半胱氨酸和胆酸作为其有效组分。该抗微生物剂意在用于产品处理,及其特别是用于安全处理例如食品和药品。上述出版物所述试剂因此是一种新的防腐剂。在上述出版物中,给出了多个肽序列并且其中一些肽序列类似于本发明所述的肽,尽管存在多个重要的差异,所述差异进一步描述如下。
US5,304,633公开了从人和牛的乳铁蛋白的水解产物中分离的抗微生物肽。特别公开了对应于人乳铁蛋白的12至47位氨基酸和17至41位氨基酸的肽的分离。

两个氨基酸序列之间的同源性的百分比如下进行确定。首先,将氨基酸序列与例如SEQIDNO:1相比较,使用BLAST2Sequences程序(BI2seq),所述程序来自包含BLASTN的2.0.14版本和BLASTP的2.0.14版本的独立版本BLASTZ。所述独立版本的BLASTZ可从美国政府的国家中心生物技术信息网站ncbi.nlm.nih.gov获得。解释如何使用BI2seq程序的使用说明可以在BLASTZ附带的自述文件中找到。BI2seq使用BLASTP算法来对两个氨基酸序列进行比较。要比较两个氨基酸序列,BI2seq的选项设定如下:-i设置为含有用于比较的第一个氨基酸序列的文件(例如,C:\seq1.txt);-j设置为含有用于比较的第二个氨基酸序列的文件(例如,C:\seq2.txt);-p设置为blastp;-o设置为任何所需的文件名称(例如,C:\output.txt);并且所有其他选项保留为默认设置。例如,下面的命令可以用于生成包含两个氨基酸序列之间比较的输出文件:C:\BI2seq-ic:\seq1.txt-jc:\seq2.txt-pblastp-oc:\output.txt。如果这两个被比较的序列具有同源性,那么指定的输出文件将同源区域呈现为对齐序列。如果两个被比较的序列不具有同源性,那么指定的输出文件将不呈现对齐的序列。一旦对齐,匹配项的数量通过对两个序列中呈现的相同核苷酸或氨基酸残基的位点的数量进行计数决定。
一致性百分比是通过将匹配项的数量除以上述被鉴别序列的序列长度然后将上述结果乘以100来决定的。例如,如果一个序列相比于SEQIDNO:1所示序列(SEQIDNO:1所示序列的长度是18)并且匹配项的数目为16,那么所述序列对于SEQIDNO:1所示序列具有89%一致性百分比(即16÷18*100=89)。
此外,根据本发明所述的肽融合到其他多肽例如谷胱甘肽-S-转移酶、蛋白质A、寡聚组氨酸标签,用以简单化纯化,或融合到被抗体识别的表位例如Myc标签表位,也涵盖在本发明。
本发明也包括含有其他所需特征的融合,所述的特征例如有助于检测或分离肽,或者促进肽的细胞摄取。这些融合伴侣的实例为生物素部分、链霉亲和素部分、放射性部分、荧光部分像小荧光团或绿色荧光蛋白GFP荧光团、免疫原性的标签、能促进细胞摄取肽的亲脂性分子或多肽结构域。
根据本发明所述肽的功能等效变体还可以包括化学修饰或衍生的氨基酸,例如由聚乙二醇化、酰胺化、酯化、酰化、乙酰化和/或烷基化反应。
存在着附加PEG的不同策略,并应包括在内。例如,PEG可以连接到N-末端的氨基上,或者直接或通过使用γ-氨基丁酸作为连接子连接到具有反应活性的氨基或羟基的氨基酸残基(Lys、His、Ser、Thr和Tyr)。PEG还可以偶联到羧基(Asp、Glu、C-终端)或巯基(Cys)。
根据本发明所述肽的功能等效变体还可以包括通过与功能侧链的反应产生的氨基酸的化学衍生物。这种衍生分子包括其中自由氨基已衍生形成胺盐酸盐、对甲苯磺酰基、羧基苯甲酰氧基、叔丁氧羰基、氯乙酰基或甲酰基的分子。自由羧基可衍生形成盐、甲基和乙基酯或其他类型的酯类和酰肼。自由羟基可衍生形成O-酰基或O-烷基衍生物。
根据本发明所述肽的功能等效变体还可以包括所述肽的类肽变体。类肽是模仿肽的构象和特定特征的化合物。例如,类肽包括具有反向(-CO-NH-)连接的肽。此外,类肽包括氨基酸残基通过γ(CH2NH)-键连接来取代常规的酰胺连接的变体。而且,类肽也包括欧米茄-氨基酸,其中的氨基和羧基被不同长度的多聚亚甲基单元分隔。
根据本发明所述肽可以包括修饰,例如酰胺化、氨基末端酰化(例如乙酰化或巯基乙酸酰胺)、末端羟基酰胺化(例如与氨或甲胺),以及肽的N-或C-末端区域被封闭以帮助降低外源蛋白水解消化的易感性的其他末端修饰。进一步,通过的N-末端的乙酰化和C-末端的酰胺化,将肽在末端去电荷。假设受体结合LF的相应序列(其中没有N-和C-末端电荷),加帽的肽应该结合得更好,因为加帽的肽比未加帽的肽在这方面更类似于天然蛋白质。
根据本发明所述肽可以C-末端加色氨酸标签以增加效力,正如Pasupuleti等人BiochimBiophysActa2009,1790:800-8所描述。

实施例
实施例1.肽筛选1
乳铁蛋白衍生的两个类型的肽已经过设计和检测。全部类型中的有活性的肽已被鉴定。
新的肽的变体是基于具有与SEQIDNO:1相似序列的肽的已测量的抗炎和抗微生物活性进行设计。此外,同时注意了上述肽的相应序列的结构方面的考虑。实际上,这意味着保持和增强肽的螺旋性。对于第一轮筛选,类型1的肽的新变体通过引入被建议用来增加螺旋稳定性的N-加帽基序以及(i,i+3)和(i,i+4)亮氨酸间隔来进行设计。进一步,螺旋的两亲性特征通过在特定位点插入极性带电荷氨基酸来进行修饰。来自类型2的肽的新变体是通过增加正电荷和肽的疏水区域来设计的。因而,增加了肽的两亲性特征(图2)。基于新的设计,约50个肽以PEPscreen库(Sigma)的方式排序并检测了其抗炎和抗微生物活性。

实施例2.肽筛选2
上述第一轮筛选的所述肽的TNF-α活性用ProPHECYTM软件(Saromics,隆德,瑞典)进行多元统计分析。对每一个肽计算大量的描述符。然后,TNF-α活性与所述描述符相关联。对每个肽的类别创建分离的回归模型。此外,还创建考量全部肽的类别的整体模型。回归模型的分析提示了对促进TNF-α活性做出贡献的多个变量。对于每一个肽类型推荐的第二轮筛选的新的肽,主要是基于荷电的调节、两亲性以及疏水性。基于新的设计,大约80个肽以PEPscreen库(Sigma)的方式排序并检测了其抗炎和抗微生物活性。

抗炎活性以LPS刺激后THP-1细胞中的对TNF-α生产的抑制作用来测量。
对应人单核细胞的THP-1细胞株(TIB-202;ATCC,马纳萨斯,弗吉尼亚州,美国)维持在RPMI1640(PAALaboratoriesGmbH,Pasching,奥地利),辅以10%胎牛血清(FBS;PAALaboratoriesGmbH,Pasching,奥地利),1mM丙酮酸钠(Sigma-Aldrich,圣路易斯,密苏里州,美国)和20mMHEPES(PAALaboratoriesGmbH,Pasching,奥地利)。

抗微生物的活性以通过使用最小微生物杀伤浓度MMC

测定法对金黄色葡萄球菌
的抗细菌作用进行测量
培养在血液-琼脂板上[哥伦比亚琼脂(Oxoid,贝辛斯托克,英国)辅以5%的去纤维蛋白的马血(国家兽医研究所(SVA),乌普萨拉,瑞典)]的金黄色葡萄球菌(#1800;CCUG,哥德堡,瑞典)被转移到脑心灌注肉汤(3.7%BHI;Difco,BDDiagnostics,富兰克林湖,新泽西州,美国)并以250rpm+37℃在摇床上孵育过夜。然后培养物用新鲜BHI肉汤以1:10稀释并额外孵育两个小时到达对数期增长。所述细菌聚团并用1%BHI培养基(BHI肉汤用超纯水稀释100倍)重悬至终浓度为107细菌/ml,通过在600nm测量光学密度估计所述菌液浓度。
肽在1%的BHI培养基中或50%热灭活的刺激过的伤口渗出液[SWF,含有一份0.1%胨(Oxoid,贝辛斯托克,英国)的生理盐水和一份胎牛血清,用超纯水稀释两倍]中,从400μΜ到0.78μΜ以两倍梯度系列稀释。
然后所述肽(100μl)与细菌(5μl的浓度为107细菌/ml)在+37℃孵育2小时。悬液滴(5μl)置于血琼脂平板。血琼脂板在+37℃孵育过夜。记录MMC99值,即达到减少99%的细菌所需的最低肽浓度(表6)。在测定中使用的细菌悬液的浓度通过血液琼脂平板活菌计数进行验证。

类型2的肽
肽的多个变种通过增加荷电和添加疏水区来设计。特别是两亲性的调节对于得到高活性的肽是重要的。
基于使用类型2的肽序列和抗炎测定的结果进行的主成分分析法(ProPHECYTM),确定了三个不同集群的活性肽(图3)。群集只载肽的筛选回合2。在表7中总结了每个群集中最具活性的肽。
在图3中的散点图基于肽属性的主成分分析。所述肽已经过比对并且每个氨基酸的理化属性也考虑到了。在绘图中彼此接近的肽也预期具有更高程度的相似性。就是说,所述肽在大部分位点具有相同或相似的氨基酸。相应地,有距离的肽预计具有更多不同的序列。例如,肽232和244都非常接近(见集群A)并且所述肽在3个位点有差异,其中232有R、R和M,244有K、K和W(R与K、以及M与W,不是非常不同)。这可以与除了8个位点的不同之外长度上相差两个氨基酸的肽240和249(分别群集B和C)形成对比,不同长度除了在8个位点的差异中的两个残留量的比较。因此,得分绘图提供了所述肽之间理化相似度的概况。
表7:类型2的肽
粗体的残基标示对活性作出积极贡献的氨基酸类型。
表7中的结果概述易于来鉴定对于高活性重要的位点和突变。在这些肽中多个位点已经被替换为带正电荷的氨基酸例如Lys(K)和Arg(R)。另外,所个位点已经被变成疏水氨基酸以增加肽末端的疏水性并增加和调节两亲性。ProPHECYTM分析显示在位点1和2以及位点5具有带正电荷的氨基酸是有益的。进一步,在位点7、8和12上疏水性氨基酸是有益的。所有这些肽在位点3具有Leu(L)。如果位点7、8和12变成疏水残基或者变成为疏水性提高的残基(如在肽244中Met变为Trp)
集群B中的肽在N-末端和C-末端都延长了一个或两个残基以增加正电荷和疏水性。肽240具较低活性是由于此肽所带正电荷以及两亲性较低。具有最高活性的肽239和241在位点2和5具有带正电荷的氨基酸并且在位点3和7具有疏水性氨基酸。
在集群C的肽中,两亲性已经位移并扭转到所述肽的表面的另一部分。这是通过位点1、5、9和12替换为疏水性氨基酸并且在位点2、3、7和11替换为带正电荷的氨基酸来实现的。
最终,一些属于集群A以及特别是集群B的有活性的类型2的肽甚至在接近生理盐浓度下都表现出高的抗微生物作用。
实施例3.体外抗微生物的作用
通过MMC99(最小微生物杀伤浓度)测定法分析肽232(SEQIDNO:78)和肽220(SEQIDNO:67)对金黄色葡萄球菌(CCUG1800)、MRSA(CCUG41879)、假单胞菌(ATCC15442)、大肠杆菌(CCUG31246)、化脓性链球菌(CCUG4207)、痤疮丙酸杆菌(CCUG1794T)、表皮葡萄球菌(ATCC12228)、肺炎克雷伯菌(ATCC13883)、鲍曼不动杆菌(ATCC19606)和白色念球菌(ATCC64549)的抗微生物的作用。肽从Biopeptide公司(亚圣迭戈,加利福尼,美国)和BachemAG(Bubendorf,瑞士)购买并且结果分别显示于表8A和8B。
肽在两种不同的检测培养基中进行系列稀释,即1%BHI培养基(脑心灌注培养基)或50%热灭活的刺激过的伤口渗出液(SWF),然后与微生物有机体孵育2小时。悬液滴置于血琼脂平板。记录MMC99值,即达到减少99%的细菌所需的最低肽浓度。如表8所示,所述肽具有杀死在感染中常出现的微生物有机体的能力。
表8A.用MMC99(μg/ml)测量体外抗微生物的作用
表8B.用MMC99(μg/ml)测量体外抗微生物的作用
实施例4.在大鼠切除伤口模型上的体内抗微生物作用
肽232(SEQIDNO:78)和肽220(SEQIDNO:67)的体内抗微生物的作用在大鼠切除伤口模型上进行了研究。伤口用耐甲氧西林的金黄色葡萄球菌(MRSA)接种2小时,接着一次性施用肽或对照(水)2小时后终止并收获细菌。所有肽显示明显的抗微生物作用(图4)。
实施例5.在猪的被感染伤口上的体内抗微生物作用
肽232(SEQIDNO:78)和肽220(SEQIDNO:67)的抗微生物的作用在猪皮的离体模型上进行了研究。伤口用存在于PBS/血清(50/50)的金黄色葡萄球菌接种。接种2小时后伤口一次性施用肽或者安慰剂(水)。处理4小时之后收获细菌并且确定每个伤口的活菌计数。上述结果证实了大鼠上的发现,说明了所述肽在局部施用时是高效的抗感染试剂(图5)。
