1.本发明涉及有机化学领域,特别是涉及一种小分子去垢剂。
背景技术:2.膜蛋白是一大类重要的药物靶标。人类基因组大约有20-30%表达的是膜蛋白,与此同时,当前fda批准的药物中,大约有50%的靶标是膜蛋白。因此,对于膜蛋白的结构及生理功能的研究极其重要。然而,膜蛋白的研究难度却高于可溶性蛋白——膜蛋白只能在膜或拟膜的两亲环境中稳定存在并维持功能,不能在水中维持稳定。膜蛋白的研究也滞后于可溶性蛋白。全世界最大的结构生物学数据库rcsb中,膜蛋白的结构仅占全部收录蛋白的2%。限制膜蛋白研究的瓶颈之一是膜蛋白的纯化技术。膜蛋白的纯化是指利用拟膜试剂将生物膜上的膜蛋白萃取至水溶液中,并通过各种纯化手段使目标膜蛋白与其它组分分离。纯化得到的膜蛋白需维持自身的高级结构与功能活性与膜蛋白仍处在膜上的两亲环境相似,即“拟膜”的效果。在各种拟膜试剂中,最常用的是小分子去垢剂,具有适用范围广、对膜蛋白稳定性好、成本低廉等诸多优点。目前,针对各种不同家族的膜蛋白,人们已发展了多种去垢剂。其中,正辛基-β-d-吡喃葡萄糖苷(n-octyl-β-d-glucopyranoside,og)、十二烷基-β-d-麦芽糖苷(n-dodecyl-β-d-maltoside,ddm)、十二烷基新戊二醇麦芽糖苷(lauryl maltose neopentyl glycol,lmng)、磷酰胆碱系列(fos-cholines)等是目前应用最为广泛的去垢剂。然而,膜蛋白的数量非常庞大,目前并没有证据表明存在单一的去垢剂能够很好的维持所有膜蛋白的稳定性。因此,为了应对膜蛋白的多样性,发展去垢剂的多样性具有重要的意义。
技术实现要素:3.鉴于以上所述现有技术的缺点,本发明的目的在于提供一种小分子去垢剂,用于解决现有技术中的问题。

分别对实施例2中表征的小分子去垢剂进行膜蛋白热稳定性实验:
[0303]
1、a2ar的表达、纯化与热稳定性测试。
[0304]
腺苷受体2a(a2ar)是一种g蛋白偶联受体。在此实施例中使用的是人工改造过的a2ar-bril-δc结构(pdb:4eiy,以下简称a2ar)。通过杆状病毒侵染昆虫细胞sf9的方式将a2ar表达在细胞中。将细胞培养至2
×
106个/ml浓度,然后使用6000g转速离心10分钟收集细胞。
[0305]
将细胞用低盐缓冲液(10mm mgcl2,20mm kcl,蛋白酶抑制剂(roche),10mm 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid(hepes),ph 7.5)重悬并破碎,使用35000rpm转速离心30分钟,弃去上清液,底部的沉淀重复上述低盐洗涤2次,然后使用高盐缓冲液(1m nacl,10mm mgcl2,20mm kcl,10mm hepes,ph 7.5)重复上述洗涤-离心步骤2次。这样最终得到含有a2ar的固体膜用重悬缓冲液(10mm mgcl2,20mm kcl,30%(v/v)glycerol,100μm zm241385(4-[2-[[7-amino-2-(2-furanyl)[1,2,4]-triazolo[1,5-a][1,3,5]triazin-5-yl]amino]ethyl]phenol),2mg/ml碘乙酰胺,10mm hepes,ph 7.5)重悬,在4℃下孵育1小时。之后重悬液加入等体积的溶膜缓冲液(800mm nacl,1%(w/v)ddm,50mm hepes,ph 7.5),继续在4℃下孵育2.5小时。将此悬浊液用35000rpm转速离心30分钟,收集上清液,加入20mm咪唑、talon金属亲和固定树脂(clontech),孵育过夜。如此操作后,a2ar被收集并固定在树脂上。此树脂依次用洗涤缓冲液i(800mm nacl,10%甘油,8mm三磷酸腺苷(atp),10mm mgcl2,20mm咪唑,100μm zm241385,0.1%ddm,50mm hepes,ph 7.5)及洗涤缓冲液ii(500mm nacl,10%甘油,20mm咪唑,100μm zm241385,0.05%ddm,50mm hepes,ph 7.5)洗涤,然后用洗脱缓冲液(500mm nacl,10%甘油,250mm咪唑,100μm zm241385,0.025%ddm,25mm hepes,ph 7.5)洗脱得到膜蛋白a2ar的ddm溶液。
[0306]
a2ar在不同去垢剂样品的制备:将去垢剂缓冲液与a2ar的ddm溶液混合,使50μl样品中含有1μg a2ar、40μm zm241385、0.2%(w/v)去垢剂、500mm nacl、10%甘油、25mm hepes,ph 7.5。将荧光染料n-([4-(7-diethylamino-4-methyl-3-coumarinyl)phenyl]-maleimide(cpm)的dmso储液(4mg/ml)加入上述样品中,使荧光染料的终浓度为2μg/ml,在4℃下孵育15分钟。之后将样品置于高通量荧光分光光度计(rotor-gene q,qiagen)中逐渐升温并记录荧光值随温度变化的结果,激发波长365nm,发射波长460nm,升温速率1℃/min。使用graph pad prism处理数据,使用玻尔兹曼s型函数(boltzmann sigmoidal)拟合数据并得到每个样品的tm值。测试同时使用ddm和lmng作为对照去垢剂。

a2ar在各种去垢剂中的tm值测定结果如表4所示(单位:℃):

对照用去垢剂结果:ddm:47.22℃;lmng:50.97℃。
[0311]
上述实施例中大部分的去垢剂在膜蛋白热稳定性实验的结果优于对照去垢剂ddm。部分去垢剂甚至优于lmng,后者被认为对于多种膜蛋白的稳定性具有非常优异的表现。这一现象在类型3去垢剂中尤为显著。

综上所述,本发明有效克服了现有技术中的种种缺点而具高度产业利用价值。
