Click Chemistry由K.Barry Sharpless、Hartmuth C.Kolb和M.G.Finn于2001年提出,用于描述快速選擇性反應(yīng)或以可預(yù)測(cè)的方式相互“點(diǎn)擊”以形成具有雜原子鏈(C-X-C)的生理穩(wěn)定產(chǎn)物的反應(yīng)。Click chemistry廣泛用于生物分子、表面、顆粒和有機(jī)化合物的改性,具有許多優(yōu)點(diǎn)1:
* 應(yīng)用范圍廣泛;
* 模塊化性質(zhì);
* 在“小量”和“大量”反應(yīng)中均適用;
* 反應(yīng)條件溫和;
* 產(chǎn)品分離簡(jiǎn)單(幾乎不需要純化);
* 產(chǎn)率高,速度快;
* 無害副產(chǎn)品生成(遵循綠色化學(xué)的12項(xiàng)原則);
* 兼容性良好,尤其在生命系統(tǒng)中(允許生物分子的化學(xué)選擇性修飾,幾乎不受干擾)2。
在大約10種不同類型的點(diǎn)擊反應(yīng)中,有幾種是在各種生命科學(xué)應(yīng)用中使用最頻繁,從“簡(jiǎn)單”的生物分子標(biāo)記和檢測(cè)到先進(jìn)的CRISPER應(yīng)用。在此,我們重點(diǎn)介紹最重要的9種(最新)應(yīng)用:
* 生物分子標(biāo)記與檢測(cè)
*(固&液相)生物分子修飾/連接
* 構(gòu)建用于構(gòu)效關(guān)系分析的類似物庫(kù)
* 藥物先導(dǎo)化合物發(fā)現(xiàn)
* 藥物輸送
* 材料優(yōu)化(聚合物改性)
* 病毒研究探針
* CRISPER sgRNA合成和靶基因標(biāo)記
* 新應(yīng)用,包括“點(diǎn)擊發(fā)布”
Click chemistry十分有用的功能之一是它能夠標(biāo)記和可視化生物分子,如脂質(zhì)3、肽4、聚糖5、糖蛋白6、核酸和合成分子7,8(如紫杉醇9),并且具有最小的生理干擾性(體外和體內(nèi))10。在進(jìn)行標(biāo)記的兩步反應(yīng)中,首先用雙正交點(diǎn)擊手柄(如炔烴或疊氮化物)標(biāo)記目標(biāo)生物分子(酶、代謝11,12或合成(請(qǐng)見圖1)9,13)。然后當(dāng)一個(gè)分子上有熒光或親和基團(tuán)的互補(bǔ)點(diǎn)擊手柄與目標(biāo)分子發(fā)生點(diǎn)擊反應(yīng)時(shí),就會(huì)發(fā)生檢測(cè)/可視化。
例如,在活體發(fā)育的斑馬魚中,表面聚糖以亞細(xì)胞分辨率被觀察到;依靠基因編碼的傳統(tǒng)分子成像方法通常無法看見14。在這項(xiàng)研究中,Bertozzi等人將代謝糖工程與多色檢測(cè)策略相結(jié)合,以揭示細(xì)胞表面表達(dá)、細(xì)胞內(nèi)運(yùn)輸和整個(gè)斑馬魚胚胎發(fā)生過程中聚糖組織分布的差異。類似的研究也在小鼠中進(jìn)行,以跟蹤移植細(xì)胞和測(cè)定細(xì)胞對(duì)肽的攝取情況,這有助于結(jié)構(gòu)-活性-通透性關(guān)系優(yōu)化研究15。兩個(gè)位點(diǎn)標(biāo)記生物分子(稱為雙位點(diǎn)標(biāo)記)有效的促進(jìn)了復(fù)雜生物系統(tǒng)的研究16,17,18,19,20。
肽、核苷酸、小分子、超分子等都可以通過固相或液相點(diǎn)擊化學(xué)進(jìn)行修飾,幾乎無需使用保護(hù)基團(tuán),也無需產(chǎn)品純化3,21,22??傮w來講,固相合成更快,且需要更少的后處理,但是每種方法都各有優(yōu)缺點(diǎn)23,24。
類似物庫(kù)可以通過點(diǎn)擊化學(xué)快速可靠地構(gòu)建,無需太多的合成工作,然后通過原位高通量篩選(HTS)來促進(jìn)分子結(jié)構(gòu)-活性關(guān)系(SAR)分析,這是優(yōu)化和發(fā)現(xiàn)生物活性分子所必需的。已經(jīng)有許多基于click(三唑)骨架的片段庫(kù)(聚焦組合)通過此方法被構(gòu)建出來25,例如Janus激酶抑制劑ruxolitinib衍生的三唑文庫(kù),它被用來評(píng)估JAK3抑制劑24 。
原位點(diǎn)擊化學(xué)是一種(動(dòng)力學(xué))靶點(diǎn)導(dǎo)向合成方法,Sharpless及其同事于2002年第一次提出并應(yīng)用于發(fā)現(xiàn)一種有效的乙酰膽堿酯酶抑制劑26。這種方法使用目標(biāo)生物分子本身作為支架,如果使其足夠接近并以適當(dāng)?shù)姆较蚍磻?yīng),則結(jié)合配體在其上進(jìn)行咔噠反應(yīng)。通過這種方式,可以從帶有互補(bǔ)反應(yīng)性官能團(tuán)的片段庫(kù)中篩選出能夠與目標(biāo)物形成穩(wěn)定絡(luò)合物的最佳配體27。無需事先對(duì)文庫(kù)成員進(jìn)行合成、純化和生化評(píng)估,即可快速且經(jīng)濟(jì)高效地篩選大量化合物28,29。
碳酸酐酶30、HIV蛋白酶31、幾丁酶32、核苷酸配體33、蛋白質(zhì)-蛋白質(zhì)相互作用(通過磺基點(diǎn)擊化學(xué))34、抗體樣蛋白質(zhì)捕獲劑35,36、轉(zhuǎn)錄因子37、通道38等的抑制劑也已被表征。
藥物進(jìn)入人體的控制給藥是有效藥物設(shè)計(jì)的一個(gè)重要方面。點(diǎn)擊化學(xué)已用于構(gòu)建聚合物納米和微粒藥物遞送系統(tǒng)(DDS),如聚合物膠束、脂質(zhì)體、膠囊、碳納米管等6,39。
在材料制造領(lǐng)域,從線性聚合物和接枝聚合物到更復(fù)雜結(jié)構(gòu)(如星形聚合物、嵌段共聚物和樹狀聚合物)的合成,再到表面和界面的功能化40,點(diǎn)擊化學(xué)都產(chǎn)生了巨大的影響。例如,由于不產(chǎn)生小分子副產(chǎn)物,點(diǎn)擊化學(xué)可以最大限度地減少氣泡、空穴和不規(guī)則的形成,就像其他縮聚反應(yīng)一樣,這些氣泡、空穴和不規(guī)則會(huì)破壞新合成熱固性材料的外觀和性能41。
CuAAC click chemistry還被用作一種高效、環(huán)保的交聯(lián)策略,以改善適用于涂料和粘合劑的水性聚合物的性能42(下圖2)。廣泛適用于聚氨酯(WPU)、聚酯分散體(PED)和聚丙烯酸酯乳液(PAE),該策略優(yōu)于其他可用的交聯(lián)策略(包括基于N-羥甲基丙烯酰胺(NMA)、懸垂乙酰乙酸基團(tuán)和可逆酮酰肼反應(yīng)的自交聯(lián)系統(tǒng))。Click交聯(lián)聚合物薄膜的機(jī)械強(qiáng)度、硬度和耐水/溶劑性能顯著提高,為工業(yè)涂料應(yīng)用中使用硬化劑提供了一種有可能降低成本的替代品。
此外,各種(1D、2D、3D)生物材料(如水凝膠)的合成在組織工程43,44,45,46再生醫(yī)學(xué)47、藥物輸送48和基因治療領(lǐng)域49也越來越受到重視。
在過去幾十年中50,與病毒相關(guān)的研究,包括病毒(蛋白質(zhì)、核酸或病毒粒子)追蹤51,52、抗病毒設(shè)計(jì)53,54、診斷55,56,57和基于病毒的傳遞系統(tǒng)58,59都使用了點(diǎn)擊化學(xué)。例如,通過將疊氮化物修飾的病毒粒子連接到由二苯并環(huán)辛烯(DBCO)衍生的量子點(diǎn)(QD),使用無銅點(diǎn)擊反應(yīng)來標(biāo)記包膜病毒(痘苗病毒(VACV)和A病毒(H9N2))。標(biāo)記效率達(dá)到80%以上,不干擾病毒的感染能力,熒光強(qiáng)度足以實(shí)現(xiàn)單個(gè)病毒粒子的跟蹤60。
Click chemistry現(xiàn)在可以在CRISPR工具箱中找到合成單個(gè)或多個(gè)單一導(dǎo)向RNA(sgRNA)的位置,繞過了與(更長(zhǎng))寡聚體長(zhǎng)度相關(guān)的現(xiàn)有合成限制,并縮短sgRNA設(shè)計(jì)和應(yīng)用之間的時(shí)間。
Click chemistry(被稱為“分裂和點(diǎn)擊”)不是一次性制造整個(gè)sgRNA,而是簡(jiǎn)單地連接兩個(gè)更小(更容易合成)的片段:一個(gè)按需制備的高純度~20-mer(crRNA)靶向序列和一個(gè)通用的可大規(guī)模生產(chǎn)的79-mer CRISPR內(nèi)切酶蛋白(Cas9)序列(tracrRNA)。結(jié)果發(fā)現(xiàn),帶有三唑鍵的~99-聚體能夠在體外和細(xì)胞內(nèi)有效地進(jìn)行Cas9介導(dǎo)的DNA切割,其靶向性與體外轉(zhuǎn)錄的sgRNA相當(dāng)61。
點(diǎn)擊化學(xué)也被用于標(biāo)記靶基因(稱為sgRNA點(diǎn)擊(sgR CLK))62。該技術(shù)包括在體外轉(zhuǎn)錄的CRISPR-sgRNA的3′端安裝點(diǎn)擊手柄,以形成疊氮化物標(biāo)記的三元復(fù)合物(由dCas9、sgRNA和靶基因組成)。然后通過與炔烴對(duì)應(yīng)物的點(diǎn)擊反應(yīng)實(shí)現(xiàn)該三元絡(luò)合物的功能化。
此外,點(diǎn)擊化學(xué)還用于設(shè)計(jì)一種柔性樹枝狀聚合物,用于傳遞鋅指、TALEs和CRISPR/dCas9平臺(tái)。使用該方法具有高轉(zhuǎn)染效率和較大的處理量63。
除了連接,點(diǎn)擊化學(xué)現(xiàn)在正在探索解封或“點(diǎn)擊釋放”應(yīng)用,這使得探針激活和治療傳遞的新策略成為可能64,65,66。例如,利用逆電子需求Diels-Alder-噠嗪消除反應(yīng)在體外和腫瘤小鼠中激發(fā)阿霉素從抗體-藥物結(jié)合物(ADC)中的快速釋放67。
點(diǎn)擊化學(xué)還被用于開發(fā)新的的微芯片和毛細(xì)管系統(tǒng)68,如微流控“點(diǎn)擊芯片”69和基于石墨烯的“點(diǎn)擊芯片”70。此外,“電點(diǎn)擊”接合方法已被用于固定酶(用于生物傳感器)、制備電化學(xué)免疫傳感器以及在空間和時(shí)間上控制蛋白質(zhì)接合71,72,73。
