專利名稱：篩選在瘧原蟲中抑制gpi生物合成的化合物的方法
技術(shù)領(lǐng)域：
本發(fā)明涉及篩選在瘧原蟲中抑制GPI生物合成的化合物的方法。
背景技術(shù)：
瘧疾是由寄生性原蟲引起的最常見的傳染性人類疾病。該疾病由于感染瘧原蟲所致，以蚊子，岡比亞瘧紋(Anopheles gambiae)為媒介。每年約有50億病例感染瘧疾，包括超過兩百萬(wàn)的致死例(Gardner等，Nature419498-511，2003)。目前，40％的世界人口生活在瘧疾流行區(qū)，在該區(qū)域據(jù)說(shuō)每3名新生兒中就有一名死于瘧疾。
已知糖基磷脂酰肌醇(GPI)在寄生蟲生長(zhǎng)和感染過程中起著重要的作用，所述寄生蟲包括瘧原蟲。在這些寄生蟲的細(xì)胞表面上有許多GPI-錨定蛋白。GPI-錨定蛋白包括如在寄生蟲侵入紅細(xì)胞時(shí)起作用的MSP-1蛋白。GPI-錨定蛋白起寄生蟲抗原的作用，在宿主中引發(fā)免疫應(yīng)答。因此，它們長(zhǎng)期以來(lái)是疫苗開發(fā)的研究對(duì)象。
GPI不僅作為將蛋白拴到細(xì)胞膜的錨，而且是瘧原蟲細(xì)胞膜的豐富糖脂成分。最近的研究揭示GPI有毒，并能促成致死癥狀。GPI誘導(dǎo)炎性細(xì)胞因子如TNF-α和粘附分子的表達(dá)。結(jié)果，受染紅細(xì)胞粘附毛細(xì)管，阻塞血管(隔離作用(sequestration))，尤其是腦血管。它能引起進(jìn)一步的炎癥反應(yīng)，而炎癥反應(yīng)認(rèn)為能導(dǎo)致腦病。最近，Schofield等報(bào)道抗-GPI抗體降低利用鼠科瘧原蟲伯氏瘧原蟲(Plasmodium berghei)創(chuàng)建的體內(nèi)感染模型系統(tǒng)的致死率，并且該抗體在體外抑制由惡性瘧原蟲(Plasmodium falciparum)引起的后期炎癥反應(yīng)(Schofield L等，Nature 418785-789，2002)。此發(fā)現(xiàn)說(shuō)明GPI是瘧疾感染致死率的主要因素。
還報(bào)道肌醇?；瘜?duì)于甘露糖與GPI的結(jié)合來(lái)說(shuō)是必需的(Gerold，P.等，Biochem.J.344731-738，1999)，由過量葡糖胺引起的肌醇酰基化的抑制會(huì)抑制惡性瘧原蟲的成熟(Naik，R.S.等，J.Biol.Chem.2782036-2042，2003)。因此，選擇地抑制GPI生物合成尤其是肌醇?；幕衔锟梢允欠浅Ｓ杏玫目汞懰幬铩?br> 發(fā)明的公開本發(fā)明的目的是提供抑制GPI生物合成的抗瘧藥物。更具體地說(shuō)，本發(fā)明提供了編碼GWT1蛋白的瘧原蟲DNA，所述蛋白是參與GPI生物合成的蛋白質(zhì)(GPI合酶)。本發(fā)明還提供了在篩選抗瘧藥物的方法中利用該DNA的方法。本發(fā)明還提供了編碼瘧原蟲GPI生物合成蛋白的DNA的簡(jiǎn)并突變體DNA。該簡(jiǎn)并突變體DNA比天然DNA具有更低的AT含量。本發(fā)明還提供了在篩選抗瘧藥物的方法中利用該簡(jiǎn)并突變體DNA的方法。
最早發(fā)現(xiàn)GWT1基因編碼真菌GPI-錨定蛋白合酶(WO 02/04626)，其在從酵母到人類的生物體中是保守的。本發(fā)明人證實(shí)GWT1同源物(惡性瘧原蟲(P.falciparum)GWT1的PfGWT1；約氏瘧原蟲(P.yoelii yoelii)GWT1的PyGWT1)包括在惡性瘧原蟲和約氏瘧原蟲的全基因組序列內(nèi)(Gardner等，Nature 419498-511，2003；Carlton等，Nature 419512-519，2003)。本發(fā)明人還發(fā)現(xiàn)GWT1基因產(chǎn)物在GPI生物合成途徑中起GlcN-PI?；D(zhuǎn)移酶的作用。PfGWT1基因產(chǎn)物期望具有相似的活性，這樣抑制其活性的化合物就可能是有價(jià)值的抗瘧藥物。
在WO 02/04626中，本發(fā)明人發(fā)現(xiàn)了一組抑制真菌GWT1基因產(chǎn)物的活性的化合物。抑制PfGWT1基因產(chǎn)物的活性的化合物有望成為抗瘧藥物。
在本發(fā)明中，本發(fā)明人成功地對(duì)幾乎是PfGWT1全長(zhǎng)的區(qū)域進(jìn)行了分離。利用瘧原蟲如惡性瘧原蟲的GWT1基因產(chǎn)物，抗瘧藥物的篩選可以通過結(jié)合試驗(yàn)，葡糖胺(?；?磷脂酰肌醇(PI-GlcN)?；D(zhuǎn)移酶試驗(yàn)，或利用GPI-錨定蛋白檢測(cè)系統(tǒng)來(lái)進(jìn)行。從所述篩選方法獲得的化合物可能是有價(jià)值的抗瘧藥物。更進(jìn)一步地，本發(fā)明人揭示簡(jiǎn)并突變體DNA(編碼瘧原蟲GPI生物合成蛋白的DNA簡(jiǎn)并突變體)，該DNA比天然DNA具有更低AT含量，補(bǔ)償GWT1基因-缺陷型真菌的表型。因此，利用GPI合酶基因-缺陷型真菌的表型作為指標(biāo)，該真菌中導(dǎo)入了(比瘧原蟲中編碼GPI生物合成蛋白的DNA)具有更低AT含量的簡(jiǎn)并突變體DNA，就有可能篩選出抑制在瘧原蟲中參與GPI生物合成的蛋白活性的化合物。

本發(fā)明提供了編碼瘧原蟲GWT1蛋白的DNA。所述DNA包括編碼包含SEQ ID NO2或4氨基酸序列的蛋白的DNA，和包含SEQ ID NO1或3核苷酸序列的DNA。

篩選與標(biāo)記化合物競(jìng)爭(zhēng)結(jié)合瘧原蟲GWT1基因產(chǎn)物的化合物的結(jié)合試驗(yàn)本發(fā)明的兩種方法公開如下，即(1)制備瘧原蟲GWT1基因產(chǎn)物(下文中稱為瘧原蟲GWT1蛋白)的方法和(2)涉及標(biāo)記化合物的結(jié)合實(shí)驗(yàn)法(下文中稱為結(jié)合試驗(yàn))
(1)制備瘧原蟲GWT1蛋白的方法瘧原蟲GWT1蛋白是從細(xì)胞膜級(jí)分，優(yōu)選從真菌細(xì)胞，更優(yōu)選從釀酒酵母(S.cerevisiae)細(xì)胞中制得的，其中引入了SEQ ID NO2的瘧原蟲GWT1蛋白的編碼DNA。優(yōu)選將所述DNA導(dǎo)入GWT1基因-缺陷型細(xì)胞中。在結(jié)合試驗(yàn)中，可以在未進(jìn)行任何其它處理的條件下使用所制的膜級(jí)分，或者在使用前對(duì)膜級(jí)分進(jìn)行進(jìn)一步的純化。利用釀酒酵母的方法將在下面進(jìn)行詳細(xì)描述。
(a)瘧原蟲GWT1基因的導(dǎo)入本發(fā)明使用的瘧原蟲GWT1基因可以是天然存在的基因，或優(yōu)選是基于SEQ ID NO2或4的氨基酸序列進(jìn)行合成的。瘧原蟲GWT1基因富含腺嘌呤和胸腺嘧啶。因此，可以推斷利用常規(guī)的基因重組技術(shù)將很難對(duì)該基因進(jìn)行操作，且該基因在酵母，細(xì)胞等中的表達(dá)效率將會(huì)很低(inefficient)。因此，優(yōu)選對(duì)核苷酸序列進(jìn)行設(shè)計(jì)，將其中與每個(gè)相應(yīng)氨基酸對(duì)應(yīng)的密碼子替換為那些認(rèn)為可以在酵母，細(xì)胞等中能有效表達(dá)的密碼子，在該設(shè)計(jì)序列的基礎(chǔ)上進(jìn)行DNA合成，制備人工的瘧原蟲GWT1基因，然后在下述實(shí)驗(yàn)中使用該基因。
瘧原蟲GWT1的表達(dá)質(zhì)粒是通過將瘧原蟲GWT1基因插入到釀酒酵母表達(dá)載體內(nèi)來(lái)加以制備的，例如，通過將適合的啟動(dòng)子和終止子，如pKT10-衍生的GAPDH啟動(dòng)子和GAPDH終止子，插到Y(jié)Ep352的多克隆位點(diǎn)內(nèi)來(lái)制備表達(dá)載體(Tanaka等，Mol.Cell Biol.，104303-4313，1990)。將釀酒酵母(如G2-10菌株)培養(yǎng)在合適的培養(yǎng)基(如YPD培養(yǎng)基(酵母提取物-聚蛋白胨-葡萄糖培養(yǎng)基))中，并在適宜的溫度(如30℃)振蕩，在對(duì)數(shù)生長(zhǎng)晚期收獲細(xì)胞。洗滌后，采用如乙酸鋰法將GWT1-表達(dá)質(zhì)粒導(dǎo)入釀酒酵母細(xì)胞中。該方法描述于User Manual of YEAST MAKERTMYeast Transformation System(BD Biosciences Clontech)。瘧原蟲GWT1-過表達(dá)菌株和攜帶陰性對(duì)照載體的菌株可通過將轉(zhuǎn)化細(xì)胞于30℃，在SD(ura-)培養(yǎng)基上培養(yǎng)兩天而獲得。

(b)制備膜級(jí)分的方法在適合的培養(yǎng)基(如SD(ura-)液體培養(yǎng)基)中培養(yǎng)，并在適合的溫度(如30℃)振蕩導(dǎo)入了瘧原蟲GWT1基因的釀酒酵母細(xì)胞。在對(duì)數(shù)生長(zhǎng)中期時(shí)收獲真菌細(xì)胞，然后用合適量(如真菌細(xì)胞的3倍體積)的勻漿緩沖液(如50mMTris-HCl，pH 7.5，10mM EDTA，CompleteTM(Roche))懸浮。將合適量的玻璃珠(如真菌細(xì)胞的4倍體積)加至懸浮液中。渦旋混合物，并置于冰上。重復(fù)此操作數(shù)次將真菌細(xì)胞破碎。
將1毫升的勻漿緩沖液加入所得的裂解液中。離心混合物；如2,500rpm離心5分鐘，使玻璃珠和未碎的真菌細(xì)胞沉淀。將上清液移到另一試管內(nèi)。離心該試管，如13,500rpm離心10分鐘，使含有細(xì)胞器的膜級(jí)分(總膜級(jí)分)沉淀。用1ml結(jié)合緩沖液(如0.1M磷酸鹽緩沖液，pH 7.0，0.05％Tween 20，CompleteTM(Roche))懸浮沉淀物，然后離心，如2,500rpm離心1分鐘，除去未懸浮的物質(zhì)。然后離心上清液，如15,000rpm離心5分鐘。沉淀物用150-650μl的結(jié)合緩沖液重懸浮來(lái)制備膜級(jí)分。
采用適合粟酒裂殖酵母的Yoko-o等的方法(Eur.J.Biochem.257630-637，1998)；適合白色念珠菌的Sentandreu M等的方法(J.Bacteriol.，180282-289，1998)；適合煙曲霉的Mouyna I等的方法(J.Biol.Chem.，27514882-14889，2000)；和適合新生隱球菌的Thompson JR等的方法(J.Bacteriol.，181444-453，1999)可以從除釀酒酵母之外的真菌物種中制備膜級(jí)分。
另外，可以通過在大腸桿菌，昆蟲和哺乳動(dòng)物細(xì)胞或其他非真菌細(xì)胞中表達(dá)來(lái)制備瘧原蟲GWT1蛋白。
當(dāng)使用哺乳動(dòng)物細(xì)胞時(shí)，將瘧原蟲GWT1基因與含有如CMV啟動(dòng)子的過表達(dá)載體連接，導(dǎo)入哺乳動(dòng)物細(xì)胞中。然后，按照Petaja-Repo等的方法(J.Biol.Chem.，2764416-23，2001)制備膜級(jí)分。
表達(dá)瘧原蟲GWT1基因的昆蟲細(xì)胞(如Sf9細(xì)胞)可以利用，例如桿狀病毒表達(dá)試劑盒如BAC-TO-BAC桿狀病毒表達(dá)系統(tǒng)(Invitrogen)來(lái)進(jìn)行制備。然后，按照Okamoto等的方法(J.Biol.Chem.，276742-751，2001)制備膜級(jí)分。

將已適當(dāng)標(biāo)記的，優(yōu)選放射性標(biāo)記的GlcN-(?；?PI前體(如UDP-GlcNAc，Acyl-輔酶A，優(yōu)選UDP-[14C]GlcNAc)加到混合物中。將所得的混合物孵育適當(dāng)長(zhǎng)的時(shí)間(如24℃孵育1小時(shí))。加入氯仿和甲醇(1∶2)的混合物，攪拌所得混合物以使反應(yīng)停止，提取脂質(zhì)。將提取的反應(yīng)產(chǎn)物溶解在合適的溶劑中，優(yōu)選丁醇。然后，利用如HPLC或薄層層析(TLC)，優(yōu)選TLC法分離反應(yīng)產(chǎn)生的GlcN-(?；?PI。當(dāng)使用TLC時(shí)，展開劑(developing solvent)可以適當(dāng)?shù)剡x自，如CHCl3/CH3OH/H2O(65∶25∶4)，CHCl3/CH3OH/1M NH4OH(10∶10∶3)和CHCl3/吡啶/HCOOH(35∶30∶7)。優(yōu)選的展開劑是CHCl3/CH3OH/H2O(65∶25∶4)。采用對(duì)所用標(biāo)記而言恰當(dāng)?shù)姆椒?，?duì)分離的GlcN-(酰基)PI進(jìn)行定量。當(dāng)用放射性同位素作標(biāo)記時(shí)，可以基于其放射性對(duì)分離的GlcN-(?；?PI進(jìn)行定量。
當(dāng)在試樣存在的條件下，制得的GlcN-(?；?PI量減少時(shí)，就判定該試樣具有抑制由瘧原蟲GWT1蛋白引起的?；D(zhuǎn)移的活性。
包括在細(xì)胞中表達(dá)瘧原蟲GWT1蛋白然后檢測(cè)細(xì)胞表面上的GPI-錨定蛋白的GPI-錨定蛋白檢測(cè)系統(tǒng)試樣抑制瘧原蟲GWT1蛋白活性的能力可以利用GPI-錨定蛋白檢測(cè)系統(tǒng)來(lái)進(jìn)行測(cè)定，該系統(tǒng)包括在細(xì)胞，優(yōu)選真菌細(xì)胞中表達(dá)GWT1蛋白，然后檢測(cè)細(xì)胞表面上的GPI-錨定蛋白。本發(fā)明的真菌是指屬于接合菌門(Zygomycota)，子囊菌門(Ascomycota)，擔(dān)子菌門(Basidiomycota)及半知菌綱(Deuteromycete)的真菌，且優(yōu)選的真菌是致病性真菌，毛霉屬(Mucor)，酵母屬(Saccharomyces)，念珠菌屬(Candida)，隱球菌屬(Cryptococcus)，絲孢酵母屬(Trichosporon)，鱗斑霉屬(Malassezia)，曲霉屬(Aspergillus)，發(fā)癬菌屬(Trichophyton)，小孢子菌屬(Microsporum)，孢子絲菌屬(Sporothrix)，芽生酵母屬(Blastmyces)，球孢子菌屬(Coccidioides)，副球孢子菌屬(Paracoccidioides)，青霉屬(Penicillinium)和鐮孢屬(Fusarium)，更優(yōu)選的真菌為白色念珠菌，光滑念珠菌(C.glabrata)，新生隱球菌和煙曲霉，甚至更優(yōu)選的真菌是酵母。所述酵母包括釀酒酵母和粟酒裂殖酵母。用于將包含編碼瘧原蟲GWT1蛋白的插入DNA的表達(dá)載體導(dǎo)入上述真菌細(xì)胞的方法是本領(lǐng)域技術(shù)人員所熟知的。
當(dāng)瘧原蟲GWT1蛋白在真菌細(xì)胞中表達(dá)時(shí)，轉(zhuǎn)運(yùn)到真菌細(xì)胞壁的GPI-錨定蛋白量可通過下述方法測(cè)定(1)利用報(bào)告酶的方法；(2)利用與真菌細(xì)胞壁表面糖蛋白反應(yīng)的抗體的方法；(3)利用該蛋白粘附動(dòng)物細(xì)胞的能力；或者(4)在光學(xué)顯微鏡或電子顯微鏡下觀察真菌細(xì)胞的方法。
(1)-(4)的方法已在WO 02/04626中公開，所述方法在該發(fā)明的實(shí)施例中進(jìn)行了詳細(xì)描述。利用(1)-(4)的方法，并且優(yōu)選(1)-(4)的方法的組合可以判斷試樣是否抑制GPI-錨定蛋白到細(xì)胞壁上的轉(zhuǎn)運(yùn)過程或者GPI-錨定蛋白在真菌細(xì)胞表面的表達(dá)。
在下文中，將描述方法(1)-(4)。
(1) 利用報(bào)告酶進(jìn)行的方法GPI-錨定蛋白到細(xì)胞壁的轉(zhuǎn)運(yùn)過程可通過示蹤實(shí)驗(yàn)定量如用放射性同位素標(biāo)記GPI-錨定蛋白，獲得真菌細(xì)胞壁級(jí)分，并用抗GPI-錨定蛋白的抗體進(jìn)行免疫沉淀反應(yīng)。也可以用另一種方法更簡(jiǎn)便地定量在各種GPI-錨定蛋白中常見的、被認(rèn)為起轉(zhuǎn)運(yùn)信號(hào)作用的C-末端序列可與便于測(cè)量的酶(報(bào)告酶)表達(dá)為融合蛋白，獲得真菌細(xì)胞壁級(jí)分；然后采用報(bào)告系統(tǒng)測(cè)量每一級(jí)分的酶活性(Van Berkel MAA等，F(xiàn)EBSLetters，349135-138，1994)。在下文中，將要會(huì)對(duì)一種采用報(bào)告酶進(jìn)行的方法進(jìn)行描述，但是本發(fā)明并不僅限于此。
首先，構(gòu)建報(bào)告基因并將其引入真菌中。報(bào)告基因是這樣構(gòu)建的使在真菌中起作用的啟動(dòng)子序列，以與閱讀框匹配的方式連接分別編碼信號(hào)序列、報(bào)告酶和GPI-錨定蛋白C-末端序列的DNA。啟動(dòng)予序列的實(shí)例包括GAL10及ENO1。信號(hào)序列的實(shí)例包括如α-因子，轉(zhuǎn)化酶，溶菌酶。報(bào)告酶的實(shí)例是β-內(nèi)酰胺酶，溶菌酶，堿性磷酸酶和β-半乳糖苷酶?？梢允褂靡子跈z出的綠色螢光蛋白(GFP)，即便它不具有酶活性。GPI-錨定蛋白C-末端序列包括α-凝集素(agglutinin)C-末端序列，CWP2 C-末端序列等。此外，優(yōu)選將適宜的選擇標(biāo)記物如LEU2和URA3插到包含所構(gòu)建的報(bào)告基因的載體中。
將所構(gòu)建的報(bào)告基因通過適宜的方法插到真菌中，如乙酸鋰法(Gietz D等，Nucl.Acids Res.201425，1992)。并且在需要時(shí)，利用適于選擇標(biāo)記物的方法(如適于LEU2的Leu-培養(yǎng)基，以及適于URA3的Ura-培養(yǎng)基)培養(yǎng)真菌，然后挑選其中引入了DNA的真菌。
通過下列方法測(cè)定試樣對(duì)GPI-錨定蛋白到細(xì)胞壁的轉(zhuǎn)運(yùn)過程的影響在試樣存在時(shí)，于適宜的條件下(如30℃48小時(shí))培養(yǎng)引入了報(bào)告基因的真菌。培養(yǎng)之后，離心培養(yǎng)物上清液，并測(cè)量培養(yǎng)物上清液級(jí)分的報(bào)告酶活性。洗滌所得細(xì)胞級(jí)分，然后通過適當(dāng)?shù)姆椒ǚ蛛x細(xì)胞壁成分，例如用葡聚糖酶降解細(xì)胞壁葡聚糖，然后測(cè)量細(xì)胞壁級(jí)分和細(xì)胞質(zhì)級(jí)分的報(bào)告酶活性。該試驗(yàn)可以如下簡(jiǎn)單地進(jìn)行離心確定細(xì)胞級(jí)分中報(bào)告酶的量，然后在不洗滌細(xì)胞的情況下按比例計(jì)算來(lái)源于培養(yǎng)物上清液級(jí)分但殘留在細(xì)胞級(jí)分中的報(bào)告酶的量，從細(xì)胞級(jí)分的報(bào)告酶的量中減去此量。
如果試樣顯示出增加培養(yǎng)物上清液級(jí)分中報(bào)告酶活性的活性(活性/細(xì)胞)，或者降低細(xì)胞壁級(jí)分中報(bào)告酶活性的活性(活性/細(xì)胞)，那么就可以判定該試樣對(duì)GPI-錨定蛋白到細(xì)胞壁的轉(zhuǎn)運(yùn)過程有影響。
(2) 采用與真菌細(xì)胞壁表面糖蛋白反應(yīng)的抗體的方法對(duì)于試樣影響GPI-錨定蛋白在真菌表面層的表達(dá)的能力，可以通過利用與真菌細(xì)胞壁中的GPI-錨定蛋白反應(yīng)的抗體進(jìn)行定量來(lái)測(cè)定。
抗體可以如下制備例如，可以由GPI-錨定蛋白的氨基酸序列預(yù)測(cè)抗原決定簇，所述GPI-錨定蛋白如α-凝集素，Cwp2p，或Als1p(Chen MH等，J.Biol.Chem.，27026168-26177，1995；Van Der Vaat JM等，J.Bacteriol.，1773104-3110，1995；Hoyer LL等，Mol.Microbiol.，1539-54，1995)，合成該區(qū)的肽，將其與抗原性物質(zhì)如載體蛋白結(jié)合，然后通過免疫兔子等得到多克隆抗體，或者通過免疫小鼠等得到單克隆抗體。優(yōu)選是針對(duì)Als1p肽的兔多克隆抗體。
在可供選擇的方法中，可以通過用真菌，優(yōu)選過量表達(dá)GPI-錨定蛋白，如α-凝集素，Cwp2p及Als1p的真菌免疫小鼠等獲得抗GPI-錨定蛋白的單克隆抗體，(在某些情況下，可以進(jìn)一步用部分純化的GPI-錨定蛋白進(jìn)行免疫)，并利用ELISA，Western印跡分析等以此制備抗體為基礎(chǔ)選出產(chǎn)生的克隆。
通過下述方法可以檢測(cè)試樣對(duì)GPI-錨定蛋白到細(xì)胞壁的轉(zhuǎn)運(yùn)過程的影響，以及試樣對(duì)來(lái)源于細(xì)胞壁中GPI-錨定蛋白的蛋白量的影響。
在試樣存在時(shí)，于適宜的條件下如30℃48小時(shí)培養(yǎng)真菌。通過離心收集所培養(yǎng)的真菌并將細(xì)胞破碎，優(yōu)選采用玻璃珠。優(yōu)選用SDS離心提取洗滌過的破碎細(xì)胞，然后洗滌沉淀物。提取之后，用降解葡聚糖的酶，優(yōu)選葡聚糖酶處理破碎的細(xì)胞，其經(jīng)離心處理的上清液即為GPI-錨定蛋白樣品。
將抗-Als1p肽的抗體經(jīng)4℃過夜溫育包被在96-孔板上。用洗滌溶液，優(yōu)選含0.05％Tween 20的PBS(PBST)洗滌板之后，用封閉96-孔板非特異性吸附位點(diǎn)的試劑，優(yōu)選蛋白如BSA或明膠蛋白，更優(yōu)選BlockAce(Dainippon Pharmaceutical Co.，Ltd.)進(jìn)行封閉。用洗滌溶液，優(yōu)選PBST，再次洗滌之后，加入適當(dāng)稀釋的GPI-錨定蛋白樣品。在室溫進(jìn)行適當(dāng)長(zhǎng)時(shí)間如2小時(shí)的反應(yīng)。用洗滌溶液，優(yōu)選PBST，洗滌之后，使針對(duì)酶標(biāo)記的白色念珠菌的抗體，優(yōu)選HRP-標(biāo)記的抗-念珠菌抗體，在室溫反應(yīng)適當(dāng)長(zhǎng)的時(shí)間如2小時(shí)。標(biāo)記方法可以是酶標(biāo)記法或放射性同位素標(biāo)記法。用洗滌溶液，優(yōu)選PBST，洗滌之后，通過適于標(biāo)記類型即酶標(biāo)記的方法計(jì)算GPI-錨定蛋白樣品中Als1p的量，加入底物溶液，然后在終止反應(yīng)時(shí)測(cè)量在490nm處的吸光度。
(3) 利用粘附動(dòng)物細(xì)胞的能力進(jìn)行的方法試樣對(duì)GPI-錨定蛋白在真菌表面的表達(dá)的影響可以通過測(cè)量真菌細(xì)胞壁中GPI-錨定蛋白的活性，優(yōu)選通過測(cè)量真菌對(duì)動(dòng)物細(xì)胞等的粘附能力來(lái)進(jìn)行測(cè)定。除了Als1p，Hwp1p等參與粘附動(dòng)物細(xì)胞的活性之外，GPI-錨定蛋白活性還包括α-凝集素參與交配的活性，F(xiàn)lo1p參與酵母聚集的活性等。在下文中，將詳細(xì)描述利用真菌對(duì)動(dòng)物細(xì)胞的粘附活性進(jìn)行的方法，但是本發(fā)明并不僅限于此。
使用對(duì)細(xì)胞具有粘附能力的真菌，優(yōu)選的真菌為白色念珠菌。對(duì)于哺乳動(dòng)物細(xì)胞采用粘附真菌的細(xì)胞，優(yōu)選小腸上皮細(xì)胞。培養(yǎng)哺乳動(dòng)物細(xì)胞并通過適當(dāng)?shù)姆椒?，如乙醇固定法將其固定。將試樣和真菌培養(yǎng)適當(dāng)長(zhǎng)的時(shí)間，如30℃溫育48小時(shí)，然后接種并培養(yǎng)一定長(zhǎng)的時(shí)間，如在30℃溫育1小時(shí)。移出培養(yǎng)物上清液，用緩沖液洗滌，加樣至瓊脂培養(yǎng)基，如Sabouraud Dextrose Agar培養(yǎng)基(Becton Dickinson Company，Ltd.)。30℃過夜培養(yǎng)后，計(jì)數(shù)菌落的數(shù)目，并計(jì)算粘附率。
如果與未經(jīng)該化合物處理的真菌相比，觀察到試樣具有使細(xì)胞粘附而形成的菌落數(shù)目降低的活性，則可以判定該試樣已經(jīng)影響了GPI-錨定蛋白到細(xì)胞壁的轉(zhuǎn)運(yùn)過程。
(4) 利用光學(xué)顯微鏡或電子顯微鏡觀察真菌的方法可以通過用電子顯微鏡觀察真菌細(xì)胞壁的結(jié)構(gòu)來(lái)確定試樣對(duì)GPI-錨定蛋白在真菌表面的表達(dá)的影響。
在試樣存在的條件下，將真菌如白色念珠菌培養(yǎng)一定長(zhǎng)的時(shí)間，如30℃培養(yǎng)48小時(shí)，用透射電子顯微鏡觀察其超微形態(tài)結(jié)構(gòu)。在此，利用透射電子顯微鏡進(jìn)行的觀察可以通過例如根據(jù)Electron Microscope Chart Manual(Medical Publishing Center)的方法來(lái)進(jìn)行。真菌細(xì)胞最外層的絮狀纖維結(jié)構(gòu)具有高電子密度，并且可通過透射電子顯微鏡觀察到。此結(jié)構(gòu)不受其它現(xiàn)有抗真菌劑的影響，并認(rèn)為是包括GPI-錨定蛋白作為其構(gòu)成成分的表面糖蛋白層。與未經(jīng)處理的細(xì)胞相比，當(dāng)此結(jié)構(gòu)消失，只留下具有高電子密度的微層時(shí)，可以判定所述試樣已經(jīng)影響了GPI-錨定蛋白到細(xì)胞壁的轉(zhuǎn)運(yùn)過程。
當(dāng)在透射電子顯微鏡以及光學(xué)顯微鏡下的觀察都顯示真菌細(xì)胞大量溶脹且出芽(分裂)受到抑制時(shí)，可以判定試樣對(duì)細(xì)胞壁有影響。
本發(fā)明還提供了治療瘧疾的方法，該方法包括施用抑制瘧原蟲GWT1蛋白的活性的化合物的步驟。所述化合物包括WO 02/04626中所述化合物(如本文(1)-(5)中所述化合物)。
天然PfGWT1蛋白的核苷酸序列的特點(diǎn)是具有非常高的AT含量(80.41％)，因此其密碼子使用是有偏好的(biased)。此外，所述基因包含在23個(gè)分離位置含六個(gè)或更多個(gè)連續(xù)A殘基的序列段，且這些序列段作為假(pseudo)-poly(A)位點(diǎn)來(lái)制備截短的蛋白。由于如上所述的特性，該基因只能少量地在酵母中表達(dá)，而且很難利用PCR進(jìn)行擴(kuò)增或者在大腸桿菌中進(jìn)行復(fù)制。也很難確定其核苷酸序列。然而，利用該DNA的簡(jiǎn)并突變體(SEQID NO5)，其AT含量低于編碼PfGWT1蛋白的DNA，本發(fā)明人成功地使PfGWT1蛋白高效表達(dá)。本發(fā)明人還揭示簡(jiǎn)并突變體DNA的引入能拯救GWT1-缺陷型酵母的表型。此項(xiàng)發(fā)現(xiàn)說(shuō)明瘧原蟲的GPI合酶與真菌如酵母的GPI合酶是可以互換的。
編碼瘧原蟲GPI合酶的基因的AT含量例如對(duì)于惡性瘧原蟲的GPI8為79.35％，對(duì)于惡性瘧原蟲的GPI13為77.89％。其AT含量與PfGWT1的AT含量一樣高。由于惡性瘧原蟲基因組翻譯區(qū)內(nèi)的平均AT含量為76.3％，可以推斷大多數(shù)惡性瘧原蟲基因幾乎不能在其它物種中表達(dá)。本發(fā)明人成功地使比編碼PfGWT1蛋白的DNA具有更低AT含量的DNA簡(jiǎn)并突變體在酵母中表達(dá)。因此，通過利用該簡(jiǎn)并DNA突變體，可以在瘧原蟲之外的宿主中表達(dá)瘧原蟲GPI合酶。此外，GPI-缺陷型酵母和GWT1-缺陷型酵母已知表現(xiàn)出相似的表型，包括致死性等特性。這樣，可以采用上述簡(jiǎn)并突變體DNA拯救GPI合酶基因-缺陷型真菌的表型。
已導(dǎo)入了上述簡(jiǎn)并突變體DNA的GPI合酶基因-缺陷型真菌的表型由瘧原蟲GPI合酶的活性來(lái)決定。相應(yīng)地，可以利用GPI合酶基因-缺陷型真菌的表型作為指標(biāo)，經(jīng)篩選選出抑制瘧原蟲GPI合酶活性的化合物。這樣，事實(shí)上并不需要利用瘧原蟲就能選出靶向GPI生物合成路徑的的抗瘧藥物。
本發(fā)明提供了編碼具有拯救GPI合酶基因-缺陷型真菌表型的活性的蛋白的簡(jiǎn)并突變體DNA，其比編碼參與GPI生物合成的天然DNA具有更低的AT含量。所述DNA可以在本發(fā)明的篩選方法中使用。
如本文所用，術(shù)語(yǔ)“AT含量”是指GPI合酶基因編碼區(qū)完整核苷酸序列中的腺嘌呤和胸腺嘧啶含量。本發(fā)明簡(jiǎn)并突變體DNA中的AT含量范圍優(yōu)選從50％到70％，更優(yōu)選從53％到65％，更加優(yōu)選從55％到62％。
GPI合酶基因-缺陷型真菌的表型包括溫度敏感性(優(yōu)選高溫敏感性)和致死性。
在瘧原蟲中參與GPI生物合成的本發(fā)明蛋白包括GWT1，GPI1，GPI8，GPI3/PIG-A，GPI10/PIG-B，YJR013 W/PIG-M，GPI13/PIG-O，GAA1/GAA-1，DPM1，GPI2，GPI15，YDR437W，GPI12，MCD4，GPI11，GPI7，GPI17，GPI16，CDC91，DPM2，DPM3和SL15。上述蛋白中，已知GPI1和GPI8存在于瘧原蟲中，GPI3/PIG-A，GPI10/PIG-B，YJR013W/PIG-M，GPI13/PIG-O，GAA1/GAA-1和DPM1也認(rèn)為存在于瘧原蟲中(Delorenzi等，Infect.Immun.704510-4522，2002)。惡性瘧原蟲GWT1，GPI1，GPI8，GPI3/PIG-A，GPI10/PIG-B，YJR013W/PIG-M，GPI13/PIG-O，GAA1/GAA-1和DPM1的核苷酸序列分別示于SEQ ID NO1和SEQ ID NOs6-21中的偶數(shù)序列鑒定號(hào)中。各相應(yīng)氨基酸序列示于SEQ ID NO2和SEQ ID NOs6-21中的奇數(shù)序列鑒定編號(hào)中。此外，間日瘧原蟲GWT1的核苷酸序列示于SEQ ID NO3，相應(yīng)的氨基酸序列示于SEQ ID NO4。采用本領(lǐng)域技術(shù)人員熟知的方法，如采用雜交或PCR，利用包含SEQ ID NO1和3，以及偶數(shù)號(hào)的SEQ ID NOs6-21中任一核苷酸序列的DNA，可以對(duì)其它瘧原蟲的GWT1，GPI1，GPI8，GPI3/PIG-A，GPI10/PIG-B，YJR013W/PIG-M，GPI13/PIG-O，GAA1/GAA-1或DPM1進(jìn)行克隆。
另外，利用酵母或人GPI合酶基因可以對(duì)瘧原蟲的除GWT1，GPI1，GPI8，GPI3/PIG-A，GPI10/PIG-B，YJR013W/PIG-M，GPI13/PIG-O，GAA1/GAA-1和DPM1之外的GPI合酶基因進(jìn)行克隆。酵母(釀酒酵母)GPI2，GPI15，YDR437W，GPI12，MCD4，GPI11，GPI7，GPI17，GPI16和CDC91的核苷酸序列分別示于SEQ ID NOs22-41中的偶數(shù)序列鑒定號(hào)中；各相應(yīng)氨基酸序列示于SEQ ID NOs22-41中的奇數(shù)序列鑒定號(hào)中。此外，人DPM2，DPM3和SL1 5的核苷酸序列分別示于SEQ ID NOs42-47中的偶數(shù)序列鑒定號(hào)中；各相應(yīng)氨基酸序列示于SEQ ID NOs42-47中的奇數(shù)序列鑒定號(hào)中。
編碼參與瘧原蟲GPI生物合成的蛋白的簡(jiǎn)并突變體DNA的制備由兩步組成設(shè)計(jì)和合成，所述簡(jiǎn)并突變體DNA的AT含量比天然DNA低。在設(shè)計(jì)步驟中，首先對(duì)目的蛋白的氨基酸序列進(jìn)行反向翻譯，然后列出各氨基酸殘基的可能密碼子。反向翻譯可以利用商購(gòu)基因分析軟件(例如DNASIS-Pro；Hitachi Software Engineering Co.，Ltd)來(lái)實(shí)現(xiàn)。在列出的密碼子中，為各個(gè)氨基酸選出符合目的的密碼子(例如，AT含量較低的密碼子和在用于基因表達(dá)的宿主中使用的常規(guī)密碼子)。簡(jiǎn)并突變體DNA可以通過利用這些選出的密碼子重排目的蛋白的氨基酸序列來(lái)對(duì)其進(jìn)行設(shè)計(jì)。
如此設(shè)計(jì)的DNA可以通過本領(lǐng)域技術(shù)人員所熟知的方法來(lái)進(jìn)行合成。本發(fā)明的簡(jiǎn)并突變體DNA可以基于設(shè)計(jì)的核苷酸序列，通過如利用商購(gòu)DNA合成儀來(lái)進(jìn)行合成。
本發(fā)明還提供了插入了上述簡(jiǎn)并突變體DNA的載體，以及在可表達(dá)狀態(tài)包含該DNA或該載體的轉(zhuǎn)化體(優(yōu)選GPI合酶基因-缺陷型真菌)。載體和宿主可以是前面所述的載體和宿主。
如本文所用，表達(dá)“GPI合酶基因缺陷”是指該基因的功能產(chǎn)物未表達(dá)或表達(dá)水平減少。本發(fā)明的GPI合酶基因-缺陷型真菌可通過破壞GPI基因來(lái)加以制備。破壞可以通過在同源重組技術(shù)等的基礎(chǔ)上嵌入與該基因無(wú)關(guān)的DNA如選擇標(biāo)記來(lái)實(shí)現(xiàn)。更具體的說(shuō)，所述突變型真菌可通過將選擇標(biāo)記盒導(dǎo)入酵母，該選擇標(biāo)記盒含有利用引物擴(kuò)增的粟酒裂殖酵母his5基因或卡那霉素抗性基因(Longtine等，Yeast，14953-961，1998)，其均含有與部分該基因(50-70個(gè)核苷酸)同源的核苷酸序列。
本發(fā)明的GPI合酶基因-缺陷型真菌包括，如GWT1溫度敏感突變株gwt1-20，GPI7破壞菌株，GPI8突變株gpi8-1，以及GPI10溫度敏感突變株per13-1。
轉(zhuǎn)化了本發(fā)明簡(jiǎn)并突變體DNA的GPI合酶基因-缺陷型真菌可以通過將插入了該簡(jiǎn)并突變體DNA的載體導(dǎo)入真菌中來(lái)進(jìn)行制備。pRS316，YEp351等可用作釀酒酵母的載體，pcL，pALSK等可用作粟酒裂殖酵母的載體。
本發(fā)明還提供了篩選抗瘧藥物的方法，該方法包括利用上述GPI合酶基因-缺陷型真菌。
在該方法中，第一步包括將試樣與GPI合酶基因-缺陷型真菌接觸，其中所述真菌轉(zhuǎn)化了比參與瘧原蟲GPI生物合成的蛋白的編碼DNA具有更低AT含量的簡(jiǎn)并突變體DNA。所述“接觸”可通過將試樣加到上述真菌培養(yǎng)物中來(lái)實(shí)現(xiàn)。當(dāng)試樣是蛋白時(shí)，可以將包含該蛋白的編碼DNA的載體導(dǎo)入上述真菌中。
在本發(fā)明的方法中，下一步包括測(cè)量上述真菌的生長(zhǎng)程度。更具體地說(shuō)，在常規(guī)培養(yǎng)條件下接種真菌，具體地，將真菌接種至液體培養(yǎng)基，如酵母提取物聚蛋白胨葡萄糖培養(yǎng)基(YPD培養(yǎng)基)或瓊脂平板上，然后在25-37℃溫育4-72小時(shí)。這樣，就可以對(duì)已轉(zhuǎn)化本發(fā)明簡(jiǎn)并突變體DNA的GPI合酶基因-缺陷型真菌進(jìn)行生長(zhǎng)評(píng)估。生長(zhǎng)程度還可以以培養(yǎng)基液體的混濁度，菌落數(shù)量，或者瓊脂平板上形成的斑點(diǎn)大小或顏色作為指標(biāo)來(lái)進(jìn)行測(cè)定。在本發(fā)明的方法中，下一步包括選出抑制上述真菌生長(zhǎng)的化合物。
在另一可選的方法中，第一步包括將試樣與GPI合酶基因-缺陷型真菌接觸，其中該真菌已導(dǎo)入了上述簡(jiǎn)并突變體DNA。下一步包括測(cè)定轉(zhuǎn)運(yùn)到酵母細(xì)胞壁上的GPI-錨定蛋白量。該檢測(cè)方法包括(1)利用報(bào)告酶的方法；(2)利用與真菌細(xì)胞壁表面糖蛋白反應(yīng)的抗體的方法；(3)利用粘附動(dòng)物細(xì)胞的能力的方法；和(4)利用光學(xué)顯微鏡或電子顯微鏡觀察真菌的方法。在本發(fā)明的方法中，下一步包括選出降低轉(zhuǎn)運(yùn)到細(xì)胞壁的GPI-錨定蛋白量的樣品。
本發(fā)明提供了利用參與GPI生物合成的蛋白篩選抗瘧藥物的方法，該蛋白是利用本發(fā)明的簡(jiǎn)并突變體DNA制得的。所述方法包括例如結(jié)合分析系統(tǒng)，在該系統(tǒng)中進(jìn)行篩選是為了選出結(jié)合參與GPI生物合成的蛋白的化合物，該化合物與結(jié)合所述蛋白的標(biāo)記化合物競(jìng)爭(zhēng)。具體地說(shuō)，將本發(fā)明的簡(jiǎn)并突變體DNA導(dǎo)入GPI合酶基因-缺陷型真菌中，在該真菌中表達(dá)該DNA編碼的蛋白，獲得所表達(dá)的蛋白。然后，將制得的蛋白與試樣和能結(jié)合該蛋白的標(biāo)記化合物接觸。在下一步中，檢測(cè)結(jié)合該蛋白的標(biāo)記化合物，選出降低結(jié)合該蛋白的標(biāo)記化合物量的試樣。
本發(fā)明還提供了GlcN-PI酰基轉(zhuǎn)移酶分析系統(tǒng)。該系統(tǒng)包括使用GWT1蛋白，該蛋白是利用編碼具有補(bǔ)償GWT1-缺陷型酵母表型的活性的蛋白的DNA制得的，其中所述DNA是編碼瘧原蟲GWT1蛋白的DNA簡(jiǎn)并突變體，它比天然DNA具有更低的AT含量。具體地，將簡(jiǎn)并突變體DNA導(dǎo)入GWT1-缺陷型真菌，在該真菌中表達(dá)該簡(jiǎn)并突變體DNA編碼的蛋白，獲得所表達(dá)的蛋白。然后，將此蛋白與試樣接觸，檢測(cè)GlcN-(?；?PI，選出降低GlcN-(?；?PI量的試樣。

附圖的簡(jiǎn)單說(shuō)明

圖1顯示四分體分析結(jié)果的照片。在導(dǎo)入了opfGWT1-過表達(dá)質(zhì)粒后，gwt1遭破壞的菌株存活。將衍生自單個(gè)雙倍體細(xì)胞的四個(gè)孢子垂直點(diǎn)樣。
如果一個(gè)拷貝的GWT1基因被破壞，則僅有一半的孢子生長(zhǎng)。在這種情況下，[菌落-形成的斑點(diǎn)]∶[未顯示生長(zhǎng)的斑點(diǎn)]的比率為2∶2。在用箭頭標(biāo)記的縱列中，gwt1破壞體(disruptant)的致死表型由于導(dǎo)入了opfGWT1而得到補(bǔ)償，因此4個(gè)斑點(diǎn)全部生長(zhǎng)，均形成菌落。
圖2的圖表顯示化合物對(duì)于表達(dá)opfGWT1基因的酵母生長(zhǎng)的抑制活性。在GWT1基因遭破壞的酵母中表達(dá)酵母GWT1基因或opfGWT1基因。
具有抑制酵母GWT1-依賴性生長(zhǎng)活性的化合物也顯示了對(duì)于酵母的opfGWT1-依賴性生長(zhǎng)的抑制活性，其中opfGWT1在該酵母中表達(dá)。
圖3是顯示抗瘧活性的圖表。用惡性瘧原蟲感染人紅細(xì)胞。將GWT1-抑制性化合物加至這些紅細(xì)胞中，并確定對(duì)瘧原蟲感染的抑制。

實(shí)施本發(fā)明的最佳方式下面，將利用實(shí)施例詳細(xì)地描述本發(fā)明，但是本發(fā)明并不限于此。
惡性瘧原蟲GWT1(PfGWT1)(1)惡性瘧原蟲GWT1(PfGWT1)的核苷酸序列(SEQ ID NO1)已公開于惡性瘧原蟲基因組數(shù)據(jù)庫(kù)(PlasmoDB database，http://plasmodb.org/)中。用純化自惡性瘧原蟲(3D7菌株)的基因組DNA作為模板，通過PCR克隆PfGWT1基因。將PfGWT1基因的5和3’兩部分分別制備，并在XbaI(TCTAGA)限制酶位點(diǎn)對(duì)兩部分進(jìn)行組裝。這樣，就制得全長(zhǎng)PfGWT1基因。另外，在編碼區(qū)外的限制酶位點(diǎn)也包含在其中，從而可以插入到表達(dá)載體內(nèi)。
(2)用惡性瘧原蟲基因組DNA作為模板，以及引物pf152F(SEQ ID NO48)和pf136R(SEQ ID NO49)，通過PCR擴(kuò)增PfGWT1基因的5’部分。用pf137F(SEQ ID NO50)和pf151R(SEQ ID NO51)作為引物，通過上述相同的方法，擴(kuò)增PfGWT1基因的3’部分。將擴(kuò)增出的DNA片斷亞克隆到pT7-Blue載體(Novagen)中，對(duì)插入子的核苷酸序列進(jìn)行測(cè)序，以確定其與SEQ ID NO1的同源性。含有PfGWT1基因5’部分的克隆命名為PF15-5克隆。含有PfGWT1基因3’部分的克隆命名為PF20-9克隆。
(3)利用PCR將限制酶的切割位點(diǎn)添加到編碼區(qū)的外側(cè)，從而可以使PfGWT1基因插到表達(dá)載體內(nèi)。用PF15-5作為模板，以及引物pf154FE(SEQID NO52)和pf157R(SEQ ID NO53)，通過PCR將EcoRI切割位點(diǎn)加至5’部分。將擴(kuò)增的DNA片斷亞克隆到pT7-Blue載體(Novagen)中，制得pT7-plasmN2克隆。同樣地，用PF20-9作為模板，以及引物pf168BK(SEQID NO54)和pf155RK(SEQ ID NO55)，通過PCR擴(kuò)增3’部分。對(duì)擴(kuò)增的DNA片斷進(jìn)行亞克隆，制得pT7-plasmBK5克隆。
(4)用下述方法制備全長(zhǎng)PfGWT1基因。用限制性內(nèi)切酶EcoRI和KpnI消化酵母表達(dá)載體YEp352GAPII。將來(lái)源于pT7-plasmN2的EcoRI-XbaI片斷(約1500bp)，和來(lái)源于pT7-plasmBK5的XbaI-KpnI片斷(約1100bp)插入載體的切割位點(diǎn)。這樣，就構(gòu)建成了包含全長(zhǎng)PfGWT1的表達(dá)載體YEp352GAPII-PfGWT1。

在惡性瘧原蟲GWT1(PfGWT1)核苷酸序列(SEQ ID NO1)的基礎(chǔ)上進(jìn)行密碼子取代，所述核苷酸序列已在惡性瘧原蟲基因組數(shù)據(jù)庫(kù)(PlasmoDBdatabase，http://plasmodb.org/)中公開。將所得核苷酸序列命名為“優(yōu)化的PfGWT1(opfGWT1)”(SEQ ID NO5)。
將上述序列設(shè)計(jì)為編碼區(qū)外包含額外的序列；即EcoRI切割位點(diǎn)序列(GAATTC，5’末端)，Kozak序列(ACC，3’末端)，和KpnI切割位點(diǎn)序列(GGTACC，3’末端)。所得序列的合成委托美國(guó)的Blue Heron Inc。用這些額外的限制酶位點(diǎn)將完全合成的opfGWT1與YEp352GAPII載體連接，從而構(gòu)建opfGWT1的過表達(dá)質(zhì)粒。將該構(gòu)建體引入僅僅單個(gè)GWT1基因拷貝被破壞的二倍體細(xì)胞(WDG2)中。在含孢子形成培養(yǎng)基的平板上培養(yǎng)獲得的轉(zhuǎn)化體，形成用于四分體分析的孢子。
新設(shè)計(jì)的密碼子-修飾opfGWT1的AT含量減少至61.55％。四分體分析結(jié)果示于圖1。在導(dǎo)入opfGWT1過表達(dá)質(zhì)粒后，gwt1遭破壞的菌株存活。上述發(fā)現(xiàn)表明在通過密碼子修飾而使AT含量降低時(shí)，PfGWT1基因可以在酵母細(xì)胞中表達(dá)。
利用opfGWT1-表達(dá)型酵母進(jìn)行抗瘧活性分析利用opfGWT1-表達(dá)型酵母構(gòu)建抗瘧活性化合物的篩選系統(tǒng)。
通過將釀酒酵母GWT1終止子，釀酒酵母GAPDH啟動(dòng)子以及多克隆位點(diǎn)插到單拷貝載體pRS316的SacI-KpnI位點(diǎn)來(lái)構(gòu)建表達(dá)盒。分別將釀酒酵母GWT1和opfGWT1插到多克隆位點(diǎn)，制備pGAP-ScGWT1和pGAP-opfGWT1質(zhì)粒。將這些質(zhì)粒導(dǎo)入GWT1破壞體。用YPAD連續(xù)的兩倍稀釋化合物(1)，使其最高的終濃度為50μg/ml。將稀釋化合物的50μl等分試樣加到96-孔板的每個(gè)孔中。將含有各種質(zhì)粒的酵母細(xì)胞過夜培養(yǎng)物稀釋1000倍，然后將稀釋物的50μl等分試樣加到各孔中。將平板在30℃溫育2天，然后在660nm測(cè)定培養(yǎng)物混濁度(圖2和表1)[表1]

抗瘧活性利用紅細(xì)胞培養(yǎng)系統(tǒng)，對(duì)抑制酵母GWT1的典型化合物(1)-(5)進(jìn)行抗瘧活性分析。

化合物(1)1-(4-丁基芐基)異喹啉

化合物(2)4-[4-(1-異喹啉基甲基)苯基]-3-丁炔-1-醇

化合物(3)5-丁基-2-(1-異喹啉基甲基)苯酚
化合物(4)2-(4-溴-2-氟芐基)-3-甲氧基吡啶 化合物(5)N-[2-(4-丁基芐基)-3-吡啶基]-N-甲胺具體地說(shuō)，將待測(cè)化合物溶解在100％DMSO中，用培養(yǎng)基稀釋，然后將稀釋物的80μl等分試樣加到96-孔培養(yǎng)板的每個(gè)孔中。惡性瘧原蟲FCR3菌株在37℃用含10％人血清的RPMI1640培養(yǎng)基預(yù)培養(yǎng)，然后在每個(gè)孔中加入20μl的培養(yǎng)細(xì)胞(含1 0％紅細(xì)胞)。此時(shí)，0.47％的紅細(xì)胞被感染。在5％O2，5％CO2，和90％N2的37℃條件培養(yǎng)48小時(shí)后，將瘧原蟲用吉姆薩(Giemsa)染色法染色。測(cè)定原蟲-感染的紅細(xì)胞數(shù)量，以估計(jì)感染率(圖3)。結(jié)果，顯示化合物(3)具有很強(qiáng)的抗瘧活性。其它4種化合物也顯示了抗瘧活性?；衔?4)表現(xiàn)的活性最低。這樣，抑制酵母GWT1的化合物包括具有抑制惡性瘧原蟲GWT1活性的化合物，這說(shuō)明抗瘧藥物可以在這些化合物的基礎(chǔ)上進(jìn)行合成。
工業(yè)實(shí)用性本發(fā)明成功地制得能表達(dá)瘧原蟲GWT1的真菌。采用該真菌，而不采用瘧原蟲，能篩選出靶向GPI生物合成途徑的抗瘧藥物。
到目前為止，還從未進(jìn)行過在真菌細(xì)胞中表達(dá)瘧原蟲基因以及篩選抑制該基因功能的物質(zhì)的嘗試。本發(fā)明的方法并不需要利用瘧原蟲，因此本方法證明了在后基因組時(shí)代，采用比較基因組進(jìn)行用于藥物發(fā)現(xiàn)的全新篩選方法的可能性。
