Description
技术领域:
本发明涉及利用基因工程技术改造制备抗生素的新衍生物,具体而言,涉及利用基因工程技术获得格尔德霉素新衍生物4,5双氢噻嗪酮格尔德霉素及其制备方法和应用。
技术背景:
吸水链霉菌17997(Streptomyces hygrocopicus 17997)是中国医学科学院医药生物技术研究所从我国土壤中分离到的,经鉴定其可以产生格尔德霉素(geldanamycin,Gdm)。Gdm具有抗原虫、抗肿瘤、抗病毒以及免疫调节等多种生物学活性[Sasaki K et al.J Antibiot(Tokyo)1979,32(8):849-51];[中国专利ZL97100523.0];[陶佩珍等,中国抗生素杂志,1997,22:368-372]。根据最近报道,Gdm还具有调节上皮氮氧合酶活性以及抗炎等作用[Murphy P et al.Journal ofNcuroscience Research,2002,67(4):461-470]。研究证明,格尔德霉素的特异性作用靶点是热休克蛋白90(heat shock protein 90,Hsp90)。Hsp90是许多信号蛋白的伴侣分子,Gdm通过对Hsp90的抑制,可以间接影响细胞内信号蛋白的功能,因此,有望成为一种颇具潜力的抗肿瘤和抗病毒药物。但是Gdm还存在毒性大及水溶性差等缺点,水溶性差会影响其生物利用度。这些缺陷限制了其开发成为有效药物。所以,寻找一种毒性低、水溶性好的衍生物,已成为其深入研究的主要目标。目前,已有两个在C17位进行取代的Gdm衍生物17-AAG和17-DMAG,相继在美国进行II期和I期临床试验[Goetz MP et al J Clin Oncol,2005,23(6):1078-1087];[Glaze ER et al.,Cancer Chemother Pharmacol.2005,56(6):637-647]。
Gdm的生物合成,是以3-氨基-5-羟基苯甲酸为起始物,2C单位为延伸单位,包括1个丙二酰,4个甲基丙二酰和2个甲氧基丙二酰,在荷载域和7个聚酮合酶(polyketide synthase,PKS)模块,顺序进行碳链的延伸反应形成聚酮链骨架,再经过酰胺合酶的环化,形成格尔德霉素前体-原Gdm(ProGdm)。继而通过后修饰过程,包括:C17位的羟基化及氧甲基化、C21位的氧化、C7位的氨甲酰 基化和C4,5位的氧化,最终形成Gdm。为了实现对Gdm生物学方法的改造,本实验室从Streptomyces hygroscopicus 17997基因文库中克隆了与Gdm生物合成相关的基因簇[高群杰等,中国抗生素杂志,2002,27(1):13-27];[赫卫清,王以光,中国生物工程学报,2006,22:902-906]。本发明通过阻断吸水链霉菌17997中格尔德霉素生物合成基因-P450单加氧酶基因(gdmP)的方法,获得一种新的格尔德霉素衍生物4,5-双氢噻嗪酮格尔德霉素(4,5-dihydro-thiazinogeldanamycin)。4,5-双氢噻嗪酮格尔德霉素具抗病毒活性,其水溶性比Gdm提高了33倍。本发明所述通过基因工程技术获得的Gdm新衍生物及其制备方法,为制备水溶性好的Gdm衍生物提供了新的途径。
利用生物学方法获得4,5-双氢噻嗪酮格尔德霉素的研究,迄今为止,尚未见有国内外的相关报道。
发明内容:
本发明提供了4,5双氢噻嗪酮格尔德霉素新化合物,其结构如式(1)所示:
本发明还提供了制备4,5双氢噻嗪酮格尔德霉素新化合物的方法,具体步骤依次为:
1、P450单加氧酶基因(gdmP)阻断变株的构建
采用大肠杆菌和链霉菌的穿梭载体构建基因阻断载体,以吸水链霉菌17997基因组为模板进行PCR,分别获得与gdmP基因同源的两个片段,在其中间以相应的酶切位点插入选择性标记如卡那霉素(kanamycin,Km)抗性基因,并与穿梭载体进行连接,转化大肠杆菌DH5α,获得用于目的基因阻断的重组载体;
通过接合转移,将重组载体导入吸水链霉菌17997中,获得接合转移子进行传 代培养,利用PCR方法鉴定确认gdmP基因阻断变株;
2、4,5双氢噻嗪酮格尔德霉素新化合物的发酵、提取
将gdmP基因阻断变株进行发酵培养,用等量乙酸乙酯萃取发酵液上清,乙酸乙酯萃取液经薄膜浓缩获得粗品,以TLC或HPLC进行检测,通过硅胶柱初步分离目的产物,再经制备型HPLC获得纯品。
3、4,5双氢噻嗪酮格尔德霉素的结构鉴定
经高分辨质谱确定4,5双氢噻嗪酮格尔德霉素分子量和分子式,经元素分析并通过HRFAB-MS、1H-NMR and 13C-NMR的解析,确定其结构。
本发明还提供了4,5双氢噻嗪酮格尔德霉素的生物活性试验,具体采用疱疹病毒HSV-1感染猴肾细胞,实验以Gdm为对照,评价了4,5双氢噻嗪酮格尔德霉素的抗病毒活性,结果表明,4,5双氢噻嗪酮格尔德霉素具有抗病毒活性。
本发明以光吸收值为基准,建立了4,5双氢噻嗪酮格尔德霉素浓度标准曲线,测定了其在水中的溶解度,并与Gdm进行了比较。
发明效果:
本发明通过同源基因双交换阻断技术,破坏吸水链霉菌17997中的格尔德霉素生物合成基因gdmP,在其变株发酵液中获得了Gdm新衍生物4,5双氢噻嗪酮格尔德霉素,所说衍生物不仅具有抗病毒活性,且水溶性比格尔德霉素提高33倍,显示其可望开发成为临床有应用前景的药物。

实施方案:
以下所列实施例是为帮助本领域技术人员更好地理解本发明,但不以任何方式限制本发明。
<实施例1>gdmP基因阻断重组载体的构建
根据gdm基因序列(Genbank DQ914285)设计引物(P1-P4),提取吸水链霉菌17997(中国微生物菌种保藏委员会药学微生物菌种保藏中心,保藏号CPHCC200178)基因组DNA,以此作为模板进行常规PCR。在本实验中,设计采用但不限于以下的引物序列和酶切位点:
上游引物(P1):5’-CCGGAATTCCGACGAGCGAGGGCACTTT-3’,带有EcoRI酶切位点;
下游引物(P2):5’-CGGGGTACCCGAGACCACGGCCAACATG-3’,带有KpnI酶切位点;扩增1031bp片段1。
上游引物(P3):5’-AAAACTGCAGGCCGTTGAGGCTGGAGTT-3’,带有PstI酶切位点;
下游引物(P4):5’-CTAGTCTAGAGGTATCTGCGTTACTGGGTG-3’,带有XbaI酶切位点;扩增1236bp片段2。
回收PCR产物片段1和2,在其中间插入选择性标记,如以kpnI-PstI酶切位点插入Km抗性基因,其来源于质粒载体pUC119[李开等微生物学报2007,47(2):191-196],并以EcoRI-XbaI酶切位点与携带硫链丝菌素抗性的pGH112载体[莫宏波等,生物工程学报,2004;20:662-666]相应酶切位点进行连接。连接产物转化大肠杆菌DH5α,提取转化子DNA,经酶切证明,获得基因阻断重组载体pGHEXP(图1)。
<实施例2>gdmP阻断变株的构建及鉴定
gdmP变株的筛选按照文献[赫卫清等中国抗生素杂志,2006,31(3):168-171]进行。将构建的基因阻断重组载体pGHEXP,通过能与吸水链霉菌进行接合转移的大肠杆菌E.coil ET12567/pUZ8002[Kieser T.et al.practical Streptomycesgenetics.Norwich:John Innes Foundation.2000]导入到吸水链霉菌17997中,并在MY培养基[赫卫清等中国抗生素杂志,2006,31(3):168-171]中传3~4代后,再进行单克隆分离,筛选获得KmR、TsrS的gdmP变株。对gdmP变株在基因整合水平进行PCR验证。以原株和变株的基因组为模板,选取gdmP基因两翼外测序列设计引物P5和P6(图1)进行PCR。结果表明,使用引物P5和P6原株基因组PCR产物大小约3.3kb左右,而在变株中扩增出将近3.7kb特异性条带(0.8kb的Km片段置换下0.4kb左右的gdmP基因)(图2)。
P5上游引物:5’-CCCTCGGGCAGATTCAC-3,
P6下游引物:5’-GTCGCACTCCAACCATTTC-3,
PCR结果揭示,在同源基因片段之间,插入了0.8kb左右的Km抗性基因,符合预期结果。gdmP变株在不加药连续传代中,Km抗性表型很稳定,说明该变株中确实发生了DNA同源重组双交换所造成的Km抗性基因插入,并使gdmP基因受到破坏。
<实施例3> 4,5双氢噻嗪酮格尔德霉素的制备
gdmP变株在MY固体培养基(酵母粉0.4%,麦芽提取物1.0%,葡萄糖0.4%,琼脂粉1.5%。并加入卡那霉素至终浓度50μg/ml))上培养7天,接种种子培养基(葡萄糖0.5%,酵母提取物0.4%,玉米浆0.5%,棉子饼粉0.25%,KH2PO4 0.05%,MgSO40.05%,CaCO3 0.3%)50ml于250ml三角瓶,28℃摇床200rpm振荡培养2天,以5-10%接种量转种发酵培养基(淀粉2%,棉子饼粉0.5%,葡萄糖0.5%,玉米浆1.0%,酵母粉0.5%,CaCO3 0.2%)50ml(500ml三角瓶)或1000ml(5000ml)28℃摇床200rpm振荡培养3天[赫卫清等中国抗生素杂志,2006,31(3):168-171]。发酵液过滤后,用滤液二分之一体积的乙酸乙酯提取,薄膜浓缩后上硅胶柱,以二氯甲烷∶甲醇19∶1进行洗脱,分部收集洗脱液,用岛津LC-10Avp高压液相色谱仪,SPD-M10AvP二极管阵列检测器,CLASS-VP工作站,以254nm进行HPLC检测(图3),汇总含4,5双氢噻嗪酮格尔德霉素化合物部分洗脱液,浓缩 后用制备型HPLC,ODS-C18柱(柱体积150×20毫米),甲醇∶水9∶11(v/v),流量每分钟5毫升,获得4,5双氢噻嗪酮格尔德霉素纯品。
<实施例4>4,5双氢噻嗪酮格尔德霉素结构的确定
ESI-MS给出该新化合物的分子量为635[(M+Na)+为658;(M+K)+为674];硫元素测试实验确证,该化合物含硫为4.65%,理论计算值为5.04%,误差主要是由于一般样品含有结晶水造成的影响,可以确定该化合物含有一个硫原子;HR-ESIMS给出的精确分子量为658.2963(含钠,理论计算值为635.2877)(图4),初步确定其分子式为C31H43N3O9SNa,较4,5双氢-GDM多出C2H3ONS部分。本发明分别用d6-DMSO和CD3OD作为溶剂,进行NMR测试[NMR数据见表1,图谱见图5、6(CD3OD)]。综合分析获得的NMR谱图,发现该化合物的结构较4,5-双氢GDM变化只发生在苯醌环上,多出2个碳原子的C22和C23化学位移值分别为30.50ppm和166.85ppm。C18和C21的化学位移有通常的184.02ppm和184.87ppm明显位移至高场,分别为120.67和150.08;亚甲基蓝显色反应提示该化合物含有酚羟基,初步推测C21由原来的羰基变成了羟基。在HMBC谱上,C22上的两个氢原子(δH 3.21/3.45)与C19和C23存在明显相关性;同时,一个重要的活泼氢信号(δH 9.51)与C22、C23,C18、C17和C19存在相关性;综合以上信息,可以断定,C19和一个S原子直接相连,而C21则与一个N原子直接相连,这两者之间形成了一个噻嗪酮环,所以,该新化合物的结构式为4,5双氢噻嗪酮格尔德霉素。

<实施例6>4,5双氢噻嗪酮格尔德霉素的水溶性测定
先准确称取一定量4,5双氢噻嗪格尔德霉素或对照格尔德霉素,分别溶解于甲醇,用甲醇进行系列稀释,分别测定其在OD251及OD304光吸收值,建立4,5双氢噻嗪酮格尔德霉素或格尔德霉素浓度与光吸收值的标准曲线。称取过量4,5双氢噻嗪酮格尔德霉素或对照格尔德霉素在pH7.0的磷酸缓冲液中避光搅拌过夜12h,然后离心10,000g 10min.。采用BECKMAN DU 800核酸/蛋白分析仪测定4,5双氢噻嗪酮格尔德霉素OD251或格尔德霉素OD304值。根据标准曲线测定磷酸缓冲液饱和液中两者的浓度。4,5双氢噻嗪格尔德霉素在水中的溶解度为0.573(mg/ml),非常明显高于格尔德霉素,结果见表2。
