Abstract
本发明请求保护制备胰岛素-低聚物缀合物IN-105的方法。具有式G-A-V-G-R-[B-链]-R-D-A-D-D-R-[A-链]的IN-105前体被在毕赤氏酵母中克隆并表达。该生物合成的前体随后与活化的低聚物缀合。然后用蛋白酶处理该IN-105前体-低聚物缀合物,并纯化以得到式为胰岛素-OC-CH2-CH2-(OCH2CH2)3-OCH3的活性胰岛素-低聚物缀合物。
Description
发明领域
本发明涉及一种制备式胰岛素-低聚物的胰岛素-低聚物缀合物的方法。该方法涉及式为G-A-V-R-[B-链]-R-DA-D-D-R-[A-链]的前体IP-F的克隆和表达,并将该表达的生物合成的前体与激活的低聚物缀合,随后用蛋白酶处理,并纯化以得到活性胰岛素-低聚物缀合物。
发明背景
胰岛β细胞分泌胰岛素的单链前体,称为胰岛素原,其经蛋白酶解后,导致形成具有生物活性的多肽胰岛素。该胰岛素分子在各物种中高度保守,且通常由两个经二硫键连接的氨基酸链组成。天然的人胰岛素分子(mw5,807道尔顿)具有A链和B链,A链具有21个氨基酸残基,甘氨酸位于氨基末端;B链具有30个氨基酸残基,苯丙氨酸位于氨基末端。胰岛素可以作为单体存在或者聚集成二聚体,或由三个二聚体形成的六聚体。单体能够结合受体,且是生物活性形式。
胰岛素多肽是负责控制葡萄糖在身体内转运、利用和存储的主要激素。胰岛素产生不足或受体对胰岛素的敏感性降低造成的碳水化合物代谢缺陷导致生物学病症糖尿病。糖尿病损害了利用葡萄糖的正常能力,结果提高血糖水平(高血糖症)。当葡萄糖在血液中积累时,尿中排泄过度水平的糖(糖尿)。糖尿病的其他症状包括尿量和频率增加、口渴、搔痒、饥饿、体重减轻和虚弱。糖尿病若不经治疗则导致酮病,随后是伴有恶心和呕吐的酸中毒。随着有害产物继续累积,患者会陷入糖尿病性昏迷,其导致患者死亡。有两种类型的糖尿病。I型是胰岛素依赖性糖尿病或IDDM。IDDM从前被称为“青少年糖尿病”。在IDDM中,胰不分泌胰岛素,且必须从外部来源提供胰岛素。尽管在一些晚期病例中需要胰岛素,但是II型或成年型糖尿病通常可通过饮食进行控制。
传统上几乎独有地使用牛和猪的胰岛素治疗人类糖尿病。随着重组技术的发展,可能通过发酵来商业规模生产人类胰岛素。另外,还开发了与天然人类胰岛素生物活性相当的基因工程改造的胰岛素类似物,以抗击糖尿病。但是,糖尿病的治疗方法通常需要定期注射胰岛素。由于胰岛素注射会不方便,因此已经尝试了各种方法以将胰岛素配制成通过非注射途径施用。这些公开物的名单包括:US4,338,306(Kitao等)报道了胰岛素和具有8-14个碳原子的脂肪酸及其无毒盐的药物组合物,用于胰岛素的直肠施用;US4,579,730(Kidron等)报道了一种含有胆汁酸或其碱金属盐的用于胰岛素经口施用的肠衣(enterocoated)胰岛素组合物;US5,283,236(Chiou等)报道了胰岛素组合物,其具有渗透增强剂以有助于较高分子量多肽的全身吸收,以及肽酶抑制剂用于通过眼全身送递胰岛素,其中该药物进入鼻泪管且被吸收到循环中;US5,658,878(Backstrom等)报道了胰岛素和碳链长度为10(即癸酸钠)、12(月桂酸钠)或14(肉豆蔻酸钠)的饱和脂肪酸的钠盐,其能增强胰岛素在下呼吸道中的吸收;US5,853,748(New等)报道了一种胰岛素、胆汁盐或胆汁酸和碳酸盐或碳酸氢盐离子的包有肠溶衣的组合物,用于调节消化道的pH为pH7.5到9以用于经口施用胰岛素。US6,200,602(Watts等)报道了胰岛素与吸收促进剂的用于结肠送递的胰岛素药物送递组合物,所述吸收促进剂包含连同分散剂一起的具有6到16个碳原子的脂肪酸和其盐的混合物,或中链脂肪酸的甘油单酯/甘油二酯的混合物,包在包衣中以防止该片剂、胶囊或丸剂到达近侧结肠前胰岛素和吸收促进剂的释放。
从文献中可以发现几种通过经口施用递送胰岛素方面做出的努力。在糖尿病患者中,与经口施用胰岛素以达到正常血糖相关的问题在药品以及医学文献中有很好的引证。胃肠道中的消化酶迅速降解胰岛素,从而导致产生生物学分解的产物。例如在胃内,经口施用的胰岛素经历酶促蛋白酶解以及酸性降解。过度的蛋白酶解阻碍在肠中的存活。在腔(lumen)中,多种酶包括胃以及胰酶、外-和内-肽酶以及刷状缘肽酶阻塞胰岛素。既使胰岛素经受得住这些酶的攻击,但体内,在胰岛素到达其受体之前必须穿过的生物屏障可能限制胰岛素的经口施用。例如,胰岛素可能拥有低膜透性,从而限制了其经过腔进入血流的能力。
像胰岛素这种药学活性多肽已被与聚乙二醇的多分散混合物或含有聚乙二醇的聚合物的多分散混合物缀合,以提供药物-低聚物缀合物的多分散混合物;US4,179,337(Davis等)报道了缀合多肽,例如胰岛素与各种聚乙二醇,如由UnionCarbide提供的MPEG-1900和MPEG-5000。US5,567,422(Greenwald)报道了生物学活性亲核体与聚乙二醇如m-PEG-OH(UnionCarbide)的缀合,其具有5,000道尔顿的数均分子量。
US5,359,030(Ekwuribe等)报道了多肽例如胰岛素与聚乙二醇修饰的糖脂聚合物和聚乙二醇修饰的脂肪酸聚合物的缀合。

发明概述
本发明涉及生产胰岛素-低聚物缀合物IN-105的方法,包括表达式为G-A-V-R-[B-链]-R-D-A-D-D-R-[A-链]的IN-105前体IP-F,用活化的低聚物处理IP-F,该低聚物在IP-F的LysB29位置和前导肽GAVR的N-末端氨基酸Gly1缀合。将IP-F与具有通式-CO-(CH2)n-(OCH2CH2)n-OCH3的低聚物缀合,其中n是1到8的整数,且两个n不同或相同;在优选实施方案中活化的低聚物的具有分子式C14H23NO8(CAS.no.622405-78-1),以获得式为胰岛素-CO-CH2-CH2-(OCH2CH2)3-OCH3的IN-105。
本发明涉及式为G-A-V-R-[B-链]-R-D-A-D-D-R-[A-链]的生物合成前体序列IP-F的用途。用于本发明的前导序列G-A-V-R不具有任何如文献披露的需要用来增强胰岛素在酵母中的表达的带负电荷的氨基酸。本发明的方法在胰岛素缀合物的制备中更加简单,并且更为经济,其中巧妙避开了几个用于获得生物学活性形式的纯胰岛素的纯化步骤。本发明产生的产物在IN-105前体IP-F的A链或C-肽(RDADDR)上没有缀合,且其中缀合发生在B链(LysB29),以及在前导链G-A-V-R的Gly上,然后对所述产物进行蛋白酶处理,以获得胰岛素-低聚物缀合物IN-105。该方法使得生产缀合的胰岛素的总成本降到最低。
发明详述
IP-X代表式为Z-[B-链]-Q-[A-链]的胰岛素-低聚物前体,其中Z是前导肽序列,B-链是人胰岛素的B链或其类似物,Q是A和B链之间的接头肽序列,A-链是人胰岛素的A链或其类似物。前导肽包括,例如肽,GAVR,ARR,AARAARGR,HHHHHHAAR以及HHAHAHAHAAR。接头肽Q包括,例如RDADDR、RDALQR、REEAEAEAEPR、RPGR、RAR、RR以及R。
IP-X前体可以通过任何适当的表达系统制备,例如大肠杆菌(Escherichiacoli)、巴斯德毕赤氏酵母(Pichiapastoris)、啤酒糖酵母(Saccharomycescerevisiae)、CHO细胞等等。
在本发明IP-X最优选的实施方案是其中的前导序列Z是GAVR,B-链是人胰岛素的B(1-30),接头肽Q是RDADDR,而A-链是人胰岛素的A(1-21)。由式G-A-V-R-[B-链]-R-D-A-D-D-R-[A-链]代表的IP-X前体在下文中被称为IP-F。IP-F与Mat-α信号肽在巴斯德毕赤氏酵母表达载体,pPIC9K中符合读框地进行克隆。用该重组质粒转化巴斯德毕赤氏酵母宿主菌株,GS115,以获得表达IPF的毕赤氏酵母克隆。用胰蛋白酶、羧肽酶B(carboxpeptidaseB)和N-氢化琥珀酰胺酯(hydrosuccinamideester)(活化的低聚物)处理分泌的IP-F,以产生IN-105。
IN-105前体IP-F的序列。
序列:为在巴斯德毕赤氏酵母中表达最优化的密码子
预计分子量:6907.82Da
估计的pI值:5.46
核苷酸(183bp)和氨基酸(61aa)
IN-105前体IP-F被巴斯德毕赤氏酵母分泌到培养基内。离心液体培养基,且将细胞与上清液分离。有多种选择可以有效捕获前体IP-F,包括疏水作用层析和离子交换层析。在本发明中使用阳离子交换层析和HIC捕获IP-F。
IN-105前体IP-F的结晶去除了从发酵液到SP-琼脂糖凝胶洗脱汇集物(pool)过程中携带的所有杂质,这有助于在RP-HPLC-1阶段减少柱污损。用来从离子交换柱上洗脱产物的乙酸铵盐也通过结晶被去除。纯结晶前体还有助于降低在随后的缀合步骤中的成本和提高反应效率。结晶形式可被冷冻并贮藏,当贮藏在-20℃时基本上可在多天内保持稳定。
通过如下反应生产IN-105,其中IP-F首先在B29赖氨酸上用活化低聚物缀合,以产生IP-F-低聚物缀合物。用蛋白酶处理该IP-F-低聚物缀合物,其中接头-肽(RDADDR)和前导序列(GAVR)被切割,以得到活性胰岛素-低聚物缀合物。所用的两种蛋白酶是胰蛋白酶和羧肽酶B。由于LysB29被低聚物封闭,所以在LysB29的胰蛋白酶切割的几率最低。但其它的可能被胰蛋白酶切割的位点是B-22(Arg)、C-1(Arg)和C-6(Arg)的c-末端。进行第二次蛋白酶(羧肽酶B)处理以从B链除去游离的碱性(Arg)氨基酸,其中在B-30(Thr)附着一个额外的Arg,以获得最终产品IN-105。在最优反应条件下两种蛋白酶的处理是在一个操作中进行的,其中得率最大化,而形成的相关杂质则最少化。
酶切割反应完成后,可以将杂质从IN-105中分离,例如第一个RP-HPLC步骤。本发明中,当第一个RP是在低pH下进行,而最终纯化在高pH下进行时,去除了杂质。以15g/L树脂的装载实行低装载和20到35的梯度。第一个RP-HPLC步骤获得的纯度为~93-95%。有许多杂质需要被去除,其中第一个RP-HPLC步骤后剩余的杂质通过使洗脱汇集物进行另一轮RP-HPLC被纯化。IN-105最终产品的纯度为97-98%。
尽管RP-HPLC是用于纯化密切相关杂质的最优选步骤,但也可以采用利用不同纯化技术,如离子交换、HIC(疏水作用层析)等等的低压层析。
