Abstract
本发明涉及一类肠道裂解型共药(Codrug)及其制备和用途,具体地,本发明提供了一种如式I所示的共药化合物。本发明还提供了使用这类化合物治疗胃肠道自身免疫性疾病、炎症性疾病和癌症的方法;以及用于制备这类化合物的方法和中间物。
Description
技术领域
本发明涉及一类肠道裂解型共药化合物。本发明还涉及包括这类化合物的药物组合物;使用这类化合物治疗胃肠道自身免疫性疾病、炎症性疾病和癌症的方法;以及用于制备这类化合物的方法和中间物。
背景技术
JAK抑制剂如托法替尼已被批准用于治疗患有中度到重度活动性类风湿性关节炎(rheumatoid arthritis,RA)和中重度溃疡性结肠炎(ulcerative colitis,UC)的某些患者。在许多JAK抑制剂的临床试验中,报道了大量全身性药物暴露介导的不良事件,包含严重感染、机会性感染及实验室异常,例如淋巴细胞減少症、中性粒白细胞减少症、肝酶升高、脂质升高和血清肌酐升高。目前上市的JAK抑制剂均带有安全风险的黑框警告,包含严重感染、恶性肿瘤以及血栓风险。因此,开发新一代更安全的JAK抑制剂药物在治疗局部发炎疾病时将需要限制其全身性暴露量。例如治疗UC时,增加JAK抑制剂在胃肠道中的分布量,同时最小化药物的全身性暴露量。
小檗碱(Berberine)又名黄连素,是从黄连等植物中提取的一种异喹啉生物碱。小檗碱是一种非常安全的药物,在传统中药的应用中已有一千多年历史。其生物利用度很低。临床上主要用于治疗腹泻、肠道感染等胃肠道疾病。近年来的研究也发现小檗碱在心血管疾病、糖脂代谢调控方面也具有一定的治疗前景。小檗红碱(Berberrubine)是小檗碱在体内的主要代谢产物。动物模型研究发现,小檗红碱对溃疡性结肠炎具有与小檗碱类似的治疗效果。然而截止目前,本领域尚缺乏提高小檗碱或其类似物的治疗效果的有效途径。
慢性肠炎主要包括溃疡性结肠炎和克罗恩病两种类型。这些慢性肠道炎性疾病病程漫长,常反复发作,且长期的炎症易发生癌变。近年来慢性肠炎发病率呈上升趋势。目前认为慢性肠炎的发病可能与遗传、环境、免疫和微生物有关,但其确切机制并不清楚。临床上的治疗以氨基水杨酸类药物、肾上腺糖皮质激素类药物及免疫抑制剂为主,但都存在一定的不良反应,如胃肠道不适、过敏反应等。我们在此前的工作中发现,JAK抑制剂联合小檗碱类似物能协同作用达到更加优越的治疗胃肠道炎症性疾病的效果。本发明通过设计一类肠道裂解型小檗碱类似物和JAK抑制剂共药化合物,使得两个药物分子在胃肠道释放和富集,而化合物在全身系统性的暴露得到限制。两个药物分子协同作用达到更优的治疗效果和安全性。
发明内容

在本申请中,术语“治疗”和其它类似的同义词包括以下含义:
(i)预防疾病或病症在哺乳动物中出现,特别是当这类哺乳动物易患有该疾病或病症,但尚未被诊断为已患有该疾病或病症时;
(ii)抑制疾病或病症,即遏制其发展;
(iii)缓解疾病或病症,即,使该疾病或病症的状态消退;或者
(iv)减轻该疾病或病症所造成的症状。
在本申请中,术语“有效量”、“治疗有效量”或“药学有效量”是指服用后足以在某种程度上缓解所治疗的疾病或病症的一个或多个症状的至少一种药剂或化合物的量。其结果可以为迹象、症状或病因的消减和/或缓解,或生物系统的任何其它所需变化。例如,用于治疗的“有效量”是在临床上提供显著的病症缓解效果所需的包含本文公开化合物的组合物的量。可使用诸如剂量递增试验的技术测定适合于任意个体病例中的有效量。

与现有技术相比,本发明的主要优点在于:
1.本发明的共药化合物本身不能被有效吸收,它能够在肠道定向释放两个药效组分,因此可以造成药效成分在胃肠道治疗部位的富集,而减少全身性的药物暴露。
2.本发明化合物能够在肠道有效释放JAK抑制剂(例如托法替尼)和小檗红碱或其类似物协同治疗胃肠道自身免疫性炎症性疾病。

生物测试1:共药化合物(co-drug)在小鼠十二指肠或结肠内容物中离体释放实验(lumen content ex vivo assay).
C57BL/6雄性小鼠(6-8周龄),二氧化碳安乐死后解剖。取出十二指肠和结肠段置于1.5毫升离心管,同时加入PBS溶液。纵向切开肠段,晃动释放肠内容物,颠倒混匀。分别配置实施例化合物的二甲基亚砜溶液,各取20微升上述二甲基亚砜溶液置于1毫升十二指肠或结肠内容物的PBS溶液中。反复颠倒混匀,置于37度的水浴中。在1小时,4小时,16小时的节点分别取100微升上述溶液,加入100微升乙腈,溶液进行涡旋,离心10分钟。取100微升上层清液,加入内标化合物(中间体D)10微升。液相色谱质谱联用仪检测并标准曲线定量实施例化合物、小檗红碱和托法替尼的量(ng),结果如图1-图6中所示。结果显示,相较于托法替尼或小檗红碱单独给药的情况,本发明的共药化合物在给药后能够以显著更快的速度在肠道内进行释放。
生物测试2:共药化合物在小鼠体内药代动力学实验
口服(PO,15mg/kg)给予CD-1小鼠测试化合物,于不同时间点采集血样和胃肠道各段组织样品。LC-MS/MS测定小鼠血浆中实施例共药化合物以及其释放出来的托法替尼和小檗红碱的浓度。给药实验开始时动物年龄约6-8周。采血和组织样品时间:给药后0.5,1,2,4,8和24小时。建立生物样品分析方法及样品检测方法。
结果如图7-11中所示。结果表明,实施例共药化合物能在小鼠肠道内释放托法替尼和小檗红碱,且共药化合物、托法替尼和小檗红碱均主要限制在肠道组织,血浆中只有极低的药物暴露。
生物测试3:共药化合物在恶唑酮诱导的小鼠结肠炎模型上的药效实验
C57BL/6小鼠,参考Heller等方法建立恶唑酮诱导结肠炎模型。第1天将小鼠颈背部皮肤剃毛(2cm×2cm),并涂抹3%恶唑酮溶液(溶解于丙酮加橄榄油4:1混合溶液中)150ul以致敏。致敏后第6天将小鼠随机分组。随后开始灌胃给予相应实施例化合物(120mg/kg),空白对照组和模型组给予溶剂,灌胃体积10ml/kg体重。随后第二天1.2%恶唑酮溶液50ul灌肠,空白对照组注入纯水。后续灌胃给药持续4天,每天记录疾病活动指数(DiseaseActivity Index,DAI),结果如图12所示。实施例共药化合物给药组和模型组比较,能显著改善疾病活动指数。
