Description

作为Toll样受体激动剂的嘧啶并哒嗪酮类化合物 技术领域
本发明属于化学医药领域,特别是涉及作为TLR7/8激动剂的嘧啶并哒嗪酮化合物,及其制备方法及其应用。
背景技术
Toll样受体(toll-like receptors,TLRs)是一类结构保守的蛋白质,在先天免疫反应中形成第一道屏障。通过识别各种保守的病原体相关分子模式(pathogen-associated molecular patterns,PAMPs),TLRs可以识别侵入性微生物和组织损伤或非生理性细胞死亡后释放的内源性分子,并激活信号级联反应,从而导致促炎性细胞因子的产生。炎症过程对多种疾病的发生和发展至关重要,例如I型糖尿病,败血症,癌症,病毒感染性疾病等。因此,通过小分子TLRs调节剂操纵炎症反应治疗相关疾病的策略是很有前景的。
人TLRs家族有10个已知成员,它们是I型跨膜蛋白,其特征是具有富含亮氨酸的胞外结构域和包含保守的Toll/白介素-1受体(Toll/interleukin(IL)-1 receptor,TIR)结构域的胞质尾巴。在该家族中,TLR3,TLR7,TLR8和TLR9位于内涵体隔室。
TLR7和TLR8均可识别来自单链RNA病毒的RNA分子(ssRNA)。TLR7主要在浆细胞样树突状细胞和B细胞内表达。TLR8主要分布在mDC,巨噬细胞和单核细胞中,在T细胞也有表达。TLR7刺激主要诱导I型干扰素的产生,包括干扰素-α(IFN-α),并引起干扰素刺激基因(ISGs)的转录。干扰素α是治疗慢性乙型或丙型肝炎的主要药物之一。TLR8主要分布在mDC,巨噬细胞和单核细胞中,在T细胞也有表达。TLR8激活主要产生促炎症应答,刺激免疫细胞分泌包括肿瘤坏死因子-(TNF-)、IL-6等促炎症细胞因子。TLR7/8的分布和下游信号通路存在重叠,因此功能上有相似性。TLR7/8激活后,可以通过I型干扰素应答发挥直接的抗病毒活性,也可以通过促炎症应答调节固有免疫促进NK和NKT细胞的激活,以及诱导适应性免疫,改善抗原呈递和激活树突状细胞,从而增强T细胞反应,可促进产生抗体的B细胞分化。开发TLR7/8激动剂在抗病毒治疗和抗肿瘤治疗中均有重大的临床价值,也可用于抗体偶联药物和疫苗佐剂中。
当前有几种相关的TLR7/8激动剂专利申请,但仍然需要继续开发高活性、更安全和治疗高度有效的TLR7/8激动剂。

药代动力学实验委托美迪西普亚医药科技(上海)有限公司完成,受试动物为ICR小鼠(上海西普尔-必凯实验动物有限公司)。通过静脉(iv)注射向ICR小鼠给测试化合物。iv的剂量是2mg/kg,溶媒系统为100%Saline(0.9%saline)。动物给药前禁食过夜(10-14小时),给药4小时后给食。给药后在多个时间点(0.083,0.25,0.5,1,2,4小时)收集血液于肝素钠抗凝管中。
灌胃(po)向ICR小鼠给测试化合物。po的剂量是5mg/kg,溶媒系统为100%Saline(0.9%saline)。动物给药前禁食过夜(10-14小时),给药4小时后给食。给药后在多个时间点(0.5,1,3,5小时)收集血液于肝素钠抗凝管中。
皮下给药(sc)向ICR小鼠给测试化合物。sc的剂量是5mg/kg,溶媒系统为100%Saline(0.9%saline)。动物给药前禁食过夜(10-14小时),给药4小时后给食。给药后在多个时间点(0.5,1,3,5小时)收集血液于肝素钠抗凝管中。处理样品,以LC-MS/MS方法分析药物在血浆中的浓度,用Phoenix WinNonlin计算药代参数。
结果显示,本发明化合物具有特殊的药代动力学性质,具备较好的成药性。
