Description

一类3,4-二氢-2H-苯并[b][1,4]噁嗪类化合物及其制备方法
本申请主张如下优先权：
CN202110933020.4，2021年08月13日。
技术领域
本发明涉及一类3,4-二氢-2H-苯并[b][1,4]噁嗪类化合物及其制备方法，以及该类化合物在制备治疗相关疾病药物中的应用，具体涉及式(Ⅰ)所示化合物及其药学上可接受的盐。
背景技术
肿瘤免疫疗法是近年来备受关注的治疗领域，主要机理是通过调动机体的免疫系统，增强免疫微环境的抗肿瘤能力。目前已有肿瘤免疫治疗的单抗药物如Keytruda和OPDIVO等用于非小细胞肺癌和黑色素瘤等多种癌症的治疗。
维甲酸相关孤儿受体(RAR-related orphan receptor，RORs)属于核受体超家族，是细胞内转录因子的一员，能够调控多种生理过程，包括生殖发育、新陈代谢、免疫系统调节等。ROR有三个家族成员：ROR-α、-β和-γ，分别由RORA、RORB、RORC基因编码。RORγ又包括RORγ1和RORγt(RORγ2)两种亚型。RORγ1在胸腺、肌肉、胰腺、前列腺和肝脏等多种组织和器官中表达，而RORγ的短链亚型RORγt主要分布于胸腺，促进初始T细胞向Th17和Tc17细胞分化。Th17和Tc17细胞通过分泌IL-17，IL-22，GM-CSF等细胞因子和炎症因子，促进炎症反应和自身免疫应答。IL-17可以促进肿瘤微环境中CTLs和NK细胞的招募和浸润，提升效应T细胞的抗肿瘤作用。
RORγ激动剂目前没有药物获批上市，Lycera Corp公司的RORγ激动剂LYC-55716单药用于晚期实体瘤的治疗处于临床二期研究，与PD-1单抗pembrolizumab联用治疗晚期非小细胞肺癌的治疗处于临床1b期研究。面对巨大的未满足市场，该领域仍然需要活性更好，药代动力学参数更优的候选化合物推进临床试验，以满足治疗需求。

除非另有说明，术语“互变异构体”或“互变异构体形式”是指在室温下，不同官能团异构体处于动态平衡，并能很快的相互转化。若互变异构体是可能的(如在溶液中)，则可以达到互变异构体的化学平衡。例如，质子互变异构体(proton tautomer)(也称质子转移互变异构体(prototropic tautomer))包括通过质子迁移来进行的互相转化，如酮-烯醇异构化和亚胺-烯胺异构化。价键异构体(valence tautomer)包括一些成键电子的重组来进行的相互转化。其中酮-烯醇互变异构化的具体实例是戊烷-2,4-二酮与4-羟基戊-3-烯-2-酮两个互变异构体之间的互变。
除非另有说明，术语“富含一种异构体”、“异构体富集”、“富含一种对映体”或者“对映体富集”指其中一种异构体或对映体的含量小于100％，并且，该异构体或对映体的含量大于等于60％，或者大于等于70％，或者大于等于80％，或者大于等于90％，或者大于等于95％，或者大于等于96％，或者大于等于97％，或者大于等于98％，或者大于等于99％，或者大于等于99.5％，或者大于等于99.6％，或者大于等于99.7％，或者大于等于99.8％，或者大于等于99.9％。

可以通过的手性合成或手性试剂或者其他常规技术制备光学活性的(R)-和(S)-异构体以及D和L异构体。如果想得到本发明某化合物的一种对映体，可以通过不对称合成或者具有手性助剂的衍生作用来制备，其中将所得非对映体混合物分离，并且辅助基团裂开以提供纯的所需对映异构体。或者，当分子中含有碱性官能团(如氨基)或酸性官能团(如羧基)时，与适当的光学活性的酸或碱形成非对映异构体的盐，然后通过本领域所公知的常规方法进行非对映异构体拆分，然后回收得到纯的对映体。此外，对映异构体和非对映异构体的分离通常是通过使用色谱法完成的，所述色谱法采用手性固定相，并任选地与化学衍生法相结合(例如由胺生成氨基甲酸盐)。

术语“任选被取代的”是指可以被取代，也可以不被取代，除非另有规定，取代基的种类和数目在化学上可以实现的基础上可以是任意的。
当任何变量(例如R)在化合物的组成或结构中出现一次以上时，其在每一种情况下的定义都是独立的。因此，例如，如果一个基团被0-2个R所取代，则所述基团可以任选地至多被两个R所取代，并且每种情况下的R都有独立的选项。此外，取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。

当一个取代基为空缺时，表示该取代基是不存在的，比如A-X中X为空缺时表示该结构实际上是A。当所列举的取代基中没有指明其通过哪一个原子连接到被取代的基团上时，这种取代基可以通过其任何原 子相键合，例如，吡啶基作为取代基可以通过吡啶环上任意一个碳原子连接到被取代的基团上。
当所列举的连接基团没有指明其连接方向，其连接方向是任意的，例如，

所述连接基团、取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。
除非另有规定，当某一基团具有一个或多个可连接位点时，该基团的任意一个或多个位点可以通过化学键与其他基团相连。当该化学键的连接方式是不定位的，且可连接位点存在H原子时，则连接化学键时，该位点的H原子的个数会随所连接化学键的个数而对应减少变成相应价数的基团。所述位点与其他基团连接的化学键可以用直形实线键

3.1实验目的：测试化合物在Balb/c小鼠体内的药代动力学
3.2实验材料：
Balb/c小鼠(雌性,7～9周龄,上海斯莱克)
3.3实验操作：
以标准方案测试化合物静脉注射(IV)及口服给药(PO)后的啮齿类动物药代特征,实验中给予小鼠单次静脉注射及口服给药。静注溶媒为5％二甲基亚砜、30％的PEG400、65％的羟丙基β环糊精(10％)配成的混合溶媒。口服溶媒为0.5％羟丙甲纤维素和0.2％吐温配成的混合溶媒。该项目使用四只雌性Balb/c小鼠,两只小鼠进行静脉注射给药,给药剂量为0.5mg/kg,收集0h(给药前)和给药后0.0833,0.25,0.5,1,2,4,8,24h的血浆样品,另外两只小鼠口服灌胃给药,给药剂量为1mg/kg,收集0h(给药前)和给药后0.25,0.5,1,2,4,8,24h的血浆样品,收集24小时内的全血样品,3000g离心15分钟,分离上清得血浆样品,加入4倍体积含内标的乙腈溶液沉淀蛋白,离心取上清液加入等倍体积的水再离心取上清进样,以LC-MS/MS分析方法定量分析血药浓度,并计算药代参数,如达峰浓度(C max),清除率(CL),半衰期(T 1/2),组织分布(Vdss),药时曲线下面积(AUC 0-last),生物利用度(F)等。
3.4实验结果如表4所示。
表4本发明化合物的药代动力学测试结果
Figure PCTCN2022111904-appb-000069
结论：本发明化合物具有良好的药代动力学性质,包括良好的口服生物利用度,口服暴露量,半衰期和清除率等。
实验例4：本发明化合物对MC38小鼠结肠癌移植瘤模型的体内药效学研究
4.1实验目的：
本实验的目的是研究本发明化合物对MC38小鼠结肠癌移植瘤模型体内药效进行评估。
4.2实验动物：
种属：小鼠
品系：C57BL/6小鼠
周龄及体重：7周龄,体重18-23克
性别：雌性
供应商：上海斯莱克实验动物有限公司
4.3实验方法与步骤
4.3.1细胞培养
名称：MC38(小鼠结肠癌细胞)
来源：和元生物技术(上海)有限公司。由辉源生物科技(上海)有限公司保种维持传代。
细胞培养：培养液为含有10％胎牛血清的1640培养基,培养条件为37℃,5％二氧化碳。传代比例为1:2～1:3,每周传代2～3次。
4.3.2肿瘤细胞接种
将0.1mL(2×10 5个)细胞皮下接种于每只小鼠的右后背。同日将动物根据体重随机分组。
4.3.3受试物的配制
实验用溶媒为5％DMSO/95％(20％羟丙基β环糊精)。受试物用溶媒溶解,配制成一定浓度均一溶液,于4℃保存。
4.3.4肿瘤测量和实验指标
实验指标是考察肿瘤生长是否被抑制、延缓或治愈。每周两次用游标卡尺测量肿瘤直径。肿瘤体积的计算公式为：V＝0.5a×b 2,a和b分别表示肿瘤的长径和短径。
化合物的抑瘤疗效用相对肿瘤增殖率T/C(％)评价。相对肿瘤增殖率T/C(％)：计算公式如下：T/C％＝T RTV/C RTV×100％(T RTV：治疗组RTV；C RTV：阴性对照组RTV)。根据肿瘤测量的结果计算出相对肿瘤体积(relative tumor volume,RTV),计算公式为RTV＝V t/V 0,其中V 0是分组给药时(即d 0)测量所得平均肿瘤体积,V t为某一次测量时的平均肿瘤体积,T RTV与C RTV取同一天数据。
4.4实验结果见表5。
