Abstract
本发明提供一种如下式(I)所示的含N多环化合物的制备方法与用途,本发明的化合物具有更低的皮肤刺激性,适宜开发为皮肤外用制剂,同时本发明的化合物更能有效促进脱毛后毛发的生长,具有较大的临床价值。
Description
技术领域
本发明涉及但不限于医药技术领域,本发明提供药学活性的含N多环化合物及其组合物的制备方法,此类衍生物可用于治疗或预防JAK3介导的相关疾病。
背景技术
Janus Kinase(JAK)是一种非受体酪氨酸激酶,主要有三种亚型(JAK1、JAK2、JAK3),在细胞因子信号传导中起主要作用,在多种细胞分化过程中发挥重要作用。JAK的突变、过度表达或调节异常均会导致信号通路过度活化或信号通路失活均会引起多种炎症、皮肤病相关疾病、心血管疾病、代谢性疾病以及神经和神经变性疾病、免疫性疾病及肿瘤相关疾病的爆发。因此,JAK作为一种重要的酶已经成为一种研发药物用于治疗性干预的靶标。当细胞因子如IFN-a、IFN-β、IFN-γ、IL-10、IL-19等与受体结合后激活JAK,接着JAK磷酸化细胞因子受体成为信号传导的分子。目前,针对不同JAK开发的抑制剂对皮肤病具有较好的疗效,但是仍然需要开发选择性的JAK抑制剂,动物研究表明选择性抑制JAK3的活性对多种免疫病症具有明显的治疗作用,并且可以避免JAK2依赖性红细胞生成素(Erythropoietin,EPO)和血小板生成素(Thermoplastic polyolefin,TPO)信号传导。
2020年12月11日,辉瑞公司的JAK3抑制剂Ritlecitinib被CDE授予突破性疗法,用于对治疗≥12岁脱发患者的治疗。虽然相比于第一代JAK抑制剂其药物毒性有所降低,但是其药物安全性仍然有待于进一步评估。因此,目前仍然需要开发具有较好疗效、更低毒副作用的药物分子。

实施例十六:MTT法测定含N多环化合物细胞毒性
在96孔板上以1×104密度种植人正常肝细胞(HHL-5细胞),每孔加入200μL PBS,细胞均匀贴壁后置于37℃培养箱中孵育24h,待细胞浓度在1×105以上,加入预先配置好的含N多环化合物或化合物1溶液50μL(含有0.2%DMSO的培养基),最终药物浓度控制为10μM,每组重复三孔,加药完毕后置于37℃培养箱中孵育24h。用PBS将MTT配成5.0mg/mL,每孔加入20μL,加入完毕后再置入培养箱中孵育4.0h,去除培养基,向每孔中加入200μLDMSO,震荡均匀后于490nm波长下测定每孔的吸光度,以未加药孔的吸光度值作为细胞存活100%,采用Graphpad Prism7.0软件计算细胞存活率,数据以百分比表示。数据如下表1:
表1:MTT法测定细胞存活率
实验结果显示,与对照品相比,合成的含N多环化合物处理的正常细胞具有更高的存活率,表明合成的含N多环化合物对正常细胞的毒性显著降低。
实施例十七:测定含N多环化合物皮肤刺激性
取健康,体重2.50±0.25kg的家兔24只,雌雄各半,随机分为六组(DSC5125组、DSC5126组、DSC5130组、DSC5138组、DSC5149组、化合物1组),每组4只,雌雄各半。分别去除大鼠脊柱两侧的毛,注意避免损伤皮肤,脊椎两侧去毛面积均为3.0cm×3.0cm。次日将对应的化合物配置成10.0mg/mL的溶液,涂抹对应的大鼠脱毛后一侧的皮肤上,涂抹体积为0.2mL,涂抹面积1.5cm×1.5cm,涂抹完成后用无刺激性膜覆盖并固定,另外一侧皮肤不涂药,作为对照。每天给药1次,连续给药14天(为了保证实验的准确性,必要时需重新剪毛)。分别于每天去除药物后(用40℃的纯净水清洗去除药物)1.0h及末次给药去除药物后1h、24h、48h和72h观察皮肤局部反应,并按下表2对刺激性进行评分:
表2:皮肤刺激反应评分标准
每只动物对化合物的原发刺激指数为皮肤分别在1h、24h、48h、72h红斑和水肿的总分除以观察的总数。平均原发刺激分值为试验动物的原发刺激指数和除以试验的动物总数。实验结果如表3:
表3:化合物对家兔的皮肤刺激反应结果
上述刺激性实验数据说明本发明合成的化合物具有更低的得分,相比于化合物1具有更低的皮肤刺激性。预期本发明的化合物DSC5125、DSC5126、DSC5130、DSC5138、DSC5149可开发为皮肤外用制剂。
实施例十八:化合物对大鼠脱毛区新生毛发长度的影响
取SD大鼠100只,然后随机分为5组,每组20只,分别为:正常对照组、模型对照组、米诺地尔组、DSC5126组、DSC5149组。正常对照组使用剪刀将大鼠背部剪成2.5cm×2.5cm的方形区域。模型对照组、米诺地尔组、DSC5126组、DSC5149组采用松香/蜡混合物在大鼠的背部制成2.5cm×2.5cm的方形区域。将化合物米诺地尔、DSC5126、DSC5149分别配制成0.1mM的溶液,分别均匀涂抹于相应组大鼠的脱毛区域,每次涂抹0.2mL,正常对照组和模型对照组仅涂抹0.2mL的清水,每次涂抹均匀15分钟后,用清水冲洗干净,每日操作此涂抹步骤一次,连续涂抹30天,观察脱毛区毛发生长状况,同时用游标卡尺测量毛发的长度,用组内大鼠新生毛发程度的加权平均值作为最终的毛发长度,数据处理如表4。
表4:化合物对大鼠脱毛区新生毛发长度的影响
组别 | 动物数(只) | 给药浓度(mM) | 给药剂量(mL) | 新生毛发长度(mm) |
正常对照组 | 20 | --- | 0.2 | 10.7±0.9 |
模型对照组 | 20 | --- | 0.2 | 3.1±1.1 |
米诺地尔组 | 20 | 0.1 | 0.2 | 4.8±0.7 |
DSC5126组 | 20 | 0.1 | 0.2 | 7.0±1.0 |
DSC5149组 | 20 | 0.1 | 0.2 | 7.3±0.8 |
数据表明,模型组大鼠的毛发生长速度明显变小,说明造模成功。给药组大鼠的毛发生长速度明显高于模型对照组大鼠的毛发生长速度,与米诺地尔组大鼠的毛发生长速度相比,DSC5126组、DSC5149组大鼠的毛发生长速度明显高于米诺地尔组大鼠的毛发生长速度,取得了意想不到有益技术效果。
本申请描述了多个实施例,但是该描述是示例性的,而不是限制性的,并且对于本领域的普通技术人员来说显而易见的是,在本申请所描述的实施例包含的范围内可以有更多的实施例和实现方案。
