本发明公开一种新型的冬凌草甲素去6位羟基类似物及其衍生物、其制备方法及医药用途，新型的冬凌草甲素去6位羟基类似物及其14位羟基衍生物，结构如式I所示；本发明还公开了这些新型化合物的制备方法以及其在治疗肿瘤疾病领域的应用。
Description
技术领域
本发明涉及天然药物及药物化学领域，具体涉及一类新型的冬凌草甲素去6位羟基类似物及其14位羟基衍生物。本发明还公开了这些新型化合物的制备方法以及其在治疗肿瘤疾病领域的应用。
背景技术
三阴性乳腺癌(TNBC)是指雌激素受体(ER)、孕激素受体(PR)、人表皮生长因子受体-2(HER-2)表达均为阴性的一类乳腺癌，占所有乳腺癌患者的15％-20％，这类乳腺癌的恶性程度高、肿瘤侵袭性强、预后较差、内分泌治疗及靶向治疗不敏感(见Fresia PareJaandJorge S.Reis-Filho.Nature Reviews Clinical Oncology，2018，15，6)。因此，目前缺乏合适的三阴性乳腺癌治疗方法，治疗药物以传统的蒽环类药物、紫杉烷、铂类等药物为主，但其疗效一般且具有毒副作用大的缺陷(见Kwang Ai Won Charles Spruck.IntJOncol,2020,57,1245-1261)。
冬凌草甲素是唇形科(Labtea)香茶菜属(Rabdosia)植物冬凌草的主要活性成分，具有抗炎、抗菌和抗肿瘤等活性(见Liu Z,Ouyang L,Peng H,et al.Cell Proliferat,2012,45,499)。研究发现天然产物冬凌草甲素具有潜在的抗TNBC治疗效果，但其活性较为中等，阻碍了其进一步的临床应用(见Hong Yao,Shengtao Xu,Jinyi Xu.J.Med.Chem.2020,63,15)。冬凌草甲素中具有多个羟基基团，羟基过多影响透膜性质，导致体内抗肿瘤活性不够强。因此，有必要对其羟基进行结构改造研究，发现活性更优、安全性更高的新型化合物。
发明内容
本发明通过去除冬凌草甲素6位羟基并对14位羟基进行结构修饰，提供一类具有抗肿瘤活性的新化合物。与已有的同类化合物相比，本发明的化合物具有更优的细胞透膜性，更强抑制三阴乳腺癌生长的活性，并具有良好的选择性。
本发明是通过以下技术方案实现的。
通式Ⅰ所示的冬凌草甲素类似物及衍生物，及其光学活性体或消旋体、非对映异构体混合物，或其可药用盐：

【药理活性】
药理试验证明，本发明的新型冬凌草甲素类似物及衍生物具有抗三阴性乳腺癌作用，并具有良好的选择性，可以用于制备抗肿瘤药物，选用细胞株人乳腺癌细胞MDA-MB-468及正常乳腺细胞MCF-10A进行药理实验。
下面是本发明部分化合物的药理实验结果：
1、部分化合物对三阴乳腺癌细胞生长的影响
实验设备与试剂
仪器超净工作台(苏州艾可林净化设备有限公司)
恒温CO2培养箱(日本SANYO)
酶联免疫检测仪(美国BIO-RAD)
倒置生物显微镜(日本OLYMPUS)
试剂青、链霉素混合液(南京凯基生物科技发展有限公司)

DMSO(SIGMA)
细胞株人乳腺癌细胞MDA-MB-468
正常乳腺细胞MCF-10A
实验方法
1.细胞消化、计数、制成浓度为5×104个/mL的细胞悬液，96孔板中每孔加入100μL细胞悬液(每孔5×103个细胞)；
2.96孔板置于37℃，5％CO2培养箱中培养24小时；
3.用完全培养基稀释药物至所需浓度，每孔加入100μL相应的含药培养基，同时设立阴性对照组，溶媒对照组，阳性对照组；
4.96孔板置于37℃，5％CO2培养箱中培养72小时；
5.将96孔板进行MTT染色，λ＝490nm，测定OD值。
1)每孔加入20μL MTT(5mg/mL)，在培养箱继续培养4小时；
2)弃去培养基，每孔加入150μL DMSO溶解，摇床10分钟轻轻混匀；λ＝490nm，酶标仪读出每孔的OD值，计算抑制率。
细胞抑制率％＝100％×(阴性对照组OD值-化合物组OD值)/阴性对照组OD值
