Definitions

  • the disclosure relates to a new camptothecin compound, or its stereoisomer or pharmaceutically acceptable salt, a pharmaceutical composition containing them and its use as an antitumor drug.
  • Camptothecin is a quinoline alkaloid extracted from Camptotheca acuminata. Due to its significant cytotoxic activity, it is often used in research related to cancer therapy. Subsequent studies on related mechanisms have shown that camptothecin has the activity of inhibiting topoisomerase I, and it can combine with the complex of topoisomerase I and DNA to form a stable ternary complex, thus hindering the topoisomerase I-mediated The induced DNA breaks, thereby blocking the processes of DNA replication, transcription and repair, and finally leading to cell cycle arrest and cell apoptosis.
  • camptothecin has problems such as low solubility, poor chemical stability, and obvious toxic and side effects, which ultimately hinder its clinical application.
  • camptothecin derivatives such as topotecan and irinotecan obtained by transforming camptothecin were successfully used to treat malignant tumors such as ovarian cancer, lung cancer and colorectal cancer.
  • these clinical drugs still have the problems of low solubility and poor chemical stability leading to low oral bioavailability, as well as severe clinical adverse reactions such as vomiting and bone marrow suppression. Therefore, improving the physical and chemical properties, activity and safety of camptothecin drugs is still an urgent problem to be solved.

技术领域
本公开涉及一种新的喜树碱类化合物、或其立体异构体或药学上可接受的盐,含有它们的药物组合物及其作为抗肿瘤药物的用途。
背景技术
喜树碱(Camptothecin)是从中国蓝果树科植物喜树(Camptotheca acuminata)中提取获得的一种喹啉类生物碱。由于其具有显著的细胞毒活性,因此经常用于癌症治疗相关研究当中。后续相关机制研究表明,喜树碱具有抑制拓扑异构酶I的活性,其能够与拓扑异构酶I与DNA的复合物结合,形成稳定的三元复合物,从而阻碍拓扑异构酶I介导的DNA断裂,进而阻断DNA复制、转录和修复等过程,最终导致细胞周期阻滞,细胞凋亡。
早期临床显示,喜树碱存在溶解度低、化学稳定性差以及毒副作用明显等问题,最终阻碍其临床应用。后续通过对喜树碱进行改造得到的拓扑替康(topotecan)、伊立替康(irinotecan)等喜树碱类衍生物成功用于治疗卵巢癌、肺癌及结直肠癌等恶性肿瘤。尽管如此,这些临床药物仍存在溶解度低、化学稳定性差导致口服生物利用度低的问题,以及伴随有呕吐、骨髓抑制等严重临床不良反应的发生。因此,改善喜树碱类药物的理化性质、提高活性及安全性仍是目前亟待解决的问题。

当其中一个变量选自化学键或不存在时,表示其连接的两个基团直接相连,比如A-L-Z中L代表键时表示该结构实际上是A-Z。
当本文中涉及到的连接基团若没有指明其连接方向,则其连接方向是任意的。例如当结构单元

二、试验步骤
1.Caco-2细胞培养
1)转运缓冲液(含25mM HEPES的HBSS,pH 7.4)的配制:精确称量5.958g HEPES和0.35g NaHCO 3,加900mL纯水让其溶解,然后加100mL 10×HBSS搅拌均匀,调pH至7.4,过滤。

2)用电阻仪测量单层膜电阻,记录每孔电阻。
3)测量完毕后,将Transwell培养板重新孵育。
4)计算TEER值:
TEER值=TEER测量值(Ω)×膜面积(cm 2)
单层细胞膜的电阻<230Ω·cm 2,表明单层细胞膜致密性差,不能用于试验。
4.转运实验
1)用DMSO稀释10mM的本公开化合物或阳性对照化合物的储备液得到2mM的储备液,然后用转运缓冲液稀释2mM的储备液得到10μM的本公开化合物或阳性对照化合物的工作液。

I acceptor(I 接收端)指接收侧(0.3mL)的荧光密度,I donor(I 供体)指给药侧(0.1mL)的荧光密度。LY>1.0%表明单层细胞膜致密性差,相应的结果将从评估中排除。
测定化合物在给药侧和接收侧的峰面积,计算化合物的表观渗透系数(P app,单位:cm/s)和外排比(Efflux ratio):
P app={V A×[drug] acceptor/(Area×incubation time×[drug] initial donor}
V A为接收端溶液的体积(A→B是0.3mL,B→A是0.1mL),Area(膜面积)为Transwell-96孔板膜面积(0.143cm 2);incubation time为孵育时间(单位:s);[drug] acceptor([药物] 接收端)为接收端药物浓度;[drug] initial donor([药物] 初始,供体)为给药侧药物初始浓度。
