Abstract
本发明提供式II/III含氟化合物及抗癌医药用途。
Description
技术领域
本发明涉及对专利申请PCT/US2016/021581,公开号WO2016145092A1,对应中国申请号2016800150788,公开号CN107530556A所公开的化合物的进一步研发,得到一系列AKR1C3酶活化的DNA烷化剂,属于癌症治疗化合物研发领域。
背景技术
本申请引用
申请人于2019年05月13日申请的中国发明专利申请CN201910392606.7,主题名称含氟化合物及抗癌医药用途;
以及
申请人于2019年12月20日申请的中国发明专利申请CN201911324466.6,主题名称含氟化合物及抗癌医药用途。
我公司开发的以过表达醛酮还原酶1C3(AKR1C3)为标靶的DNA烷化癌症治疗药物(DNA烷化剂,对应PCT申请号PCT/US2016/021581,公开号WO2016/145092,对应中国申请号2016800150788,公开号CN107530556A)中的化合物均为黄色油状物。由于这些化合物不是固体,使得在后续的制剂研发上存在以下的困难:
分离纯化复杂,成本高。由于为油状物,无法使用效率高/成本低的重结晶或是打浆纯化(slurry),而只能使用柱层析方法进行纯化,导致操作复杂,原料药制备的成本高。
制剂不方便,稳定性差。由于为油状物,在转运/计量过程中都不便于操作,重要的是,对于油状物无法或不方便进行制剂剂型的开发和多样化选择,一般只能开发为冻干粉针或注射剂的方式进行给药,给药方式单一而且成本较高;另外冻干粉针或注射剂的方式进行给药对于某些患者而言,依从性不高。
发明内容
为了解决上述技术问题,本发明基于专利申请PCT申请号PCT/US2016/021581,公开号WO2016/145092,对应中国申请号2016800150788,公开号CN107530556A,名称为DNA烷化剂中公开的化合物进行了结构改造,并设计合成了一系列的含氟化合物。
为此,本发明将上述专利申请PCT申请号PCT/US2016/021581,公开号WO2016/145092,对应中国申请号2016800150788,公开号CN107530556A公开的内容引入本文。本文中对于定义概念有与上述申请不同或差别的,以本文为准;本文中出现的概念或是定义未有明确定义或是限制的,均遵照上述申请进行定义;其余本文及上述申请未定义的以有机化学、药物化学的教科书、手册等为准。
已经证明,专利申请PCT/US2016/021581、PCT/US2016/025665和PCT/US2016/062114中公开的化合物3424作为国际首创的、高度肿瘤选择性的小分子靶向治疗药物,在多种临床前细胞和动物模型中已表现出非常出色的抗癌效果。这些化合物作为醛酮还原酶AKR1C3特异性底物,可仅在AKR1C3高表达的癌细胞内快速有效地还原,从而释放细胞毒素导致高选择性的癌细胞杀伤药效。已经有文献(文献1:Richard B.Lock,Kathryn Evans,Raymond Yung,Tara Pritchard,Beverly A.Teicher,JianXin Duan,Yuelong Guo,Stephen W.Erickson,Malcolm A.Smith.The AKR1C3-Activated Prodrug OBI-3424Exerts Profound In Vivo Efficacy Against Preclinical Models of T-CellAcute Lymphoblastic Leukemia(T-ALL);a Pediatric Preclinical Testing ConsortiuLCM Study[abstract].In:Proceedings of the AACR-NCI-EORTC InternationalConference:Molecular Targetsand Cancer Therapeutics;2017Oct 26-30;Philadelphia,PA.Philadelphia(PA):AACR;Mol Cancer Ther 2018;17(1Suppl):Abstractnr LB-B16;文献2:Evans K,Duan J,Pritchard T,Jones CD,McDermottL,Gu Z,Toscan CE,El-ZeinN,MayohC,Erickson SW,Guo Y,Meng F,Jung D,Rathi KS,RobertsKG,Mullighan CG,Shia CS,Pearce T,Teicher BA,Smith MA,Lock RB.OBI-3424,a novelAKR1C3-activated prodrug,exhibits potent efficacy against preclinical modelsof T-ALL.Clin Cancer Res.2019Apr 23.pii:clin canres.0551.2019.doi:10.1158/1078-0432.CCR-19-0551)等文献证明AST-3424(OBI-3424)化合物(即2870号化合物的S构型异构体)在I期临床中显现出对白血病和肺癌等癌症具有较好的效果。
由于该系列化合物均为油状物,存在种种不足:储存、转运或计量均不便于操作,为此需要开发出常温下为固体的类似化合物。
研发团队曾想到使用这样的解决方法:通过成盐的方法来将油状物转化为固体的盐。但经过实验发现,使用无机酸如硫酸/盐酸等与含氮三元环进行成盐反应,得不到预期的盐:试验证实,上述的CN107530556A公开化合物在酸性条件下,其中的含氮三元环会开环得到开环副产物。经过多次实验尝试表明以上的常规方法不可行。
发明团队根据经验和实验结果,创造性地在上述化合物结构中的特别位置(比如硝基苯环和磷酸胺基团间)引入特别的三氟甲基、氟取代的芳基或杂芳基等含氟基团,经过此番改造后,发现所得的化合物均为固体(包括固体以及蜡状物)。
而且进一步体外实验证明,这些化合物具有较强的癌细胞体外增殖抑制活性,而且将化合物与AKR1C3抑制剂TH3021合用发现抑制活性减弱,由此证实特定位置引入特定含氟基团后,不仅能使得化合物为固体便于制剂、便于计量、便于储存,而且依然能得到AKR1C3酶活化的DNA烷化剂。
