Description
本申请是申请日为2016年5月26日、申请号为201680030136.4、发明名称为“具抑制细菌葡萄糖醛酸酶活性的吡唑并[4,3-c]喹啉衍生物”的发明专利申请的分案申请。
技术领域
本发明是关于抑制β-葡萄糖醛酸酶的新化合物,特别地,本发明提供吡唑并[4,3-c]喹啉(pyrazolo[4,3-c]quinoline)衍生物以抑制微生物β-葡萄糖醛酸酶。
背景技术
单离喜树碱(Camptothecin),从喜树(Camptotheca acuminata)分离的生物碱(Wall,M.E.;Wani,M.C.;Cook,C.E.;Palmer,K.H.;McPhail,A.T.;Sim,G.A.J.Am.Chem.Soc.1966,88,3888-3890;Werbovetz,K.A.;Bhattacharjee,A.K.;Brendle,J.J.;Scovill,J.P.Bioorg.Med.Chem.2000,8,1741-1747)已发现具有显著的抗癌活性(Wall,M.E.Camptothecin and taxol:discovery to clinic.Med.Res.Rev.18,299-314(1998))。然而,喜树碱的毒性颇剧烈且生物利用率低(J.F.Pizzolato,L.B.Saltz,Lancet 361,2235(2003)),导致临床利用受限制。运用半合方式将喜树碱制成的癌康定(Topotecan)和抗癌妥(irinotecan,CPT-11),目前在临床上以癌康定用于治疗卵巢癌和非小细胞肺癌,抗癌妥用于大肠癌的治疗(Mathijssen,R.H.,Loos,W.J.,Verweij,J.&Sparreboom,A.Pharmacology of topoisomerase I inhibitors irinotecan(CPT-11)andtopotecan.Curr.Cancer Drug Targets 2,103-123(2002))。CPT-11是一个前驱药(prodrug),具有胺甲酸酯(carbamate)连结的双呱啶基(dipiperidino)基团,此基团于生物体内(in vivo)形成具活性的SN-38代谢物。SN-38在肝脏内经由二磷酸尿苷(uridinediphosphate)葡萄糖醛酸转移酶(glucuronosyltransferase)形成无活性的SN38-葡萄糖 醛酸苷(SN38-glucuronide,SN-38G)后,从胆道排入肠胃道。一旦在肠道内,SN-38G作为微生物β-葡萄糖醛酸酶(microbiotaβ-glucuronidase,eβG)的底物(substrate),于水解成具生物活性的SN-38后,担任着腹泻的主要角色(Takasuna,K.et al.Optimal antidiarrheatreatment for antitumor agent irinotecan(CPT-11)-induced delayeddiarrhea.Cancer Chemother.Pharmacol.58,494-503(2006);Yong,W.P.,et al.Effectsof ketoconazole on glucuronidation by UDP-glucuronosyltransferaseenzymes.Clin.Cancer Res.11,6699-6704(2005))。
已发现eβG抑制剂可降低SN-38G的生物活性和减轻CPT-11导致的腹泻(Benson,A.B.,3rd et al.Recommended guidelines for the treatment of cancer treatment-induced diarrhea.J.Clin.Oncol.22,2918-2926(2004))。CPT-11在肝脏代谢成为SN-38G,随即分泌到胃肠(GI)道,并经eβG水解成为生物活性的SN-38G,然后导致肠道损伤和腹泻,以及CPT-11、SN-38及SN-38G的结构公开于Takasuna,K.et al.Optimal antidiarrheatreatment for antitumor agent irinotecan hydrochloride(CPT-11)-induceddelayed diarrhea.Cancer Chemother.Pharmacol.58,494-503(2006)。
葡萄糖醛酸化反应是人类药物排毒的主要途径。然而,在肠道菌群中经由β-葡萄糖醛酸酶(βG)降解的葡萄糖醛酸苷,在癌症化疗过程中引起严重的毒性反应,并发生促使大肠癌发展的癌变。目前使用的抗癌药物,如抗癌妥(CPT-11)(Kobayashi,K.Chemotherapy-induced diarrhea.Cancer&chemotherapy 30,765-771(2003))、5-氟尿嘧啶(5-FU)(Cascinu,S.et al.High-dose loperamide in the treatment of 5-fluorouracil-induced diarrhea in colorectal cancer patients.Supportive carein cancer,8,65-67(2000))、草酸铂(oxaliplatin)(Dranitsaris,G.,et al.Severechemotherapy-induced diarrhea in patients with colorectal cancer:a cost ofillness analysis.Supportive care in cancer,13,318-324(2005))会引发严重的化疗药物导致腹泻(chemotherapy-induced diarrhea,CID)副作用,因而可能导致的降低给药剂量或甚至化疗的中断(Viele,C.S.Overview of chemotherapy-induceddiarrhea.Semin.Oncol.Nurs.19,2-5(2003))。CID是一种常见的病症,尤其中晚期癌症病患更容易发生。因此,发现肠道内的特定βG抑制剂,即仅抑制如细菌的βG(E.coliβG;eβG),而非人类βG(hβG)的化合物颇具迫切需要性。
已发现一些βG抑制剂可降低SN-38G的生物活性,减轻CPT-11导致的腹泻(Benson,A.B.,3rd et al.Recommended guidelines for the treatment of cancer treatment-induced diarrhea.J.Clin.Oncol.22,2918-2926(2004))。例如,发现葡萄糖-1,4-内酯(glucaro-1,4-lactone)可改善因投予CPT-11导致的CID症状(Takasuna,K.et al.Optimalantidiarrhea treatment for antitumor agent irinotecan hydrochloride(CPT-11)-induced delayed diarrhea.Cancer Chemother.Pharmacol.58,494-503(2006))。然而,投予葡萄糖-1,4-内酯(一种非选择性的βG抑制剂),可能导致粘多糖症状副作用,因对hβG拥有强烈的抑制效应
(Fittkau,M.,et al.Saccharic acid 1,4-lactone protects against CPT-11-induced mucosa damage in rats.J.Cancer Res.Clin.130,388-394(2004);Constantopoulos,G.,et al.Experimental animal model for mucopolysaccharidosis:suramin-induced glycosaminoglycan and sphingolipid accumulation in therat.Proc.Natl.Acad.Sci.USA.77,3700-3704(1980))。另外,文献中揭示肠的eβG在葡萄糖醛酸苷共轭致癌剂的代谢活化过程中扮演重要的作用,从而导致结肠癌的形成(Kaderlik,K.R.et al.Metabolic activation pathway for the formation of DNA adducts ofthe carcinogen2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine(PhIP)in ratextrahepatic tissues.Carcinogenesis 15,1703-1709(1994);Nalini,N.,et al.Effectof coconut cake on the bacterial enzyme activity in 1,2-dimethyl hydrazineinduced colon cancer.Clin.Chim.Acta.342,203-210(2004);Nalini,N.,etal.Influence of spices on the bacterial(enzyme)activity in experimental coloncancer.J.Ethnopharmacol.62,15-24(1998))。Kim等公开抑制肠的eβG可降低结肠癌的发生,且在结肠癌患者中eβG的活性较正常对照组高达为12.1倍(Kim,D.H.&Jin,Y.H.Intestinal bacterial beta-glucuronidase activity of patients with coloncancer.Arch.Pharm.Res.24,564-567(2001))。Humblot,C.等证明肠的eβG和结肠的遗传毒性存在着正相关性(Humblot,C.et al.Beta-glucuronidase in human intestinalmicrobiota is necessary for the colonic genotoxicity of the food-bornecarcinogen 2-amino-3-methylimidazo[4,5-f]quinoline in rats.Carcinogenesis 28,2419-2425(2007))。最近,1-((6,8-二甲基-2-氧代-1,2-二氢基喹啉-3-基)甲基)-3-(4-乙氧苯基)-1-(2-羟乙基)硫脲(1-((6,8-Dimethyl-2-oxo-1,2-dihydroquinolin-3-yl)methyl)-3-(4-ethoxyphenyl)-1-(2-hydroxy-ethyl)thiourea)(βG-Inh,为为一公开的eβG专一抑制剂)为最有效且专一的eβG抑制剂(Wallace,B.D.et al.Alleviating cancerdrug toxicity by inhibiting a bacterial enzyme.Science 330,831-835(2010))。下列结构式为葡萄糖-1,4-内酯及βG-Inh的结构。
葡萄糖-1,4-內酯
美国专利第5447719号提供一β-葡萄糖醛酸酶抑制剂,至少包括选自黄芩苷(baicalin)、千层纸苷(oroxylin A-7-O-glucuronide)、木犀草素-3'-葡萄糖醛酸苷(luteolin-3'-glucuronide)的至少一化合物;黄芩根(scutellaria root)和荆芥穗(schizonepeta spike)萃取物;或含有作为生药的黄芩根及/或荆芥穗的中国或日本传统中药处方。美国公开专利第20130345235号涉及抑制细菌葡萄糖醛酸酶的苯氧基噻吩磺胺(phenoxythiophene sulfonamides),和包括一个或多个此类化合物的组合物及运用一个或多个此类化合物作为与一喜树碱衍生抗癌药物的并用药物(co-drug)使用的方法。
然而,βG-Inh的疗效和特异性并不理想,因此,更有效力的和选择性的eβG抑制剂鉴定,成为关注焦点。
发明内容
本发明提供一种具有下列结构式I的化合物,
本发明的化合物可作为(1)化疗佐剂(chemotherapy-adjuvant)以预防化疗导致的腹泻(CID)并增加癌症的化疗效果;(2)预防致癌物质诱发的大肠癌的健康食品补充剂。因此,本发明的化合物以及组合物用作为在生物体内治疗或预防化疗导致的腹泻和诱发结肠癌之致癌物质的疗法。在又一实施例中,本发明提供用于减少/抑制经由在生物体中的葡萄糖醛酸化反应代谢的治疗剂再活化的方法,包括对生物体投予有效量的化合物或如上述的组合物。

17(TCH-3511)、32(TCH-3510)对小鼠肠道中βG活性的抑制性以体内造影(In vivoimage)测定。5(TCH-3562)、17(TCH-3511)或32(TCH-3510)溶于ddH2O。健康6-10周大雌性Balb/cJ小鼠连续5天每天以口服方式给予5(TCH-3562)、17(TCH-3511)、32(TCH-3510)或ddH2O(60μg/200μl)。于第6天口服给予βG荧光前驱探针(pro-probe),荧光素2-β-D-葡糖苷酸(fluorescein di-β-D-glucuronide,FDGlcU)。经由体内光学影像系统侦测βG活性。结果显示口服给药17(TCH 3511)显著减少肠道中的荧光信号,显示17(TCH 3511)能有效地抑制肠道中βG活性(图5)。
实施例52 17(TCH 3511)对CPT-11诱发的腹泻与的抗癌活性的功效将17(TCH3511)投予小鼠以测试藉由细菌抑制剂17(TCH 3511)与CPT-11结合的肠道内βG抑制性是否可消除荷瘤小鼠(tumor-bearing mice)中CPT-11诱发的腹泻,并维持疗效。将CT26鼠结肠腺癌细胞(CT26murine colon adenocarcinoma cells)植入Balb/cJ小鼠皮下。形成实体肿瘤后,每天口服3mg/kg的17(TCH 3511)和腹腔内注射50mg/kg的CPT-11。腹泻的迹象是根据粪便形状及肛门周边染色。如图6A所示,17(TCH 3511)能减少CPT-11诱发的腹泻,不会影响CPT-11治疗的抗癌效果。
实施例53 17(TCH 3511)对于肠道中DMH诱发的癌变的影响将17(TCH 3511)投予至C57BL/6J-APCMIN/J小鼠,以确认是否预防DMH诱发的肠道损伤与癌变。将17(TCH 3511)以每周3次,每次口服3mg/kg,和DMH每周1次腹腔内注射30mg/kg一起投予。于8周治疗后,将小鼠处死,并检查肠道中的肿瘤。如图7所示,只有DMH治疗的群组中发现超过26个肿瘤,而有17(TCH 3511)的群组仅有6个肿瘤。因此,17(TCH 3511)能减少DMH诱发的肠道损伤与预防癌变。
