Description
优先权声明
本申请案要求申请日为2012年3月8日,申请号为201210060269.X,发明名称为“一组苯-噁唑基衍生物及其制备方法和作为IMPDH抑制剂的相关应用”的中国临时专利申请案的优先权,其说明书是以引用的方式全部并入本文中。
技术领域
本发明涉及一组苯-噁唑基衍生物及其制备方法,还涉及该苯-噁唑基衍生物作为次黄嘌呤核苷酸脱氢酶(IMPDH)抑制剂的相关应用,属于生物医药领域。
背景技术
次黄嘌呤核苷酸脱氢酶(inosinemonophosphatedehydrogenase,IMPDH)是嘌呤核苷酸生物合成的关键酶,依赖烟酰胺腺嘌呤二核苷酸(NAD),催化鸟嘌呤核苷酸从头合成的限速步骤,将次黄嘌呤核苷酸(IMP)氧化为黄嘌呤核苷酸(XMP)。XMP随后被GMP合成酶作用转化为GMP。这是细胞生长和增殖的关键。除了少数原生动物寄生虫外,IMPDH/GMP在每一个生物体内存在。抑制IMPDH将导致抑制增殖和很多重要的胞内反应。人的IMPDH包括两种,I型(hIMPDH1)和II型(hIMPDH2),具有84%的同源性。研究表明,hIMPDH2在增殖细胞内选择性上调,在激活的外周淋巴细胞中显著表达;在多数静态细胞中hIMPDH1表达占主导,hIMPDH1也被证明在血管生成中发挥关键作用。因此,IMPDH成为发现抗病毒、抗癌、免疫抑制等药物的重要靶点。
IMPDH抑制剂基于其结合活性中心可分为IMP点位和NAD点位两类。所有抑制作用的机制是通过阻断或通过IMP和NAD的点位构像改变,可以干扰甚至终止底物活性过程。
可逆的和不可逆的IMP点位抑制剂中包括一些化合物及其单磷酸物,如利巴韦林(HagerPW,BiochemPharmacol1995;49(9):1323-1329),3-脱氮鸟苷(3-deazaguanosine)(CookPD,JAmChemSoc1976,98(6):1492-1498.;StreeterDG,BiochemPharmacol1976,25(21):2413–2415.),咪唑立宾(mizoribine)(HagerPW,BiochemPharmacol1995;49(9):1323–132;KerrKM,Biochemistry1997,36(43):13365–13373.),6-氯嘌呤核苷(6-chloropurineriboside)(AntoninoLC,Biochemistry1994,33(7):1760–1765.)和2-乙烯肌苷(2-vinylinosines)(PalS,BioorgMedChem2002,10(11):3615–3618.;NairV,ClinMicrobiolRev2001,14(2):382–397.)等。利巴韦林已用于治疗呼吸道合胞病毒感染,与α-干扰素合用治疗丙肝。咪唑立宾已被用于批准器官移植排斥、类风湿关节炎、原发性肾病综合征、狼疮性肾炎、皮肌炎和自身免疫性皮肤病。与IMPDH复合物X射线晶体结构表明,6-氯嘌呤核苷磷酸或2-乙烯肌苷磷酸,均表现抑制剂与酶Cys331共价键的形成。
以靶点为NAD结合点位的抑制剂,如噻唑羧胺核苷(tiazofurin)(DeClercqE.ClinMicrobiolRev2001,14(2):382–397.;MinakawaN,CurrMedChem1999;6(7):615–628.)是NAD+的非竞争性IMPDH抑制剂,具有抗增殖和抗病毒活性,它的硒类似物显示体内外抗肿瘤活性。硒唑核苷(selenazole-nucleoside)(JayaramHN,BiochemPharmacol1983;32(17):2633–2636.;StreeterDG,BiochemlBiophysResCommun1983,115(2):544–550.)体外有抗DNA和RNA病毒活性。苯甲酰胺核苷通过其活性代谢物酰胺腺嘌呤二核苷酸显示其抑制活性,与IMPDH催化过程的NAD+竞争。
霉酚酸(Mycophenolicacid,MPA)不需要激活且适合在NAD结合位点的烟酰胺端。通过基于MPA等结合模式的结构基础的药物设计,已经得到了系列IMPDH抑制剂,如通过脲类连接的化合物VX-497(Merimepodib),VX-148和AVN944等(LizbethHedstrom.Chem.Rev.2009,109,2903–2928),进一步结构修改产生了含有噁唑吲哚、氰基吲哚、吡啶吲哚、异喹啉和吖啶酮等结构类型的IMPDH抑制剂。
MPA能够诱导淋巴细胞坏死,抑制肿瘤细胞生长。一系列霉酚酸腺嘌呤核苷酸,显示了更强的抗白血病效果和诱导细胞分化的能力,是有前景的治疗慢性粒细胞白血病的候选药物(SonjaBBraun-Sand,FutureMed.Chem.2010,2(1):81-92;RejmanD,JMedChem,2006,49(16):5018-5022.)。SAHA(Suberoylanilidehydroxamicacid)能够同时抑制IMPDH和HDAC,用于治疗皮肤T细胞淋巴瘤(LiqiangChen,JMedChem,2007,50,6685-6691)。AVN944是特异性的非竞争性IMPDH抑制剂,有望成为有前景的前列腺癌治疗药物。AVN944与吉西他滨合用用于胰腺癌的治疗已进入临床试验(FlorykD,IntJCancer,2008,123(10):2294-2302.)。
VX-497是一个抗病毒候选化合物,在对乙型肝炎病毒、人巨细胞病毒、呼吸道合胞病毒、1-型单纯疱疹病毒、脑心肌炎病毒、委内瑞拉马脑脊髓炎病毒的体外细胞实验中,VX-497的抗病毒活性均强于利巴韦林。VX-497与干扰素合用的实验中,也显示出比利巴韦林与干扰素合用更好的效果,其对丙肝的治疗作用已进入二期临床试验(MarklandW,AntimicrobAgentsChemother2000,44,(4)859–866)。
IMPDH抑制剂还应用于免疫抑制、抗菌和抗寄生虫药物的研究。MPA的前药霉酚酸酯应用于实体器官的移植。VX-497、VX-148等还用于免疫抑制疾病的治疗研究,有希望成为理想的侯选药物。
在以IMPDH为靶点的药物研究中,本发明证实,一系列新的具有苯-噁唑基的衍生物具有很强的IMPDH抑制活性,并显示有抗病毒(COX-B3)作用、抗肿瘤作用(肝癌细胞、人肺腺癌细胞)作用和免疫抑制作用。本发明所述化合物及其作用,迄今为止未见有国内外相关文献的报道。发展针对IMPDH的新药物将为临床提供更有效的新型抗病毒、抗癌和免疫抑制等治疗药物。

发明化合物对HCV、流感等也呈现强抑制活性。
IMPDH是嘌呤生物合成的关键酶,它将次黄嘌呤核苷酸IMP氧化为黄嘌呤核苷酸XMP,然后,XMP在GMP合成酶的催化下生成GMP。鸟嘌呤核苷酸对于DNA和RNA的合成是重要的酶底物,在细胞的生长分化、凋亡及在细胞信号传导中具有重要作用。抑制IMPDH将导致鸟嘌呤核苷酸缺乏,DNA合成受阻,使细胞静止于G1期,IMPDH的催化反应与细胞增殖有密切关系。因此,IMPDH抑制剂具有广谱抗肿瘤活性。
根据以IMPDH为靶点的抗肿瘤药物研究进展,本发明采用人肝癌细胞HepG2,测定了发明化合物的抑制人肝癌细胞HepG2活性;采用人肺腺癌细胞A549,测定了发明化合物对人肺腺癌细胞A549抑制作用,测定结果见表5:
