Abstract
化合物在制备调降Runx2表达试剂中的应用。经过模型证实,Fostamatinib、Regorafenib和褪黑素均可以显著下调Runx2的表达量,可用于Runx2高表达癌症的靶向治疗或实验用试剂。
Description
本发明涉及化合物的新应用,特别涉及化合物在制备调降RUNX2表达试剂、抗肿瘤药物等中的应用。
Runx2是一种公认的转录因子,对骨髓间充质干细胞向成骨细胞转化的过程起重要作用。体内外的研究表明,它可通过骨形态发生蛋白/Smads、丝裂原活化蛋白激酶信号通路等多种信号转导途径参与骨代谢,心血管系统的异位钙化,牙齿异常发育,肿瘤和器官纤维化等疾病的发生。Runx2在疾病的发生、发展以及预后的具体作用机制尚未完全明确,以Runx2为靶点治疗临床疾病或将成为研究热点。已有研究表明Runx2在多种肿瘤,如乳腺癌、肺癌、肺腺癌、前列腺癌、多发性骨髓瘤、乳腺恶性叶状肿瘤中高表达,直接影响肿瘤的进展。
肿瘤严重危害人们的身体健康,同时不同的肿瘤对同一药物也具有不同的反应。为提高疗效,减少副作用,基于肿瘤的表型,制订合理的用药方案,已经成为肿瘤治疗的共识。
福坦替尼(fostamatinib)是脾脏酪氨酸激酶(SYK)抑制药的活性代谢产物R406的前体药物,DrugBankID:DB12010,CAS号:945745-48-2,具有多种医学治疗作用,由美国Rigel
制药公司开发,用于血小板减少症的治疗,特别是对此前治疗方案缓解不佳的成年慢性免疫性血小板减少症(ITP)患者。
Regorafenib(瑞戈菲尼),DrugBankID:DB08896,CAS号:755037-03-7,是多种与细胞膜结合的胞内激酶的小分子抑制剂,这些激酶与正常细胞功能和病理过程,例如肿瘤发生,肿瘤血管生成和肿瘤微环境的维持相关。在体外生化或细胞分析中,雷戈非尼或其主要人类活性代谢产物M-2和M-5抑制RET,VEGFR1,VEGFR2,VEGFR3,KIT,PDGFR-alpha,PDGFR-beta,FGFR1,FGFR2,TIE2,在regorafenib浓度达到临床上已达到的DDR2,TrkA,Eph2A,RAF-1,BRAF,BRAFV600E,SAPK2,PTK5和Abl。在体内模型中,雷戈非尼在大鼠肿瘤模型中显示出抗血管生成活性,并在几种小鼠异种移植模型(包括某些人结肠直肠癌)中显示出对肿瘤生长的抑制以及抗转移活性。Regorafenib的副作用比较大,已批准的临床用途为用于治疗既往接受过氟尿嘧啶、奥沙利铂和伊立替康为基础的化疗,以及既往接受过或不适合接受抗VEGF治疗、抗EGFR治疗(RAS野生型)的转移性结直肠癌患者;用于治疗既往接受过甲磺酸伊马替尼及苹果酸舒尼替尼治疗的局部晚期的、无法手术切除的或转移性的胃肠间质瘤患者;用于治疗既往接受过索拉非尼治疗的肝细胞肝癌。
褪黑素(Melatonin,MT)是由脑松果体分泌的激素之一,DrugBankID:DB01065,CAS号:73-31-4。又称为松果体素、褪黑激素、褪黑色素。MT有强大的神经内分泌免疫调节活性和清除自由基抗氧化能力。
开发已有化合物的新应用,具有非常重要的意义。

实验步骤:将小鼠随机分为两组,实验组(fostamatinib)与对照组(mock),每日实验前精确称取一定量的fostamatinib,溶解于0.5%CMC(硝甲基纤维素)中,充分吹打均匀为均一的悬液,配制浓度为4mg/ml,现用现配。按照每只小鼠100ul/10g的注射量进行腹腔注射,连续注射4天,最后一次注射后48小时取小鼠肝脏组织,抽提RNA,通过实时荧光定量PCR(qPCR)方法检测RUNX2的mRNA表达水平。实验如果如图6所示。可以看出,fostamatinib可以显著降低RUNX2的mRNA表达水平,具有抗肿瘤作用。
