Description
技术领域
本发明公开一种双靶向BRD4-CK2小分子抑制剂以及在肿瘤治疗中的应用,属于抗肿瘤药学技术领域。
背景技术
据国际癌症研究中心最新统计表明,全球每年约有170万女性被确诊为乳腺癌,且导致50万患者死亡。在我国,近年来乳腺癌呈现大约4%的高速率增长,且有进一步年轻化的趋势,严重威胁女性的健康。三阴性乳腺癌(TNBC)是指雌激素受体(ER),孕激素受体(PR)和人表皮生长因子受体2(Her-2)均为阴性的乳腺癌,占所有乳腺癌病理类型的15-20%,具有极高的致死率。TNBC由于其特殊的生物学行为和临床病理特征,其预后比其他类型的乳腺癌差,同时具有恶性程度高,发病年龄更加年轻,侵袭性高,容易复发转移等特点。由于ER,PR不表达,并缺乏HER2的扩增,TNBC通常没有公认的分子治疗靶标,临床上缺乏有效的治疗药物和治疗策略。
目前临床上常用的TNBC治疗手段仍然是手术和常规的全身细胞毒化学治疗,治疗效果并不理想,预后依然很差。Bromodomain containing protein 4(BRD4)在癌症和其他慢性疾病中具有吸引力的表观遗传靶点。越来越多的BRD4抑制剂被发现并用于TNBC的治疗,但耐药性的出现是限制BRD4抑制剂临床应用最主要的难题。蛋白激酶casein kinase 2(CK2)是介导BRD4磷酸化和去磷酸化进而发挥作用的分子开关。此外,CK2抑制也会导致多药耐药细胞对已知药物摄取的增加。因此,设计合成双靶向BRD4-CK2的抑制剂或许可以为TNBC的治疗提供新的方案。
