2018年饶燏课题组与生科院刘万里课题组合作在《Cell Research》期刊首先报道了通过构建新型BTK蛋白高效降解剂,克服了临床上B细胞恶性肿瘤由于BTK蛋白突变引起的对临床一线药物ibrutinib的耐药性,新策略的靶向选择性远优于ibrutinib,能够避免ibrutinib产生的严重副作用。随后,饶燏课题组与北京大学肿瘤医院朱军课题组,以及刘万里课题组合作在血液学国际著名期刊《白血病》(Leukemia)在线发表了最新研究成果《利用PROTAC技术降解多种突变型BTK蛋白克服ibrutinib耐药的非霍奇金淋巴瘤的潜在治疗方案》(Degradation of Bruton’s tyrosine kinase mutants by PROTACs forpotential treatment of ibrutinib-resistant Non-Hodgkin lymphomas)。通过构建新型高溶解度的BTK蛋白高效降解剂,成功高效的降解多种临床相关的突变型BTK蛋白,克服了临床上非霍奇金淋巴瘤由于BTK蛋白突变引起的对临床一线药物ibrutinib的耐药性。更为重要的是,新策略克服肿瘤耐药的有效性得到了体内实验的验证。
1)新合成的PROTAC小分子既能够选择性地结合到BTK蛋白,又能够选择性地结合到E3泛素化连接酶,并且还能够拉近两蛋白在空间上的距离,起到泛素化降解BTK的目的;
