Multidrug resistance (MDR) occurring during cancer chemotherapy is a major obstacle for effectiveness and response to therapy and is often caused by ATP-binding cassette (ABC) efflux transporters. Belonging to the family of ABC transporters, breast cancer resistance protein is getting more and more in the spotlight of research. As a strategy to overcome MDR, inhibitors of ABC transporters were synthesized
在癌症化疗期间发生的多药耐药性(MDR)是影响疗效和对治疗产生反应的主要障碍,并且通常由ATP结合盒(ABC)外排转运蛋白引起。属于ABC转运蛋白家族的乳腺癌抗性蛋白越来越受到研究的关注。作为克服MDR的策略,合成了ABC转运蛋白抑制剂,可与抑制细胞生长的药物联合使用。为此目的,合成了2,4-二取代的吡啶并嘧啶衍生物。研究证实了良好抑制剂的三个关键特征:低内在的细胞毒性以及对ABCG2的高效力和选择性。对于选定的化合物,阐明了与ABCG2的相互作用,并研究了它们对ATPase活性和构象敏感性5D3抗体结合的影响。与伊立替康和米托蒽醌的活性代谢产物合用时,它们具有逆转MDR的能力。
