important factor leading to multidrug resistance (MDR) in cancer treatments. Three subclasses of dual inhibitors of P-gp and BCRP were designed based on the active moieties of BCRP inhibitors, tyrosine kinase inhibitors, and P-gp inhibitors, of which compound 21 possessed low cytotoxicity, high reversal potency, and good lipid distribution coefficient. 21 also increased the accumulation of Adriamycin (ADM)
包括P-糖蛋白(P-gp)和乳腺癌抗性蛋白(BCRP)在内的ATP结合盒(ABC)转运蛋白的过表达是导致癌症治疗中多药抗性(MDR)的重要因素。基于BCRP抑制剂,酪氨酸激酶抑制剂和P-gp抑制剂的活性部分,设计了P-gp和BCRP双重抑制剂的三个亚类,其中化合物21具有低细胞毒性,高逆转效能和良好的脂质分布系数。21还增加了阿霉素(ADM)和米托蒽醌(MX)的积累,阻止Rh123流出,并且P-gp和BCRP的蛋白质表达没有变化。重要的是,共同管理21可以显着提高紫杉醇(PTX)的口服生物利用度。还表明,21可通过增加体内ADM的敏感性来显着抑制K562 / A02异种移植瘤的生长。总之,21有潜力克服由P-gp和BCRP引起的MDR,并提高PTX的口服生物利用度。
