accumulation of many unrelated chemotherapeutic agents leading to multidrug resistance (MDR). A series of 31 benzamide and phenyltetrazole derivatives with amide and urea linkers has been synthesized to serve as potential BCRP inhibitors in order to overcome BCRP-mediated MDR. The target derivatives were tested for their cytotoxicity and reversal effects in human non-small cell lung cancer cell line
乳腺癌抗性蛋白(BCRP / ABCG2)是一种72 kDa的质膜转运蛋白,是ABC转运蛋白超家族的成员。BCRP表达增加导致外排增加,因此减少了许多不相关的化学治疗剂的细胞内积累,从而导致了多药耐药性(MDR)。为了克服BCRP介导的MDR,已合成了31种具有酰胺和脲连接基的苯甲酰胺和苯基四唑衍生物,用作潜在的BCRP抑制剂。使用MTT测定法测试了目标衍生物在人非小细胞肺癌细胞系H460和米托蒽醌抗性细胞系H460 / MX20中的细胞毒性和逆转作用。在苯甲酰胺系列中,化合物6和7在10 µM的浓度下,抗折叠性分别为1.51和1.62,这与已知的BCRP抑制剂FTC相似。化合物27和31是具有酰胺接头的苯基四唑系列中最有效的类似物,在10 µM浓度下的耐折叠性分别为1.39和1.32。对于具有脲连接基的苯基四唑系列,38的抗折叠性为1.51,与FTC相似,是该系列中最有效的化合物。目标化
