It is an object of the present invention to provide an ABC transporter inhibitor whereby the multi-drug resistance against anticancer drugs caused by amplification and expression of MDR1 gene, which is the most serious problem in chemotherapy for cancer, or the resistance against antifungal agents in mycotic diseases can be overcome. The present invention relates to an ABC transporter inhibitor containing enniatin or its analog as the active ingredient. The ABC transporter inhibitor of the present invention, being capable of inhibiting transport/excretion of a drug, especially an anticancer drug or an antifungal agent, from inside to outside of cells, is useful in preventing, suppressing, or inhibiting acquisition of resistance against various drugs.
本发明的目的是提供一种 ABC 转运体
抑制剂,从而克服因 MDR1
基因的扩增和表达而引起的对抗癌药物的多重耐药性(这是癌症化疗中最严重的问题)或霉菌病中对抗真菌药物的耐药性。本发明涉及一种以烯啶或其类似物为活性成分的 ABC 转运体
抑制剂。本发明的ABC转运体
抑制剂能够抑制药物,特别是抗癌药物或抗真菌药物从细胞内向细胞外的转运/排泄,因此可用于预防、抑制或抑制获得对各种药物的抗药性。
