摘要: We previously reported that shikonin could circumvent drug resistance mediated by P-gp, Bcl-2 and Bcl-xL, induction of necroptosis. Here, we show the naturally-occurring analogues (deoxyshikonin, acetylshikonin, isobutyrylshikonin, beta,beta-dimethylacrylshikonin, isovalerylshikonin, alpha-methyl-n-butylshikonin) bypass not only Bcl-2, but also two additional important drug-resistant factors MRP1 BCRP1, The results strengthen previous findings necroptotic a broad spectrum cancer resistance.
