17-AAG又称为Tanespimycin、CP 127374,是一种有效的Hsp90抑制剂(IC50=5 nM)。17-AAG作用于肿瘤细胞Hsp90的亲和力比作用于正常细胞中Hsp90亲和力高100倍,另外,17-AAG还能抑制Akt活化及HER2、ErbB2表达。17-AAG抑制多种癌细胞生长,如神经胶质瘤细胞等,在体内外表现出明显的抗肿瘤活性。另外,17-AAG与大量抗癌药如UCN-01,依托泊苷(etoposide),顺铂(cisplatin)显示协同作用。
17-AAG是格尔德霉素(geldanamycin)的半合成类似物,具有更低的体内毒性和更强的稳定性,目前已用于乳腺癌等疾病Phase II研究阶段。
