摘要:

三阴性乳腺癌是乳腺癌中最具侵略性的亚型, 经常对化疗药物产生耐药性。靶向该肿瘤相关基因的G-四链体结构, 有望开发出新的抗肿瘤药物。本研究靶向21-mer端粒G-四链体结构, 通过基于结构的高通量虚拟筛选, 得到可稳定端粒G-四链体的化合物VB07VC02。细胞毒性实验表明, VB07VC025 μM的浓度下对三阴性乳腺癌细胞具有抑制作用。这项研究表明基于结构的高通量虚拟筛选可以成功地发现靶向端粒G-四链体的化合物, 并利用此方法发现可抑制三阴性乳腺癌细胞的新化合物。

Abstract:

Triple-negative breast cancer is an aggressive subtype that frequently develops resistance to chemotherapy. It is expectedto develop new anti-tumor drugs through targeting the structure of G-quadruplexes of the genes associated with this tumor. In this work, by targeting the 21-mer telomere G-quadruplex structure, compounds VB07 and VC02 were identified to stabilize the telomere G-quadruplex through structure-based high-throughput virtual screening. Cell cytotoxicity assay showed that VB07 and VC02 exhibited inhibitory effect on triple-negative breast cancer cells at the concentration of 5 μM. This study showed that structure-based high-throughput virtual screening was able to successfully identify the proper compounds targeting the telomere G-quadruplex, which exhibited inhibitory effects against thetriple-negative breast cancer cells.
