Telomerase is a relevant target for cancer therapy. A small 6-mer psoralen-containing oligonucleotide is shown to cause efficient photo-cross-linking to human telomere DNA by G-quadruplex formation. The small, photocontrolled oligonucleotide shows effective telomerase inhibition, both in vitro and in vivo, only when light irradiated. Data suggest that it is a promising agent for the treatment of cancer.
端粒酶是癌症治疗的一个相关靶点。研究表明,一种含有 6 个碱基的小 psoralen 寡核苷酸通过 G-四链体的形成导致人端粒 DNA 的有效光交联。这种小的、光控的寡核苷酸在体外和体内都显示出有效的端粒酶抑制作用,只有在光照下才会发生。数据表明,它是一种有前途的癌症治疗药物。
