MedKoo CAT#: 561277

CAS#: 789-61-7

Description: 6-thio-dG is a telomerase substrate precursor with anticancer activities. In A549 lung cancer cell-based mouse xenograft studies, 6-thio-dG caused a decrease in the tumor growth rate superior to that observed with 6-thioguanine treatment. In addition, 6-thio-dG increased telomere dysfunction in tumor cells in vivo.
