IC50& Target | |
体外研究 (In Vitro) | GSK-3685032 (6 days) has cell growth inhibition of majority cancer cell lines, with a median growth IC50value of 0.64 μM[1]. GSK-3685032 (0.1-1000 nM, 1-6 days) exhibits growth inhibition after 3 days, with decreasing growth IC50throughout a 6 d time course[1]. GSK3685032 (10-10000 nM, day 4) dose-dependently increases the immune-related gene transcription[1]. GSK3685032 (3.2-10,000 nM, 2 days) inhibits DNMT1 protein expression[1]. GSK3685032 induces DNA hypomethylation and gene activation[1].
