生物活性

GSK-3685032 is a non-time-dependent, noncovalently, first-in-class reversible DNMT1-selective inhibitor, with an IC50 of 0.036 μM. GSK-3685032 induces robust loss of DNA methylation, transcriptional activation, and cancer cell growth inhibition.

体外研究

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

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
