Products Often Used Together with GSK3685032

SGI-1027

In MV4-11 cells, it is enzymatically less potent and shows decreased cell-growth inhibition compared to GSK3685032.

RG108

It and RG108 non-covalently bind to DNA methyltransferases (DNMTs) active sites, inducing demethylation, transcriptional activation, and cancer cell growth inhibition.

CM272

Both GSK3685032 and CM272 strongly inhibit DNMT1 with nanomolar activities, but it is stronger than CM272.

2'-Deoxy-5-Fluorocytidine

It and 2'-Deoxy-5-Fluorocytidine both inhibit DNMT and induce DNA damage.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	DNMT1 ^[1] (Cell-free assay) 0.036 μM(ic50)
In vitro	GSK3685032 engages DNMT1 specifically in both biochemical and cellular contexts, and its selective inhibition of DNMT1 slows cancer cell growth. This compound also induces DNA hypomethylation and gene activation.^[1]
In vivo	In mice, GSK3685032 exhibits low clearance, a moderate volume of distribution, and a blood half-life >1.8 h with dose-proportional exposure from 1 to 45 mg/kg, higher doses of this compound show reductions in neutrophils and red blood cells, these doses showing markedly greater DNA hypomethylation and tumor growth inhibition/regression.^[1]
