Dicoumarol is a reductase inhibitor possessing anticoagulant properties. Dicoumarol also aids in apoptosis induction via stimulation of SAPK-JNK and NF-κB pathway blocking. This has no effect on the phosphorylation of P38 or activation of AKT. Additionally, Dicoumarol may act to block brefeldin A-dependent mono-ADP-ribosylation in vitro and Golgi disassembly in living cells. Dicoumarol is an inhibitor of NQO1. Dicoumarol is a potent inhibitor of NADH:quinone oxidoreductase (NQO1), exhibiting competitive inhibition with IC50 values of 2.6 nM in the absence of 2 μM BSA, and 404 nM in its presence. This compound demonstrates significant antiproliferative effects on MIA PaCa-2 pancreatic and HCT116 colon carcinoma cells, with IC50 values of 52 μM and 19 μM, respectively, following a 96-hour incubation period.

How to dissolve Dicoumarol in DMSO quickly? I dissolved ~16 mg in 1 ml DMSO but it always precipitate although I already tried shaking and vortexing it.

Asked by: opik
Thank you for your question. We have not tested this in DMSO, but one suggestion would be to try gentle warming to bring it into solution.
