Stauprimide is a staurosporine analog that promotes embryonic stem cell (ESC) differentiation. Stauprimide is a non-broad spectrum inhibitor that binds to the MYC transcription factor NME2 and blocks its nuclear localization in ESCs, which results in down-regulation of MYC transcription [1] .
Stauprimide (10 μM; 6 hours) suppresses MYC transcription in the majority of cell lines tested with an EC
50
range of 30 nM-8 μM, and decreases MYC levels between 15% to over 90%
[1]
.
Stauprimide (2-8 μM; 24-72 hours) down-regulates MYC leads to the inhibition of cell proliferation in vitro with an IC
50
of 780 nM in RXF 393 cells
[1]
.
Stauprimide (5 μM; 3 hours) suppresses MYC Transcription by decreasing NME2 Nuclear Translocation
[1]
.
Stauprimide (4-10 μM; 6 hours) acts with different EC
50
s and with different degrees of maximal MYC mRNA down-regulation in different cell lines
[1]
.

Result: | Suppressed MYC transcription in KG1A cells with an EC 50 of 400±50 nM and a suppression of 90%; CA46 cells were resistant to stauprimide. |
Stauprimide (oral administration; 50 mg/kg; once daily; 30 days, 55 days) blocks tumor growth, reduces MYC protein levels in xenograft mouse with RXF 393 or CAKI-1 cells and inhibits MYC transcription in the RXF 393 tumor [1] .
