Negative Control Compounds

SGC-CLK-1
Notes: SGC-CLK-1N was tested in the Discoverx panel and no kinases had PoC<45. The negative control was sent to Eurofins for testing in enzyme assays for CLKs and typical CLK inhibitor off targets, showing no inhibition.

Cellular Use Rating
This probe has potent activity against the CLK family of CMGC kinases (1,2,4). It seems to be a good probe for these targets in cells. However, there is no data provided for the most related kinases,...
