Atuveciclib S-Enantiomer [2250279-81-1]

Atuveciclib S-Enantiomer (BAY-1143572 S-Enantiomer) is a potent and selective CDK9 inhibitor, which inhibits CDK9/CycT1 with an IC₅₀ of 16 nM.

IC50: 16 nM (CDK9/CycT1)^[1]

In comparison with Atuveciclib (BAY-1143572), Atuveciclib (BAY-1143572) S-Enantiomer reveals very similar in vitro properties, well within the limits of measurement accuracy; however, with multiple batches of Atuveciclib (BAY-1143572) S-Enantiomer there is a trend toward a slightly lower activity against CDK9 in the biochemical assay (IC₅₀ CDK9/CycT1: 16 nM) and antiproliferative activity against HeLa cells (IC₅₀: 1100 nM) ^[1].
