Atuveciclib S-Enantiomer (BAY-1143572 S-Enantiomer) is a potent and selective CDK9 inhibitor, which inhibits CDK9/CycT1 with an IC50 of 16 nM. 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) . Atuveciclib (BAY-1143572) S-Enantiomer exhibits blood/plasma ratios of about 1. Relative to Atuveciclib (BAY-1143572), Atuveciclib (BAY-1143572) S-Enantiomer reveals very similar rat PK properties in vivo (CLb: 1.2 L/kg per hour, Vss: 1.2 L/kg, t1/2: 0.6 h, F: 53 %). .
