GSK180736A, developed as a Rho-associated, coiled-coil-containing protein kinase inhibitor, binds to GRK2(G protein-coupled receptor kinase 2) with logIC50 pf -6.6 (logIC50 -4.0 for GRK5 and >-3 for GRK1) ≥400-fold selective for GRK2 over both GRK1 and GRK5.

KRpep-2d is a K-Ras(G12D) selective inhibitory cyclic peptide with selectivity against wild-type (WT) K-Ras and the K-Ras(G12C) mutant. The IC50 value is 1.6 nM.  

Senexin A is a potent and selective inhibitor of CDK8 and its nearest relative, CDK19 with Kd values of 0.83 μM and 0.31 μM for CDK8 and CDK19 ATP site binding, respectively.

Chk2 Inhibitor II (BML-277) is an ATP-competitive inhibitor of Chk2 with IC50 of 15 nM.  It is 1000-fold more selective toward Chk2 serine/threonine kinase than for Chk1 and Cdk1/B kinases.

PTC-028 is an orally bioavailable compound that decreases BMI-1 levels by posttranslational modification.

SNS-314 Mesylate is a potent and selective inhibitor of Aurora A, Aurora B and Aurora C with IC50 of 9 nM, 31 nM, and 3 nM, respectively and less potent to Trk A/B, Flt4, Fms, Axl, c-Raf and DDR2.
