| Description |
GSK-114 is a highly selective, orally active TNNI3K inhibitor (IC50= 25 nM). GSK-114 shows a 40-fold selectivity for TNNI3K over B-Raf kinase (IC50= 1 µM). Cardiac troponin I-interacting kinase (TNNI3K or CARK) is a member of the tyrosine-like kinase family that is selectively expressed in heart tissue[1].

| In Vitro |
At a concentration of 1 µM, GSK114 demonstrated an affinity for seven other kinases: ACK1, B-Raf, GAK, MEK5, PDGFRB, STK36, and ZAK[2].

| In Vivo |
GSK-114 affords the best balance of specificity and pharmacokinetics, demonstrating useful oral exposure (poDNAUC=0.18, Cmax=130 ng/ml @ 2 mg/kg, t1/2=3.6 hr, rat Fu=20.2%)[1].
