Background:

TA-01 is a potent CK1 and p38 MAPK inhibitor, with IC50s of 6.4 nM, 6.8 nM, 6.7 nM for CK1ε, CK1δ and p38 MAPK, respectively.
TA-01 is a potent CK1 and p38 MAPK inhibitor, with IC50s of 6.4 nM, 6.8 nM, 6.7 nM for CK1ε, CK1δ and p38 MAPK, respectively. TA-01 (5 μM) is not cytotoxic, completely inhibits cardiogenesis, but induces cardiogenesis at lower concentration[1].
