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 acts as a cardiogenic inhibitor.
TA-02, an analog of SB 203580 (HY-10256), is a p38 MAPK inhibitor with an IC50 of 20 nM. TA-02 especially inhibits TGFBR-2. TA-02 exhibits similar cardiogenic properties as SB 203580 and SB 202190 (HY-10295)[1].
