In Vitro

TA-02 (5 μM) inhibits the phosphorylation of proteins downstream of p38α MAPK such as MAPKAPK2 and HSP27 during cardiogenesis. TA-02 at 5 μM concentration induces cardiogenesis, but also increases ATF-2 phosphorylation and MEF2C õexpression in contrast to what would be expected with a mechanism dependent on p38α MAPK inhibition.

TA-02 induces T/Brachyury whereas SB203580 addition increased MESP1 and T/Brachyury transcripts.

TA-02 significantly induces high NKX2-5 expression when applied between days 0-.

TA-02 is found to inhibit multiple targets with similar potency to p38α MAPK, such as p38α, p38β, JNK3, JNK2, CIT, CK1ε, DMPK2, JNK1, DDR1 CK1δ, MEK5, and ERBB2.

TA-02 and SB203580 reduce the nuclear TCF/LEF-1 driven transcription of luciferase similar to DKK-1.

TA-02 (5 nM-5 μM) inhibits p38 and increases the anti-inflammation effects of BDNF on inflammation in vitro.
