3BrB-PP1 is an ATP-competitive analog that exhibits specific inhibitory activity towards protein kinase. It is effective in inhibiting protein kinase with mutations in the ATP-binding pocket, specifically the mutation of Thr97 within Sty1's ATP-binding pocket.
EIPA hydrochloride also inhibits Na+ H+-exchanger (NHE) and macropinocytosisEIPA hydrochloride (L593754 hydrochloride) is a TRPP3 channel inhibitor with an IC50 of 10.5 μM.
Okadaic acid ammonium salt, a marine toxin, serves as an inhibitor of protein phosphatases (PP), displaying a higher affinity for PP2A (IC 50 =0.1-0.3 nM) alongside inhibitory effects on PP1 (IC 50 =15-50 nM), PP3 (IC 50 =3.7-4 nM), PP4 (IC 50 =0.1 nM), and PP5 (IC 50 =3.5 nM), but does not affect PP2C. By inhibiting PPs, this compound promotes protein phosphorylation and acts as a tumor promoter. Additionally, it is involved in inducing tau phosphorylation.
CBP p300-IN-8 is a potent inhibitor of the CBP P300 family of bromodomains . CBP p300-IN-8 inhibits CBP ( IC 50 =0.01-0.1 μΜ) and BRD4 ( IC 50 =1-1000 μΜ) activity.
