| Bioactivity | CGP52411 (DAPH) is a high selective, potent, orally active and ATP-competitive EGFR inhibitor with an IC50 of 0.3 μM. CGP52411 blocks the toxic influx of Ca2+ ions into neuronal cells, and dramatic inhibits and reverses the formation of β-amyloid (Aβ42) fibril aggregates associated with Alzheimer's disease[1][2]. | ||||||||||||
| Invitro | CGP52411 (DAPH; 0-100 μM; 90 minutes; A431 cells) treatment inhibits autophosphorylation and c-src autophosphorylation in vitro in a dose-dependent manner with IC50s of 1 μM and 16 μM, respectively. CGP52411 treatment also shows a concentration-dependent reduction in tyrosine phosphorylation of p185c-erbB2 with an IC50 value of 10 μM[1].CGP52411 (DAPH) inhibits c-src kinase with an IC50 value of 16 μM. CGP52411 inhibits PKC isozymes isolated from porcine brain with an IC50 of 80 μM. CGP52411 inhibits conventional PKC isozymes (cPKCs α, β-1, β-2, and γ) but not nonconventional PKC isozymes (nPKCs δ, ε, and ζ) or atypical PKC isozymes (aPKC η)[1].
