1 In addition, the Abl kinase inhibitor imatinib mesylate (Gleevec, or STI571), which targets the ATP-binding site of Abl and several other tyrosine kinases, potently reduces Abeta production in the N2a cell-free system and in intact N2a cells. Imatinib Mesylate amyloid beta (A4) precursor protein Mus musculus
2 In addition, the Abl kinase inhibitor imatinib mesylate (Gleevec, or STI571), which targets the ATP-binding site of Abl and several other tyrosine kinases, potently reduces Abeta production in the N2a cell-free system and in intact N2a cells. Imatinib Mesylate amyloid beta (A4) precursor protein Mus musculus
3 Both STI571 and a related compound, inhibitor 2, also reduce Abeta production in rat primary neuronal cultures and in vivo in guinea pig brain. Imatinib Mesylate amyloid beta (A4) precursor protein Mus musculus
4 Furthermore, production of Abeta and its inhibition by STI571 were demonstrated to occur to similar extents in both Abl-/- and WT mouse fibroblasts, indicating that the effect of STI571 on Abeta production does not involve Abl kinase. Imatinib Mesylate amyloid beta (A4) precursor protein Mus musculus
5 Furthermore, production of Abeta and its inhibition by STI571 were demonstrated to occur to similar extents in both Abl-/- and WT mouse fibroblasts, indicating that the effect of STI571 on Abeta production does not involve Abl kinase. Imatinib Mesylate amyloid beta (A4) precursor protein Mus musculus
6 The efficacy of STI571 in reducing Abeta without affecting Notch-1 cleavage may prove useful as a basis for developing novel therapies for Alzheimer"s disease. Imatinib Mesylate amyloid beta (A4) precursor protein Mus musculus
