General description
A potent, cell-permeable, reversible γ-secretase inhibitor that preferentially appears to inhibit the secretion of Aβ1-40 (>90%) over Aβ1-42 (~15%). Aβtotal IC50 ~ 15 M; Aβ1-40 IC50 ~ 22 M; Aβ1-42 IC50 >50 M in CHO cells stable transfected with the cDNA encoding βAPP695.
A potent, cell-permeable, reversible inhibitor of γ-secretase that is reported to preferentially inhibit the secretion of Aβ1-40 (>90%) vs. Aβ1-42. IC50 = ~15 µM for Aβtotal; ~22 µM for Aβ1-40; and >50 µM for Aβ1-42 in CHO cells stably transfected with the cDNA encoding βAPP695. Reported to be about 10-fold more potent than Z-Val-Phe-CHO [MDL 28170 (Cat. No. 208722)].
