ZM 39923 is an JAK1/3 inhibitor with pIC50 of 4.4/7.1, almost no activity to JAK2 and modestly potent to EGFR; also found to be sensitive to transglutaminase. ZM39923 inhibits the generation of AICD-FLAG and both Aβ40 and Aβ42 by purified γ-secretase in a concentration-dependent fashion with an approximate IC50 of 20 μM. ZM39923, a Janus kinase inhibitor,is the most potent inhibitors with IC(50) of 10 and 5 nM, respectively.ZM 39923 Breaks down in neutral buffer (t½ = 36 mins, pH 7.43, 25°C) to form ZM 449829.
