Biological Activity
AZD1080 is a potent and selective GSK3 inhibitor. AZD1080 inhibits recombinant human GSK3α and GSK3β with pKi (IC50) of 8.2 (6.9 nM) and 7.5 (31 nM), respectively.
In Vitro
AZD1080 shows selectivity against cdk2 (pKi=5.9; 1150 nM; 37-fold), cdk5 (pKi=6.4; 429 nM; 14-fold), cdk1 (pKi=5.7; 1980 nM; 64-fold) and Erk2 (pKi< 5; >10 μM; >323-fold). AZD1080 (at 10 μM) is also evaluated for pan-kinase selectivity and showed good overall selectivity versus 23 kinases, as well as against 65 different receptors, enzymes and ion channels in MDS Pharma screen (< 50% effect at 10 μM AZD1080). Concentration-dependent inhibition of tau phosphorylation is observed for AZD1080 (IC50=324 nM) and the non-selective reference GSK3 inhibitor LiCl (IC50=1.5 mM) indicating that AZD1080 is several orders of magnitude more potent than LiCl[1].
In Vivo
The pharmacokinetic analysis in blood after oral administration revealed that AZD1080 has a good oral bioavailability in rats (15-24%) with a half-life of 7.1 h, making AZD1080 attractive for further in vivo testing. The subchronic (3 days) oral treatment with AZD1080 at 4 or 15 μmol/kg significantly blocked the MK-801-induced memory deficit (AZD1080 vs. MK-801, p<0.05 at 4 μmol/kg and p<0.01 at 15 μmol/kg) in mice, raising the hypothesis that longer treatment may be required to prime the synapses to function effectively[1].
