...) and in a B-lymphocyte cell line with IC 50 values of 300 and 6 nM respectively. AZD8797 also prevented G-protein activation in a [ 35 S]GTPγS (guanosine 5′-[γ-thio]triphosphate) accumulation assay. In contrast, dynamic mass redistribution (DMR) experiments revealed a weak G αi -dependent AZD8797 agonism...
