Compound 3 vs. Compound 8: primary activity and <i>in vitro</i> ADME profiling.

aIC50 values (nM) were obtained as described in the Methods section. bMetabolic stability is reported as percentage of the original compound, at 1 µM, that remained after the incubation with liver microsomes from different species for 15 minutes. cIC50 values are reported as µM and were calculated in duplicate from radioligand binding assays using [3H]-astemizole. dPe values, reported as 10-6 cm/s were calculated by LC/MS/MS after 4 hours of incubation at 2 µM.
