Kinetic solubility measured in PBR (pH = 7.4).
Microsomal intrinsic clearance (CLint); H = human; R = rat; M = mouse; cyno = cynomolgus monkey.
Liver microsomal metabolic stability, % of parent drug remaining after a 30 min incubation in the presence of the microsomes; HLM = human liver microsomes; RLM = rat liver microsomes; MLM = mouse liver microsomes; cyno LM = cynomolgus monkey liver microsomes.
CiPA hERG QPatch assay; compounds were tested (n = 2) in a five-point concentration–response study.
%PPB = plasma protein binding; H = human, R = rat, M = mouse.
