Hepatic clearance was predicted from liver microsomes incubations using the “in vitro t1/2 method.”9
Male Sprague–Dawley rats or female CD-1 mice were dosed intravenously with 1 mg/kg of 16 prepared in 60% PEG400/10% ethanol.
Compound 16 was administered PO at the indicated dose in 0.5% methylcellulose with 0.2% Tween 80 (MCT).
