BCRP-IN-1

Animal experiment:

Mice[1]To determine pharmacokinetic profile of (S)-ML753286 and Ko143 in vivo, Sprague-Dawley rats are administered 2.0 mg/kg or 20 mg/kg (S)-ML753286 or 2.0 mg/kg or 50 mg/kg Ko143, formulated in 0.5% HPMC/0.2% Tween80, via iv or po, respectively. After administration of (S)-ML753286 or Ko143, blood is obtained from all animals at predose and at 0.083, 0.25, 0.5, 1, 4, 8, and 24 h postdose. Approximately 200 μL of whole blood is collected from the jugular vein catheter of each animal into tubes containing the anticoagulant dipotassium ethylenediaminetetraacetic acid (K2EDTA) and is further processed into plasma at approximately 4°C[1].
