Determination of a novel diacylglycerol acyltransferase 1 inhibitor, 2-[4-(4-{5-[2-phenyl-5-(trifluoromethyl) oxazole-4-carboxamido]-1H-benzo[d]imidazol-2-yl} phenyl) cyclohexyl] acetic acid (KR-69232) in rat plasma using liquid chromatography-tandem mass spectrometry and its application to a pharmacokinetic study

摘要

A liquid chromatography-tandem mass spectrometry method was developed and validated for the quantification of KR-69232, a diacyltransferase 1 inhibitor, in rat plasma. KR-69232 in the concentration range of 0.004-4μg/mL was linear. The intra-and inter-day precision and accuracy were acceptable (<20%). KR-69232 was stable under various storage and handling conditions. The method was applied successfully in a pharmacokinetic study of KR-69232 in rats.
