Abstract
An HPLC procedure for the detection and quantitation of a new antidiabetic agent, N-(trans-4-isopropylcyclohexylcarbonyl)-D-phenylalanine (A4166), in dog plasma was developed. The drug and internal standard were extracted from plasma using a reversed phase C18 extraction column (Sep-pak). Separation was accomplished on a ERC-ODS-1161 reversed-phase column with a mobile phase of acetonitrile/0.1M phosphate buffer, pH 6.6 (30/70). Quantitation was achieved by monitoring the ultraviolet absorbance at 210 nm. A linear relationship between concentration and peak height ratio (A4166/internal standard) was obtained. The method has been successfully used for analysis of plasma samples from beagle dogs following oral administration of A4166.Keywords
