초록

A new tadalafil analogue was found in a commercial dietary supplement for enhancing sexual performance. The compound was detected by a high-performance liquid chromatography-diode array detector (HPLC-DAD). The analogue was isolated using semi-preparative HPLC, and its accurate mass was established by two LC-high-resolution-mass spectrometers (LC-HRMS). The structure was determined by nuclear magnetic resonance (NMR) spectroscopy. The accurate mass of the compound corresponded to a molecular formula of C24H23N3O4. The compound was identified as a structural analogue of tadalafil in which the N-methyl group of tadalafil was replaced with an N-isopropyl group. We have named the new analogue isopropylnortadalafil and it is first reported herein.
