Sodium N-8-(2-hydroxybenzoyl)aminocaprylate (SNAC) is a well-known penetration enhancer widely used in commercial applications. This study aims to broaden its properties through a novel strategy of converting it into its phenolate salts. The objective is to investigate the synthesis of SNAC phenolate salts, specifically SNAC-choline (SNAC-CH), SNAC-sodium (SNAC-Na), and SNAC-phosphatidylcholine (SNAC-PC), and to explore their potential application in improving the oral absorption of semaglutide.
