The research focused on the synthesis and evaluation of derivatives of Esculentoside A (EsA), a triterpene saponin with notable anti-inflammatory properties and selective inhibitory activity towards cyclooxygenase-2 (COX-2). The purpose was to optimize EsA's structure to enhance its biological activity while reducing its haemolytic toxicity. A series of derivatives were synthesized by converting the C-28 carboxylic acid group of EsA into amides using HOBt and DCC in DMF, followed by the addition of various amines (aliphatic, aromatic, and amino acid esters). The study concluded that introducing aromatic rings significantly improved COX-2 inhibitory activity, with compound 23 exhibiting higher inhibitory rates than both EsA and Celecoxib, while also demonstrating lower haemolytic toxicity. The findings suggest that structural modifications of EsA can lead to more effective COX-2 inhibitors with reduced side effects.
