Novel thiazolidine-4-carboxylic acid derivatives: synthesis and inhibitory effects against influenza A.

This study explored the synthesis and evaluation of novel neuraminidase (NA) inhibitors, focusing on thiazolidine-4-carboxylic acid derivatives to combat influenza. The synthesized compounds were evaluated for their NA inhibitory activity and assessed against Influenza A (H7N3) using hemagglutination inhibition (HAI) assays. Molecular docking studies were also conducted to support the experimental findings. Compounds 4a, 4b, and 6a demonstrated potent NA inhibitory activity. While all compounds showed moderate HAI activity compared to Oseltamivir, 4a and 8a exhibited strong potency with low Mean MIC values against the H7N3 strain. These findings suggest that the thiazolidine derivatives hold potential as novel inhibitory agents against influenza. Future research will focus on assessing their toxicity and safety profiles, paving the way for the development of effective and safer NA inhibitors.
