Progress in c-di-GMP inhibitors

Abstract:

The cyclic dinucleotide c-di-GMP is known as an important second messenger in bacteria, which controls various important cellular processes, such as cell differentiation, biofilm formation and virulence factors production. It is extremely vital for the development of new antibacterial agents by virtue of blocking c-di-GMP signal conduction. Current research indicates that there are three potential targets for discovering new antibacterial agents based on c-di-GMP regulated signal pathway, which are c-di-GMP synthases, c-di-GMP degrading enzymes and c-di-GMP receptors. Herein, we review small molecules that have been developed to inhibit c-di-GMP related enzymes and indicate perspectives of c-di-GMP inhibitors.
