Synthesis Of Hydroxybenzylidene-Indolinones, Schiff Bases And N-Substituted Analogs And Their Effects On Bacterial Physiology., Catherine Eliana Cabrera, Neetu Dayal, Moloud Aflaki, Herman Sintim

The Summer Undergraduate Research Fellowship (SURF) Symposium

c-di-AMP is a global stress response regulator involved in some processes of biofilm formation and antibiotic resistance. It has become a candidate target for the development of new antibacterial treatments. Previous studies have shown that hydroxybenzylidene-indolinones can act as c-di-AMP synthase inhibitors. They also act as antibacterial and anti-biofilm inhibitors and re-sensitize resistant bacteria to methicillin and vancomycin. In this project, potent analogs of these compounds, including Schiff bases and N-substituted compounds, have been synthetized. The objective of this work is to explore the effect of these modifications on their biological activity. Base-catalyzed condensation and acid-catalyzed reactions were performed in …
