Description

Siderophores are molecules that act as iron carriers in bacteria. As they sequester iron from the environment and penetrate bacterial cells through active transporters, they can bypass the porin-mediated transportation in Gram-negative bacteria. Therefore, conjugating antibiotics that lacks the ability to pass through porins to siderophores and forming “sideromycins” has been proven as a way to battle antibiotic resistance in Gram-negative bacteria. My research will focus on synthesizing two siderophores, catenulobactin B and talarazine A as well as their analogs and exploring their potential to synthesize sideromycins. These molecules will be synthesized in a modular way and their cytotoxicity, ability to penetrate bacteria, and metal chelation will be studied thoroughly.
