A diversity-oriented rhodamine library for wide-spectrum bactericidal agents with low inducible resistance against resistant pathogens

open access: yesNature Communications, 2019
Preparation of xanthene-containing compounds has been limited due to structural bias existing methods pose. Here, the authors developed a mild, diversity-oriented method for rhodamines synthesis, leading to the finding of compounds with antibacterial ...
