  • Melanin-inspired antimicrobial
    Patent number: 11730717
    Abstract: Herein, is taught a Eumelanin-inspired antimicrobial capable of overcoming methicillin resistant Staphylococcus aureus (MSRA) and Enterococcus faecalis. By ligating quaternary ammonium functionalized “arms” on to a Eumelanin-inspired indole, with intrinsic antimicrobial activity, a cell wall destroying antimicrobial agent was prepared. It also has antifungal effects against Candida albicans. Further, Eumelanin-inspired phenyleneethynylene (EIPE) derivatives EIPE-1 and EIPE-HCl are novel compounds. EIPE structure serves as scaffolding for functional groups that may have antibacterial properties. Both gram-positive and gram-negative organisms are screened against EIPE derivatives using a standardized Kirby Bauer disk agar diffusion assay. These results showed that EIPE-1 has antibacterial properties against some pathogenic gram-positive organisms.
