Use of VX853
Timcodar, also known as VX-853, is a novel multidrug resistance Inhibitor. Timcodar was under clinical trials to treat cancaners and other diseases. Timcodar potentiated the activity of ethidium bromide (EtBr), a model efflux substrate, against three clinically significant gram-positive pathogens: Staphylococcus aureus, Enterococcus faecalis, and Streptococcus pneumoniae. Similar to reserpine, VX-853 directly blocked EtBr efflux in S. aureus. Furthermore, VX-853 was effective in lowering the MICs of several clinically used antibiotics, including fluoroquinolones, suggesting that VX-853 are representatives of a new class of bacterial efflux inhibitors with the potential for use in combination therapy.
