MedKoo product information:




Description of Timcodar: 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.
