A screening was carried out on a small-molecule library to find inhibitors that prevent and eliminate Salmonella biofilms across various temperatures, while avoiding effects on bacterial growth to reduce resistance development.
Out of 20,014 compounds screened, 140 were identified as potential inhibitors, leading to further testing of their effectiveness at temperatures of 16, 25, 30, and 37 °C.
One notable compound, 7-methoxy-4-[4-(3-phenyl-2-propen-1-yl)-1-piperazinyl]-5H-pyrimido[5,4-b]indole, showed promise in preventing biofilm formation, with an analogue, 8-fluoro-4-[4
