The present invention includes novel compounds based on the tomatidine skeleton as well as composition comprising these compounds alone and in combination with known compounds, which exhibit antimicrobial activity against extracellular or intracellular electron transport-deficient microbes and/or increase the antimicrobial activity of aminoglycoside antibiotics against their targets, and which are useful as antibacterial agents for treatment or prophylaxis of monomicrobiotic or polymicrobic bacterial infections or for the reduction of antibiotic resistance development in animals or in humans, or for use as antiseptics or agents for sterilization or disinfection.

The present invention provides bacterial ATP synthase inhibitors such as a compound of formula (I): (Formula (I)) (A) in combination with an aminoglycoside antibiotic for preventing or treating a bacterial infection in a subject; or (B) (a) for preventing or treating an infection caused by an electron transport-deficient bacteria in a subject; or (b) for the disinfection, sterilization and/or antisepsis of an object contaminated with an electron transport-deficient bacteria. There are provided compositions and kits using such compounds and inhibitors.

potent against prototypical S. aureus and E. coli strains (MIC 8 and 32 µg/mL, respectively), whereas TM-02 is more potent against SCV (MIC 0.5 µg/mL) and hyperpermeable E. coli strains (MIC 1 µg/mL). The differences in their modes of action were investigated. We used membrane vesicles to confirm the inhibition of the bacterial ATP synthase, the documented target of TO, and measured effects on bacterial
Unraveling the structure–activity relationship of tomatidine, a steroid alkaloid with unique antibiotic properties against persistent forms of Staphylococcus aureus
that tomatidine, a steroid alkaloid isolated from tomato plants, possesses anti-virulence activity against normal strains of S. aureus as well as the ability to potentiate the effect of aminoglycoside antibiotics. In addition, tomatidine has shown antibiotic activity against small-colony variants of S. aureus. We herein report the first study of the structure–activity relationship of tomatidine against
