Debio 1453
Debio 1453 is a bactericidal FabI inhibitor potent against N. gonorrhoeae (IC50 = 0.6 nM), including drug-resistant strains. Debio 1453 demonstrates a low propensity for resistance selection and is effective in eradicating both planktonic and intracellular bacteria through a mechanism of concurrently inhibiting FabI and engaging the non-mutable NADH cofactor. Debio 1453 clears antibiotic-resistant N. gonorrhoeae infection in a murine vaginal model. Debio 1453 can be used for gonorrhoea research.

Biological Activity
Debio 1453 shows activity against 2024 World Health Organisation N. gonorrhoeae reference strains that include strains resistant to Ceftriaxone (HY-B0712), Azithromycin (HY-17506), Spectinomycin (HY-B0438), Tetracycline (HY-A0107) and Ciprofloxacin (HY-B0356), with MIC range 0.03-0.125 μg/mL[1].
Debio 1453 exhibits potent in vitro activity (MIC50/MIC90 = 0.06 μg/mL) against 100 contemporary clinical N. gonorrhoeae isolates, with MICs ranging from 0.008 to 0.125 μg/mL[1].
Debio 1453 (0-16x MIC, 0-24 h) displays rapid bactericidal killing against both antibiotic-susceptible and extensively drug-resistant (XDR) N. gonorrhoeae in a time-dependent manner[1].
Debio 1453 (0-8x MIC, 0-24 h) is effective against both internalised antibiotic-susceptible (ATCC 49226) and XDR N. gonorrhoeae (WHO X), eradicating the bacteria to the limit of detection within 24 h for each isolate tested (≥3.1 log10 CFU/mL and ≥2.8 log10 CFU/mL reductions, respectively)[1].
Debio 1453 (4x-16x MIC) exhibits a low propensity for selecting mutants with reduced susceptibility in N. gonorrhoeae in vitro, thus validating FabI as its target[1].
Debio 1453 (0.3-30 μM, 24 h) exhibits no cytotoxicity or negative impact on cell viability in HepG2 cells, and no clastogenic or aneugenic activity in lymphocytes irrespective of the presence or absence of a rat liver metabolic activation system[1].
