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.

Description

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[1].

In Vitro

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].

In Vivo

Debio 1453 (10-160 mg/kg (dosed as Debio 1453 P), p.o., twice daily for 2 days) shows potent efficacy in murine models of both N. gonorrhoeae vaginal infection and S. aureus thigh infection[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Ovariectomized BALB/c female mice (5-6 weeks) infected intravaginally with N. gonorrhoeae strains[1]
Dosage: 10, 20, 30, 40, 80, and 160 mg/kg (dosed as Debio 1453 P)
Administration: p.o., twice daily for 2 days
Result: Demonstrated efficacy against all tested strains, producing clear dose-response relationships.
Achieved ~3 log10 CFU/mL reductions as compared to the start of treatment (0 h) and eradicated N. gonorrhoeae to the limit of detection by 48 h at multiple dose levels.
Animal Model: Neutropenic female ICR mice infected intravaginally with S. aureus[1]
Dosage: 10, 20, 30, 40, and 80 mg/kg (dosed as Debio 1453 P)
Administration: p.o., twice daily for 2 days
Result: Achieved >1 log10 CFU/mL reductions in thighs at 24 h and >2 log10 CFU reductions at 48 h, displaying efficacy comparable to a supratherapeutic dose of Linezolid (HY-10394).

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
