| Targets |
D13-9001 targets AcrB, the inner membrane component of the AcrAB-TolC efflux pump in Escherichia coli, and MexB, the corresponding component in Pseudomonas aeruginosa. These efflux pumps are major contributors to multidrug resistance in Gram-negative bacteria. By inhibiting AcrB and MexB, D13-9001 prevents the active extrusion of antibiotics from bacterial cells.
|
|---|---|
| ln Vitro |
D13-9001 has good safety and great solubility [3].
In vitro, D13-9001 binds to AcrB with a Kd of 1.15 μM in E. coli and to MexB with a Kd of 3.57 μM in P. aeruginosa. It exhibits antibiotic activity by blocking efflux pump function. The compound's inhibitory mechanism has been studied through molecular dynamics simulations to understand its binding interactions with these efflux pumps. |
| ln Vivo |
Rats with lethal pneumonia at the end of day seven respond better to treatment with D13-9001 (1.25–20 mg/kg; intravenous infusion; 2 hours) than to AZT alone [3].
In vivo activity data for D13-9001 are limited in the published literature. As an efflux pump inhibitor, it has potential applications in restoring antibiotic efficacy against multidrug-resistant bacterial infections. Further in vivo studies are needed to evaluate its efficacy in animal models of infection and to characterize its pharmacokinetic and pharmacodynamic properties. |
| Enzyme Assay |
In vitro enzyme/receptor binding assays for D13-9001 are performed using purified AcrB or MexB proteins. Binding affinity is measured using surface plasmon resonance (SPR) or isothermal titration calorimetry (ITC) to determine Kd values. Alternatively, efflux pump inhibition is assessed by measuring the accumulation of fluorescent substrates or radiolabeled antibiotics in bacterial cells in the presence of the compound.
|
| Cell Assay |
In vitro cellular assays for D13-9001 are performed using bacterial strains expressing AcrB or MexB efflux pumps. Bacteria are treated with the compound in the presence of a fluorescent efflux substrate or antibiotic, and the intracellular accumulation of the substrate is measured fluorometrically or by radiolabel counting. The reduction in efflux activity is quantified and compared to untreated controls.

| Animal Protocol |
Animal/Disease Models: SD rat (Pseudomonas aeruginosa PAM1020 lung infection) [3]
Doses: 1.25 mg/kg, 5 mg/kg, 20 mg/kg Route of Administration: intravenous (iv) (iv)infusion; 2 hour Experimental Results: 1.25, The combination of 5 and 20 mg/kg of D13-9001 with 1000 mg/kg of AZT improved survival at the end of day seven, whereas no significant effect was observed with treatment with AZT alone. In vivo animal experimental protocols for D13-9001 are not extensively documented. As a potential antibiotic adjuvant, in vivo studies would typically involve administration to mouse models of bacterial infection. The compound would be administered alone or in combination with an antibiotic, and efficacy would be assessed by measuring bacterial load, survival rates, and infection resolution. |
| ADME/Pharmacokinetics |
