Literature-reported activity
| Endpoint | Reported result | Experimental context | Source location |
|---|---|---|---|
| TEM-116 degradation DC50 | 5.8 ± 0.14 µM | Purified TEM-116 and DegP, 6 h; SDS-PAGE quantification; mean ± SEM, n=3 | Main Fig. 2D/E and p. 4 |
| Antibiotic-adjuvant activity | Improved bacterial growth inhibition versus tazobactam at 1 mg/mL piperacillin; poorer performance at lower piperacillin concentrations | E. coli harbouring pK18-TEM-1; kinetic growth assay; piperacillin 0.1, 0.33 or 1 mg/mL | Main Fig. 3A–C, pp. 5–6; SI Table S1 |
Evidence limits
- Biochemical degradation and bacterial growth inhibition are different endpoints.
- At 100 µM for 7 h without piperacillin, OXF-232 did not show detectable TEM-1 degradation in E. coli; enhanced cellular degradation must not be assumed for this series.
- At lower piperacillin concentrations (0.1 and 0.33 mg/mL), tazobactam performed better; at 1 mg/mL piperacillin, the degrader series showed improved growth inhibition.
- The term “in vivo” in the bacterial assays refers to living bacteria, not animal infection efficacy.
- No DC stock, purity, lead time or clinical efficacy is established by the literature.
These values are reported in the cited research and depend on the experimental conditions. DC Chemicals supplies research compounds; literature results are not guaranteed product performance.
