Biological Activity

Ceftezole is a semi-synthetic first-generation cephalosporin antibiotic that possesses broad-spectrum antibacterial activity against various bacterial pathogens. It acts by binding to bacterial penicillin-binding proteins, thereby blocking transpeptidase-mediated peptidoglycan cross-linking required for cell wall assembly. Inhibition of this cell wall synthesis pathway weakens bacterial structural integrity, causing cell lysis and bacterial death in Gram-positive and Gram-negative organisms. [1]

Solubility

Batch:
All in vitro solubility values are batch-tested experimental data (non-literature values).
Solvent Solubility & Note
DMSO 88 mg/mL (199.78 mM)
(Moisture-contaminated DMSO may reduce solubility. Use fresh, anhydrous DMSO. The recommended stock concentration is 10 mM in DMSO.)
FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
