Hodoodo CAT#: H317398

CAS#: 87239-81-4 (Proxetil)

Description: Cefpodoxime Proxetil is an antibacterial with a broad spectrum activity. It is an oral, third generation cephalosporin, ester prodrug of the active free acid metabolite Cefpodoxime. It is active against most Gram-positive and Gram-negative organisms. It is commonly used to treat acute otitis media, pharyngitis, sinusitis, and gonorrhea. It also finds use as oral continuation therapy when intravenous cephalosporins (such as ceftriaxone) are no longer necessary for continued treatment. Currently, it is only marketed as generic preparations in the USA.

More Info:

Biological target: Cefpodoxime Proxetil binds to penicillin binding proteins (PBPs), which inhibits peptidoglycan synthesis, finally results in interfering bacterial cell wall biosynthesis.
In vitro activity: Cefpodoxime proxetil (5) was identified as the hit compound, and it was found for the first time that 5 might have neuroprotective activity as a NR2B-NMDAR antagonist. This result prompted further study, the ligand-receptor interactions modeled by molecular docking studies showed that the compound could perfectly merge both the pharmacophore characteristics of ifenprodil and EVT-101 at the binding cavity between the ATDs of GluN1 and GluN2B. The accuracy of molecular docking results and binding stability of ligand-receptor complexes were validated through 100 ns molecular dynamics simulation and binding free energy calculation. Afterwards, MTT assay (49.8%±0.1%, 5 μM) on NMDA injured SH-SY5Y cells and evidence of the effect on attenuating Ca2+ influx induced by NMDA were applied to validate the computational results, further investigation showed that 5 could suppress the NR2B upregulation induced by NMDA.
