Product Description
Mechanism of Action
Cephalexin monohydrate is a first‑generation oral cephalosporin that inhibits bacterial cell‑wall synthesis through high‑affinity binding to PBPs, blocking transpeptidation of peptidoglycan chains. The monohydrate form ensures stability and predictable oral absorption. Strong activity is seen against gram‑positive cocci and certain gram‑negative bacilli.
Benefits and Advantages
Used in gram‑positive susceptibility profiling, β‑lactam SAR research, staphylococcal cell‑wall studies, oral PK modelling, biofilm‑growth inhibition assays and early‑generation cephalosporin mechanistic comparisons.
Side Effects and Risks
Risks include hypersensitivity, GI irritation, candidal overgrowth, rare renal inflammation and potential cross‑reactivity in penicillin‑allergic subjects. Handle under β‑lactam containment standards.
