Cefetecol
Cefetecol (GR69153) is a semisynthetic β-lactam antibacterial agent and α-glucosidase inhibitor (yeast IC50 = 2.1 μM; Ki = 5.78 μM) that crosses the blood-brain barrier. Cefetecol reduces blood glucose levels in Streptozotocin-induced diabetic mice. Cefetecol decreases the mRNA expression of GSK-3, PPAR-γ, and UCP-3. Cefetecol induces bacterial cell filamentation and exhibits bactericidal activity against Gram-positive and Gram-negative bacteria. Cefetecol is used in the study of diabetes and bacterial infections.

Beschreibung
In Vivo
Cefetecol (0.10-0.95 mg/mouse; subcutaneous injection; single or three doses; 7-10 days) is effective against experimental intraperitoneal infection in mice, with ED50 values of 0.10 to 0.95 mg/mouse for single dosing and 0.02 to 0.31 mg/mouse for three doses[3].
Cefetecol (subcutaneous injection; twice) effectively inhibits the formation of experimental subcutaneous abscesses caused by S. aureus in mice[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:C57BL/6NKist (female, streptozotocin-induced diabetic model)[1]
-
Dosage:30 mg/kg/day
