Cefotetan
Based on 1 Customer Validation
Cefotetan is a binding agent that targets human Raf1 kinase inhibitor protein (hRKIP). Cefotetan binds to hRKIP, reduces the binding space between hRKIP and Raf1 kinase, relieves hRKIP's inhibition of the Ras/Raf1/MEK/ERK signaling pathway, and enhances ERK phosphorylation. Cefotetan can be used to study diseases associated with dysregulated Ras/Raf1/MEK/ERK signaling pathways. Cefotetan is also a broad-spectrum antibacterial agent that disrupts cell wall synthesis by binding to bacterial penicillin-binding proteins (PBPs). It is used to study bacterial infections such as bone, skin, urinary tract, and lower respiratory tract.

Cefotetan (20-80 μM; 30 min) significantly increases HEK293T and HeLa cells ERK phosphorylation levels, and this effect is more pronounced in cells overexpressing hRKIP[1].
Cefotetan is active against both Gram-positive bacteria (such as Staphylococci and Streptococci) and Gram-negative bacteria (such as Enterobacter and Haemophilus influenzae), and is highly stable against plasmid- and chromosome-mediated β-lactamases. 0.5 mg/L Cefotetan inhibits 75% of Enterobacter, 4 mg/L Cefotetan inhibits 90% of Enterobacter, and the MIC of Cefotetan against Neisseria gonorrhoeae is 0.06-2 mg/L[2].

-
Concentration:0 μM, 20 μM, 40 μM, 80 μM
-
Incubation Time:30 min
-
Result:Enhanced the phosphorylation level of ERK dose-dependently.
In hRKIP-transferred HEK293T cells, increased the phosphorylation level of ERK by approximately 300% compared with the control at 80 μM; in hRKIP-transferred HeLa cells, increased the phosphorylation level of ERK by approximately 250% under the same concentration.
