Thanatin TFA
Based on 1 Customer Validation
Thanatin TFA is an inducible cationic antimicrobial peptide. Thanatin TFA s a pathogen-inducible single-disulfide-bond-containing β-hairpin AMP. Thanatin TFA displays broad-spectrum activity against both Gram-negative and Gram-positive bacteria as well as against various species of fungi with MICs of 0.3-40 µM, 0.6-40 µM and 0.6-20 µM, respectively. Thanatin TFA has the property of competitive replacement of divalent cations from bacterial outer membrane (OM), leading to OM disruption.

Biological Activity
Thanatin TFA is strongly cationic (pI of 10.48) and contains a distinct short eight-residue basic loop created through a disulfide bond formation between residues Cys11 and Cys18 at the C-terminus. [1].
Thanatin TFA exhibits potent inhibitory effect on the growth of all New Delhi metallo-β-lactamase-1 (NDM-1)-producing E. coli and K. pneumoniae strains at 0.4-3.2 μM of the minimum inhibitory concentration (MIC) values[2].

Animal Model:Male BALB/c mice aged 8-10 weeks and weighing 18-22 g with CFU E. coli XJ141026
-
Dosage:1, 3, 6 mg/kg
-
Administration:Intraperitoneally injected; at 1 and 6 h
-
Result:1, 3, and 6 mg/kg markedly increased the survival rate from 0 to 30%, 70%, and 100%, respectively.
Showed that the bacterial titers decreased with increasing drug dose.
Rescued the pathological damages (large amounts of inflammatory cell infiltration, alveolar fusion, congestion in the spleen red pulp area, hepatic sinusoidal dilation and congestion) in a dose-dependent manner.
