Alamethicin vs Teixobactin

Alamethicin vs Teixobactin — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Alamethicin
Antimicrobial Peptide

Alamethicin is a 20-residue peptaibol (peptide with a high proportion of alpha-aminoisobutyric acid, Aib) from the fungus Trichoderma viride. It is the prototypical voltage-gated peptide ion channel, forming multi-state conductance channels in lipid bilayers whose opening probabi...

Teixobactin
Antimicrobial Peptide

Teixobactin was reported in Nature in 2015 as the first new antibiotic class discovered in 30 years, isolated from uncultured soil bacteria Eleftheria terrae using the iChip (isolation chip) technology that allows cultivation of previously unculturable organisms. Teixobactin bind...
