Kalata B1 vs Tyrocidine

Kalata B1 vs Tyrocidine — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Kalata B1
Antimicrobial Peptide

Kalata B1 is the prototype cyclotide - a cyclic peptide with a head-to-tail backbone cyclization and three disulfide bonds forming a cystine knot topology. Isolated from the plant Oldenlandia affinis, which is traditionally used in Africa to accelerate childbirth (uterotonic use)...

Tyrocidine
Antimicrobial Peptide

Tyrocidine A is a cyclic decapeptide component of tyrothricin, one of the first antibiotic mixtures produced commercially. Isolated from Bacillus brevis soil bacteria, tyrocidines are non-ribosomally synthesized peptides that disrupt bacterial membranes through a carpet mechanism...
