Histatin 5 (trifluoroacetate salt)

Histatin 5 is a salivary antimicrobial peptide. It is active against C. albicans (LC50 = 1.8 µM), as well as A. baumannii, P. aeruginosa, and E. cloacae (MICs = 38, 47, and 90 µM, respectively). Topical application of histatin 5 (20 µM) decreases fungal burden in a mouse model of C. albicans-induced vulvovaginal candidiasis.Formal Name: L-alpha-aspartyl-L-seryl-L-histidyl-L-alanyl-L-lysyl-L-arginyl-L-histidyl-L-histidylglycyl-L-tyrosyl-L-lysyl-L-arginyl-L-lysyl-L-phenylalanyl-L-histidyl-L-alpha-glutamyl-L-lysyl-L-histidyl-L-histidyl-L-seryl-L-histidyl-L-arginylglycyl-L-tyrosine, trifluoroacetate salt.
