a. baumannii

Cyclo-L-Trp-L-Trp is a broad-spectrum antifungal. It also induces a high degree of acetylation of histones.

P1 is a broad-spectrum antimicrobial peptide effective against both Gram-positive and Gram-negative bacteria, including B. anthracis spores and Carbapenem-resistant strains of A. baumannii and K. pneumoniae [1].

Histatin 8, a salivary antimicrobial peptide derived from proteolytic fragments of histatin 3 and histatin 5, exhibits activity against A. baumannii strains, both colistin-susceptible and -resistant, at a concentration of 32 µg/ml. Additionally, it is effective against C. albicans and C. tropicalis, with minimum inhibitory concentrations (MICs) of 1 and 5 mg/ml, respectively.

SAAP 148, an antimicrobial peptide, effectively combats various multidrug-resistant bacteria in vitro and, in vivo, reduces skin colony-forming units (CFUs) in mouse models of A. baumannii or methicillin-resistant S. aureus (MRSA) infections at concentrations ranging from 0.125-2% w/w.
