1.Comparative mechanistic studies of brilacidin, daptomycin, and the antimicrobial peptide LL16.
Mensa B;Howell GL;Scott R;DeGrado WF Antimicrob Agents Chemother. 2014 Sep;58(9):5136-45. doi: 10.1128/AAC.02955-14. Epub 2014 Jun 16.
Brilacidin (PMX30063) has shown potent bactericidal activity against drug-resistant and -susceptible strains of multiple Gram-negative and Gram-positive pathogens. In this study, we demonstrate that brilacidin causes membrane depolarization in the Gram-positive bacterium Staphylococcus aureus, to an extent comparable to that caused by the lipopeptidic drug daptomycin. Transcriptional profiling of Staphylococcus aureus by deep sequencing shows that the global response to brilacidin treatment is well correlated to those of treatment with daptomycin and the cationic antimicrobial peptide LL37 and mostly indicates abrogation of cell wall and membrane functions. Furthermore, the upregulation of various chaperones and proteases by brilacidin and daptomycin indicates that cytoplasmic protein misfolding stress may be a contributor to the mechanism of action of these drugs. These stress responses were orchestrated mainly by three two-component systems, GraSR, VraSR, and NsaSR, which have been implicated in virulence and drug resistance against other clinically available antibiotics.
2.An Independent Evaluation of a Novel Peptide Mimetic, Brilacidin (PMX30063), for Ocular Anti-infective.
Kowalski RP;Romanowski EG;Yates KA;Mah FS J Ocul Pharmacol Ther. 2016 Jan-Feb;32(1):23-7. doi: 10.1089/jop.2015.0098. Epub 2015 Oct 26.
OBJECTIVE: ;Brilacidin (BRI), a novel defensin mimetic, was evaluated as an ocular anti-infective.;METHODS: ;In vitro: Potency based on MIC90s was compared for 50 Staphylococcus aureus (SA), 50 Staphylococcus epidermidis (SE), and 25 each of Streptococcus pneumonia (SP), Streptococcus viridans (SV), Moraxella (MS), Haemophilus influenzae (HI), Pseudomonas aeruginosa (PA), and Serratia marcescens (SM). In vivo: Using established methods, ocular toxicity was graded with Draize testing. For efficacy testing, both corneas of 24 rabbits were infected with methicillin-resistant S. aureus (MRSA), whereas the corneal epithelium was removed in the left eye. After 4 h, 21 topical drops over 5 h were administered to 4 groups: BRI 0.5%, vancomycin (VAN) 5%, saline, and no treatment. The eyes were clinically graded and the corneas were harvested for colony counts.;RESULTS: ;In vitro: Both SA and SE had the lowest minimum inhibitory concentrations among the bacterial groups. The MIC90s to BRI for SP, SV, MS, HI, PA, and SM were 4, 32, 256, 32, 16, and 128-fold higher, respectively, than SA and SE. In vivo: Draize testing determined BRI 0.5% to be minimally irritating. For abraded corneas, BRI was not statistically different from VAN for reducing MRSA.
