Brilacidin tetrahydrochloride (PMX-30063; PMX 30063) is a novel and potent arylamide foldamer that can mimic the amphiphilic properties of antimicrobial peptides. Asa broad-spectrum antibiotic,Brilacidin shows a broad-spectrum antibiotic activity against Gram+ and Gram- bacteria.Brilacidin has low cytotoxicity against mammalian cells selectively targeting bacteria, directly and rapidly disrupting their membranes, resulting in the bacteria's death. Due to this unique mechanism of action (mimicking the host's natural immune response, proven to be successful in fighting off infections over millions of years of evolution), bacterial antibiotic resistance is less likely to develop.
| ln Vitro |
Among the bacterial species, Staphylococcus aureus (SA) and Staphylococcus epidermidis (SE) have the lowest minimum inhibitory concentrations. Brilacidin's MIC90s for Serratia marcescens (SM), Moraxella (MS), Haemophilus influenza (HI), Pseudomonas aeruginosa (PA), Streptococcus pneumonia (SP), and Streptococcus viridians (SV) are 128-fold higher than those of SA and SE, respectively, at 4, 32, 256, 32, 16, and 16. In vitro, brilacidin possesses Gram-positive activity. Topical application of brilacidin 0.5% causes minimal irritation. When the corneal epithelium is removed from a methicillin-resistant S. aureus (MRSA) keratitis model, brilacidin 0.5% proved to be just as effective as vancomycin (VAN). Brilacidin mainly depolarizes the bacterial cell membrane in order to affect it. Compared to Gram-negative bacteria, brinalacidin is more effective against Gram-positive bacteria (apart from SV)[2].

| ln Vivo |
In the NZW rabbit ocular toxicity model, brinalacidin exhibits dose-dependent ocular toxicity following seven topical instillations (every 30 minutes for three hours). Based on their Maximum mean total scores (MMTS) values, Brilacidin 1% is found to be Mildly Irritating (23.0), Brilacidin 0.5% (6.5), and Brilacidin 0.25% (4.0) to be Minimally Irritating, while Brilacidin 0.1% (2.0), TBS (1.0), and 0.01% Brilacidin (0.5) are found to be Practically Nonirritating and Nonirritating, respectively[2].

Solubility in Formulation 1: ≥ 6.25 mg/mL (5.77 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 62.5 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 6.25 mg/mL (5.77 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 62.5 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
