Brilacidin tetrahydrochloride (PMX 30063 tetrahydrochloride) 是一种抗菌剂，对革兰氏阳性菌 Streptococcus pneumonia 和 Streptococcus viridans 的 MIC90 分别为 1 和 8 μg/mL，对革兰氏阴性菌 Haemophilus influenza 和 Pseudomonas aeruginosa 的 MIC90 分别为 8 和 4 μg/mL。Brilacidin tetrahydrochloride 是一种类似防御素的抗生素 (antibiotic)。

Brilacidin tetrahydrochloride (PMX 30063 tetrahydrochloride) is an anti-infective antimicrobial with MIC90s of 1 and 8 μg/mL for Gram-positive bacteria Streptococcus pneumonia and Streptococcus viridans, and MIC90 of 8 and 4 μg/mL for Gram-negative bacteria Haemophilus influenza and Pseudomonas aeruginosa. Brilacidin tetrahydrochloride is a defensin mimetic antibiotic compound.

Solid

Both Staphylococcus aureus (SA) and Staphylococcus epidermidis (SE) have the lowest minimum inhibitory concentrations among the bacterial groups. The MIC90s to Brilacidin for Streptococcus pneumonia (SP), Streptococcus viridians (SV), Moraxella (MS), Haemophilus influenza (HI), Pseudomonas aeruginosa (PA), and Serratia marcescens (SM) are 4, 32, 256, 32, 16, and 128-fold higher, respectively, than SA and SE. Brilacidin has Gram-positive in vitro activity; topical Brilacidin 0.5% is minimally irritating; and Brilacidin 0.5% was equally efficacious as Vancomycin (VAN) in a methicillin-resistant S. aureus (MRSA) keratitis model when the corneal epithelium is removed. Brilacidin acts primarily on the bacterial cell membrane by depolarization. Brilacidin is more potent for Gram-positive bacteria (except SV)

Brilacidin demonstrates dose-dependent ocular toxicity after 7 topical instillations (every 30?min for 3?h) in the NZW rabbit ocular toxicity model. Brilacidin 1% is determined to be Mildly Irritating (23.0), Brilacidin 0.5% (6.5), and Brilacidin 0.25% (4.0) are determined to be Minimally Irritating, while Brilacidin 0.1% (2.0) and TBS (1.0) are determined to be Practically Nonirritating and 0.01% Brilacidin (0.5) is determined to be Nonirritating based on their Maximum mean total scores (MMTS) values. has not independently confirmed the accuracy of these methods. They are for reference only.
