Polymyxin B sulfate has a bactericidal action against almost all gram-negative bacilli except the Proteus group. Polymyxin B sulfate interacts with the lipopolysaccharide of the cytoplasmic outer membrane of Gram-negative bacteria, altering membrane permeability and causing cell death. It does not need to enter the cell.

暴露途径
眼神接触;非肠道给药(鞘内给药、肌肉注射、静脉滴注)。不从正常的消化道吸收。
Eye contact; parenteral (intrathecal, intramuscular injection, intravenous drip). Not absorbed from the normal alimentary tract.
Facial flushing, dizziness progressing to ataxia, drowsiness, peripheral paresthesias (circumoral and stocking glove), apnea due to concurrent use of curariform muscle relaxants, other neurotoxic drugs or inadvertent overdosage, and signs of meningeal irritation with intrathecal administration, e.g., fever, headache, stiff neck and increased cell count and protein cerebrospinal fluid. Other reactions occasionally reported: Drug fever, urticarial rash, pain (severe) at intramuscular injection sites, and thrombophlebitis at intravenous injection sites. (L1876)
Proguanil has been found to have rapid and effective killing activity against a variety of disease-causing micro-organisms. For example, when applied topically, proguanil is particularly effective against
Propionibacterium acnes
, a bacteria that causes acne;
Corynebacterium minutissimum
, a bacteria that causes erythrasma,
Gardnerella vaginalis
, a bacteria that causes vaginosis;
Trichomonas vaginalis
, a protozoan that causes trichomoniasis and
C. albicans
, a fungus (a form of yeast).

. The novel compounds have antibacterial properties against a diverse range of gram negative bacteria and reduced toxicity compared to polymyxins such as polymyxin B. Also provided are antibacterial pharmaceutical compositions containing the novel compounds and novel protected compounds, as well as methods for preparing the antibacterial compounds and protected compounds.
The present disclosure relates generally to the field of immunological-based diagnostic assays. Particularly, a method is contemplated herein for measuring cell-mediated immune response reactivity. The present disclosure further provides a method to reduce incidence of non-specific immune response reactivity in a cell-mediated immune response-based assay, comprising contacting a sample with a basic peptide structure capable of binding to lipopolysaccharides, such as polymyxin B or a sushi peptide.
本公开内容一般涉及基于免疫学的诊断检测领域。特别是,本文考虑了一种测量细胞介导的免疫应答反应性的方法。本公开进一步提供了一种在基于细胞介导的免疫反应测定中降低非特异性免疫反应反应性发生率的方法,包括将样品与能够与脂多糖结合的基本肽结构(如多粘菌素 B 或寿司肽)接触。
