catheters

Taurolidine 是一种广谱抗菌剂，用于预防中心静脉导管相关感染。它具有抗真菌和抗肿瘤作用。

CAP 3 is a cholic acid-peptide conjugate (CAP) with antibacterial activity. It is active against the Gram-negative bacteria E. coli, K. pneumoniae, and A. baumanii (MIC99s = 8, 16, and 16 μM, respectively). CAP 3 increases the fluidity of model Gram-negative bacterial membranes and binds to LPS in vitro. It reduces the biomass and number of colony-forming units in E. coli biofilms in a concentration-dependent manner. CAP 3 inhibits E. coli biofilm formation on catheters implanted in mice infected with E. coli at the incision site when applied as a coating on the catheters. CAP 3 (40 mg/kg) also reduces bacterial load in E. coli-infected wounds in mice. It is cytotoxic to A459 cells (IC50 = 56.4 μM) and has hemolytic activity against human red blood cells with a 50% lysis (HC50) value of 48 μM.

AETA (2-Acryloxyethyltrimethylammonium chloride) 可用于合成亲水聚合物和水凝胶。水凝胶常见于膜、导管、隐形眼镜以及活性分子输送系统。
