Cross-linked poly(N-benzyl-4-vinylpyridinium halide) (designated insoluble BVP) was previously reported to capture bacterial cells alive by contact with them. The corresponding linear polymer poly(N-benzyl-4-vinylpyridinium salt) (designated soluble BVP) was found to exhibit antibacterial activity. This soluble pyridinium-type polymer showed strong antibacterial activity against gram-positive bacteria, whereas it was less active against gram-negative bacteria. The antibacterial activity of this cationic, polymeric disinfectant was considerably greater than that of the corresponding monomeric compound and was approximately equal to that of conventional disinfectants such as benzalkonium chloride and chlorohexidine.
交联聚(N-苄基-4-乙烯基卤化吡啶鎓)(称为不溶性BVP)此前有报道称可通过与细菌细胞接触来捕获活细菌细胞。发现相应的线性聚合物聚(N-苄基-4-乙烯基吡啶盐)(称为可溶性BVP)具有抗菌活性。这种可溶性吡啶鎓型聚合物对革兰氏阳性菌表现出很强的抗菌活性,而对革兰氏阴性菌的活性较弱。这种阳离子型聚合物消毒剂的抗菌活性大大高于相应的单体化合物,且与苯扎氯铵和氯己定等传统消毒剂大致相当。
