抗生素广泛使用,细菌对现有抗生素产生了多种耐药性,且近年开发的抗菌新药种类较少。阳离子抗菌肽(CAP)不易引起细菌耐药性,是研发中的一类有前途的抗菌药物。不同种类的CAP具有不同的生物学活性,很难单一解释其作用机制,要将其运用到药物领域,还有很多难题。其中一个研究方向 Antibiotics are widely used. The bacteria have produced many kinds of resistance to the existing antibiotics, and there are few antibacterial new drugs developed in recent years. Cationic antimicrobial peptides (CAP) is not easy to cause bacterial resistance, is a kind of promising antibacterial drugs in research and development. Different types of CAP have different biological activities, it is difficult to explain their mechanism of action alone, to be applied to the field of drugs, there are many problems. One of the research directions
