目前,由于抗菌素的大量使用,耐药菌株和多重耐药菌株不断增加,使抗感染治疗成为一个棘手的难题。抗菌肽(anti-bacterial peptides)正是在这种形势下出现的一类具有发展潜力的新型抗菌药物。抗菌肽广泛存在于昆虫、植物、动物及人体内,是宿主产生的一类抵抗病原体感染的小分子多 At present, the anti-infective treatment has become a thorny problem due to the extensive use of antibiotics, the increasing number of drug-resistant strains and multi-drug resistant strains. Antimicrobial peptides (anti-bacterial peptides) It is in this situation there is a new class of potential antibacterial drugs. Antimicrobial peptides widely exist in insects, plants, animals and human body, is a kind of host to produce a variety of small molecules resistant to pathogen infection
