摘要
抗菌肽是一类具有抗菌、抗病毒、抗肿瘤等生物活性的小分子多肽,与传统抗生素相比,不易产生耐药性;但因其毒性强、稳定性差、合成成本高等原因,抗菌肽还不能广泛应用于临床。为此,药物学家们对其进行了结构改造,获得了高活性、低毒性的抗菌肽。该文综述了抗菌肽分子设计的研究进展及发展方向。
Antimicrobial peptides （ AMPs） are a kind of micromolecular peptides with antibacterial , antivirus and anti-tumor activities.Unlike conventional antibiotics , acquisition of resistance by a sensitive microbial strain against AMPs is surprisingly improbable .AMPs are not widely used clinically due to their toxicity , susceptibility to proteolysis and high manufacturing cost .Researchers have obtained some AMPs with high activity and low toxicity by structure modifications . The molecular design of AMPs as well as their development in the future are reviewed .
