对支原体感染的获得性耐药性正迅速成为一个主要的医学问题。寄生性真菌感染产生治疗挑战,特别是在患有AIDS、癌症的高风险免疫功能低下患者和那些经历移植的患者中。在过去的20年里,由于侵袭性真菌病导致的更高的死亡率和/或发病率一直在增加,并且鉴于对常用抗生素的耐药性不断增加,需要新的抗真菌药物和方法。目前,在植物和动物王国中普遍存在的抗真菌肽引起了相当大的兴趣。这些小的阳离子肽可能具有特定的靶点,或者在其作用机制中可能是多功能的。在蛋白质工程和固相合成的最新进展的基础上,所选肽作为具有可接受毒性的有效抗真菌药物的效用和潜力正在实现。本文将讨论肽治疗机会性真菌感染的最新进展。
Acquired drug resistance to mycotic infections is rapidly emerging as a major medical problem. Opportunistic fungal infections create therapeutic challenges, particularly in high risk immunocompromised patients with AIDS, cancer, and those undergoing transplantation. Higher mortality and/or morbidity rates due to invasive mycosis have been increasing over the last 20 years, and in light of growing resistance to commonly used antibiotics, novel antifungal drugs and approaches are required. Currently there is considerable interest in antifungal peptides that are ubiquitous in plant and animal kingdoms. These small cationic peptides may have specific targets or may be multifunctional in their mechanism of action. On the basis of recent advances in protein engineering and solid phase syntheses, the utility and potential of selected peptides as efficient antifungal drugs with acceptable toxicity profiles are being realized. This review will discuss recent advances in peptide therapy for opportunistic fungal infections.
