中药光敏剂和声敏剂在抗菌领域的研究进展

    Research Progress of Photosensitizers and Sonosensitizers from Traditional Chinese Medicine in the Field of Antibacterial Therapy

    • 摘要: 细菌感染严重威胁全球公众健康。目前,抗生素疗法是细菌感染的主要治疗方式,但疗效差、复发率高、易引起正常菌群失调等问题依旧无法规避。且随着广谱抗生素在临床的滥用和误用,细菌耐药性逐年攀升,导致细菌感染,特别是多重耐药菌感染的治疗变得极为棘手。光动力疗法和声动力疗法主要利用特定波长的光照或低频超声波来激活光敏剂或声敏剂,使其产生活性氧分子,进而发挥抑菌与杀菌作用。作为一种新型抗菌手段,该疗法具有广谱抗菌活性,且不易诱发耐药性,对多种耐药菌均有效。其中,来源于中药活性成分的光敏剂和声敏剂因分子多样性良好、生物活性丰富、不良反应较少、价格低廉、提取工艺简单等优势,在光动力和声动力抗菌领域展现出广阔的应用前景。鉴于此,本文主要对中药光敏剂和声敏剂在抗菌领域的研究进展进行综述。

       

      Abstract: Bacterial infections pose a serious threat to global public health. Currently, antibiotic therapy is the primary treatment for bacterial infections, but issues such as poor efficacy, high recurrence rates, and the potential to disrupt normal flora remain unavoidable. Moreover, the misuse and overuse of broad-spectrum antibiotics in clinical settings have led to a yearly increase in bacterial resistance, making the treatment of bacterial infections, especially those caused by multidrug-resistant bacteria, particularly challenging. Photodynamic therapy and sonodynamic therapy primarily utilize light of specific wavelengths or low frequency ultrasound to activate photosensitizers or sonosensitizers, prompting the production of reactive oxygen species to inhibit and kill bacteria. As a novel antibacterial approach, photodynamic therapy and sonodynamic therapy have broad-spectrum antibacterial activity and are less likely to induce resistance, proving effective against a variety of drug-resistant bacteria. Photosensitizers and sonosensitizers derived from active components of traditional Chinese medicine have shown great molecular diversity, rich biological activity, low toxicity, and side effects, as well as the advantages of low cost and simple extraction processes, demonstrating a broad application prospects in the field of photodynamic and sonodynamic antibacterial therapy. Given this, this article mainly reviews the research progress of photosensitizers and sonosensitizers from traditional Chinese medicine in the antibacterial field.
