Disifin has emerged as a unique and very effective agent used in disinfection of wounds, disinfection of surfaces, materials and water, and other substances contaminated with almost every type of pathogenic microorganism ranging from viruses, bacteria, fungi and yeast, and, very possibly, protozoan parasites, as well. The major active component of Disifin is tosylchloramide sodium (chloramine T). However, the mechanism by which Disifin suppresses the activities of pathogenic microbial agents remains enigmatic. The molecular mechanisms, and the receptors and the signal transducing pathways responsible for the biological effects of Disifin are largely unknown. Despite considerable advances, enormous investigative efforts and large resources invested in the research on infectious diseases, microbial infection still remains a public health problem in many parts of the world. The exact nature of the pathogenic agents responsible for many infectious diseases, and the nature of the receptors mediating the associated inflammatory events are incompletely understood. Recent advances in understanding the molecular basis for mammalian host immune responses to microbial invasion suggest that the first line of defense against microbes is the recognition of pathogen-associated molecular patterns (PAMPs) by a family of transmembrane pattern-recognizing and signal transducing receptor proteins called Toll-like receptors (TLRs). The TLR family plays an instructive role in innate immune responses against microbial pathogens, as well as the subsequent induction of adaptive immune responses. TLRs mediate recognition and inflammatory responses to a wide range of microbial products and are crucial for effective host defense by eradication of the invading pathogens. Now, recent updates demonstrated the ability of Disifin-derived products, Disifin-Animal and Disifin-Pressant to effectively suppress the progression and activities of Chikungunya fever and that of avian influenza A virus [A/cardialis/Germany/72, H7N1: the agent of a highly pathogenic avian influenza (HPAI)] infection, respectively. Overall, the above findings led me to suggest that Disifin and TLRs may mechanistically overlap in the processes of executing their functions against pathogenic microbial organisms. Thus, elucidating and better understanding of the molecular underpinnings responsible for the biochemical effects of Disifin-products, and the nature and mode of the interaction(s) of Disifin with TLRs in the process of exerting their biological effects may open a novel dimension in the research of infectious diseases, which may provide novel therapeutic targets for the prevention and treatment of a wide range of infectious diseases.
迪西芬已成为一种独特且非常有效的药剂,可用于伤口消毒、表面消毒、材料和水消毒,以及对几乎所有类型致病微生物(包括病毒、细菌、真菌和酵母,甚至很可能还有原生动物寄生虫)污染的其他物质进行消毒。迪西芬的主要活性成分是对甲苯磺酰氯胺钠(氯胺T)。然而,迪西芬抑制致病微生物活性的机制仍然不明。迪西芬产生生物学效应的分子机制、受体及信号转导途径在很大程度上尚不清楚。尽管在传染病研究方面取得了显著进展、投入了大量的研究精力和资源,但微生物感染在世界许多地区仍然是一个公共卫生问题。许多传染病致病因子的确切性质以及介导相关炎症事件的受体性质尚未完全了解。在理解哺乳动物宿主对微生物入侵的免疫反应分子基础方面的最新进展表明,针对微生物的第一道防线是一类称为Toll样受体(TLR)的跨膜模式识别和信号转导受体蛋白识别病原体相关分子模式(PAMP)。TLR家族在针对微生物病原体的固有免疫反应以及随后适应性免疫反应的诱导中发挥指导作用。TLR介导对多种微生物产物的识别和炎症反应,对于通过根除入侵病原体实现有效的宿主防御至关重要。现在,最近的更新表明,迪西芬衍生产品迪西芬-动物型和迪西芬-压力型分别能够有效抑制基孔肯雅热的进展和活动以及甲型禽流感病毒[A/心型/德国/72,H7N1:高致病性禽流感(HPAI)病原体]感染。总体而言,上述发现使我认为迪西芬和TLR在针对致病微生物执行其功能的过程中可能在机制上存在重叠。因此,阐明并更好地理解迪西芬产品生化效应的分子基础,以及迪西芬在发挥其生物学效应过程中与TLR相互作用的性质和模式,可能会为传染病研究开辟一个新的维度,这可能为预防和治疗多种传染病提供新的治疗靶点。
