Investigations on diverse aspects of fluoro-organic compounds have rapidly increased during the past decades. Because natural sources of fluoro-organic compounds are extremely rare, the industrial synthesis of fluorinated organic compounds and production of fluorinated natural product derivatives have greatly expanded in recent years because of their increasing importance in the agrochemical and pharmaceutical industries. Due to structural complexity or instability, synthetic modification is often not possible, and various biofluorination strategies have been developed in recent years for applications in the anti-cancer, anti-viral and anti-infection fields. Despite the industrial importance of fluorinated compounds, there have been serious concerns worldwide over the levels and synthetic routes of certain fluorinated organic compounds, in particular perfluorinated chemicals (PFCs). PFCs are emerging and recalcitrant pollutants which are widely distributed in the environment and have been detected in humans and wildlife globally. PFCs have been demonstrated to be potentially carcinogenic, adversely affect the neuroendocrine and immune systems, and produce neurotoxicity, heptatotoxicity and endocrine disrupting effects in vertebrate animals. Here, we provide an overview of recent advances in our understanding of the biology of various fluoro-organic compounds and perspectives for new enzymes and metabolic pathways for bioremediation of these chemicals.
在过去几十年里,对氟有机化合物各个方面的研究迅速增加。由于氟有机化合物的天然来源极为稀少,近年来,氟化有机化合物的工业合成以及氟化天然产物衍生物的生产因在农用化学品和制药行业的重要性不断增加而得到极大扩展。由于结构复杂或不稳定,合成修饰往往无法实现,近年来已开发出各种生物氟化策略,用于抗癌、抗病毒和抗感染领域。尽管氟化合物具有工业重要性,但全球范围内对某些氟有机化合物的含量和合成途径,特别是全氟化学品(PFCs),存在严重担忧。PFCs是新出现的难降解污染物,广泛分布于环境中,在全球范围内的人类和野生动物体内均有检测到。已证明PFCs具有潜在致癌性,对神经内分泌和免疫系统产生不利影响,并在脊椎动物中产生神经毒性、肝毒性和内分泌干扰作用。在此,我们概述了近期在理解各种氟有机化合物生物学方面取得的进展,以及针对这些化学品生物修复的新酶和代谢途径的前景。
