天然产物是大自然通过进化探索生物相关化学空间的结果,也是化学生物学和药物化学的生物活性小分子的宝贵来源。基于天然产物结构发现新的生物活性化合物类别的新概念可能使探索更广泛的生物相关化学空间成为可能。伪天然产物概念通过基于片段的化合物开发将天然产物结构的相关性与化学空间的有效探索相结合,以前所未有的安排通过天然产物片段的从头组合来激发新的生物活性化学物质的发现。新型支架保留了天然产物的生物相关性,但不能通过已知的生物合成途径获得,这可能导致可能具有意想不到或前所未有的生物活性的新化学型。在这里,我们涵盖了伪天然产品设计和开发的工作流程,突出最近的例子,并讨论了化学信息学分析,其中发现相当一部分生物活性合成化合物是伪天然产品。我们将这一概念与自然进化进行比较,并将伪天然产物作为人造等价物进行讨论,即天然产物结构的化学进化。
Natural products are the result of Nature’s exploration of biologically relevant chemical space through evolution and an invaluable source of bioactive small molecules for chemical biology and medicinal chemistry. Novel concepts for the discovery of new bioactive compound classes based on natural product structure may enable exploration of wider biologically relevant chemical space. The pseudo-natural product concept merges the relevance of natural product structure with efficient exploration of chemical space by means of fragment-based compound development to inspire the discovery of new bioactive chemical matter through de novo combination of natural product fragments in unprecedented arrangements. The novel scaffolds retain the biological relevance of natural products but are not obtainable through known biosynthetic pathways which can lead to new chemotypes that may have unexpected or unprecedented bioactivities. Herein, we cover the workflow of pseudo-natural product design and development, highlight recent examples, and discuss a cheminformatic analysis in which a significant portion of biologically active synthetic compounds were found to be pseudo-natural products. We compare the concept to natural evolution and discuss pseudo-natural products as the human-made equivalent, i.e. the chemical evolution of natural product structure.
