天然产物(NPs)是新型化合物和新药的丰富来源。在本研究中,我们使用化学空间导航工具ChemGPS-NP来评估化学空间占用的NP和生物活性药物化学化合物从数据库WOMBAT。这两组在化学空间的覆盖范围上有显著的不同,并且发现有形的铅样纳米颗粒覆盖了WOMBAT中缺乏代表性的化学空间区域。进行基于性质的相似性计算以鉴定批准药物的NP邻居。通过这种方法揭示的几个NP被证实表现出与其药物邻居相同的活性。在寻找具有独特性质的新线索时,从NP起始点鉴定线索可能证明是药物发现的有用策略。
Natural products (NPs) are a rich source of novel compound classes and new drugs. In the present study we have used the chemical space navigation tool ChemGPS-NP to evaluate the chemical space occupancy by NPs and bioactive medicinal chemistry compounds from the database WOMBAT. The two sets differ notable in coverage of chemical space, and tangible lead-like NPs were found to cover regions of chemical space that lack representation in WOMBAT. Property based similarity calculations were performed to identify NP neighbours of approved drugs. Several of the NPs revealed by this method, were confirmed to exhibit the same activity as their drug neighbours. The identification of leads from a NP starting point may prove a useful strategy for drug discovery, in the search for novel leads with unique properties.
