TimTec NPL, Natural Product Library, is composed of 800 pure natural compounds as lead identifying material. Natural molecules tend to be multi-active across targets being inherently bio-available. The value of the library is in broad diversity representation of selected natural material available in screen-ready format. Compounds are primarily sourced from plants with the remaining samples from bacteria, fungus, and animal sources. Common natural sources and reference information is available for the majority of the samples.
Diversity by nature Purity by science Value by design
NPL is sold as a complete collection or by plate or by individual compounds; available in solid form or in DMSO solution at pre-plated or at custom concentration.
Rediscovering Natural products Article identifies the causes for the sustained interest in natural compounds:
TimTec Natural Product Library was screened to identify compounds that significantly reduce infectivity without cytotoxicity. NPL collection featured 280 compounds at the time of the moderate-throughput screening. MTS assay is adaptable to different virus systems. Out of 280 compounds, 15 molecules showed antiviral activity and were identified as promising models for immunomodulatory agents. Download available compounds that reduce rotavirus infectivity without cytotoxicity.
"We recently published our paper on the AhR and utilized your NPL library as part of a physical and virtual screen.Thanks for all your help, and if any of your scientists need any help understanding what we did, feel free to contact me again." - Dan Koch

TimTec Nature-Informed Libraries in Publications
NPL is one of TimTec nature-inspired collections. Natural Derivatives Library (NDL-3000) elaborates on structural diversity of pure natural molecules and includes natural derivatives, analogs, semi-natural compounds, and mimics. There is no overlap between NPL and NDL compounds. Learn more about the Natural Derivatives Library design approach.
