Pure Natural Products Library

Natural products remain quite interesting and, often, represent the most exquisite examples of targeted therapies—selected for their activities through evolution. - Charles L. Sawyers

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:

  1. Combinatorial chemistry's promise to fill drug development pipelines with de novo synthetic small-molecule drug candidates is unfulfilled
  2. The practical difficulties of natural products drug discovery are being overcome by advances in separation technologies and in the speed and sensitivity of structure elucidation
  3. A compelling case is being made for the intrinsic utility of natural products as sources of drug leads.

TimTec NPL Featured Screening Results

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.
