Natural Compound 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 a library of 800 natural compounds composed of pure natural products as lead identifying materials. Compounds are primarily sourced from plants with the remaining samples from bacteria, fungus, and animal sources.

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: Interest in natural compounds is on the rise.

  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.
