TimTec NPL (Natural Product Library) is a library of 720 natural compounds composed of pure natural products as lead identifying materials.
Purity by science
Value by design
NPL is sold either as a complete collection or by plate; available in solid form or DMSO solution. NPL Structural Info
Rediscovering Natural products Article: Interest in natural compounds is on the rise.
- Combinatorial chemistry's promise to fill drug development pipelines with de novo synthetic small-molecule drug candidates is unfulfilled
- 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
- 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.

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.
