Individual Compounds and Custom Compound Collections

In addition to pre-designed screening collections, you are welcome to choose any number of samples from TimTec database of screening compounds based on your own criteria. Compounds from TimTec pre-designed libraries are also available for cherry-picking. ActiMol Stock library contains >100,000 compounds (1-2 weeks delivery time). Overseas stock inventory is over 500,000 compounds (1-2 months delivery).

Drug-like Characteristics of TimTec Stock Compounds

TimTec stock compounds possess drug-like characteristics and undergo multistep filtration to be included in pre-designed libraries. LogP, Molecular weight, number of H-bond donors and acceptors as set forth in the Lipinski "Rule of Five" guide in determining strong hit and lead development characteristics.

Lipinski rule of five requirements
H-bond donors < 5
H-bond acceptors < 10
Log P < 5
Mol. Weight < 500 

Lipinski Rule of Five Chart
1 - compounds which satisfy 1 requirement - 1% of all compounds
2 - compounds which satisfy 2 requirements 2% of all compounds
3 - compounds which satisfy 3 requirements 6% of all compounds
4 - compounds which satisfy all 4 requirements 91% of all compounds

Our compound collections offer greater diversity as we have balanced the combination of in-house synthesis and outside sourcing. Our researchers ensure a high diversity score from collection to collection. We prefer avoiding combinatorial chemistry approach in library design and all our molecules are hand-synthesized. Our compounds are stored in dry form and are freshly prepared in DMSO.  TimTec offers a variety of screening collections to suit different in capacity and design/purpose assays. Chemical compounds in our library collections are available for re-supply from our US stock.

Quality Control and Compound Purity

TimTec determines structure and purity of all compounds by using NMR and mass spectrometry. Our compounds have an average purity of 95%, and the minimum purity is at least 90%. We randomly check the quality of our stock compounds on a regular basis to confirm stability and shelf life. 1H-NMR spectra are available upon request for all stock compounds.
