Questions on ZINC

This page contains questions from the ZINC session and the responses provided. 


 

What things are important to consider when using ZINC to order compounds and libraries?

  • Remember to not trust your data, there are errors in every database!
  • Be careful and check the quality of compounds
  • Good vendors can provide spectra to show the quality (this might have an associated cost)
Not all compounds are available as stock from some vendors and they may have to prepare them when ordered
  • This can take lots of time, so be aware of your timeframe
You get what you pay for!
  • Cheap libraries might not be great quality

Can ZINC provide a list of suppliers for each compound?

  • Yes, they are listed alphabetically, so no weighting of which suppliers provide a better service/product

Does SEA store any search information?

  • Yes, just like Google does
  • For privacy concerns you can buy the software and run it locally
  • SEA - Limited by IP address to 40x a day, free to use in single cases
  • For High-Throughput Screening, it is best to purchase a license

If you have 30-50 compounds to test at once, can SEA tell you which pathways you are hitting?

  • No, but it will tell you the target you are hitting
  • Compounds need to be in ChEMBL for SEA to actually return something
  • Natural compounds will return null hits as they are not well defined in chemical space
