NEW LIBRARIES ADDED IN 2022:

  • 8,387 bioactives – TargetMol library

    • known bioactives from TargetMol
    • these are annotated with a characterized target or mechanism of action. It includes the FDA-approved collection and drugs for repurposing.
    • For graphs depicting what all is in this library, look at the PDF here. For example, below is a graph showing the representation of different biomedical research area applications for the compounds in this library and another with the clinical status of the compounds.a pie chart showing the biomedical research areas covered by the TargetMol library. They largest piece is cancer, which is about a third. a pie chart shows half not clinical and of the rest, one third FDA approved, one third approved in other countries, and one third in clinical trials.
  • 64,000+ diversity compounds – ChemDiv library
    • “preplated” synthetic and semi-synthetic diversity compounds from ChemDiv
    • these have drug-like properties and are predicted to have a variety of activities. They cover many scaffolds and analogs around each scaffold.
    • on our freezer bottom shelf, 200 Labcyte PP microplates in 384 well format – daughter plating in progress
    • additional targeted diversity libraries are currently being assembled to include [note that this is on hold until more funds can be procured]:
      • natural-product-like molecules
      • steroid-like molecules
      • predicted protease inhibitors
      • predicted antibacterials
      • predicted protein-protein-interaction modulators
  • 762 fragments – Gardner library
    • NMR-based fragment library from Kevin Gardner’s lab at CUNY
    • Plated to Labcyte plates ready for Echo or pinning! in our freezer. Source vials are in the Partch lab -80.
    • 20 mM stocks in DMSO
  • Natural products
    • new or expanded collections of botanical and microbial natural product extracts and fractions
    • from the labs of John MacMillan, Laura Sanchez, and others
    • actively being screened in various bioassays under way by the CSC staff and several researcher teams
    • a goldmine for new pharmaceutical agents and tool compounds!
  • >5,000 (and growing!) natural product-inspired cell-permeable cyclic peptides – Lokey
    • DMSO stocks formatted in 384 well AB-GENE plates, reformatted from 96-well plates using the Janus MDT.

About our libraries

We house a collection of commercially available compounds and a unique growing collection of marine and terrestrial natural products from collaborations. These libraries are available to any user of our equipment for the purpose of assays conducted in our center. We also allow users to cherry pick a few compounds of interest for follow-up assays. We charge a fee for use of a library or for 1ul of a compound. Unless otherwise noted, our libraries are currently at 10 mM in 100% DMSO and stored either in -20 degrees (click for -20 inventory) or in a room temperature desiccator. They are heat-sealed with foil covering to prevent moisture from entering or compound cross-contamination. We have accumulated a reference database of results collected for our compounds in a variety of assays, including cytotoxicity data in a variety of cells (microbial and mammalian) and cytological profiling for guilt-by-association mechanism of action identification of a novel compound.

Structural information of chemical libraries are often created in structural data file (SDF) format.

  • Here is a description of what SDF files are and a list of software that open them. On the Life Chemicals website.
  • Here you can find a comparison of the various software available, made at UC Santa Barbara.
  • Here is a 13-page PDF from the NIH to guide you in working with SDF files
  • Here is the download link for Data Warrior, the software used by Beverley to view SDF files. Below is a screenshot of what the software looks like, with our newest ChemDiv focused libraries showing.
