Synthetics

The Open Chemical Repository Collection

DTP maintains a repository of synthetic compounds and natural products that are openly available to investigators for research purposes in limited quantities based on inventory. Samples are available at no cost except for shipping charges. It is a uniquely diverse collection of more than 140,000 compounds that have been either submitted to DTP for biological evaluation from a variety of sources worldwide or, in some cases, synthesized under DTP auspices. Importantly, investigators should note that chemical structures of these substances are those assigned by the originator of the material and in the vast majority of cases, the compounds have not been analyzed by DTP for accuracy of structure or for the purity of the sample. Compounds are available through a web-based ordering system; instructions are located at the bottom of this page. It is requested that any publication resulting from use of a sample acknowledge the source of the material as “The NCI/DTP Open Chemical Repository” and include the DTP website address, http://dtp.nci.nih.gov , and the NSC number of the agent.

Compounds are available as either individually vialed samples or in plated 96-well format for screening. The quantity available for distribution in vials will be determined by the current inventory. In addition, the 5 focused NCI plated sets below are available.

Procedures for Requesting Samples

DTP distributes samples from the Open Chemical Repository exclusively through a web-based ordering system. Potentially available compounds can be searched by name or NSC number using the “Data Search” function at the DTP homepage, http://dtp.nci.nih.gov . The availability of some samples may be limited by current inventory. Procedures and on-line ordering information are accessible by clicking the links below. The overall process (See Image) is summarized in the printable flow diagram to the left.

Please note that an individual with the appropriate signatory authority from the investigator's organization will be required to accept an on-line Simple Letter of Agreement (SLA) for material transfer before the compound order is forwarded for DTP approval. The SLA appears at the end of the ordering process and will be sent electronically by DTP to the designated signatory authority. Vialed samples or plated sets are generally shipped within a week after the order is approved by DTP staff.

Requestors should have the following required information prior to starting the ordering process.

  • Requestor's contact/shipping information
  • A Fedex number for shipping charges
  • NSC number of sample (use “Data Search” at DTP homepage)
  • Amount of sample in milligrams to be requested
  • Intended use of sample (e.g. CDK screening assay standard)
  • Contact information, including e-mail, of Organization's signatory authority for accepting Simple Letter of Agreement (SLA)
