Natural Product Discovery Center (NPDC) at Scripps Reseaarch

Natural products are significantly underrepresented in current small molecule libraries.  The current Natural Products Library (NPL) at Scripps Research's Natural Product Discovery Center consists of: (i) purified natural products with fully assigned structures, (b) MPLC (on C-18 semipreparative column) fractions, and (c) crude extracts.  The NPL is presented in 384-well format with all materials dissolved in DMSO (1 mM for pure compounds and 50 mg/mL for fractions and extracts), compatible with most of the HTS platforms.  The NPL currently available for screening includes: (a) ~600 pure natural products, (b) ~53,500 MPLC fractions, (c) ~205,000 crude extracts.  The NPL provides an unprecedented molecular diversity to screen emerging targets for drug leads, and selected members of the NPL serves as outstanding small molecule probes to interrogate biology.  Central to the Natural Products Discovery Center is the large microbial strain collection, containing a total of 217,352 bacterial and fungal strains, of which 62,328 are actinobacteria, 14,465 other bacteria, 92,225 fungi, and 48,334 unidentified (bacteria or fungi).  Promising leads could therefore be produced in sufficient quantities by microbial fermentation for follow up studies and, ultimately, clinical development.

 Lactimidomycin is now available from EMD Millipore (http://www.emdmillipore.com/life-science-research/lactimidomycin/EMD_BIO-506291/p_uuid?WFSimpleSearch_NameOrID=lactimidomycin&BackButtonText=search+results).
