DSi-Poised Library (Live)

​The design principle of the DSi-P (Diamond-SGC-iNEXT Poised) library is to allow rapid, cheap follow-up synthesis to provide quick SAR data. Poised fragments contain at least one functional group which can be synthesised using a robust, well-characterised reaction. Reactions include amide couplings, Suzuki-type aryl-aryl couplings and reductive aminations.

The library was designed by analysing all of commercially available fragment space for poised-ness and selecting a chemically diverse subset which is aligned with the availability of compounds in Enamine REAL Database.

Validation of the DSPL was published in Chemical Sciences: for one challenging target, the second bromodomain of PHIP, the first ever reported hits were obtained by XChem screening; two hits were poised and were followed up accordingly, yielding compounds with improved potency in the sub-100uM range and showing good ligand efficiency - and of course detailed structural data.

This library can be ordered directly from Enamine.
