The F2X-Entry Screen is a subset of the F2X-Universal Library

However, for compound libraries witheven smaller compounds (about five to seven non-hydrogenatoms) higher hit rates were reported

the PanDDA approachincreased the hit yield significantl

Of these, 10 hits (10 binding events) were observed onAar2, 11 hits (12 binding events) on RNaseH, and 1 hit (one bind-ing event) at the functional interface of the two proteins

Chemdiv and Enamine,

During the fragment hit-to-lead process, we typically synthesize 50–100 compounds to increase the binding affinity from millimolar to nanomolar, and we routinely generate multiple lead series for each target

emphasizing X-ray crystallography.

the most potent fragment is often not the best starting point for hit-to-lead chemistry.

Although better cross-validation would provide increased confidence in fragment hits, there is a danger that this may also result in the systematic selection of more potent hits,

great importance should be placed on accurately characterizing the solubility of a fragment library

observe a correlation of 30–40% using these two techniques.

use ligand-observed NMR

Another area of active debate centres on the lack of correlation of fragment hits obtained using different detection techniques

that current fragment libraries are largely composed of ‘flat structures’

our results support the view that less complex molecules give a higher hit rat

Dynamic properties of PPAR-γ

Enzalutamide is an inhibitor of androgen-receptor signaling that exerts its activity by binding avidly to the ligand-binding domain of the androgen receptor, competing with and displacing the natural ligands of this receptor (testosterone and dihydrotestosterone)

A 2 fold molar excess of peptide was added to the protein prior to crystallization (RGAFQNLFQSV).
