Biochemical combinatorial techniques such as phage display, RNA display and oligonucleotide aptamers have proven to be reliable methods for generation of ligands to protein targets. Adapting these techniques to small synthetic molecules has been a long-sought goal. We report the synthesis and interrogation of an 800-million-member DNA-encoded library in which small molecules are covalently attached to an encoding oligonucleotide. The library was assembled by a combination of chemical and enzymatic synthesis, and interrogated by affinity selection. We describe methods for the selection and deconvolution of the chemical display library, and the discovery of inhibitors for two enzymes: Aurora A kinase and p38 MAP kinase.

Figure 3.
(a) Selection output from DEL-A selections against Aurora A kinase. Low occurrence molecules (<4 copies) have been removed. Both selections show lines in the cycle 2 plane corresponding to 6-aminoquinoline. In method A, the line comprises 2-methoxyphenethylamine at cycle 3. In method B, there are two lines corresponding to 3,4-dimethoxyaniline and 4-pyrrolidinopiperidine at cycle 3. (b) Histograms showing the total occurrences of cycle 1 synthons after Aurora A selections. Using both methods, 7-AT is the highest occurring cycle 1 synthon. (c) Structures of synthesized compounds and their activity data. The compounds consist of members of both the 7-AT and the 6-aminoquinoline families. (d) Crystal structure of compound 10 bound to Aurora A kinase, showing the 2-fluorophenethylamine moiety exposed to solvent. Image created in Accelrys DS Viewer Pro 5.0.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time.
