1. Meanwhile, some suppliers of combinatorial chemistry services are expanding into new arenas. 2. Scheme illustrating the theory of protein-directed dynamic combinatorial chemistry ( DCC ). 3. Consequently, at the beginning of the 2000s DNA-combinatorial chemistry experienced a revival. 4. The methods used in combinatorial chemistry are applied outside chemistry, too. 5. These include fragment-based lead discovery ( FBDD ) and protein-directed dynamic combinatorial chemistry . 6. Similar to combinatorial chemistry , compounds are produced by biosynthesis rather than organic chemistry. 7. Thus, Glaxo, Eli Lilly and Hoechst have all snapped up small combinatorial chemistry companies. 8. The Pictet Spengler reaction has been applied to solid-phase combinatorial chemistry with great success. 9. The advent of combinatorial chemistry has enabled drugs in relatively short periods of time. 10. These techniques are complemented by laboratory methods from combinatorial chemistry , molecular biology and functional genomics.
