Exploring New Chemical Space by Stereocontrolled Diversity-Oriented Synthesis

Diversity-oriented synthesis as a tool for chemical genetics.

Chemical genetics is an approach for identifying small molecules with the ability to induce a biological phenotype or to interact with a particular gene product, and it is an emerging tool for lead generation in drug discovery. Accordingly, there is a need for efficient and versatile synthetic processes capable of generating complex and diverse molecular libraries, and Diversity-Oriented Synthe...

Chemical genetics approach to drug discovery by diversity-oriented synthesis (DOS) of peptidomimetics*

Chemical genetics, which relies on selecting small molecules for their ability to induce a biological phenotype or to interact with a particular gene product, is a new powerful tool for lead generation in drug discovery. Accordingly, diversity-oriented synthesis (DOS) of small-molecule peptidomimetics gives access to collections of new chemotypes bearing high structural diversity. Biological ev...

Converting oxazoles into imidazoles: new opportunities for diversity-oriented synthesis.

We report the optimization of a neglected reaction for the rapid and direct conversion of oxazoles into N-substituted imidazoles. The utility of this microwave-promoted reaction for diversity-oriented synthesis is demonstrated in the preparation of >40 N-substituted imidazoles, including α-imidazolyl esters.

Optimizing Dvl PDZ domain inhibitor by exploring chemical space

Because of advances in the high-throughput screening technology, identification of a hit that can bind to a target protein has become a relatively easy task; however, in the process of drug discovery, the following hit-to-lead and lead optimization still remain challenging. In a typical hit-to-lead and lead optimization process, the analogues of the most promising hits are synthesized for the d...
