ABSTRACT
As a novel branch of combinational chemistry, dynamic combinatorial chemistry (DCC) can be viewed as a technique which combines library synthesis and screening in one pot. By addition of molecular target, ligangds, which show binding affinity or strong interaction with the molecular target, can be amplified an young but rapidly growing branch of combinatorial chemistry, has been widely used in organic chemistry, biochemistry, material fields. Ligands in the library can be amplified, since synthesis of the library is screened by a molecular target. Therefore, these structures could be identified easily. Consequently DCC has been widely used in the lead discovery, material chemistry and other fields. On the basis of the principle and method of DCC, this review emphasizes the three factors of DCC, including molecular targets (bio-enzyme, lectin, nucleic acid, organic molecule, inorganic molecule); reaction (disulphide chemistry, ammoniation reduction reaction, hydrazone chemistry, etc.) and analytical method. Meanwhile, limitation, current situation and future development of DCC were also discussed in this paper.
