Discovery and structural optimization of pyrazole derivatives as novel inhibitors of Cdc25B
摘要:
Structural optimization and preliminary structure-activity relationship studies of a series of N-substituted maleimide fused-pyrazole analogues with Cdc25B inhibitory activity, starting from a high-throughput screening hit, are illustrated. A simplified 3,5-diacyl pyrazole analogue was obtained as the most potent compound (118, IC50 = 0.12 mu M) with a 270-fold increase in potency. (C) 2010 Elsevier Ltd. All rights reserved.

DNA-encoded chemical libraries are increasingly being employed for the identification of binding molecules to protein targets of pharmaceutical relevance. Here, we describe the synthesis and characterization of a DNA-encoded chemical library, consisting of 4000 compounds generated by Diels-Alder cycloaddition reactions. The compounds were encoded with unique DNA fragments which were generated through
Trifluoromethylation of olefins and (hetero)aromatics with sodium triflinate as CF3 source and readily accessible benzophenone derivatives as photosensitisers has been developed in batch and flow.
