Design and synthesis of 3′,5′-ansa-adenosines as potential Hsp90 inhibitors
摘要:
3',5'-Ansa-adenosine derivatives, rationally designed as an Hsp90 inhibitor by extracting and fusing a natural product, geldanamycin, and a natural substrate, ATP, were efficiently synthesized by the ring-closing metathesis assisted by the 2,4-dimethoxybenzyl group. This simpler scaffold design provides a practical synthesis of a set of analogs and demonstrates synthetic innovation. (C) 2009 Elsevier Ltd. All rights reserved.
