Macrocyclic ketone analogues of halichondrin B

Synthesis and SAR studies of structurally simplified analogues of marine natural product halichondrin B resulted in the discovery of E7389, a new potential antitumor agent currently undergoing Phase I clinical trials. Structurally simplified macrocyclic ketone analogues of halichondrin B were prepared by total synthesis and found to retain the potent cell growth inhibitory activity in vitro, stability in mouse serum, and in vivo efficacy of the natural product.
