Migrastatin and isomigrastatin analogues have been synthesised in order to contribute to structure–activity studies on tumour cell migration inhibitors. These include macrocycles varying in ring size, functionality and alkene stereochemistry, as well as glucuronides. The synthesis work included application of the Saegusa–Ito reaction for regio‐ and stereoselective unsaturated macroketone formation

We have accomplished the synthesis of ‘hypotheticalmacroketone’ (a novel migrastatin analogue) for the first time. We have used TiCl4 mediated vinylogous Mukaiyama aldol reaction (VMAR) to establish the required three stereocenters on the key intermediate. Grubbs’ 2nd generation catalyzed RCM reaction was utilized to construct the 14 membered ring macrocycle.

Synthesis of highly active migrastatin-based tumor migration cell inhibitors has been accomplished. Our flexible and concise totalsynthesis of migrastatin has allowed us to explore otherwise inaccessible migrastatin-derived structural motifs. This effort has resulted in the discovery of analogues with tumor cell migration inhibitory activity 3 orders of magnitude higher than that of the natural product
In one aspect, the present invention provides a method for treating colon and/or ovarian cancer in a subject comprising administering to a subject in need thereof a compound of general formula (I): wherein R1-R6, R, -R, Q, Y1, Y2 and n are as defined herein, wherein the compound is present in an amount effective to inhibit colon and/or ovarian tumor metastasis.
