analysis of synthetic analogues of curacin A revealed the lack of activity of traditional heterocyclic replacements of the thiazoline ring or cyclopropyl analogues of the core diene segment. The significance of the C(3)-C(4)-(Z)-alkene geometry was established, and a novel oxime analogue was designed that displays biological properties that are a close match of the naturalproduct lead. The much less

The present invention provides an efficient synthetic strategy for the preparation of analogs that incorporate important structural elements of the marine natural product curacin A, the compositions and various uses of the compositions. The most active of these compounds at nanomolar concentrations inhibit tubulin polymerization, show growth inhibition activity, inhibited colchicines binding to tubulin and block mitotic progression. The compounds of the present invention represent some of the most potent synthetic curacin A analogs synthesized, with an activity profile rivaling that of the natural product despite the simplified structure, greater water solubility, and increased chemical stability.

The marine naturalproduct curacin A served as the lead compound for the combinatorial synthesis of 6-compound mixture libraries. Fluorous trapping with a vinyl ether tag was used to streamline purification of the heterogeneous multicomponent reaction products and provide chemically clearly defined mixtures. The screening profile of one mixture library, 17mix, was attractive enough to warrant the re-synthesis
