    摘要: Sarcodictyin A and B, eleutherobin, and bioactive analogs (A) thereof synthesized using solid phase and solution phase chemistries. The synthetic method employs an attachment of common precursors, e.g., compounds 1880 or 200, on a solid support for generating conjugates 230 and 240, followed by standard chemical manipulations. A combinatorial library of sarcodictyins and eleutherobin analogs is constructed with modified C-8 ester, C-15 ester and C-4 ketal functionalities and is screened for activity with respect to tubulin polymerization and cytotoxic activity against tumor cells, including Taxol-resistant lines. Compounds 600, 610, 630, 660-700, 730, 760, 850, and 920 are identified to be of equal or superior biological activities as compared to their corresponding natural product.
