A new series of anticancer annonaceous acetogenin mimetics were designed, synthesized, and evaluated based on our previously developed compound AA005, in which a variety of conformationally constrained fragments were introduced. Parallel syntheses of all new compounds were accomplished by replacement of the acyclic bis-ether functionality of AA005 with certain conformationally constrained fragments. Slight effects to the anticancer activity were exerted by alteringstereochemistries in the middle modification region. Similar to AA005, most newly synthesized mimetics were found to exhibit potent activities against breast cancer cells, and showed satisfactory selectivities between cancerous and non-cancerous cells. An N,N′-di-methyl bis-amide compound 67 exhibits 30 times more potency against MDA-MB-468 cells than its parent molecule AA005. This study indicates that the introduction of appropriate conformational constraints is a useful optimizing tool for this class of anticancer agents. Successes in the bisamide analogues of AA005 make this unique class of anticancer agents much simpler and more flexible for future further developments.
