A series of novel bivalent mimetics of annonaceous acetogenins have been designed, synthesized, and evaluated. Among these, compound 7 bearing a homopiperazine ring in the middle region exhibited more potent growth inhibitory activity and higher selectivity against cancer cells over normal cells by comparison with AA005. This work indicates that modification of the middle piperazine ring is a useful optimizing tool for the simplified acetogenin mimetics.

A small library of analogues of annonaceous acetogenins through click linkage with aromatic moieties is established using a convergent modular fragment-assembly approach. These analogues exhibited low micromolar inhibitory activities against the proliferation of several human cancer cell lines. Structure-activity relationship (SAR) of these analogues indicates that replacement of the methoxy groups of ubiquinone ring with methyl groups is proved to be a useful strategy for improving the anticancer activity of quinone-acetogenin hybrids.

The present invention relates to nitric oxide donor compounds having a quinone based structure, to processes for their preparation and to their use in the treatment of pathological conditions where a deficit of NO plays an important role in their pathogenesis.
Synthesis and characterization of mitoQ and idebenone analogues as mediators of oxygen consumption in mitochondria
Duveau, Damien Y.,Arce, Pablo M.,Schoenfeld, Robert A.,Raghav, Nidhi,Cortopassi, Gino A.,Hecht, Sidney M.
experimental part, p. 6429 - 6441 (2010/10/03)
Analogues of mitoQ and idebenone were synthesized to define the structural elements that support oxygen consumption in the mitochondrial respiratory chain. Eight analogues were prepared and fully characterized, then evaluated for their ability to support oxygen consumption in the mitochondrial respiratory chain. While oxygen consumption was strongly inhibited by mitoQ analogues 2-4 in a chain length-dependent manner, modification of idebenone by replacement of the quinone methoxy groups by methyl groups (analogues 6-8) reduced, but did not eliminate, oxygen consumption. Idebenone analogues 6-8 also displayed significant cytoprotective properties toward cultured mammalian cells in which glutathione had been depleted by treatment with diethyl maleate.
