Mitochondrial complex II (CII) is an emerging target for numerous human diseases. Sixteen analogues of the CII inhibitor natural product atpenin A5 were prepared to evaluate the structure–activity relationship of the C5 pyridine side chain. The side chain ketone moiety was determined to be pharmacophoric, engendering a bioactive conformation. One analogue, 1-(2,4-dihydroxy-5,6-dimethoxypyridin-3-yl)hexan-1-one (16 c), was found to have a CII IC50 value of 64 nm, to retain selectivity for CII over mitochondrial complex I (>156-fold), and to possess a ligand-lipophilicity efficiency (LLE) of 5.62, desirable metrics for a lead compound. This derivative and other highly potent CII inhibitors show potent and selective anti-proliferative activity in multiple human prostate cancer cell lines under both normoxia and hypoxia, acting to inhibit mitochondrial electron transport.

, p. 408 - 409 (2007/10/03)
A concise total synthesis of 7-demethylpiericidin A1 has been completed. The synthesis features a titanium(II)-mediated cyclization of a (silyloxy)enyne as the key step and proceeds in nine steps from tiglic aldehyde. Copyright
