Bisphosphonic salts with C12-chains, such as 1,12-bis(tributylphosphonium)dodecyl dibromide 2 (Figure 1), exhibited moderate phospholamban (PLB) inhibition and antifungal activity.21 Delikatny et al. investigated the effect of a triphenyl-containing salt, and tris(4-dimethylaminophenyl) mono- and bisphosphonium salts with short carbon chains on breast cancer cells, DU-4475 and HBL-100, and the triphenyl derivative exhibited selective growth inhibition.15 This evidence concerns the gene PLN and breast carcinoma.
