Alteration in mitochondrial transmembrane potential (ΔΨ(m)) is an important characteristic of cancer. The observation that the enhanced negative mitochondrial potential is prevalent in tumor cell phenotype provides a conceptual basis for development of mitochondrion-targeting therapeutic drugs and molecular imaging probes.

Multidrug resistance, especially multidrug efflux mechanisms that extrude structurally unrelated cytotoxic compounds from the cell by multidrug transporters, is a serious problem and one of the main reasons for the failure of therapeutic treatment of infections by pathogenic microorganisms as

A unique phenomenon of mitochondria-targeted protonophores is described. It consists in a transmembrane H(+)-conducting fatty acid cycling mediated by penetrating cations such as 10-(6'-plastoquinonyl)decyltriphenylphosphonium (SkQ1) or dodecyltriphenylphosphonium (C(12)TPP). The phenomenon has been modeled by molecular dynamics and directly proved by
