Decyl(triphenyl)phosphonium (DTPP) is the organophosphorus cation with the formula C₁₀H₂₁P(C₆H₅)₃⁺. It is a lipophilic quaternary phosphonium cation. It forms the basis for many mitochondrial-targeted drugs, including MitoQ, MitoE, and SkQ. It binds to the mitochondrial matrix by insertion into the inner membrane.^[1]^[2] DTPP itself can cause mitochondrial swelling in kidney tissue, an action possibly related to increased membrane permeability.^[3]
