Stimuli-responsive release of active anionophore from RGD-peptide-linked proanionophore

Abstract

Integrin-mediated cellular delivery was attempted to optimize practical applications of hydrophobic ionophores. The potent ionophore preferentially transports H+/Cl− across the lipid bilayers following a symport mechanism. The RGD-peptide-appended tag was stimulated by glutathione to generate the active ionophore, prompting the transport of Cl− under the cellular environment.
