Apoptosis-inducing activity of a fluorescent barrel-rosette M⁺/Cl^- channel.

ABSTRACT: Synthetic transmembrane ion transport systems are emerging as new tools for anticancer therapy. Here, a series of 2-hydroxy-N 1,N 3-diarylisophthalamide-based fluorescent ion channel-forming compounds are reported. Ion transport studies across large unilamellar vesicles confirmed that the compound with two 3,5-bis(trifluoromethyl)phenyl arms is the most efficient transporter among the series and it facilitates M+/Cl- symport. The compound formed supramolecular ion channels with a single-channel conductance of 100 ± 2 pS, a diameter of 5.06 ± 0.16 Å and a permeability ratio, P Cl- /P K+ , of 8.29 ± 1. The molecular dynamics simulations of the proposed M2.11 c
