摘要
Five heptapeptide derivatives, [CH3(CH2)(17)](2)NCO-CH2OCH2CO-Gly- Gly- Gly- Pro- Gly- Gly- Gly- OR, in which R = ethyl, 2- propyl, heptyl, benzyl, and cyclohexylmethyl, were found to transport chloride anion through a phospholipid bilayer to varying extents dependent on the identity of R. It was concluded that the R group is a membrane anchor for the synthetic chloride channels.
