The synthesis, complexation properties and catalytic activities under phase-transfer (PT) conditions of differently substituted cyclohexapeptoids are reported. Association constants, for small cationic alkali, and catalytic performances, in a model nucleophilic substitution, are comparable to those of representative crown ethers. Noteworthy
A potassium carrying ionophore dicyclohexano-18-crown-6 was found to affect the specific ionic currents in the node of Ranvier. Its presence caused an inactivation of the potassium permeability mechanism and a decrease of the sodium permeability. The rate of inactivation of

The effects of some potassium channel blockers on the ionic currents and on the so-called K(+)-depolarization in intact myelinated nerve fibres were studied. 4-AP, and in particular, Flaxedil, proved to be selective K(+)-current blockers. However, TEA, a crown ether (DCH18C6)
