Bis-cyclohexyl-crown-ethers as allosteric carriers
摘要:
Several bis-cyclohexyl-crown-ethers have been synthesized and used as carriers for alkaline cations. These compounds should all show negative allosteric cooperativity, but only 1 exhibits an odd cation transport behavior across the liquid organic membranes.

The bis-macrocyclic ether5 seems to have a negative allostericcooperativity and is able to transport double the amount of Na+ and K+ cations as monocyclic systems. This compound could be used as a simple model of the plasma membrane Na+−K+ ATPase which actively pumps Na+ out and K+ into the cell, respectively.
