Design, synthesis, and characterization of peptide nanostructures having ion channel activity

We report the synthesis and the functional studies of multiple crown α-helical peptides designed to form artificial ion channels. The approach combines the versatility of solid phase peptide synthesis, the conformational predictability of peptidic molecul

Molecular design of crown ethers. VII.1 syntheses and cation selectivities of unsubstituted 12- To 16-crown-4

Solvent extraction of aqueous alkali and some heavy metal picrates with the title compounds showed that, with most cations except for Li+, Na+, and Ag+, the extractability decreases monotonically as the ring size increases from 12 to 16. However, 14-crown-4 showed the highest extractability and selectivity for Li+ over the larger alkali metals, while 15-crown-4 exhibited the highest Ag+/Tl+ selectivity.

SYNTHESIS AND ALKALI METAL CATION COMPLEXATION BY BENZOCROWN ETHERS

New or improved synthetic routes to several benzocrown ethers and alkali metal picrate extraction data for eight benzocrown ethers with varying sizes are reported.
