“…The results of this initial screen were as follows. [8] Guanidinium cations were always better than ammonium cations. Activities increased with increasing number of hydrazones until 'octopus amphiphiles' with three (i.e.…”

“…3). [6][7][8][9][10][11] Much stronger than weak interactions such as hydrogen bonds, cation-π or π-π interactions, dynamic covalent bonds still can form an internal target to shift the coupled equilibria according to Le Chatelier.…”

“…For instance, G1H2 was active with T8-T16, G1H3 with T7-T12, G1H4 with T6-T12 and G1H6 with T5-T7. [8] These trends suggested that polyion-counterion complexes of intermediate hydrophobicity are best. Too lipophilic systems tend to precipitate or to disappear in the middle of the membrane, whereas too hydrophilic systems fail to partition into the membrane.…”

“…[6] Scope and limitations of dynamic counterions 11 are currently being explored in lipid bilayer membranes. [7][8][9][10] To elaborate on dynamic counterions 11, initial emphasis was on hydrazones. [7][8][9][10] Peptide dendrons were selected as modular scaffolds and equipped with different numbers of charges and hydrazides (Fig.…”
