Design, synthesis and membrane ion transport properties of cystine- and serine-based cyclo-4-oxa-heptane-1,7-bisamides

A new class of cyclobisamides, having the general profile of amino acid (cystine or serine)-ether composites, as potentially efficient ion transporters has been designed and synthesized. In model membranes, the adamantane harboring composites exhibited 57-66% of gramicidin A activity in ion transport.

The Small Cage 12,17-Dimethyl-5-oxa-1,9,12,17,-tetra-azabicyclononadecane (L): its Synthesis, Characterization, and 'Proton Sponge' Behaviour. The Crystal Structure of the Dipicrate Salt (Picrate)2

The synthesis and characterization of the new oxa-azamacrobicycloalkane 12,17-dimethyl-5-oxa-1,9,12,17-tetra-azabicyclononadecane (L) are described.Its basicity behaviour in both aqueous and water-Me2SO (50:50 mol/mol) solutions has been investigated by potentiometric and spectroscopic (1H and 13 C n.m.r.) techniques.In aqueous solution it behaves as a very strong base (proton sponge) in the first protonation step, and as a relatively strong base in the second step (log k2 = 11.21).In the mixed water-Me2SO solvent both protonation constants have been measured: log k1 = 14.0 and log k2 = 8.2. 1H N.m.r. experiments indicate that in the monoprotonated species H(L)+ the proton is rapidly exchanged with acidic hydrogens on the n.m.r. timescale. 1H-1H and 1H-13C two-dimensional n.m.r. experiments allowed the unequivocal assignment for all the 1H proton and 13C resonances of both species H(L)+ and H2(L)2+.Crystals of (picrate)2 are monoclinic, space group P21/n, a = 12.868(8), b = 17.201(2), c = 16.614(2) Angstroem, β = 110.18(1) deg, and Z = 4; final R values of 0.090 (Rw = 0.090) for 3801 observed reflections.The four basal nitrogen atoms and the apical oxygen atom are located at the apices of a slightly distorted square pyramid.X-Ray analysis shows that the protonation occurs on the NCH3 groups.Each hydrogen atom of the NH+CH3 interacts with the oxygen atom, the O...H distances 2.328(16) and 2.112(18) Angstroem, and with both bridgehead nitrogen atoms, the H...N distances ranging from 2.32 to 2.34 Angstroem.This arrangement makes the overall structure very stable from the thermodynamic point of wiew and explains the unusually high basicity of (L) in both first- and second-protonation step.
