Vezse P, Benda B, Fekete A, Golcs Á, Tóth T, Huszthy P. Covalently Immobilizable Tris(Pyridino)-Crown Ether for Separation of Amines Based on Their Degree of Substitution. MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27092838. [PMID: 35566195 PMCID: PMC9103866 DOI: 10.3390/molecules27092838] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Revised: 04/19/2022] [Accepted: 04/27/2022] [Indexed: 11/17/2022]
Abstract
A great number of biologically active compounds contain at least one amine function. Appropriate selectivity can only be accomplished in a few cases upon the substitution of these groups, thus functionalization of amines generally results in a mixture of them. The separation of these derivatives with very similar characteristics can only be performed on a preparative scale or by applying pre-optimized HPLC methods. A tris(pyridino)-crown ether was designed and synthetized for overcoming these limitations at a molecular level. It is demonstrated, that this selector molecule is able to distinguish protonated primary, secondary and tertiary amines by the formation of reversible complexes with different stabilities. This degree of substitution-specific molecular recognition of amines opens the door to develop separation processes primarily focusing on the purification of biologically active compounds in a nanomolar scale.

Abstract
![]()
We report a macrocyclic
ligand (H3L6) based
on a 3,6,10,13-tetraaza-1,8(2,6)-dipyridinacyclotetradecaphane
platform containing three acetate pendant arms and a benzyl group
attached to the fourth nitrogen atom of the macrocycle. The X-ray
structures of the YL6 and TbL6 complexes reveal nine coordination
of the ligand to the metal ions through the six nitrogen atoms of
the macrocycle and three oxygen atoms of the carboxylate pendants.
A combination of NMR spectroscopic studies (1H, 13C, and 89Y) and DFT calculations indicated that the structure
of the YL6 complex in the solid
state is maintained in an aqueous solution. The detailed study of
the emission spectra of the EuL6 and TbL6 complexes revealed
Ln3+-centered emission with quantum yields of 7.0 and 60%,
respectively. Emission lifetime measurements indicate that the ligand
offers good protection of the metal ions from surrounding water molecules,
preventing the coordination of water molecules. The YL6 complex is remarkably inert with respect to complex dissociation,
with a lifetime of 1.7 h in 1 M HCl. On the other hand, complex formation
is fast (∼1 min at pH 5.4, 2 × 10–5 M).
Studies using the 90Y-nuclide confirmed fast radiolabeling
since [90Y]YL6 is
nearly quantitatively formed (radiochemical yield (RCY) > 95) in
a
short time over a broad range of pH values from ca. 2.4 to 9.0. Challenging
experiments in the presence of excess ethylenediaminetetraacetic acid
(EDTA) and in human serum revealed good stability of the [90Y]YL6 complex. All of these
experiments combined suggest the potential application of H3L6 derivatives as Y-based radiopharmaceuticals. A new versatile asymmetric ligand based
on an 18-membered
macrocycle possessing three acetate pendant arms and a benzyl moiety
provides fast complexation with both natY(III) and 90Y(III), as well as slow dissociation kinetics. A detailed
structural study in the solid state and in solution evidences nona
coordination of the metal ion by the ligand, offering good protection
from solvent water molecules. These favorable properties make this
ligand an attractive candidate to develop yttrium-based radiopharmaceuticals.
