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.

Hydrogen Bond-Mediated Conjugates Involving Lanthanide Diphthalocyanines and Trifluoroacetic Acid (Lnpc 2@TFA): Structure, Photoactivity, and Stability. Molecules 2020; 25:molecules25163638. [PMID: 32785132 PMCID: PMC7463839 DOI: 10.3390/molecules25163638] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2020] [Revised: 08/03/2020] [Accepted: 08/07/2020] [Indexed: 11/16/2022] Open
Abstract
The interaction between lanthanide diphthalocyanine complexes, LnPc2 (Ln = Nd, Sm, Eu, Gd, Yb, Lu; Pc = C32H16N8, phthalocyanine ligand) and trifluoroacetic acid (TFA) was investigated in benzene, and the stability of the resulting molecular system was assessed based on spectral (UV-Vis) and kinetic measurements. Structural Density Functional Theory (DFT) calculations provided interesting data regarding the nature of the bonding and allowed estimating the interaction energy between the LnPc2 and TFA species. Conjugates are created between the LnPc2 and TFA molecules via hydrogen bonds of moderate strength (>N∙∙H··) at the meso- -bridges of the Pc moieties, which renders the sandwich system to flatten. Attachment of TFA is followed by rearrangement of electronic density within the chromophore system of the macrocycles manifested in considerable changes in their UV-Vis spectra and consequently the color of the studied solutions (from green to orange). The LnPc2@TFA conjugates including Nd, Sm, Eu, and Gd appeared evidently less photostable when exposed to UV radiation than the related mother compounds, whereas in the case of Yb and Lu derivatives some TFA-prompted stabilizing effect was noticed. The conjugates displayed the capacity for singlet oxygen generation in contrast to the LnPc2s itself. Photon upconversion through sensitized triplet-triplet annihilation was demonstrated by the TFA conjugates of Nd, Sm, Eu, and Gd.

Abstract
The coordination properties of the macrocyclic receptor N,N'-bis[(6-carboxy-2-pyridyl)methylene]-1,10-diaza-15-crown-5 (H(2)bp15c5) towards the lanthanide ions are reported. Thermodynamic stability constants were determined by pH-potentiometric titration at 25 °C in 0.1 M KCl. A smooth decrease in complex stability is observed upon decreasing the ionic radius of the Ln(III) ion from La [log K(LaL) = 12.52(2)] to Lu [log K(LuL) = 10.03(6)]. Luminescence lifetime measurements recorded on solutions of the Eu(III) and Tb(III) complexes confirm the absence of inner-sphere water molecules in these complexes. (1)H and (13)C NMR spectra of the complexes formed with the diamagnetic La(III) metal ion were obtained in D(2)O solution and assigned with the aid of HSQC and HMBC 2D heteronuclear experiments, as well as standard 2D homonuclear COSY and NOESY spectra. The (1)H NMR spectra of the paramagnetic Ce(III), Eu(III) and Yb(III) complex suggest nonadentate binding of the ligand to the metal ion. The syn conformation of the ligand in [Ln(bp15c5)](+) complexes implies the occurrence of two helicities, one associated with the layout of the picolinate pendant arms (absolute configuration Δ or Λ), and the other to the five five-membered chelate rings formed by the binding of the crown moiety (absolute configuration δ or λ). A detailed conformational analysis performed with the aid of DFT calculations (B3LYP model) indicates that the complexes adopt a Λ(λδ)(δδλ) [or Δ(δλ)(λλδ)] conformation in aqueous solution. Our calculations show that the interaction between the Ln(III) ion and several donor atoms of the crown moiety is weakened as the ionic radius of the metal ion decreases, in line with the decrease of complex stability observed on proceeding to the right across the lanthanide series.
