Abstract
Platinum(II) N-heterocyclic carbene complexes based on 2-chloroadenosine were synthesized. The reaction of 2-chloro-2',3',5'-tri-O-acetyladenosine 1 with Pt(PPh3)4 by C-Cl oxidative addition yielded complex 2, with a PtII centre bonded to the C-2 of the purine ring. Complex 2 was reacted with methyl iodide to yield N-heterocyclic carbene 3, which was subsequently deprotected under basic conditions to provide N-heterocyclic carbene 4, bearing a fully deprotected ribose . The compounds were tested for their cytotoxic activity in five different cell lines: L929, HEK293, A375, MDA-MB-231, and MCF-7. Among the platinum compounds, compound 2, the neutral compound bearing an anionic adenosyl ligand, provides the highest cytotoxic activity, particularly against the A375 and MDA-MB-231 cell lines. Encapsulation of compound 2 with nanostructured lipid carriers does not lead to an improvement on the cytotoxic activity.
期刊介绍:
Quality research. Outstanding publications. With an impact factor of 3.124 (2019), ChemMedChem is a top journal for research at the interface of chemistry, biology and medicine. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies.
ChemMedChem publishes primary as well as critical secondary and tertiary information from authors across and for the world. Its mission is to integrate the wide and flourishing field of medicinal and pharmaceutical sciences, ranging from drug design and discovery to drug development and delivery, from molecular modeling to combinatorial chemistry, from target validation to lead generation and ADMET studies. ChemMedChem typically covers topics on small molecules, therapeutic macromolecules, peptides, peptidomimetics, and aptamers, protein-drug conjugates, nucleic acid therapies, and beginning 2017, nanomedicine, particularly 1) targeted nanodelivery, 2) theranostic nanoparticles, and 3) nanodrugs.
