Synthesis of 6-Methyluracilpentylviologen Resorcinarene Cavitand

Abstract

Resorcinarenes, as macrocyclic compounds, are widely used to recognize substrates and create supramolecular assemblies. Their bowl-like form organizes functional groups at the upper and lower rims, which has a substantial impact on the molecular recognition of various substrates. As a result, resorcinarenes make good drug nanocarrier candidates. This paper presents the synthesis of a new resorcinarene cavitand functionalized along the upper rim with methyluracil and viologen fragments for its potential use in drug delivery. Methyluracils and viologens are well-known receptor-targeted compounds capable of facilitating the vector transfer of drugs and increasing the effectiveness of their action on cells. The paper describes the synthesis of resorcinarene modified with methyluracil and viologen groups along with its structure determined by 1H-, 13C-NMR and IR spectroscopy.
