Low Molecular Weight Nucleoside Gelators: A Platform for Protein Aggregation Inhibition

Low molecular weight nucleoside gelators hold great promise in drug delivery and particularly for the delivery of biologics because of their excellent biocompatibility. However, the influence of these gelators on protein aggregation inhibition has not yet been studied. Protein aggregation is the most significant cause of protein instability and can severely impact the biological activity of the protein, impairing the quality and safety of the formulation. Herein, we report the ability of a nucleoside-based gelator, N4-octanoyl-2'-deoxycytidine, to inhibit protein aggregation. Using turbidimetric, spectroscopic, and microscopic methods, we demonstrate that protein aggregation inhibition is dependent on gelator concentration. Moreover, we have found that the protein is still functionally active in the hydrogel.
