Currently, there is notreatment capable of reversing retinal damage, which represents a significant burden onthe quality of life of patients. (1R)-1-Dodecylsulfonyl-5N,6O-oxomethylidenenojirimycinstands outs as a prototype of the sp2-iminoglycolipids family for its beneficial neuroprotective effect against this chronic eye disease. Critical issues related to the low solubility andbioavailability of this glycolipid in biological settings are overcome by its encapsulation in aZeolitic-Imidazolate Framework (ZIF) structure, resulting in homogeneous and biocompatible GlycoZIF nanoparticles. Cell studies show an enhanced cellular uptake compared withthe free glycolipid, and importantly, its bioactivity is preserved once released inside cells.Methods: Extensive in vitro and ex vivo assays with diabetic retinopathy models unveilthe mechanistic pathways of the designed GlycoZIF. Results: A reduction in proinflammatory mediators, increased heme oxygenase-1 level, inhibition of NLRP3 inflammasome,and reduced reactive gliosis is shown. Conclusions: These findings demonstrate for thefirst time the potential of Glyco-modified ZIFs for the treatment of diabetes-related ocularproblems by controlling the immune-mediated inflammatory response.
