Insulin-Degrading Enzyme: Paradoxes and Possibilities
Although these paradoxes are by definition unresolved, the author offers herein his personal insights and informed speculations based on two decades working on the biology and pharmacology of IDE and suggest specific experimental strategies for addressing these conundrums.
Hydroxypyridinethione Inhibitors of Human Insulin‐Degrading Enzyme
- Biology, ChemistryChemMedChem
In an effort to discover new, zinc‐targeting inhibitors of IDE, a library of ∼350 metal‐binding pharmacophores was screened against IDE, resulting in the identification of 1‐hydroxypyridine‐2‐thione (1,2‐HOPTO) as an effective Zn2+‐binding scaffold.
Reassessment of an Innovative Insulin Analogue Excludes Protracted Action yet Highlights Distinction between External and Internal Diselenide Bridges.
Although [C7UA , C7UB ] does not confer protracted action, nonetheless its comparison to internal diselenide bridges promises to provide broad biophysical insight.

Multimodal Chemical Imaging of Amyloid Plaque Pathology in Alzheimer’s Disease
- Biology, Chemistry
Aβ plaque pathology is much more complex than what it is currently considered during ordinary post-mortem neuropathological assessments and needs to be researched with the help of advanced methods, to provide important information about how, where and why Aβ and other biomolecular factors contribute to the development of AD.

Four specifically designed IDE mutants have been used to unveil the molecular basis of peptidase versus E1-like activity of the enzyme. We have found that physiological concentrations of copper(ii)…
The core sequence of PIF competes for insulin/amyloid β in insulin degrading enzyme: potential treatment for Alzheimer's disease
A new pregnancy derived peptide, PreImplantation Factor (PIF), inhibits neuro-inflammation and crosses the blood-brain-barrier and the predicted RIKP sequence and especially the specific I4 and P6 amino acids are essential for hydrophobic interactions with the IDE complex.
