Goodman and Gilmans: The Pharmacological Basis of Therapeutics, 12e

The D-retro-inverso design replaces all L-amino acids with D-amino acids and reverses the sequence a structural strategy that preserves the side-chain topology of the original FOXO4 binding region while making the peptide resistant to proteolytic degradation, dramatically extending plasma half-life compared to the natural L-form

In addition, serum half-life does not necessarily reflect urine concentrations, which is the main way they take samples for drug testing

Due to its fast reaction rate, the reaction between Ellman's reagent and thiol groups is widely used to measure thiol concentrations in biological and chemical systems
