Preparation of Selenoinsulin as a Long‐Lasting Insulin Analogue

Abstract: Synthetic insulin analogues with a long lifetime are current drug targets for the therapy of diabetic patients. The replacement of the interchain disulfide with a diselenide bridge, which is more resistant to reduction and internal bond rotation, can enhance the lifetime of insulin in the presence of the insulin-degrading enzyme (IDE) without impairing the hormonal function. The [C7U ,C7U ] variant of bovine pancreatic insulin (BPIns) was successfully prepared by using two selenocysteine peptides (i.e., the C7… Show more

“…[10] The need for improved properties in some disulfide-rich systems has motivated chemists to develop and apply various chemical alterations; [11] examples include backbone cyclization or replacement of the disulfides with other moieties. [12] A key challenge in such work is maintaining the precise 3-dimensional fold of a prototype after chemical modification.…”

“…The overarching objective in all these cases is to sway the competition between folding and aggregation to favor rapid folding and burial of hydrophobic residues. Inroads have also been made to introduce disulfide bonds and also replace cysteines with Selenocysteine as potential mechanisms to intramolecularly catalyze disulfide bond formation [49]. Other techniques have explored and exploited pro-domains in catalyzing disulfide-associated folding [50].…”
