General description

The insulin receptor is a tyrosine kinase receptor that when bound to insulin, initiates multiple signal transduction pathways, including JNK, PI 3-kinase, Akt and PKC. Pharmacological intervention of these Insulin R-dependent pathways is of great interest for the treatment of insulin resistance, obesity and diabetes. The Insulin Receptor (IR) is synthesized as a single polypeptide, which is subsequently cleaved to generate an extracellular α-chain and a transmembrane and intracellular β-chain, tethered together by disulfide bonds. The β-chain has multiple tyrosine phosphorylation sites, including three autophosphorylation sites at its activation loop. The overall structure of the IR is highly homologous to the IGF-I Receptor, except in their c-termini, where the two proteins diverge somewhat. The IR signals primarily by phosphorylating the Insulin Receptor Substrate (IRS) family of proteins, which creates docking sites for SH2-domain containing proteins. Insulin signaling is highly dependent on the PI3 Kinase pathway and Akt, which appear to mediate the functions of insulin.

An in-depth study on the inhibitory mechanism on protein tyrosine phosphatase 1B (PTP1B) and aldose reductase (AR) enzymes, including analysis of the insulin signalling pathway, of phosphoeleganin, a marine-derived phosphorylated polyketide, was achieved. Phosphoeleganin was demonstrated to inhibit both enzymes
