Identification of a Small Molecular Insulin Receptor Agonist With Potent Antidiabetes Activity

Abstract: Insulin replacement therapy is a widely adopted treatment for all patients with type 1 diabetes and some with type 2 diabetes. However, injection of insulin has suffered from problems such as tissue irritation, abscesses, discomfort, and inconvenience. The use of orally bioactive insulin mimetics thus represents an ideal treatment alternative. Here we show that a chaetochromin derivative (4548-G05) acts as a new nonpeptidyl insulin mimetic. 4548-G05 selectively activates an insulin receptor (IR) but not insuli… Show more

“…100 nM insulin produced highest effect while it was 250 nM in the case of dmp (Fig 3B and 3C). Interestingly, both dmp and insulin were found to be active at nM dose, this was not observed with other insulin mimetic compounds which were active at μM dose in in vitro experiments [3135]. Similar trend was observed with tyrosine kinase activity of IR by dmp and insulin (Fig 3D).…”

“…Association of small insulin mimetic molecule with IR followed by its activation has been reported previously by many authors [3135]. However, a direct binding to IR by a small molecule as its ligand is still not available.…”

“…Protein based therapeutic development, which dates back 30 years to the introduction of recombinant insulin, has also benefited from the application of HDX-MS [61]. The oligomeric state and stability of insulin analogs were monitored with HDX-MS in back to back reports, and demonstrated to be predictive of pharmacokinetic properties such as onset and duration [62, 63].…”

“…При пероральном введении 4548-G05 ин-тактным мышам и мышам с экспериментальными СД1 и СД2 наблюдается сильный гипогликемиче-ский эффект [29]. Производные инозитола также обладают инсулиноподобными эффектами и усили-вают проведение сигнала от ИР [30].…”
