Thai readers could benefit from safer obesity therapies as brain pathway research advances
A new class of weight‑loss compounds targets a different brain pathway and has shown promising results in animal studies. The engineered molecule reduces appetite and improves insulin response without the nausea that often accompanies current drugs. Researchers identified a peptide called octadecaneuropeptide (ODN) produced by support cells in the hindbrain, then designed a drug-like derivative, tridecaneuropeptide (TDN). In obese mice and emesis-capable musk shrews, TDN reduced food intake and improved glucose handling without triggering sickness. The work highlights a potential path to obesity and diabetes therapies that may be easier for patients to tolerate and for health systems to deliver.
