🧬 Article Summary: Discovery of a New Natural Molecule That Mimics the Effect of Ozempic Without Common Side Effects
A team of researchers at Stanford University, using artificial intelligence, succeeded in discovering a natural molecule called BRP, which works to suppress appetite and reduce weight with an effectiveness similar to the effect of the well-known drug Ozempic or its active ingredient semaglutide. Most notably, this molecule did not show common side effects such as nausea, constipation, or muscle loss, opening new horizons for the precise and proper treatment of obesity.
🧪 How the BRP Molecule Works: A Separate and More Precise Biological Pathway
The effect of BRP is based on activating a distinctive group of neurons within a small, deep area of the brain called the hypothalamus, the region responsible for controlling appetite and metabolism. Unlike Ozempic, which targets receptors found in several organs such as the brain, intestines, and pancreas, causing broad effects throughout the body, BRP manages more precise local control in appetite regulation.
This specificity makes BRP improve appetite and energy expenditure without the negative effects associated with the drug’s actions outside the brain, such as slowed intestinal movement or digestive system problems.
🤖 The Role of Artificial Intelligence in Discovering the BRP Molecule
The research team returned to the proteins known as prohormones, which are inactive precursor molecules that are converted into active hormones by cleaving enzymes known as prohormone convertase 1/3. These enzymes cut proteins into small pieces called peptides, which contribute to the regulation of appetite and metabolism.
The researchers used an innovative computer algorithm they named Peptide Predictor, which was able to scan thousands of human gene proteins to identify the sites that could be cut by the enzyme mentioned.
Narrowing the search led to focusing on 373 potential proteins, from which they were able to predict the production of 2,683 possible peptides, narrowing them further by focusing on their effect on neurons, until reaching 100 peptides tested in the laboratory.
🧠 BRP: Small in Size but Impressive in Effectiveness
Among the tested peptides, BRP produced a cellular response ten times higher compared with untreated cells, despite consisting of only 12 amino acids, making it very small compared with full proteins.
This strong interaction indicates a significant ability to influence brain signals that control appetite and metabolism.
🐭 Testing BRP Effectiveness in Animals
Experiments were conducted on lean mice and miniature pigs that reflect human metabolic patterns. The results showed the following:
- Suppressing food consumption in the hour following BRP injection by up to 50%.
- Treating obese mice for 14 days reduced their weight by about 3 grams, with most of the weight loss coming from fat.
- Compared with the untreated mice, which gained weight over the same period.
- Improvement in glucose and insulin tolerance, indicators of good blood sugar regulation.
Also, the treated mice showed no signs of nausea or constipation, which are common side effects with semaglutide-like drugs. There was also no noticeable muscle loss.
🧬 Biological Differences Between BRP and Semaglutide
BRP does not work in the same biological way as GLP-1 or semaglutide, but rather targets different switches and neural regions. This new mechanism may reduce unwanted effects while preserving the positive effect of reducing appetite.
The researchers are currently working to identify the cell receptors to which BRP binds in order to understand more precisely how it acts, and to map the chain of reactions that occur after it binds to its receptor.
⚙️ Next Challenges: Duration of Effect and Stability in the Body
Like many small peptides, BRP is expected to break down rapidly in the body, which may reduce the duration of its effect. The researchers are currently studying ways to make the molecule more stable to improve its duration of action, which may allow it to be used at less frequent doses if it is approved in the future.
🔬 Future Steps: Toward Human Clinical Trials
At the present time, BRP is still in the preclinical research stage, with preparations underway to conduct trials on humans in the coming period.
The team hopes that the molecule will prove its safety and effectiveness in reducing appetite and promoting weight loss without the side effects that limit the use of current obesity medications.
Developing natural and precisely targeted drugs like this represents important progress in confronting the chronic obesity epidemic with safer and more effective methods.
🧬 Conclusion: The Role of Artificial Intelligence in Discovering New Treatments
This project highlights the importance of artificial intelligence as a crucial tool in analyzing the vast amount of complex biological data, leading to the discovery of new molecules that could bring about a fundamental change in treatment methods, especially in areas such as obesity and metabolic disorders.
Combining modern technology with a precise understanding of the body’s biological mechanisms represents a promising future in developing safer and more effective medicines.
