Speeding up the hunt for anti-aging compounds

Sat May 10 2025
A new method has been developed to quickly test natural compounds for their ability to fight harmful substances linked to aging and disease. These substances, known as advanced glycation end products or AGEs, build up in the body due to high sugar intake and speed up the aging process. The problem is that testing how well a compound can stop AGEs from forming is a slow process. This is where the new method comes in. Researchers created a 3D model of human liver cells that produce high levels of AGEs. These cells were then turned into a special bio-ink and placed in a tiny, lab-on-a-chip device. This device mimics the natural environment of the liver and allows for quick and sensitive testing of compounds. The entire process takes less than 2. 5 hours, which is a significant improvement over traditional methods that can take up to 500 hours. The new method was used to test several natural compounds. Two of them, alisol B 23-monoacetate and chlorogenic acid, showed promise as potential AGEs inhibitors. This means they could potentially slow down the aging process and reduce the risk of age-related diseases. The combination of high-AGE bio-ink and the microfluidic chip offers a new tool for drug discovery. It could be used to find new treatments for liver disease and other conditions related to AGEs. However, it is important to note that while this method shows promise, more research is needed to fully understand its potential and limitations. The use of 3D cell models is a step forward in creating more accurate and reliable testing methods. But, it is also crucial to consider the ethical implications of using such models and ensure that they are used responsibly. The hunt for anti-aging compounds is ongoing, and this new method is a significant step forward. But, it is just one piece of the puzzle. A holistic approach that considers diet, lifestyle, and other factors is needed to truly combat aging and disease.
