Complanatuside Ameliorates Renal Injury and Fibrosis in Chronic Kidney Disease by Inhibiting Tubular Cell Apoptosis via Activation of KLK1/BDKRB2.

Key takeaways

Complanatuside is the main active compound in an astragalus seed extract used in Chinese medicine. In this lab work it reduced kidney damage and scarring by keeping tubule cells, the cells that line the kidney's filtering tubes, from dying off. The effect ran through a specific cell signal pathway called KLK1/BDKRB2. This was done in animals and cells, not in people, so it is an early finding only.
