17-Hydroxyventuricidin A (CAS 113204-43-6)

17-Hydroxyventuricidin A is a potent antifungal compound belonging to the family of macrolide antibiotics, known for its specific inhibition of mitochondrial ATP synthase. The mechanism of action involves binding to the F0 subunit of ATP synthase, effectively blocking proton translocation through the enzyme complex. This inhibition disrupts the proton gradient across the mitochondrial membrane, essential for ATP synthesis. As a result, cellular energy production is halted, leading to cell death in susceptible fungi and other eukaryotic cells dependent on oxidative phosphorylation for energy. In research, 17-Hydroxyventuricidin A is extensively utilized to study mitochondrial function and bioenergetics. Its ability to inhibit ATP synthase makes it a valuable tool for investigating the role of mitochondria in cellular metabolism, apoptosis, and the generation of reactive oxygen species (ROS). Researchers employ this compound to explore how disruptions in ATP production affect various cellular processes, providing insights into mitochondrial regulation and the interplay between energy metabolism and cell survival mechanisms. Additionally, 17-Hydroxyventuricidin A is used in studies focusing on the mechanisms of antifungal resistance and the identification of potential targets for novel antifungal agents. By understanding how this compound interacts with mitochondrial ATP synthase, researchers can gain insights into the structural and functional aspects of this critical enzyme, facilitating the development of new strategies to combat fungal infections. These applications underscore the importance of 17-Hydroxyventuricidin A in advancing the field of mitochondrial biology and energy metabolism.
