VDAC1 Inhibitors

The Voltage-Dependent Anion Channel 1 (VDAC1) is an integral membrane protein found predominantly in the outer mitochondrial membrane. It plays a pivotal role in the regulation of mitochondrial function and is involved in various cellular processes including metabolism, ion homeostasis, and the release of mitochondrial molecules during apoptosis. Structurally, VDAC1 forms a barrel-shaped channel that allows the passage of ions and metabolites, such as ATP, ADP, and pyruvate, between the cytosol and the mitochondrial intermembrane space. The channel's activity is regulated by voltage across the mitochondrial membrane, and by interactions with other proteins and small molecules.

VDAC1 inhibitors are a class of compounds that specifically target the VDAC1 channel, modulating its activity. These inhibitors can act through various mechanisms. Some may directly bind to the channel, inducing conformational changes that either increase or decrease its conductance. Others might interfere with the interactions between VDAC1 and its regulatory proteins or small molecules, thereby indirectly affecting channel function. Additionally, certain inhibitors might target the expression levels or post-translational modifications of VDAC1, leading to changes in its abundance or activity.
