REDD-2 Activators

REDD-2 activators are chemicals that either directly activate the DNA damage-inducible transcript 4-like protein or interact with cellular pathways to modulate its activity. These activators are understood through the lens of cellular metabolism and energy regulation. The activation of REDD-2 is closely tied to the cellular energy state, and thus compounds that are involved in the modulation of energy sensing, and stress response pathways naturally intersect with the regulation of REDD-2 activity. Among these, AMPK is a critical sensor and regulator of cellular energy homeostasis, and several compounds that activate REDD-2 do so by first activating AMPK. This provides a molecular link between the presence of these compounds and the subsequent activation of REDD-2.

The biochemical pathways involved with these activators are complex and interwoven. The compounds that indirectly influence REDD-2 do so by modulating the activity of AMPK or other related sensors and mediators of cellular energy and nutrient status, such as mTOR and SIRT1. These activators work by initiating a chain of intracellular events or by influencing the expression of genes that control energy balance and stress response. Such compounds do not work in isolation but are part of a broader cellular signaling context, which ensures that the activation of REDD-2 is a regulated process, integrated with the cell's overall function and state.
