Peroxin 16 Activators

Peroxin 16 activators predominantly comprise compounds that engage with the peroxisome proliferator-activated receptor (PPAR) family. Activation of PPARs is a known trigger for the proliferation of peroxisomes within the cell, which is intimately linked to the increased expression and functionality of peroxins, including PEX16. This class of chemicals does not activate PEX16 directly but does so by promoting the biogenesis of the organelles that PEX16 is crucial for assembling and maintaining.

PPAR agonists like Pioglitazone, Bezafibrate, Fenofibrate, and Rosiglitazone act through the activation of PPAR-γ or PPAR-α receptors, which leads to the transcription of genes involved in peroxisome proliferation, thereby increasing the cellular demand for PEX16. Such agonists stimulate the nuclear receptors to bind to PPAR response elements (PPREs) within the promoter regions of target genes, enhancing the expression of a myriad of proteins, including those related to peroxisome biogenesis. Compounds such as WY-14643 and Tetradecylthioacetic Acid, which are synthetic and natural PPAR agonists respectively, also modulate peroxisomal gene expression, suggesting an increase in PEX16 activity through enhanced peroxisome formation and maintenance. GW7647 and L-165041, through their action on PPAR-α and PPAR-δ, demonstrate the ability to influence the cellular processes that demand PEX16 activity.
