RESUMEN
Proteasome controls the degradation of proteins closely related to life activities and plays a key role in the maintenance of protein homeostasis. Proteasome activities decrease with aging, followed by the overwhelming production of damaged proteins which far exceed the protein consumption. Accumulation of these proteins leads to various diseases including neurodegenerative diseases. Therefore, inducing toxic protein degradation is considered as a promising solution for the treatment of these diseases, while increasing the activity of proteasome is considered as an important strategy. However, the research in this field is still in the preliminary stage, and this review will focus on the discussion of the research progress of various small molecule proteasome activators, including research methods, pharmacological effects, structure-activity relationships and the existing problems.
