AMP-activated protein kinase: the current landscape for drug development

Area of Science:

• Biochemistry
• Metabolic Regulation
• Pharmacology

Background:

• AMP-activated protein kinase (AMPK) is a key regulator of cellular energy homeostasis.
• Various interventions like exercise and metformin enhance AMPK activity, conferring health benefits.
• Directly activating AMPK for therapeutic purposes has historically presented challenges.

Purpose of the Study:

• To review the current understanding of AMPK structure, regulation, and physiological roles.
• To highlight recent advancements in the identification and preclinical testing of direct AMPK activators.
• To discuss the potential therapeutic applications and safety considerations for AMPK activation.

Main Methods:

• Literature review of AMPK research.
• Analysis of preclinical data on direct AMPK activators.
• Discussion of ongoing clinical trials.

Main Results:

• Significant progress has been made in identifying direct AMPK activators.
• Several direct AMPK activators have shown promise in preclinical models.
• A limited number of these activators have progressed to clinical trials.

Conclusions:

• Despite challenges, direct AMPK activators are emerging as a therapeutic strategy.
• Further research is needed to determine the optimal disease indications for AMPK activation.
• Long-term safety and efficacy of therapeutic AMPK activation remain to be established.
