Finding New Medicines to Help Control Opioid Effects

Identification of small molecules that regulate endogenous opioid signaling by inhibiting angiotensin converting enzyme

NIH-funded research University of Minnesota · NIH-11140337

This research looks for new compounds that can affect how the brain's natural pain-relieving chemicals work, potentially helping with conditions like fentanyl addiction.

What this research studies

Our brains have natural chemicals, like enkephalins, that help manage pain and pleasure, similar to opioids. This project explores how a specific enzyme, Angiotensin-converting enzyme (ACE), breaks down one of these natural enkephalins in a brain area linked to reward. We are looking for new compounds that can stop ACE from breaking down this enkephalin, which could boost its natural effects. The goal is to find better ways to regulate these brain chemicals, potentially reducing the rewarding effects of powerful opioids like fentanyl.

Who could benefit from this research

Good fit: Patients who might benefit from future treatments developed from this research include those struggling with opioid use disorder or chronic pain.

Not a fit: Patients not currently affected by opioid use or related pain conditions would not directly benefit from this specific research.

Why it matters

Potential benefit: If successful, this work could lead to new medications that help reduce the rewarding effects of opioids, offering a novel approach to treating opioid addiction or managing pain.

How similar studies have performed: While existing ACE inhibitors are used for blood pressure, this research explores a novel application of ACE inhibition specifically for brain opioid signaling, which is a new area of focus.
