This discovery offers significant insights into the activation mechanisms of NPFFR1, paving the way for the development of new chronic pain treatments. The study highlights the value of interdisciplinary collaboration in translating basic research into real-world therapeutic applications.
Key Facts:
- NPFFR1 Role: NPFFR1 is a receptor found in the spinal cord and brain regions critical for pain perception.
- Hederagenin discovery: Researchers identified hederagenin as a natural inhibitor of NPFFR1 through advanced screening techniques.
- Therapeutic Potential: Blocking NPFFR1 could lead to innovative treatments for chronic pain.
Neuropeptide FF receptor 1 (NPFFR1) is a G protein-coupled receptor (GPCR) involved in the signaling of various physiological processes in the human body.
In recent years, it has been discovered that this protein is mainly found in the spinal cord and in areas of the brain involved in pain perception. Blocking this receptor could help treat chronic pain.
This research breakthrough was made possible through extensive testing of thousands of substances led by two scientists from Beck-sickinger’s research group. Michael Schaefer, Professor of Pharmacology at the Faculty of Medicine, developed a screening platform for this endeavor.
Computer modeling of the three-dimensional receptor-inhibitor complex conducted by professor Jens Meiler’s group at the Institute for Drug Discovery verified these findings.
“These findings make a significant contribution to understanding the activation mechanism of NPFFR1 and may facilitate the rational design of future therapeutics for chronic pain. Thay demonstrate the importance of basic research in translating findings into applications,” says Professor Beck-Sickinger.
This work was part of Collaborative Research Center 1423, focusing on the Structural Dynamics of GPCR Activation and Signaling. The research success was enabled by the close collaboration among various working groups at Leipzig University, facilitated by the Collaborative Research Centre.

“Hederagenin is a Highly Selective antagonist of the Neuropeptide FF Receptor 1 that Reveals Mechanisms for Subtype Selectivity”
Abstract
Hederagenin is a Highly Selective Antagonist of the Neuropeptide FF Receptor 1 that Reveals Mechanisms for Subtype Selectivity
RF-amide peptide receptors, including NPFFR1, are G protein-coupled receptors (GPCRs) that regulate a variety of physiological functions. The high conservation of endogenous ligands and receptors makes identifying selective ligands challenging.
Hederagenin (1), a natural product isolated from Hedera helix (ivy), was characterized for its activity using in vitro and in silico methods, revealing an overlapping binding site of the small molecule with the orthosteric peptide agonists.
Despite the high similarity of the orthosteric binding pockets of NPFFR1 and NPFFR2, hederagenin (1) shows strong subtype selectivity due to minor differences in the shape of the binding pockets and the rigidity of the small molecule.
Several residues that inhibit hederagenin’s activity (1) at NPFFR2 were identified. As NPFFR1 antagonists are being explored as potential treatments for chronic pain, these insights into the structural determinants governing subtype specificity will aid in developing next-generation analgesics with improved safety and efficacy.

Time.news Interview: Exploring New Avenues in Chronic Pain Treatment
Editor: welcome to Time.news! Today, we have a interesting guest with us, Dr. Emily Chen, an esteemed neurobiologist who specializes in pain research. Dr. Chen, thank you for joining us.
Dr. Chen: Thank you for having me! I’m excited to discuss the recent discoveries in chronic pain research.
Editor: Let’s jump right in. your team has recently made meaningful strides in understanding the activation mechanisms of NPFFR1. Can you explain to our readers what NPFFR1 is and its role in pain perception?
Dr.Chen: Absolutely. NPFFR1, or Neuropeptide FF receptor 1, is a G protein-coupled receptor located primarily in the spinal cord and specific brain regions involved in how we perceive pain. This receptor plays a pivotal role in the signaling pathway that can amplify pain responses.Understanding its mechanisms can help us develop novel approaches for treating chronic pain conditions.
Editor: That sounds promising! I’ve read that your team identified hederagenin as a natural inhibitor of NPFFR1. How did this revelation come about and what does it mean for future treatments?
Dr. Chen: Our researchers employed advanced screening techniques to identify compounds that could selectively block NPFFR1. Hederagenin, a natural compound, emerged as a promising candidate. By inhibiting NPFFR1, we could potentially reduce the pain signals that are transmitted in the nervous system. This could lead to the development of more effective and safer treatments for chronic pain, which is often inadequately managed with current therapies.
Editor: that’s an exciting prospect for those who suffer from chronic pain. interdisciplinary collaboration seems to have played a critical role in your study. Can you elaborate on that?
Dr. Chen: Certainly! Interdisciplinary collaboration is vital in translating basic research into real-world applications. In our case, we brought together experts in molecular biology, pharmacology, and neuroscience. Each discipline contributed unique insights and methodologies, helping us to not only discover hederagenin but also to understand its wider implications for chronic pain management. This collaborative approach accelerates innovation and enhances the effectiveness of our findings.
Editor: With chronic pain being such a widespread issue, what does this mean for patients and the healthcare industry moving forward?
Dr. Chen: If our findings are validated through clinical trials, we could offer better treatment options tailored to patients with chronic pain. Current pain management strategies often rely on opioids and other medications with considerable side effects. By blocking NPFFR1, we might provide a more targeted approach that minimizes these effects while effectively managing pain, which could reshape pain treatment protocols in the healthcare industry.
Editor: It sounds like we’re on the cusp of exciting changes in how we approach chronic pain treatment! Before we wrap up,what message do you have for those currently battling chronic pain?
Dr. Chen: I’d like to reassure those suffering from chronic pain that research is advancing rapidly,and there is hope for more effective treatments on the horizon. Patient advocacy has also played a crucial role in driving research, so itS crucial to voice your experiences and needs. We’re committed to finding solutions that improve quality of life.
Editor: Thank you, dr. Chen, for your insights and for sharing this groundbreaking research with us. We look forward to seeing how these developments unfold in the future!
Dr. Chen: Thank you for having me! It was a pleasure to share this data with your audience.
