摘要

Background

Voltage-gated sodium channels (VGSCs) are essential for generating and propagating action potentials in excitable cells. They are considered to be promising potential targets for analgesics acting on nociceptive neurons. However, the translation of animal model analgesic data to humans makes VGSCs-targeting analgesic drug development challenging. Starting with human experience to find analgesics can reduce such failures. Traditional Chinese medicine (TCM), a traditional medical system, has rich human experience of analgesics, which means many Traditional Chinese Medicine Herbs (TCMH) are worth exploring for analgesic drug development. However, studies of the analgesic mechanisms of TCMH need to be conducted at the cellular and molecular level for a VGSC perspective.

Purpose

In this review, we provide an overview of the TCMH analgesics and molecules from TCMH, that act on VGSCs, especially subtype Nav1.3, Nav1.7, and Nav1.8, along with a brief discussion on pharmaceutical potential for pain management. We also provide references for Chinese medicine to study pain relief mechanisms at the molecular level of sodium ion channels.

Methods

Using Web of Science, the PubMed, and China National Knowledge Infrastructure databases, we conducted a comprehensive search of literature and data on TCMH and VGSCs published before October 2024.

Conclusion

While Navl.3, Navl.7, Navl.8 and Navl.9 are involved in the development and maintenance of pain, Navl.8 can be studied as a potential drug target. The traditional Chinese medicine herbs involved sodium ion channels are primarily categorized into seven types, including 30 well-defined natural ingredients and 33 TCMH extracts. Studying the interactions between the components of TCMH is an important prerequisite for further exploration of how a specific analgesic TCM or TCM formula modulates ion channels or whether it binds to specific sites on these channels.
