7,8-Dihydroxyflavone (7,8-DHF) is a synthetic flavonoid compound that has garnered interest in neuroscience research due to its ability to mimic brain-derived neurotrophic factor (BDNF) by selectively activating the TrkB receptor. Preclinical studies, primarily in rodent models, have shown that 7,8-DHF can promote neuroprotection, neurogenesis, and axonal regeneration, which are processes relevant to nerve damage and repair. For instance, several studies have demonstrated that systemic or local administration of 7,8-DHF can reduce neuronal loss and improve functional recovery in models of peripheral nerve injury, spinal cord injury, and neuropathic pain. These beneficial effects are attributed to enhanced TrkB signaling, leading to increased neuronal survival and synaptic plasticity. However, the current evidence is limited to animal models and in vitro studies; there are no published clinical trials in humans assessing the efficacy or safety of 7,8-DHF for treating nerve damage. As such, while the theoretical rationale and preclinical data are promising, there is insufficient evidence to justify its use in clinical practice. Additionally, 7,8-DHF is not found in significant concentrations in the diet or traditional medicine, and its use as a supplement is based on laboratory research, not historical precedent. Further research, including human trials, is needed before 7,8-DHF can be recommended for nerve damage.
