Alkaloids are well-studied secondary metabolites, with recent preclinical studies evidencing that many of them exhibit anti-cancer, anti-depressant, anti-nociceptive, anti-inflammatory, anti-pyretic, anti-platelet, anti-oxidant, and anti-bacterial properties. Aconitum is a genus rich of diverse alkaloids. More than 450 alkaloids have been identified in a variety of species. Songorine is a C20 diterpenoid alkaloid and 12-keto analog of napelline, isolated from Aconitum soongaricum and was associated with a heterogeneous panel of biological functions. However, the bioactivity profile of this natural product has not been reviewed up to now. The present manuscript aims to summarize the most important biological activities associated with songorine administration in preclinical models. The most significant data found in the scientific literature were evaluated in order to summarize the potential clinical utility of songorine in a diverse spectrum of pathologies and conditions. Songorine and its derivatives have many pharmacological effects including anti-arrhythmic, anti-cardiac-fibrillation, excitation of synaptic transmission, anxiolytic effects, anti-nociceptive, anti-inflammatory, anti-arthritis effects, and a regenerative effect in a skin excision wound animal model. Despite its outstanding pharmacotherapeutic potential, songorine has never been tested in clinical trials. Therefore, further evaluation is required to better evaluate its clinical utility.
