Molecular Mechanism of Mad Honey: Grayanotoxins and Site 2 Sodium Channel Pharmacology
Voltage-gated sodium channels (VGSCs) are the primary molecular targets of grayanotoxins. Understanding grayanotoxin pharmacology requires a foundational understanding of VGSC structure and gating. VGSCs are large integral membrane proteins — the α subunit, which contains the ion-conducting pore and the voltage-sensing machinery, is approximately 260 kDa and consists of four homologous domains (I–IV), each with […]
The Mad Honey Toxidrome: A Systems-Level Look at Cardiovascular and Neurological Effects
The physiological impact of mad honey is not confined to a single organ system. Grayanotoxins, by virtue of their action on voltage-gated sodium channels expressed across multiple tissue types, produce a constellation of effects spanning the cardiovascular system, the autonomic nervous system, the peripheral sensory nervous system, and the gastrointestinal tract. Understanding each system’s contribution […]
Grayanotoxins: Chemistry, Structure, and the Toxic Legacy of Ericaceae Plants
Grayanotoxins are a class of diterpenoid polyols — naturally occurring organic compounds characterised by a tetracyclic diterpene carbon skeleton bearing multiple hydroxyl groups. They belong to the broader family of grayanoid diterpenoids found exclusively within the plant family Ericaceae, which includes rhododendrons, azaleas, pieris, leucothoe, and related genera. The defining structural feature of grayanotoxins is […]
