Identification
Common NameEmamectin B1b
ClassSmall Molecule
DescriptionEmamectin B1b is an exogenous compound that exists as a solid at room temperature. Its chemical formula is C48H73NO13. Emamectin B1b belongs to the carbohydrates and carbohydrate conjugates, a subclass of organooxygen compounds within the organic compounds. With an average molecular weight of 872.09 g/mol, Emamectin B1b is a heavy molecule. The compound interacts with eleven recorded protein targets. These include the Transient receptor potential cation channel subfamily A member 1 (TRPA1) and several gamma-aminobutyric acid receptor subunits, specifically GABRA1, GABRG1, GABRG2, and GABRR2. It is characterized by low solubility in water and extensive non-specific binding. Mechanistically, it opens GABA-insensitive chloride channels, which increases inward conductance and reduces membrane resistance.
