  <class>SmallMolecule</class>
  <description>Guanfacine is an organic compound with the chemical formula C9H9Cl2N3O and an average molecular weight of 246.09 g/mol. Guanfacine belongs to the halobenzenes, a subclass of benzene and substituted derivatives within the organic compounds.

The compound is recorded as being found in or released from 11 different sources. Within healthcare, pharmaceuticals, and veterinary products, it is used as an antihypertensive. In the category of food, food processing, and cookware, it is used for food preservation. It is also associated with household cleaning and consumer products, including perfumes within detergents and soaps, tobacco smoke filters, and non-electric simulated smoking devices. Furthermore, it is linked to electrical and electronic equipment, specifically antennas, conductors or conductive bodies characterised by the conductive materials, electrically stimulated smoking devices, electrodes, radio transmission systems, and one additional source. The recorded route of exposure for this compound is oral.

At the molecular level, guanfacine interacts with two recorded protein targets. It functions as an agonist or binder of the Alpha-2A adrenergic receptor (ADRA2A) and the Alpha-2B adrenergic receptor (ADRA2B).</description>
