Pricing Availability Delivery Time Qty
Cat.No. 2242 - Octopamine hydrochloride | C8H11NO2.HCl | CAS No. 770-05-8
Description: Invertebrate biogenic amine: activates β3 adrenoceptors
Alternative Names: (±)-p-Octopamine, Epirenor, Norfen
Chemical Name: α-(Aminomethyl)-4-hydroxybenzenemethanol hydrochloride
Purity: ≥99% (HPLC)

Biological Activity

Invertebrate biogenic amine neurotransmitter, related to noradrenalin, that is an adrenoceptor agonist. Stimulates lipolysis in mammalian adipocytes via activation of β3 receptors. Has dual effect on glucose transport in adipocytes: inhibits transport via β3 receptor activation but stimulates transport when oxidized by MAO. Also activates human α2A receptors, inhibiting subsequent cAMP production.
