3-Methoxytyramine hydrochloride is an inactive metabolite of dopamine which can activate trace amine associated receptor 1 (TAAR1).
The intensity of the fluorescence developed is in a linear relation to the amount of 3-Methoxytyramine hydrochloride presented in the sample up to at least 1 μg. When a high concentration of dopamine is present in the reaction mixture, there is some reduction in the fluorescence derived from 3-Methoxytyramine hydrochloride[1].
The extracellular DA metabolite 3-Methoxytyramine hydrochloride (3-MT) induces significant behavioral activation in DDD mice. This activity however, is mostly presented as a set of disorganized abnormal movements that includes tremor, head bobbing, straub tail, grooming and abnormal orofacial movements rather than normal forward activity. No effect is observed when 3-Methoxytyramine hydrochloride is infused at doses below 9 µg, at 9 µg and higher doses 3-Methoxytyramine hydrochloride dose-dependently causes transient behavioral activation with a complex set of behaviors. In particular, transient hyperactivity and stereotypy, sniffing, grooming, rearing and mild abnormal involuntary movements (AIMs) at the level of limbs is observed after infusion of 9 µg of 3-Methoxytyramine hydrochloride. Similar behaviors are also observed after 18 µg of 3-Methoxytyramine hydrochloride with the additional appearance of tremor as well as oral and whole body AIMs[1].

Cell experiment: |
The rats are killed by cervical dislocation and the brains are removed and placed on an ice-cooled glass plate. The corpora striata are dissected out and homogenized immediately or stored at -17°C until analyzed. For the estimation of 3-Methoxytyramine hydrochloride 1 mL of the neutralized perchloric acid solution is placed in a glass test tube. One millilitre of a solution of potassium ferricyanide (20 μg/mL) in concentrated ammonium hydroxide is added. After 2 min 0 to 1 mL of a solution of cysteine (1 mg/mL) is added and mixed. The fluorescence of the resulting solution is measured in a spectrophotofluorometer fitted with an interference filter in the fluorescence light path. A blank determination is made by reversing the order of the addition of the ferricyanide-ammonia solution and the solution of cysteine. Authentic 3-Methoxytyramine hydrochloride is also added to a portion of the neutralized eluate and the fluorescence developed to check for quenching[1]. |

Animal experiment: |
To assess effects of 3-Methoxytyramine hydrochloride (3-MT) in normal and TAAR1-KO mice, the animals are placed in the locomotor activity chamber and 30 min later various doses of 3-Methoxytyramine hydrochloride are administered i.c.v.. To perform i.c.v. administration in this paradigm, habituated mice are removed from the experimental chamber, briefly restrained, i.c.v. injection cannula is placed into the previously implanted (one week before) guide cannula and infusion of 3-Methoxytyramine hydrochloride or vehicle is performed for 4 minutes when animal is freely moving in a home cage. After infusion, animals are put back into experimental chamber and behavior is monitored for 90 min after administration[1]. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
