JP-1302 is an antagonist of α2-adrenergic receptors (α2-ARs) that is selective for α2C-ARs over α2A- and α2B-ARs (Kis = 28, 3,150, and 1,470 nM, respectively). It reduces immobility time in the forced swim test in mice when administered at doses of 1, 3, and 10 µmol/kg. JP-1302 (5 mg/kg) reverses phencyclidine-induced decreases in prepulse inhibition of the acoustic startle response in rats. It dose-dependently reduces haloperidol-induced bradykinesia and catalepsy in mice. JP-1302 (0.3 mg/kg) also increases systolic blood pressure in rats.

Further analysis of the inhibition by agmatine on the cardiac sympathetic outflow: Role of the α2-adrenoceptor subtypes
Eur J Pharmacol 2017 Jun 15;805:75-83.PMID:28315344DOI:10.1016/j.ejphar.2017.03.009.
This study has investigated the role of the α2-adrenoceptor subtypes involved in the inhibition of the cardiac sympathetic outflow induced by intravenous (i.v) infusions of agmatine. Therefore, we analysed the effect of an i.v. bolus injections of the selective antagonists BRL 44408 (300μg/kg; α2A), imiloxan (3000μg/kg; α2B), and JP-1302 (300μg/kg; α2C) given separately, and their combinations: BRL 44408 plus Imiloxan, JP 1302 plus imiloxan, BRL 44408 plus JP-1302, BRL 44408 plus imiloxan plus JP-1302 on the cardiac sympatho-inhibition of agmatine. Also, the effect of the combination BRL 44408 plus JP-1302 plus AGN 192403 (3000μg/kg; I1 antagonist) was evaluated. In this way, i.v. infusions of 1000μg/kg min of agmatine, but not 300, inhibited the tachycardic response induced by electrical stimulation. Furthermore, the antagonists used or their combinations had no effect on the electrically-induced tachycardic response. On the other hand, the inhibitory response of agmatine was: (1) partially antagonized by BRL 44408 or JP-1302 given separately, a similar response was observed when we administered their combination with imiloxan, but not by imiloxan alone, (2) antagonized in greater magnitude by the combination BRL 44408 plus JP-1302 or the combination BRL 44408 plus imiloxan plus JP-1302, and (3) abolished by the combination BRL 44408 plus JP-1302 plus AGN 192403. Taken together, these results demonstrate that the α2A- and α2C-adrenoceptor subtypes and I1-imidazoline receptors are involved in the inhibition of the cardiac sympathetic outflow induced by agmatine.
α2A-adrenoceptors, but not nitric oxide, mediate the peripheral cardiac sympatho-inhibition of moxonidine
Eur J Pharmacol 2016 Jul 5;782:35-43.PMID:27112661DOI:10.1016/j.ejphar.2016.04.043.
Moxonidine centrally inhibits the sympathetic activity through the I1-imidazoline receptor and nitric oxide. In addition, inhibits the peripheral cardiac sympathetic outflow by α2-adrenoceptors/I1-imidazoline receptors, although the role of α2-adrenoceptor subtypes or nitric oxide in the cardiac sympatho-inhibition induced by moxonidine are unknown. Therefore, the cardiac sympatho-inhibition induced by moxonidine (10μg/kgmin) was evaluated before and after of the treatment with the following antagonists/inhibitor: (1) BRL 44408, (300μg/kg, α2A), imiloxan, (3000μg/kg, α2B), and JP-1302, (300μg/kg, α2C), in animals pretreated with AGN 192403 (3000μg/kg, I1 antagonist); (2) N(ω)-nitro-l-arginine methyl ester (l-NAME; 34, 100, and 340μg/kgmin); and (3) the combinations of the highest dose of l-NAME plus AGN 192403 or BRL 44408. Additionally, the expression of the neuronal (nNOS) and inducible (iNOS) nitric oxide synthase in the stellate ganglion was determined after treatment with moxonidine (i.p. 0.56mg/kg daily, during one week). The cardiac sympatho-inhibition of 10μg/kgmin moxonidine was: (1) unaffected by imiloxan and JP-1302, under pretreatment with AGN 192403, or l-NAME (34, 100 and 340μg/kgmin) given alone; (2) partially antagonized by the combination of 340 μg/kgmin l-NAME plus BRL 44408; and (3) abolished by BRL 44408 under treatment with AGN 192403. Furthermore, moxonidine did not modify the nNOS or iNOS protein expression in the stellate ganglion, the main source of postganglionic sympathetic neurons innervating the heart. In conclusion, our results suggest that the peripheral cardiac sympatho-inhibition induced by moxonidine is mediated by α2A-adrenoceptor subtype but not by nitric oxide.
