RWJ52353 hydrochloride 

RWJ-52353 hydrochloride is an orally potent, highly selective α2D adrenergic receptor agonist (Ki: 1.5 nM) with potential analgesic effects. RWJ-52353 hydrochloride demonstrated analgesic activity in abdominal tests in rats and mice, and improved agitation in mice in the hot plate test and tail flick test. RWJ-52353 hydrochloride also regulates the organic cation transporter (OCT) subtype, inhibiting rOCT1 and rOCT2 with IC₅₀s of 100 μM and 20 μM respectively; it also activates rOCT3, affecting [3H]-1- in cells. Methyl-4-phenylpyridinium ([3H]MPP) transport^[1][2].

Ki: 1.5 nM (α_2D AR), 254 nM (α_2A AR), 621 nM (α_2B AR), 443 nM (α₁ AR)^[1]
IC50: 100 μM (rOCT1), 20 μM (rOCT2)^[2]

RWJ-52353 (30 mg/kg; po; 单剂量) hydrochloride 在诱导引起的小鼠腹部疼痛模型具有抑制作用，抑制率达到 100%^[1]。
RWJ-52353 在诱导引起的大鼠和小鼠的腹部疼痛模型中的 ED50s 分别为 15.1 mg/kg (po) 和 11.6 mg/kg (po)^[1]。
RWJ-52353 还能够减轻小鼠在热板实验 (48°C) 和甩尾实验中的痛苦程度，ED50s 分别为 25.9 mg/kg (po) 和 100.2 mg/kg (po)^[1]。
