Naloxone (hydrochloride) is a pure opioid receptor antagonist [1]. Naloxone can rapidly reverse opioid-induced symptoms such as respiratory depression and sedation [2]. Naloxone is widely used in emergency treatment for opioid overdose, particularly to treat respiratory failure and restore spontaneous breathing [3-4].
In MDAMB231 cells, Naloxone (1-100μM; 48h) inhibits the proliferation and enhances the apoptosis of cells [5]. In KF cells, Naloxone (120μM; 72h) inhibits the proliferation of cells [6].
In MCF-7 cells xenograft tumor mice model, Tumor growth was significantly inhibited in mice treated with Naloxone (0.36mg/kg, 0.7mg/kg; ip; 4weeks) [7]. In C57BL/6J mice, Naloxone (3mg/kg; ip; single injection) reverses the respiratory and analgesic effects of opioid agonists and induces withdrawal [8].

Naloxone (hydrochloride)是一种纯阿片受体拮抗剂 [1]。Naloxone可以快速逆转阿片类药物引起的呼吸抑制和镇静等症状 [2]。Naloxone广泛用于阿片类药物过量紧急治疗,尤其用于治疗呼吸衰竭和恢复自主呼吸 [3-4]。
在MDAMB231细胞中,Naloxone(1-100μM;48h)抑制细胞增殖并促进细胞凋亡 [5]。在KF细胞中,Naloxone(120μM;72h)抑制细胞增殖 [6]。
在MCF-7细胞异种移植瘤小鼠模型中,Naloxone(0.36mg/kg,0.7mg/kg; ip; 4weeks)治疗小鼠的肿瘤生长受到显著抑制 [7]。在C57BL/6J小鼠中,Naloxone(3mg/kg;ip;单次注射)可逆转阿片类激动剂的呼吸和镇痛作用,并诱导戒断反应 [8]。
