antinociceptive activities of 5-(3,4-dihydroxyphenyl)-3-hydroxy-1-(2-hydroxyphenyl)penta-2,4-dien-1-one (DHHPD), a novel synthetic curcuminoid analogue at 0.1, 0.3, 1 and 3 mg/kg (intraperitoneal), through chemical and thermal models of nociception. The effects of DHHPD on the vanilloid and glutamatergic systems were evaluated through the capsaicin- and glutamate-induced paw licking tests. Results showed that DHHPD

姜黄素具有镇痛、抗氧化和抗炎活性。我们评估了 5-(3,4-dihydroxyphenyl)-3-hydroxy-1-(2-hydroxyphenyl)penta-2,4-dien-1-one (DHHPD)(一种新型合成类
姜黄素类似物)的外周和中枢镇痛活性通过伤害感受的
化学和热模型,以 0.1、0.3、1 和 3 mg/kg(腹膜内)给药。DHHPD 对香草素和谷
氨酸能系统的影响通过

氨酸诱导的舔爪试验进行评估。结果表明,DHHPD 显着 (p < 0.05) 减弱了 0.8% 乙酸注射产生的扭体反应。此外,1 和 3 毫克/千克的 DHHPD 显着 (p < 0.05) 减少了每只小鼠在 2 阶段的两个阶段所花费的舔食时间。5%福尔马林试验,增加小鼠对电炉的反应潜伏期。然而,后者产生的作用并没有被非选择性阿片受体拮抗剂
纳洛酮逆转。尽管如此,DHHPD 以
