The aim of this study was to design, synthesize and evaluate the potential analgesic and anti-inflammatory effects of 5-[1-(4-fluorphenyl)-1H-1,2,3-triazol-4-yl]-1H-tetrazole—(LQFM-096: a new triazole compound) as well as to elucidate its possible mechanisms of action. The oral administration of LQFM-096 (10, 20 or 40 mg/kg) decreased the number of writhing in mice. At the dose of 20 mg/kg, LQFM-096 reduced the licking time at both neurogenic and inflammatory phases of the formalin test. Pretreatment with naloxone (3 mg/kg) and glibenclamide (3 mg/kg) attenuated the antinociceptive effect of LQFM-096 in the first phase of the formalin test. At the dose of 20 mg/kg, LQFM-096 also decreased the licking time in the acidified saline-induced and capsaicin-induced nociception. This effect was blocked by naloxone (3 mg/kg) pretreatment prior to the administration of LQFM-096. In addition, LQFM-096 inhibited hyperalgesia induced by carrageenan and PGE2. Naloxone (3 mg/kg) attenuated the effect of LQFM-096 through disinhibition of PGE2-induced hyperalgesia. The anti-inflammatory effect of LQFM-096 was demonstrated in carrageenan-induced oedema or pleurisy as well as CFA-induced arthritis. The hyperalgesia and cellular migration in CFA-induced arthritis were reduced significantly. Altogether, these findings suggest antinociceptive effect of LQFM-096 and implicate the modulation of ASICs/TRPV1 channels by opioid/KATP pathway. The anti-inflammatory effect of LQFM-096 was mediated by a reduction in oedema, leukocytes migration, TNF-α, PGE2 levels and myeloperoxidase activity.

一种新的三唑衍生物的抗伤害感受和抗炎作用的机制:5- [1-(4-氟苯基)-1H-1,2,3-三唑4-基] -1H-四唑(LQFM-096) 。

这项研究的目的是设计,合成和评估5- [1-(4-氟苯基)-1H-1,2,3-三唑-4-基] -1H-四唑的潜在止痛和抗炎作用(LQFM-096:一种新的三唑化合物),并阐明其可能的作用机理。口服LQFM-096(10、20或40 mg / kg)减少了小鼠的扭体次数。在20 mg / kg的剂量下,LQFM-096减少了福尔马林测试在神经发生阶段和炎症阶段的舔the时间。在福尔马林测试的第一阶段,用纳洛酮(3 mg / kg)和格列苯脲(3 mg / kg)进行预处理可减弱LQFM-096的抗伤害感受作用。在20 mg / kg的剂量下,LQFM-096还减少了酸化盐水诱导和辣椒素诱导的伤害感受的舔the时间。在施用LQFM-096之前,可通过纳洛酮(3 mg / kg)预处理阻断这种作用。此外,LQFM-096抑制角叉菜胶和PGE2引起的痛觉过敏。纳洛酮(3 mg / kg)通过抑制PGE2引起的痛觉过敏来减弱LQFM-096的作用。LQFM-096的抗炎作用在角叉菜胶诱发的水肿或胸膜炎以及CFA诱发的关节炎中得到证明。CFA诱发的关节炎的痛觉过敏和细胞迁移明显减少。总而言之,这些发现暗示了LQFM-096的抗伤害感受作用,并暗示了阿片/ KATP途径对ASICs / TRPV1通道的调节。LQFM-096的抗炎作用是通过减少水肿,白细胞迁移,TNF-α,PGE介导的 LQFM-096抑制角叉菜胶和PGE2引起的痛觉过敏。纳洛酮(3 mg / kg)通过抑制PGE2引起的痛觉过敏来减弱LQFM-096的作用。LQFM-096的抗炎作用在角叉菜胶诱发的水肿或胸膜炎以及CFA诱发的关节炎中得到证明。CFA诱发的关节炎的痛觉过敏和细胞迁移明显减少。总而言之,这些发现暗示了LQFM-096的抗伤害感受作用,并暗示了阿片/ KATP途径对ASICs / TRPV1通道的调节。LQFM-096的抗炎作用是通过减少水肿,白细胞迁移,TNF-α,PGE介导的 LQFM-096抑制角叉菜胶和PGE2引起的痛觉过敏。纳洛酮(3 mg / kg)通过抑制PGE2引起的痛觉过敏减弱了LQFM-096的作用。LQFM-096的抗炎作用在角叉菜胶诱发的水肿或胸膜炎以及CFA诱发的关节炎中得到证明。CFA诱发的关节炎的痛觉过敏和细胞迁移明显减少。总而言之,这些发现暗示了LQFM-096的抗伤害感受作用,并暗示了阿片/ KATP途径对ASICs / TRPV1通道的调节。LQFM-096的抗炎作用是通过减少水肿,白细胞迁移,TNF-α,PGE介导的 LQFM-096的抗炎作用在角叉菜胶诱发的水肿或胸膜炎以及CFA诱发的关节炎中得到证明。CFA诱发的关节炎的痛觉过敏和细胞迁移明显减少。总而言之,这些发现暗示了LQFM-096的抗伤害感受作用,并暗示了阿片/ KATP途径对ASICs / TRPV1通道的调节。LQFM-096的抗炎作用是通过减少水肿,白细胞迁移,TNF-α,PGE介导的 LQFM-096的抗炎作用在角叉菜胶诱发的水肿或胸膜炎以及CFA诱发的关节炎中得到证明。CFA诱发的关节炎的痛觉过敏和细胞迁移明显减少。总而言之,这些发现暗示了LQFM-096的抗伤害感受作用,并暗示了阿片/ KATP途径对ASICs / TRPV1通道的调节。LQFM-096的抗炎作用是通过减少水肿,白细胞迁移,TNF-α,PGE介导的2水平和髓过氧化物酶活性。
