Sesquiterpene lactones are organic compounds derived mainly from plants that exhibit anti-inflammatory and antitumor activities being one of the key mechanism of action of NF-kB pathway and synthesis of cytokines such as IL-1 and TNF- α.
The overall objective of the present study was to evaluate the anti-inflammatory action of a sesquiterpene lactone diacethylpiptocarphol (DPC) from Vernonia scorpioides (Lam.) Pers. and parthenolide (PTH) in Balb-c mice with DSS-induced colitis.
The anti-inflammatory effects of Intraperitonial administration of DPC (5 mg/kg/day) were evaluated in Balb/c mice with DSS-induced colitis, and further the body weight measurement, TNF-α and TGF-β level was determined.
After intraperitoneal treatment for one week, DSS-induced colitis was significantly reduced in mice treated with either of both sesquiterpenes lactones, as witnessed by reduced cellular infiltration, tissue damage, TNF-α production, and enhanced production of TGF-β.
Sesquiterpene lactone DPC, isolated from Vernonia scorpioides showed anti-inflammatory activity, in this experimental model of colitis the sesquiterpene lactones DPC and PTH exhibit equal anti-inflammatory activity.
倍半萜内酯是主要从植物中提取的有机化合物,具有抗炎和抗肿瘤活性,是 NF-kB 通路和细胞因子如 IL-1 和 TNF-α合成的关键作用机制之一。
本研究的总体目标是评估来自 Vernonia scorpioides(Lam.)Pers 的倍半萜内酯二乙酰基派泊卡醇(DPC)和角鲨烯(PTH)在 DSS 诱导的结肠炎 Balb-c 小鼠中的抗炎作用。
在 DSS 诱导的结肠炎 Balb-c 小鼠中,通过腹腔内给予 DPC(5mg/kg/天)来评估其抗炎作用,并进一步测定 TNF-α和 TGF-β水平。
经过一周的腹腔内治疗,用两种倍半萜内酯处理的小鼠的 DSS 诱导的结肠炎明显减轻,表现为细胞浸润减少、组织损伤减轻、TNF-α产生减少和 TGF-β产生增加。
从 Vernonia scorpioides 中分离出的倍半萜内酯 DPC 具有抗炎活性,在这种结肠炎实验模型中,倍半萜内酯 DPC 和 PTH 表现出同等的抗炎活性。
