倍半萜内酯类化合物在抗肿瘤和抗炎治疗中有着广泛的应用。然而,这些物质的药理学机制尚不清楚。本研究以孤雌菊为例,探讨天然分子的抗肿瘤作用及其共同机制。结果表明,PTL通过ERK 2/NF-κB/Snail通路抑制了体外和体内EMT细胞的增殖和迁移。有趣的是,PTL的多个潜在靶点包含Gly-Leu-Ser/Lys-“共适应口袋”。这启发我们PTL的类比也可能与这些靶蛋白结合并发挥类似的功能。值得注意的是,共适应口袋的概念可能有助于增加药物研发的选择性。
Sesquiterpene lactones (SL) have a wide range of applications in anti-tumor and anti-inflammatory therapy. However, the pharmacological mechanism of such substances is not clear. In this study, parthenolide (PTL) was used as an example to explore the anti-tumor effect of natural molecules and their common mechanism. We showed that PTL inhibited the proliferation and migration by reverse EMT via the ERK2/NF-κB/Snail pathway in vivo and in vitro. Interestingly, Multiple potential targets of PTL contain a Gly-Leu-Ser/Lys-“co-adaptation pocket”. This inspiring us analogies of PTL may also bind to these target proteins and play a similar function. Significantly, the Concept of co-adaptation pocket may help to increase the selectivity of drug research and development.
