derivatization, three series of lathyrane diterpenoid derivatives were designed and synthesized based combination principles, including pyrazole, thiazole and furoxan moieties. Biological evaluation indicated that compound 23d exhibited excellently inhibitory activity on LPS-induced NO production in RAW264.7 cells (IC50 = 0.38 ± 0.18 μM). The preliminary structure–activity relationships (SARs) suggested
作为我们正在进行的二萜衍生化工作,基于组合原理设计和合成了三个系列的二萜衍生物,包括吡唑、噻唑和呋喃部分。生物学评估表明,化合物23d对 LPS 诱导的 RAW264.7 细胞中的 NO 产生具有极好的抑制活性(IC 50 = 0.38 ± 0.18 μM)。初步构效关系 (SARs) 表明,苯磺酰基取代的呋喃部分具有最强的提高 lathyrane 二萜类化合物抗炎活性的能力。此外,化合物23d显着降低 ROS 水平。其分子机制与抑制Nrf2/HO-1通路的转录激活有关。基于这些考虑,23d可能是一种很有前途的抗炎剂,值得进一步探索。
