ligands is a novel strategy for the development of anticancer therapies. A series of 16 compounds based on the structure of 3-(pyridin-3-yl)-5-(thiophen-3-yl)-1,2,4-oxadiazole (natural compound) with antitumour potential were designed and synthesised. The cytotoxicity and PPAR agonist activity of these synthetic 1,2,4-oxadiazoles were evaluated in the A-498 and DU 145 tumour cell lines. Preliminary biological
通过天然配体调节 PPAR-α 是开发抗癌疗法的新策略。基于3-(吡啶-3-基)-5-(噻吩-3-基)-1,2,4-恶二唑(天然化合物)结构,设计并合成了一系列具有抗肿瘤潜力的16种化合物。在 A-498 和 DU 145 肿瘤细胞系中评估了这些合成 1,2,4-恶二唑的细胞毒性和 PPAR 激动剂活性。初步生物学评估表明,大多数这些合成 1,2,4-恶二唑的细胞毒性(磺胺罗丹明 B 测定)低于阳性对照 WY-14643。关于 PPAR-α 调节,化合物16的活性最强,EC 50 = 0.23–0.83 μM (PPAR-α)。此外,化合物16与天然化合物具有相似的活性 (EC 50 = 0.18–0.77 μM),并且在 RPTEC 和 WPMY-1 细胞系(非肿瘤细胞)中的毒性 (CC 50 = 81.66–92.67 μM) 低于天然化合物。天然化合物。通过观察化学结构和活性之间的联
