activation of PPARs has a positive impact on cancer cell growth and viability in multiple preclinical tumor models, suggesting a new therapeutic potential for PPAR antagonists. In the present study, the benzothiazole amides 2a-g were synthesized and their activities on PPARs were investigated. Transactivation assay showed a moderate activity of the novel compounds as PPARα antagonists. Notably, in cellular
PPAR的激活减少对多种临床前肿瘤模型中的癌细胞生长和生存能力具有积极影响,这表明
PPAR拮抗剂具有新的治疗潜力。在本研究中,合成了
苯并噻唑酰胺2a-g并研究了其对
PPAR的活性。反式激活试验表明该新型化合物具有中等活性,可作为
PPARα拮抗剂。值得注意的是,在
细胞分析中,它们在过量表达
PPARα的胰腺癌,结肠直肠癌和副神经节瘤癌细胞中表现出细胞毒性。尤其是,化合物2b在两种副神经节瘤
细胞系中表现出最显着的活力抑制作用(大于90%),IC 50值在低微摩尔范围内。另外2b同一细胞中的集落形成能力明显受损。综上所述,这些结果表明化合物2b具有相关的抗增殖潜力,在副神经节瘤中是特别有效的,副神经节瘤是一种对化疗反应不良的罕见肿瘤。
