Hsp90 is a potential target for the treatment of cancer. Curcumin is a natural product used to prevent and treat
cancer. 4-(4-Hydroxy-3-methoxybenzyl) curcumin (C086), a 4-arylmethyl curcumin analogue, showed lead-like properties.
Western blot analyses and molecular docking study supported C086 as an Hsp90 inhibitor. Subsequently, C086 analogues
were designed, synthesized and evaluated. These compounds showed increased antiproliferative activity against
SKBr3 and MCF-7 breast cancer cells. The most promising compounds 7 and 10 (IC50=1.66µM and 0.509µM) were 5-
fold and 17-fold better than C086 (IC50=8.55µM) against SkBr3 cell, respectively. Her2 degradation and Hsp70 induction
were observed upon administration of selected 4-arylmethyl curcumin analgues, suggesting that these compounds exerted
their activity through Hsp90 inhibition.
Hsp90 是治疗癌症的潜在靶点。姜黄素是一种用于预防和治疗癌症的天然产物。4-(4-羟基-3-甲氧基苄基) 姜黄素 (C086) 是一种 4-芳基甲基姜黄素类似物,显示出领先的特性。西方印迹分析和分子对接研究支持 C086 作为 Hsp90 抑制剂。随后,对 C086 类似物进行了设计、合成和评估。这些化合物对 SKBr3 和 MCF-7 乳腺癌细胞表现出增强的抗增殖活性。最有前景的化合物 7 和 10 (IC50 分别为 1.66µM 和 0.509µM)在针对 SkBr3 细胞时分别比 C086(IC50=8.55µM)更有效,效果提高了 5 倍和 17 倍。观察到在给药选定的 4-芳基甲基姜黄素类似物后 Her2 降解和 Hsp70 诱导,这表明这些化合物通过抑制 Hsp90 发挥了它们的活性。
