promotes heme catabolism exercising cytoprotective roles in normal and cancer cells. Herein, we report the design, synthesis, molecular modeling, and biological evaluation of novel HO-1 inhibitors. Specifically, an amide linker in the central spacer and an imidazole were fixed, and the hydrophobic moiety required by the pharmacophore was largely modified. In many tumors, overexpression of HO-1 correlates
血红素加氧酶-1 (HO-1) 促进血红素分解代谢,在正常细胞和癌细胞中发挥细胞保护作用。在此,我们报告了新型 HO-1 抑制剂的设计、合成、分子建模和生物学评价。具体来说,固定了中心间隔基中的酰胺连接体和咪唑,并对药效团所需的疏水部分进行了很大程度的修饰。在许多肿瘤中,HO-1 的过度表达与不良预后和化疗耐药相关,表明抑制 HO-1 作为一种可能的抗肿瘤策略。因此,化合物7i和7l – p因其对抗 HO-1 的效力而出现,并研究了它们对前列腺 (DU145)、肺癌 (A549) 和胶质母细胞瘤 (U87MG、A172) 癌细胞的抗癌活性。所选化合物对 U87MG 细胞表现出最佳活性。进一步研究了化合物7l的细胞内酶HO-1活性、表达水平以及对细胞侵袭和血管内皮生长因子(VEGF)胞外释放的影响。获得的数据表明7l可以通过调节HO-1表达来降低细胞侵袭性。
