A new series of ortho-naphthoquinone analogs of β-lapachone were designed, synthesized and evaluated. The biological results indicated that most of our compounds were efficient substrates for NQO1. The new scaffold with water-soluble side chain resulted in greater solubility under acidic condition compared to β-lapachone. Thus avoiding the use of hydroxylpropyl β-cyclodextrin which would finally cause
设计、合成和评估了一系列新的β-拉帕酮邻萘醌类似物。生物学结果表明,我们的大多数化合物是 NQO1 的有效底物。与 β-lapachone 相比,具有水溶性侧链的新支架在酸性条件下具有更大的溶解度。从而避免使用羟丙基β-环糊精,后者最终会导致药物从血液中快速清除和溶血性贫血形式的剂量限制性毒性。该系列中最易溶解和最有前途的化合物是 2-((4-benzylpiperazin-1-yl)methyl)naphtho[ 2,1- d ]oxazole-4,5-dione ( 3k ),可抑制癌细胞 (NQO1-丰富的 A549 细胞系)生长,IC 50值为 4.6 ± 1.0 μmol·L-1。此外,化合物3k在 A549 肿瘤异种移植小鼠模型中具有与用 β-拉帕酮获得的活性相当的体内抗肿瘤活性。结果表明,这些邻萘醌可以作为进一步优化作为 NQO1 新型底物的有希望的线索。
