synthetic derivative “C” showed stronger antineoplastic effects than the naturalparent “Q” may via the anti-inflammatory activities. Therefore, the newlysynthesized chromene derivative is more promising as a futureantitumorcandidate than the naturalparentmolecule “Quercetin.” Finally, our results encourage researchers to pay more attention to developing more novel natural-based derivatives that would
寻找新的有效抗癌药物非常重要。在这项研究中,制备了一种新合成且表征良好的色烯衍生物(2-氨基-4-苯基-4H-苯并(h)色烯-3-羧酸乙酯)“ C ”。进行了分子对接研究。与天然母体槲皮素“ Q ”相比的新化合物“ C ”,”作为一种众所周知的具有抗氧化和抗肿瘤活性的天然色烯衍生物,测试了它们对携带艾氏腹水癌 (EAC) 小鼠的抗肿瘤活性。两者都减少了腹水量,减少了可行的 EAC 细胞,并延长了携带 EAC 的小鼠的寿命。他们使肌钙蛋白、肌酸激酶-MB、乳酸脱氢酶和尿素水平正常化,使肝酶活性恢复正常,增加抗氧化水平,同时降低肿瘤坏死因子-α (TNF-α) 水平。相互比较,新的合成衍生物“ C ”显示出比天然母体“ Q ”更强的抗肿瘤作用”可能通过抗炎活动。因此,新合成的色烯衍生物比天然母体分子“槲皮素”更有希望作为未来的抗肿瘤候选者。最后,我们的研究结果鼓励研究人员更多地关注开发更多新颖

Synthesis and Biological Evaluation of Benzochromenopyrimidinones as Cholinesterase Inhibitors and Potent Antioxidant, Non-Hepatotoxic Agents for Alzheimer’s Disease
We report herein the straightforward two-step synthesis and biological assessment of novel racemic benzochromenopyrimidinones as non-hepatotoxic, acetylcholinesterase inhibitors with antioxidative properties. Among them, compound 3Bb displayed a mixed-type inhibition of human acetylcholinesterase (IC50 = 1.28 ± 0.03 μM), good antioxidant activity, and also proved to be non-hepatotoxic on human HepG2
