(15) showed significant cytotoxicities. The most effective compound was 15, which showed high cytotoxic activity with an IC50 value lower than 1 μg/ml, and no selectivity on the tumor cells evaluated. Substituents at C(4) of ring B were found to be essential for cytotoxicity. In addition, it was also demonstrated that some of these chalcones are moderate inhibitors of cathepsin K and have no activity
通过 ClaisenSchmidt 缩合制备了一系列查耳酮衍生物 1-15,并评估了它们对肿瘤细胞系以及对蛋白水解酶(如组织蛋白酶 B 和 K)的细胞毒性。合成的化合物中,(E)-3-( 3,4-二甲氧基苯基)-1-苯基丙-2-en-1-one (12), (E)-3-(4-氯苯基)-1-苯基丙-2-en-1-one (13), ( E)-3-(4-甲氧基苯基)-1-苯基丙-2-en-1-one (14)和(E)-3-(4-硝基苯基)-1-苯基丙-2-en-1-one (15) 显示出显着的细胞毒性。最有效的化合物是 15,它显示出高细胞毒活性,IC50 值低于 1 μg/ml,并且对评估的肿瘤细胞没有选择性。发现环 B 的 C(4) 处的取代基对细胞毒性至关重要。此外,
