Novel purine-pyrazole hybrids combining thiazoles, thiazolidinones and rhodanines, were designed and tested as 15-LOX inhibitors, potential anticancer and antioxidant agents. All tested compounds were found to be potent 15-LOX inhibitors with IC50 ranging from 1.76 to 6.12 µM. The prepared compounds were evaluated in vitro against five cancer cell lines: A549 (lung), Caco-2 (colon), PC3 (prostate)
设计并结合了噻唑,噻唑烷酮和罗丹酮的新型嘌呤-吡唑杂化物作为15-LOX抑制剂,潜在的抗癌剂和抗氧化剂进行了测试。发现所有测试的化合物均为有效的15-LOX抑制剂,IC50为1.76至6.12 µM。体外针对五种癌细胞系评估了所制备的化合物:A549(肺),Caco-2(结肠),PC3(前列腺),MCF-7(乳腺癌)和HepG-2(肝)。化合物7b和8b对五种受试细胞系表现出广谱抗癌活性(IC50 = 18.5-95.39 µM)。同时,化合物7h对肺A549和结肠Caco-2细胞系表现出中等的抗癌活性。抗氧化剂筛选显示,发现IC50为0.93至14.43 µg / ml的6种化合物(5a,5b,6b,7b,7h和8b)是更有效的2种清除剂。2-二苯基-1-吡啶并肼基(DPPH)比抗坏血酸参考值高,IC50值为15.34 µg / ml。当评估化合物7b,7h和8b的抗氧化活性时,发现它们
