Colchicine, while compound 23 was the most active against HepG-2 as compared with Doxorubicin. We explored the SAR of 4H-benzo[h]chromenes with modification at the 2-,3- positions and 7H-benzo[h]chromeno[2,3-d]pyrimidine at 2,3-positions. The structure–activity relationship (SAR) study revealed that the antitumor activity on 4H-benzo[h]chromene and 7H-benzo[h]chromeno[2,3-d]pyrimidine derivatives were significantly
制备了一些4 H-苯并[ h ]色烯和7 H-苯并[ h ]色度[2,3- d ]嘧啶衍生物作为潜在的细胞毒剂。使用MTT比色法,与著名的抗癌标准药物长春碱,秋水仙碱和阿霉素比较,研究了合成化合物的体外细胞毒性活性。结果发现,化合物23,15,20,和21显示出针对三种肿瘤细胞系MCF-7,HCT,及HepG-2,用长春花碱和秋水仙碱相比最高的抗癌活性,而化合物23与阿霉素相比,其对HepG-2的活性最高。我们探索了在2-,3-位有修饰的4 H-苯并[ h ]色酮和在2,3-位有7 H-苯并[ h ] chromeno [ 2,3- d ]嘧啶的SAR 。结构-活性关系(SAR)研究表明,其对4 H-苯并[ h ]色烯和7 H-苯并[ h ]色素[2,3- d ]具有抗肿瘤活性]嘧啶衍生物受到2-,3-和2,3-位的取代基的亲脂性(疏水性或亲水性)的显着影响。这些化合物的结构基于光谱数据,IR,1
