Novel substituted 6,7-dimethoxy-1-tetralones and 5,6-dimethoxy-1-indanones have been synthesized and evaluated for their cytotoxicity. Compounds with 3'-lipophilic. 3',5'-dilipophilic, or 3',5'-dilipophilic-4'-hydrophilic substituents on (E)-2-benzylidene moiety showed highly cytotoxic effects. The unique structure of 42 possibly matches the pharmacophore features for these cytotoxic compounds. (C) 2000 Elsevier Science Ltd. All rights reserved.

Synthesis of 4-phenyl-5,6-dihydrobenzo[h]quinazolines and their evaluation as growth inhibitors of carcinoma cells
The synthesis of various benzo[h]quinazoline analogs (4a–f, 6a–d, 8a and 8b) was accomplished through the reaction of chalcone with guanidine. The synthesized compounds (4a–f, 6a–d, 8a and 8b) were screened for their anticancer potential against different cancer cells viz MCF-7, DLD1, A549, DU145 & FaDu cell lines. Compounds 4a, 6a–d & 8b showed significant anticancer activity in these cancer cell
各种苯并[ h ]喹唑啉类似物(4a–f,6a–d,8a和8b)的合成是通过查耳酮与胍的反应完成的。合成的化合物(4A-F ,图6a-d ,图8a和图8b)筛选针对不同癌细胞其抗癌潜力即MCF-7,DLD1,A549,DU145&的FaDu细胞系。化合物4a,6a–d和8b在这些癌细胞系中表现出显着的抗癌活性,IC 50范围很大。值为1.5–12.99μM。对有希望的分子6d在24和48小时内的7μM(按IC 50值)进行的功能研究表明,它具有触发凋亡的抗癌活性。在微管蛋白聚合测定中,6d有效抑制微管蛋白聚合,IC 50为2.27μM。在对6d的计算机对接研究中发现,6d与雌激素受体以及秋水仙碱结合位点的β-折叠上的微管蛋白具有良好的亲和力。
