摘要：Based on the principles of the bioisosterism, combination of the active substructures of selective estrogen receptor modulators which are currently therapeutic agents available for the prevention and treatment of various estrogen dependent diseases, and structural optimization, a novel series of 2-aroyl-3-aryl-6,7-dihydro-5H-furo[3,2-g]- chromen derivatives was designed as potent selective estrogen receptor modulators via molecular docking. The target compounds have been synthesized, and characterized by 1R, proton NMR, ESI-MS, elemental analysis and evaluated for their antitumor activity against human osteosarcoma U2OS-EGFP-4FI2G cell line. Some target compounds showed good inhibition effects on U2OS-EGFP-4F12G cell line and the preliminary structure-activity relationships were discussed.

摘要：目的设计合成5H-呋喃并[3,2-g]色烯类化合物,并测定其体外抗肿瘤活性。方法以2′,4′-二羟基苯乙酮为原料,经缩合、催化氢化和Fries重排等反应合成目标化合物。采用人骨肉瘤细胞U2OS-EGFP-4A12G对目标化合物的体外抗肿瘤活性进行初步评价。结果与结论合成了10个未见文献报道的5H-呋喃并[3,2-g]色烯类化合物,其结构经红外光谱、质谱、核磁共振氢谱确证。化合物7a、7e和7h对人骨肉瘤细胞U2OS-EGFP-4A12G的抑制活性较强,其IC50值分别为16.53、7.74、13.27μmol.L-1。5H-呋喃并[3,2-g]色烯类化合物是一类具有新型骨架结构的抗肿瘤化合物,值得进一步研究。

摘要：本文以2-巯基噻吩为原料,经6步反应合成了5个1,4-二氢噻吩并[3',2':5,6]噻喃并[4,3-c]吡唑-3-羧酸衍生物,并采用人乳腺癌细胞MCF-7对目标化合物的抗肿瘤活性进行初步评价。所合成化合物在100μM浓度下均有一定的抑制MCF-7活性。
