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：长链末端环氧化物(LCTE)由于大位阻侧基的存在,难以高选择性地与二氧化碳(CO_(2))共聚并得到高碳酸酯单元含量的聚合物.本研究通过在卟啉meso苯环不同位置引入大位阻有机碱1,5,7-三叠氮双环[4.4.0]癸-5-烯(TBD),设计了一系列双功能卟啉铝催化剂,旨在调控TBD基团与铝中心的空间协同作用.其中TBD连接在meso苯环间位上的催化剂m-4展现出最佳的催化效果,可高选择性(99%)催化1,2-环氧丁烷或1,2-环氧己烷与CO_(2)完全交替共聚,制备得到分子量大于32 kg/mol的聚碳酸酯.通过原位红外光谱对反应进行动力学研究证明该催化剂分子内协同的催化特征.本文工作探究了双功能催化剂分子内催化位点的空间分布与所产生协同作用的关系,为LCTE/CO_(2)高效交替共聚合成聚碳酸酯提供了一种新思路.

摘要：Many rock avalanches were triggered by the Wenchuan earthquake on May 12, 2008 in southwest China. Protection galleries covered with a single soil layer are usually used to protect against rockfall. since one-layer protection galleries do not have sufficient buffer capacity, a two-layered absorbing system has been designed. This study aims to find whether an expanded poly-styrol （EPS） cushion, which is used in the soil-covered protection galleries for shock absorption, could be positioned under dynamic loadings. The dynamic impacts of the two-layered absorbing system under the conditions of rock avalanches are numerically simulated through a 2D discrete dement method. By selecting reasonable parameters, a series of numerical experiments were conducted to find the best combination for the two- layered absorbing system. The values of the EPS layer area as a percentage of the total area were set as 0% （Sl）, 22~ （S2）, and 70% （$3）. 22~ of the area of the EPS layer was found to be a reasonable value, and experiments were conducted to find the best position of the EPS layer in the two-layered absorbing system. The numerical results yield useful conclusions regarding the interaction between the impacting avalanches and the two-layered absorbing system. The soil layer can absorb the shock energy effectively and S2 （0.4-m thick EPS cushion covered with soil layer） is the most efficient combination, which can reduce the impact force, compared with the other combinations.
