摘要：本文设计、合成了14个新型L-脯氨酸类化合物,并考察了它们对乙酰胆碱酯酶的体外抑制活性。以α-溴代苯乙酮为原料,经过4步反应,合成了新型L-脯氨酸类化合物;并采用Ellman分光光度法测试了它们对乙酰胆碱酯酶的体外抑制活性。测试结果表明,目标化合物具有一定的乙酰胆碱酯酶抑制活性,其中化合物8b的抑制活性最好,其IC50达到了5.45μmol·L-1,优于对照药利斯的明。L-脯氨酸类化合物对乙酰胆碱酯酶具有较好的抑制活性,值得进一步研究。

摘要：目的设计合成2,3,3a,4-四氢硫色烯并[4,3-c]吡唑类化合物,并对其体外抗真菌活性进行初步评价。方法以取代苯硫酚为起始原料,合成中间体3-次苄基硫色满酮,该中间体与水合肼在热醋酸中反应生成目标化合物。采用二倍稀释法对4种受试真菌——絮状表皮毛癣菌(***)、石膏样小孢子菌(***-um)、绿色木霉菌(***)和断发毛癣菌(***)进行体外抗真菌活性测试。结果合成了12个新的2,3,3a,4-四氢硫色烯并[4,3-c]吡唑类化合物,其结构经氢核磁共振谱、质谱和元素分析确证。抗真菌实验结果表明,所合成的目标化合物对供试真菌具有一定程度的抑制活性。结论2,3,3a,4-四氢硫色烯并[4,3-c]吡唑类化合物具有体外抗真菌活性。

摘要：As epoxy functional group has high anticancer activity, α, β-epoxyketones were designed and synthesized as new anticancer agents, and their structures were confirmed by UV, 1H NMR, IR, MS technigeces and elemental analysis. Their in vitro anticancer activities were evaluated by MTF method and the results showed that the compound 4c exhibited good activity with IC50 of 17.8, 22.0 and 24.1 μg/mL against A-549, Hela and HepG2 cells, respectively. The dose of LD50 of the mice by intragastric administration was 1864.4 mg/kg. Therefore, the α, β-epoxyketones could potentially provide as new anticancer agents.
