【摘要】 以硫色满酮为起始原料合成一系列新型的烯胺类化合物。12个烯胺类化合物均未见报道,其结构由UV-vis,IR,HRMS,1HNMR和13CNMR确认。二维NMR证明这一类化合物在室温条件下是以烯胺酮结构存在而不是西佛碱的结构。采用二倍浓度稀释法(平板法)测试各目标化合物的体外抗真菌活性,实验选用两种临床上常用的致病真菌为测试菌株。活性测试结果表明化合物(反)-8-氯-3-((4-硝基苯基氨基)亚甲基)硫色满-4-酮(4j)对新生隐球菌的最小抑菌浓度为32μg·ml-1优于对照药氟康唑64μg·ml-1。更多还原

【Abstract】 A series of novel enaminones has been synthesized by using thiochroman-4-ones as the starting material.The structure of the new compounds is characterized by UV-vis,IR,HRMS,1HNMR,and 13CNMR.2D NMR spectroscopic studies revealed that these compounds exist in the keto-enamine form not Schiff base form at room temperature.The synthesized compounds were evaluated against two species of fungi in vitro by agar cup plate and micro-titration methods,respectively.The results of antifungal screening reveal that the MIC value of (E)-8-chloro-3-((4-nitrophenylamino)methylene)thiochroman-4-one (4j) against C.albicas is 32 μg·ml-1 while the contrast Fcz is 64 μg·ml-1.更多还原
