Synthesis of Novel Fluorescent Cyclohexenone Derivatives and their Partitioning Study in Ionic Micellar Media
摘要:
本文展示了一种通过乙酰乙酸乙酯迈克尔加成的简便方法合成四种新型环己烯酮衍生物(CDs)的方法。通过傅立叶变换红外光谱、1H NMR、EIMS、紫外光谱以及 X 射线单晶结构分析确认了 CD 的分子结构。CDs 是一种强荧光化合物,其荧光光谱显示出强烈的紫色荧光。为了模拟与生物膜的结合,还研究了 CD 在阳离子表面活性剂十六烷基三甲基溴化铵(CTAB)和阴离子表面活性剂十二烷基硫酸钠(SDS)的胶束溶液中的行为。通过紫外-可见光谱和荧光光谱技术研究了 CD 与 CTAB 和 SDS 的分配和结合相互作用的特征。与 SDS 相比,CTAB 的上述相互作用值更高,这表明 CD 与 CTAB 之间的相互作用大于与 SDS 之间的相互作用。
In this study, a series of novel beta-mercapto carbonyl derivatives (3a-j) was prepared by addition of thiophenol (2) to chalcones (1a-j) in the presence of catalytic amount of iodine (10 mol%) in CH2Cl2. Antibacterial and antifungal in vitro properties of the synthesized compounds were tested against some human pathogenic microorganisms by employing the disk diffusion technique. For the most active compounds, also minimum inhibitory concentrations (MICs) were determined.
