6-trimethoxyacetophenone (HTMCX) and benzaldehyde. The molecular structure of this chalcone was determined by Nuclear Magnetic Resonance, and characterized by infrared and Raman spectroscopy, at room temperature. Its electrochemical behavior was also evaluated. Vibrational wavenumber and wavevector have been predicted using the Density Functional Theory (DFT) calculations and their normal modes were analyzed in terms
摘要 查耳酮是生物合成类黄酮及其衍生物等生物活性化合物的重要中间体。本文通过缩合反应合成了一种新型查耳酮2E-1-(2ʹ-Hydroxy-3ʹ,4ʹ,6ʹ-三甲氧基苯基)-3-(苯基)-prop-2-en-1(HYTPHENYL)。 Claisen-Schmidt 在介于 2-羟基-3,4,6-三甲氧基苯乙酮 (HTMCX) 和苯甲醛之间的碱性介质中。该查耳酮的分子结构由核磁共振确定,并在室温下通过红外和拉曼光谱表征。还评估了其电化学行为。已经使用密度泛函理论 (DFT) 计算预测了振动波数和波矢量,并根据势能分布 (PED) 分析了它们的正常模式。此外,进行DFT计算以获得分子轨道和静电表面图。测量 HYTPHENYL 的电子吸收光谱并与 HTMCX 化合物的电子吸收光谱进行比较。此外,还进行了抗菌活性和抗生素耐药性调节的分析,以评估 HYTPHENYL 查耳酮的抗菌潜力。
