This study employs electrochemical and Density Functional Theory (DFT) calculation approaches to investigate the potential of a novel analogue of trimetozine (TMZ) antioxidant profile. The correlation between oxidative stress and psychological disorders indicates that antioxidants may be an effective alternative treatment option. Butylatedhydroxytoluene (BHT) is a synthetic antioxidant widely used in industry. The BHT-TMZ compound derived from molecular hybridization, known as LQFM289, has shown promising results in early trials, and this study aims to elucidate its electrochemical properties to further support its potential as a therapeutic agent. The electrochemical behavior of LQFM289 was investigated using voltammetry and a mechanism for the redox process was proposed based on the compound's behavior. LQFM289 exhibits two distinct oxidation peaks: the first peak, ≈ 0.49, corresponds to the oxidation of the phenolic fraction (BHT), and the second peak, ≈ 1.2 V (vs. Ag/AgCl/KCl), denotes the oxidation of the amino group from morpholine. Electroanalysis was used to identify the redox potentials of the compound, providing insight into its reactivity and stability in different environments. A redox mechanism was proposed based on the resulting peak potentials. The DFT calculation elucidates the electronic structure of LQFM289, resembling the precursors of molecular hybridization (BHT and TMZ), which may also dictate the pharmacophoric performance.
本研究采用电化学和密度泛函理论(DFT)计算方法,研究了一种新型三甲嗪(TMZ)抗氧化特性类似物的潜力。氧化应激与心理障碍之间的相关性表明,抗氧化剂可能是一种有效的替代治疗选择。丁基化羟基甲苯(BHT)是一种广泛应用于工业的合成抗氧化剂。由分子杂交衍生的 BHT-TMZ 化合物,称为 LQFM289,在早期试验中显示出有希望的结果,本研究旨在阐明其电化学性质,以进一步支持其作为治疗剂的潜力。使用伏安法研究了 LQFM289 的电化学行为,并根据化合物的行为提出了氧化还原过程的机理。LQFM289 表现出两个明显的氧化峰:第一个峰约为 0.49,对应于酚部分(BHT)的氧化,第二个峰约为 1.2 V(相对于 Ag/AgCl/KCl),表示吗啉氨基的氧化。电分析用于确定化合物的氧化还原电位,深入了解其在不同环境中的反应性和稳定性。基于所得峰电位提出了氧化还原机制。DFT 计算阐明了 LQFM289 的电子结构,类似于分子杂交的前体(BHT 和 TMZ),这也可能决定了药效构象的性能。
