Abstract

The pursuit of multifunctional therapeutic agents remains crucial in combating oxidative stress and microbial resistance. In this study, we synthesized and characterized a diverse series of novel isatin-based derivatives (12a–z), exploring their antioxidant and antimicrobial potential. Notably, compound 12c demonstrated remarkable antioxidant efficacy among all isatin-based derivatives, with an IC₅₀ value of 9.79 ± 0.168 µg/mL in the DPPH radical scavenging assay, positioning it as a potent radical scavenger comparable to the standard (ascorbic acid). Furthermore, antimicrobial screening identified compounds 12a and 12b as standout candidates, showcasing strong antibacterial and antifungal properties through disc-diffusion and broth dilution methods. These promising bioactivities underscore the potential of 12a, 12b and 12c as therapeutic agents, meriting further investigation for their application in oxidative stress-related conditions and infectious disease management. This study lays the groundwork for future development of isatin derivatives as pharmacologically relevant molecules in both antioxidant and antimicrobial domains.

新型Isatin衍生物的合成、表征及抗氧化抗菌活性评价
追求多功能治疗剂仍然是对抗氧化应激和微生物耐药性的关键。在这项研究中,我们合成并表征了一系列新的isatin-based衍生物(12a-z),探索它们的抗氧化和抗菌潜力。值得注意的是,化合物12c在所有istin基衍生物中表现出卓越的抗氧化功效,在DPPH自由基清除实验中IC₅0值为9.79±0.168 μ g/mL,将其定位为与标准(抗坏血酸)相当的有效自由基清除剂。此外,抗菌筛选发现化合物12a和12b是突出的候选者,通过圆盘扩散和肉汤稀释方法显示出强大的抗菌和抗真菌性能。这些有希望的生物活性强调了12a, 12b和12c作为治疗药物的潜力,值得进一步研究其在氧化应激相关疾病和传染病管理中的应用。该研究为今后开发isatin衍生物作为抗氧化和抗菌领域的药理学相关分子奠定了基础。

期刊介绍: Archiv der Pharmazie - Chemistry in Life Sciences is an international journal devoted to research and development in all fields of pharmaceutical and medicinal chemistry. Emphasis is put on papers combining synthetic organic chemistry, structural biology, molecular modelling, bioorganic chemistry, natural products chemistry, biochemistry or analytical methods with pharmaceutical or medicinal aspects such as biological activity. The focus of this journal is put on original research papers, but other scientifically valuable contributions (e.g. reviews, minireviews, highlights, symposia contributions, discussions, and essays) are also welcome.
