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.
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.
