Revealing the Antioxidant Potential of 1,3-BIS Compounds (P-hydroxyphenyl) Urea: An In-depth Study with the Cuprac and FRAP Methods

Introduction

Free radicals are highly reactive molecules that can cause oxidative stress and damage to cells, leading to various diseases and health issues. The human body has a natural defense mechanism against free radicals, but it can be overwhelmed by excessive exposure to environmental stressors, such as pollution, UV radiation, and smoking. In recent years, there has been a growing interest in the development of antioxidants as a potential solution to mitigate the harmful effects of free radicals. 1,3-BIS compounds (P-hydroxyphenyl) Urea, a synthetic compound derived from p-aminofenol, has been shown to possess anti-inflammatory properties and reduce the side effects of paracetamol. This study aims to investigate the antioxidant activity of 1,3-BIS compounds (P-hydroxyphenyl) Urea using the Cuprac (Cupric Ion Reducing Antioxidant Capacity) and FRAP (Ferric Reducing Antioxidant Power) methods.

The Importance of Antioxidants

Antioxidants play a crucial role in maintaining the body's homeostasis by neutralizing free radicals and preventing oxidative stress. The imbalance between the production of free radicals and the body's antioxidant defenses can lead to various diseases, including cancer, atherosclerosis, and neurodegenerative disorders. 1,3-BIS compounds (P-hydroxyphenyl) Urea, with its potential antioxidant properties, may offer a new avenue for the development of therapeutic agents that can mitigate the harmful effects of free radicals.

The Cuprac and FRAP Methods

The Cuprac and FRAP methods are two widely used assays for measuring antioxidant activity. The Cuprac method involves the reduction of Cu (II) ions to Cu (I) using a UV-Vis spectrophotometer at a wavelength of 453 nm. The FRAP method, on the other hand, measures the ability of compounds to reduce Fe (III) ions to Fe (II) using a UV-Vis spectrophotometer at a wavelength of 702 nm. These methods provide a reliable and accurate way to assess the antioxidant potential of compounds.

The Results

The results of this study showed that 1,3-BIS compounds (P-hydroxyphenyl) Urea possess significant antioxidant activity. The IC50 value obtained by the Cuprac method was 4,4007 ± 0.07 µg/ml, while the FRAP method yielded an IC50 value of 29,3693 ± 1.20 µg/ml. These results indicate that 1,3-BIS compounds (P-hydroxyphenyl) Urea may be effective in reducing Cu (II) ions and Fe (III) ions, suggesting its potential as an antioxidant.

Deeper Analysis

The lower IC50 value obtained by the Cuprac method suggests that 1,3-BIS compounds (P-hydroxyphenyl) Urea may be more effective in reducing Cu (II) ions compared to Fe (III) ions. This is consistent with the idea that Cu (II) ions are more reactive than Fe (III) ions and may be more susceptible to reduction by antioxidants. This finding has significant implications for the development of antioxidants that can target specific types of free radicals.

Conclusion and Direction of Development

This study provides evidence for the antioxidant potential of 1,3-BIS compounds (P-hydroxyphenyl) Urea. The results of this study open up new avenues for the development of this compound as an active ingredient in health and beauty products. Further research is needed to understand the mechanism of action of antioxidants in 1,3-BIS compounds (P-hydroxyphenyl) Urea and to explore its potential for broader application.
