Antioxidant activity of 1.3-bis(p-hydroxyphenyl)urea by CUPRAC and FRAP methods

Indonesian Journal of Pharmaceutical and Clinical Research, 2023
An imbalance in the number of free radicals produced in the body can result in oxidative stress. Excessive oxidative stress can lead to chronic inflammation, which in turn can lead to most chronic diseases. Inflammation is related to oxidation through increased reactive oxidative stress, which can target modulators associated with inflammation, such as
