Usage

General Description

Vitamin K5, also known as menadione, is a synthetic form of vitamin K. It plays a crucial role in blood clotting and bone metabolism. It is an essential nutrient that helps in the production of proteins necessary for blood coagulation and regulating calcium levels in the body. Vitamin K5 is also involved in the maintenance of healthy bones and in preventing osteoporosis. Additionally, it has antioxidant properties and may help protect cells from damage caused by free radicals. Overall, vitamin K5 is important for overall health and well-being.

DPPH radical scavenging activity of paracetamol analogues

Biochemical studies suggest a direct relationship between the radical scavenging activity of paracetamol (I) and its antipyretic and analgesic action. To evaluate the effect of chemical modifications on the radical scavenging activity of compounds of type I, analogues 1-14 were prepared and submitted to a stable free radical (DPPH; 1,1-diphenyl-2-picryl-hydrazyl) assay. All paracetamol derivatives showed a significant higher efficiency than the parent compound. This study showed that radical scavenging activity can be increased by decreasing the phenolic ortho substituents steric hindrance or by introducing substituents on the acyl moiety like an indazole ring or the ionic N-methyl morpholinium group. A significant activating effect was also observed by replacing the 1,4-acylamidophenol with a 1,4-acylamidonaphthol system.
