Mechanochemical reactions achieved by processes such as milling and grinding are promising alternatives to traditional solution-based chemistry. This approach not only eliminates the need for large amounts of solvents, thereby reducing waste generation, but also finds applications in chemical and materials synthesis. The focus of this study is on the synthesis of quinazolinone derivatives by ball milling, in particular evodiamine and rutaecarpine analogues.

Article Synopsis
  • - The study investigates the anti-aging potential of Cosmos caudatus Kunth (CC), focusing on its ability to inhibit collagen degradation and matrix metalloproteinases (MMPs) that contribute to skin aging.
  • - CC extracts showed significant antioxidant activity and were effective in inhibiting collagenase and MMP-1 and MMP-3 in human dermal fibroblasts without being toxic to the cells.
  • - Important bioactive compounds, including quercitrin and quercetin, were isolated and quantified from the CC extracts, indicating that these compounds may play a key role in the skin anti-aging effects of CC.
