Editorial: Medicinal chemistry of active pharmaceutical ingredients of drug products.

This document is an editorial from the journal Frontiers in Chemistry titled "Medicinal chemistry of active pharmaceutical ingredients of drug products." It discusses the importance of active pharmaceutical ingredients (APIs) in drug products and the need for suitable APIs to comply with specific dosage form characteristics. The editorial highlights three research studies related to medicinal chemistry. The first study explores the anti-ulcerative colitis effects of extracts from Calliandra haematocephala. The second study focuses on the quality evaluation of compounds in leaves of six Taxus species. The third study investigates the chemical fingerprinting and biological properties of the essential oil from Eucalyptus globulus leaves. The authors conclude that these studies provide valuable insights into potential therapeutic approaches for various diseases. [Extracted from the article]
