Looking at its structure, the main framework is quinoline derivatives. The quinoline ring is formed by fusing a benzene ring with a pyridine ring, which is the key structural unit of many drugs and biologically active molecules. In this compound, the 4-position oxygen atom of the quinoline ring forms a carbonyl structure, which imparts specific chemical activity and spatial conformation to the molecule, and plays an important role when interacting with other molecules, or through hydrogen bonding, electrostatic interaction and other forces. The introduction of the
6-position iodine atom significantly changes the molecular electron cloud distribution and steric hindrance. The iodine atom has a large atomic radius and electronegativity, which affects the molecular dipole moment and lipophilicity, or enhances its ability to bind to receptors, or affects the transmembrane transport properties of molecules. The existence of the
7-position fluorine atom should not be underestimated. Although the fluorine atom is small, its electronegativity is extremely high, which can significantly affect the physical and chemical properties of molecules. It may change the acidity and alkalinity of molecules and enhance molecular stability. In drug design, the introduction of fluorine atoms often improves the metabolic stability and bioavailability of drugs.
1-linked (1-hydroxy-3-methylbutyl-2-yl) group adds a side chain containing hydroxyl groups and methyl groups to the molecule. Hydroxy groups are hydrophilic and can participate in hydrogen bond formation, enhancing the interaction between molecules and biomacromolecules; methyl groups increase molecular hydrophobicity, affecting molecular solubility and distribution in biofilms. The ethyl carboxylate group at the position of
3 not only contains the chemical activity of the ester group, but also can undergo hydrolysis, alcoholysis and other reactions. Due to the spatial and electronic effects of the ethyl ester structure, it makes an important contribution to the activity and properties of the whole molecule.
