Azabicyclo[x.1.1]alkanes (ABCAs) are a class of nitrogen-containing bridged-ring compounds. Compared with planar structures such as benzene rings and conformationally flexible nitrogen-containing heterocycles such as piperazines and diazepanes, these molecules possess greater rigidity and more ...
Aryl nitriles are common structural motifs in the synthesis of pharmaceuticals, agrochemicals, and functional materials. The nitrile group can either be retained as a stable functional group in the target molecule or further converted into amides, carboxylic acids, amines, ketones, and ...
During lead optimization, medicinal chemists often need to introduce small C(sp³) fragments—such as methyl, cyclopropyl, difluoromethyl, hydroxymethyl, oxetanyl, and bicyclo[1.1.1]pentyl groups—onto the same molecular scaffold to investigate how changes in substituents affect biological ...
Bicyclo[1.1.1]pentane, or BCP, is a rigid cage-like framework. The two bridgehead substituents in 1,3-disubstituted BCPs extend in directions approaching 180°, making this scaffold useful in studies involving three-dimensional bioisosteric replacement of para-disubstituted benzene rings. ...
GPCRs, integrins, and receptor tyrosine kinases regulate actin polymerization, contraction, and adhesion turnover through Rho family small GTPases, thereby controlling cell migration, morphology, and tissue function.
Cell membrane microdomains are jointly organized by specific lipids, scaffold proteins, and the cytoskeleton. They can restrict membrane protein diffusion and regulate ion channels, transporters, receptor signaling, and vesicular trafficking. Abnormalities in membrane microdomain composition ...
Monkeypox virus can form mature virions and enveloped virions. Different surface antigens participate in viral attachment, membrane fusion, and cell-to-cell spread and are also important targets for nucleic acid detection, immunodiagnosis, vaccine design, and antiviral drug research.
Capryloyl salicylic acid is a derivative of salicylic acid produced through lipophilic structural modification. It retains the o-hydroxybenzoic acid structure while introducing an octanoyl group at the 5-position of the benzene ring, thereby altering the molecule’s lipid affinity, molecular ...
The benzene ring can restrict molecular conformation, control substituent orientation, and participate in target binding through hydrophobic interactions, π–π interactions, or cation–π interactions. It is therefore widely present in drug molecules. However, in some lead compounds, ...
