Cyclohexane is an organic compound with a chemical formula C6H12. It is a colorless liquid with a pungent odor, insoluble in water, and soluble in most organic solvents such as ethanol, ether, benzene, and acetone. Cyclohexyl fragments are a common structure in both natural and synthetic drugs. It can be used as both core structure and part of achiral side chain.
Nitrogen-containing heterocyclic compounds have a wide range of applications in medicine, organic materials, natural products and other fields, mainly for biologically active molecules. Pyrrolopyrazines contain pyrrole and pyrazine rings as bioactive scaffolds. Compounds containing this scaffold have a wide range of biological activities, such as antibacterial, anti-inflammatory, antiviral, antifungal, antioxidant, antitumor, and kinase inhibition.
