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.
The quinones are a class of organic compounds that are formally derived from aromatic compounds by conversion of an even number of –CH= groups into –C(=O)– groups with any necessary rearrangement of double bonds, resulting in a fully conjugated cyclic dione structure. Quinones exhibit numerous biological activities such as neurological, antibacterial, antiplasmodial, antioxidantal, trypanocidal, antitumor, and anti-HIV, and these activities have been proven to be related to the redox properties of their carbonyl functions.
