Acetylcysteine (NAC) is an N-acetyl derivative of cysteine, a ROS inhibitor and mucolytic agent. Acetylcysteine induces apoptosis, can be used to reduce mucus thickness, and has anti-influenza viral activity.

Nitazoxanide (NSC-697855) is a synthetic benzamide with antiprotozoal activity. Nitazoxanide exerts its antiprotozoal activity by interfering with the pyruvate ferredoxin/flavodoxin oxidoreductase dependent electron transfer reaction.

Salcomine (NSC-32965) shows anti-influenza virus activity.

α-Vitamin E (Dexrabeprazole Sodium) is a naturally-occurring form of vitamin E, a fat-soluble vitamin with potent antioxidant properties.

β-Cyclodextrin (NSC 269471) is a member of the class of compounds known as oligosaccharides.

N-Acetylneuraminic acid (Acide aceneuramique) is a nine-carbon sialic acid monosaccharide commonly found in glycoproteins on cell membranes and in glycolipids such as gangliosides in mammalian cells. Studies have shown that N-Acetylneuraminic acid is biologically useful for neurotransmission, leukocyte extravasation, viral or bacterial infections, and carbohydrate-protein recognition.

AEBSF hydrochloride (Pefabloc SC) is an irreversible inhibitor of serine proteases, such as chymotrypsin, kallikrein, thrombin, plasmin, and trypsin.

Camphor (2-Camphanone) is a bicyclic monoterpene ketone found widely in plants, especially CINNAMOMUM CAMPHORA. It is used topically as a skin antipruritic and as an anti-infective agent.
