5-Fluorouracil (5-FU) is a uracil analog and inhibitor of DNA synthesis, exhibiting antitumor activity by affecting pyrimidine synthesis through thymidylate synthase inhibition; it induces apoptosis and autophagy.

Crystal Violet (Hexamethylpararosaniline chloride) is a triarylmethane dye that is a mixture of violet rosanilinis, with antibacterial, antifungal, and anthelmintic properties.

Dextran sulfate sodium salt (MW 4500-5500) is an anhydrous glucose polymer with a molecular weight range of 4500-5500. It inhibits human immunodeficiency virus replication by preventing viral adsorption to host cells and is commonly used to model inflammatory bowel disease. The high negative charge from its sulfate groups damages the intestinal mucosal barrier, leading to intestinal barrier dysfunction, macrophage impairment, and bacterial flora disorder.

Decanedioic acid (Sebacinsaure) is a saturated, straight-chain naturally occurring dicarboxylic acid.

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.

Rifampicin (Rifamycin AMP) is a broad-spectrum antibiotic. Rifampicin has a strong antibacterial effect against Mycobacterium tuberculosis and is also effective against gram-positive and gram-negative bacteria and viruses.
