Doxycycline is an orally active tetracycline antibiotic with broad-spectrum inhibitory effects on matrix metalloproteinases (MMPs), possessing both antibacterial and antitumor activities, and is commonly used in inducible gene expression ON-OFF systems.

Doxycycline (hyclate) is an orally active tetracycline antibiotic with broad-spectrum inhibitory activity against matrix metalloproteinases (MMPs), possessing both antibacterial and antitumor properties, and is commonly used in inducible gene expression ON-OFF systems.

Tetracycline is an orally active broad-spectrum antibiotic that exhibits inhibitory activity against various Gram-positive and Gram-negative bacteria, as well as Chlamydia, Mycoplasma, and Rickettsia. It is commonly used in anti-infection research and can also be used to induce tumor regression based on BCR-ABL gene silencing.

Cyclosporin A is a natural product and an active fungal metabolite, classified as a cyclic polypeptide immunosuppressant. It binds to cyclophilin and inhibits the activity of calcineurin (IC₅₀ = 7 nM) as well as CD11a/CD18 adhesion molecules. It is commonly used to induce uremia models.

Urethane (Ethyl carbamate; Ethylurethane) is a byproduct formed during the fermentation process of various foods. As an ethyl ester of carbamic acid, it has the ability to inhibit the growth of bacteria, sea urchin eggs, protozoa, and plant tissues, and is commonly used for establishing lung cancer models.

Capsaicin is an active natural component found in chili peppers and acts as a TRPV1 agonist (EC50 = 0.29 μM). It possesses multiple activities, including pain relief, antitumor, anti-inflammatory, antioxidant, and neuroprotective effects, as well as some neurotoxicity. Capsaicin can be used to establish itch models.

Terephthalic acid is an isomer and a precursor of the polyester PET. It is used in the production of textiles and plastics, and can also be used to establish skin cancer models.
