70s ribosome

Hygromycin B (Hygrovetine) is an aminoglycoside antibiotic that inhibits protein synthesis in both prokaryotic and eukaryotic cells by interfering with translocation and causing mistranslation by the 70S ribosome. It is commonly used for the selection of cells transfected with the hph or hyg resistance gene.

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.

L-NAME hydrochloride is an inhibitor of nitric oxide synthase (NOS) with an IC₅₀ of 70 μM, and it can be used to induce hypertension and kidney injury models.
