Toquizine is an anticholinergic agent. It was used as an antiulcer agent.

Boldine, an aporphine alkaloid, found abundantly in the leaves/bark of boldo (Peumus boldus Molina) widely consumed in the folk medicine of some regions. Boldine possesses various pharmacological properties including, anticancer activity. It exhibits a significant improvement of learning and memory through inhibition of brain acetylcholinesterase activity and alleviation of brain oxidative stress, which was shown on animal models. Boldine is a potentially useful agent for the treatment of leishmaniosis. In addition, it suppresses osteoclastogenesis, improves bone destruction and may be a potential therapeutic agent for rheumatoid arthritis. Besides, was shown, that boldine inhibits telomerase in cells treated with sub-cytotoxic concentrations. Telomerase inhibition occurs via down-regulation of human telomerase reverse transcriptase (hTERT), the catalytic subunit of the enzyme.

Geneticin (G-418) is produced by Micromonospora phodorangea. The antibiotic has brad spectrum antibacterial activity similar to gentamicins and other previously described aminoglycosides but of particular interest because of its high activity against protozoa, amoebae, tapeworm and pinworm infections in mice. G418 blocks polypeptide synthesis by inhibiting the elongation step in both prokaryotic and eukaryotic cells. G418 is commonly used in laboratory research to select genetically engineered cells.
