boldine

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. — NCATS
