Application

Ro 41-0960 has been used as an inhibitor of catechol-O-methyl-transferase in synaptosome membrane preparations [1] and 3T3-L1 adipocytes.[2] It has also been used as a catechol-O-methyl-transferase inhibitor to treat corpus striatum samples to test its effect on dopamine metabolism.[3]

Biochem/physiol Actions

Ro 41-0960 is a specific and synthetic inhibitor of the enzyme catechol-O-methyl-transferase (COMT).[4] It binds to the catalytic site and triggers the inhibition of the methylation property of COMT.[5] Ro 41-0960 is effective on uterine leiomyoma lesions and uterine fibroids.[4]

A valine-to-isoleucine mutation at position 122 of the serum protein transthyretin (TTR), found in 3 to 4% of African Americans, alters its stability, leading to amyloidogenesis and cardiomyopathy. In addition, 10 to 15% of individuals older than 65 years develop

A solid body of preclinical evidence shows that glucagon-like peptide-1 receptor (GLP-1R) agonists attenuate the effects of substance use disorder related behaviors. The mechanisms underlying these effects remain elusive. In the present study, we hypothesized that GLP-1R activation modulates dopaminetransporter

Phytochemicals are natural dietary constituents of fruits and vegetables. Some of these phytochemicals are known to affect estrogen-metabolizing enzymes. In breast tissue, estradiol can be metabolized to the catechol estrogens 2- and 4-hydroxyestradiol (2-OHE(2) and 4-OHE(2)). Catechol estrogens are suspected

Uterine leiomyomas (fibroids) are the most common pelvic tumors in women. We assessed the potential therapeutic utility of Ro 41-0960, a synthetic catechol-O-methyl transferase inhibitor (COMTI), in the Eker rat. We randomized uterine fibroid-bearing Eker rats for treatment with Ro

Formation of estrogen metabolites that react with DNA is thought to be a mechanism of cancer initiation by estrogens. The estrogens estrone (E(1)) and estradiol (E(2)) can form catechol estrogen (CE) metabolites, catechol estrogen quinones [E(1)(E(2))-3,4-Q], which react with DNA
