Distribution, properties, and inhibitor sensitivity of zebrafish catechol-O-methyl transferases (COMT)

Pulmonary O-methyl transferases.

An investigation 111 vitro of pulmonary O-methyl transferases rcvcaled the presence of microsomal phenol-O-methyl transferase and soluble and microsomal catechol-O-methyl transferases in guineapig lung tissue. Both phenol and catechol transferases also were detected in rat and rabbit lung tissue. Substrates of guinea-pig pulmonary phenol-0-mcth!l transfcrasc ~ncludcJ phenols. crcsols and xyleno...

Docking Based De novo Design of Few Tolcapone Derivatives as Catechol-o- Methyl Transferase (Comt) Inhibitors

Catechol-O-methyl tranferase (COMT; E.C.2.1.1.6) is widely distributed enzyme in nature that plays an essential role in the metabolism of catechol neurotransmitters and catechol linked foreign entities. As L-DOPA, a key medicine in Parkinsonism is being catabolised by COMT, this justified the interest in developing improved COMT inhibitors as significant adjunct to L-DOPA therapy. Although tolc...

Distribution, regulation and physiological roles of catechol-O-methyltransferase (COMT) in rodents

Catechol-O-methyltransferase (COMT)-mediated metabolism of catechol estrogens: comparison of wild-type and variant COMT isoforms.

The oxidative metabolism of 17beta-estradiol (E2) and estrone (E1) to catechol estrogens (2-OHE2, 4-OHE2, 2-OHE1, and 4-OHE1) and estrogen quinones has been postulated to be a factor in mammary carcinogenesis. Catechol-O-methyltransferase (COMT) catalyzes the methylation of catechol estrogens to methoxy estrogens, which simultaneously lowers the potential for DNA damage and increases the concen...

Hypnotizability and Catechol-O-Methyltransferase (COMT) polymorphysms in Italians

Higher brain dopamine content depending on lower activity of Catechol-O-Methyltransferase (COMT) in subjects with high hypnotizability scores (highs) has been considered responsible for their attentional characteristics. However, the results of the previous genetic studies on association between hypnotizability and the COMT single nucleotide polymorphism (SNP) rs4680 (Val(158)Met) were inconsis...
