Common Name

Ethylmorphine Description

A narcotic analgesic and antitussive. It is metabolized in the liver by ethylmorphine-N-demethylase and used as an indicator of liver function. It is not marketed in the US but is approved for use in various countries around the world. In the US it is a schedlie II drug (single-entity) and schedlie III drug (in combination products).

    Enzymes

    General function:
    Involved in oxidoreductase activity
    Specific function:
    This enzyme is required for electron transfer from NADP to cytochrome P450 in microsomes. It can also provide electron transfer to heme oxygenase and cytochrome B5.
    Gene Name:
    POR
    Uniprot ID:
    P16435
    Molecular weight:
    77047.575
    General function:
    Involved in monooxygenase activity
    Specific function:
    Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It performs a variety of oxidation reactions (e.g. caffeine 8-oxidation, omeprazole sulphoxidation, midazolam 1-hydroxylation and midazolam 4-hydroxylation) of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics. Acts as a 1,8-cineole 2-exo-monooxygenase. The enzyme also hydroxylates etoposide.
