Compounds (18)

CompoundDescription
hydronium ion
tamoxifenOne of the SELECTIVE ESTROGEN RECEPTOR MODULATORS with tissue-specific activities. Tamoxifen acts as an anti-estrogen (inhibiting agent) in the mammary tissue, but as an estrogen (stimulating agent) in cholesterol metabolism, bone density, and cell proliferation in the ENDOMETRIUM.
uridine diphosphateA uracil nucleotide containing a pyrophosphate group esterified to C5 of the sugar moiety.
formaldehydeA highly reactive aldehyde gas formed by oxidation or incomplete combustion of hydrocarbons. In solution, it has a wide range of uses: in the manufacture of resins and textiles, as a disinfectant, and as a laboratory fixative or preservative. Formaldehyde solution (formalin) is considered a hazardous compound, and its vapor toxic. (From Reynolds, Martindale The Extra Pharmacopoeia, 30th ed, p717)
WaterA clear, odorless, tasteless liquid that is essential for most animal and plant life and is an excellent solvent for many substances. The chemical formula is hydrogen oxide (H2O). (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
OxygenAn element with atomic symbol O, atomic number 8, and atomic weight [15.99903; 15.99977]. It is the most abundant element on earth and essential for respiration.
N,N-didesmethyl-4-hydroxytamoxifenstructure in first source
afimoxifene
4-hydroxy-n-desmethyltamoxifenmetabolite of tamoxifen in human bile
adenosine 3'-phosphate-5'-phosphate
uridine diphosphate glucuronic acidA nucleoside diphosphate sugar which serves as a source of glucuronic acid for polysaccharide biosynthesis. It may also be epimerized to UDP iduronic acid, which donates iduronic acid to polysaccharides. In animals, UDP glucuronic acid is used for formation of many glucosiduronides with various aglycones.
tamoxifen n-oxide
desdimethyltamoxifen
alpha-hydroxytamoxifenstructure in first source
n-desmethyltamoxifenmain metabolite of tamoxifen; RN given refers to (Z)-isomer
phosphoadenosine phosphosulfate3'-Phosphoadenosine-5'-phosphosulfate. Key intermediate in the formation by living cells of sulfate esters of phenols, alcohols, steroids, sulfated polysaccharides, and simple esters, such as choline sulfate. It is formed from sulfate ion and ATP in a two-step process. This compound also is an important step in the process of sulfur fixation in plants and microorganisms.
