Substance | Relationship Strength | Studies | Trials | Classes | Roles |
chlorine chloride : A halide anion formed when chlorine picks up an electron to form an an anion. | 1.96 | 1 | 0 | halide anion; monoatomic chlorine | cofactor; Escherichia coli metabolite; human metabolite |
hydrogen Hydrogen: The first chemical element in the periodic table with atomic symbol H, and atomic number 1. Protium (atomic weight 1) is by far the most common hydrogen isotope. Hydrogen also exists as the stable isotope DEUTERIUM (atomic weight 2) and the radioactive isotope TRITIUM (atomic weight 3). Hydrogen forms into a diatomic molecule at room temperature and appears as a highly flammable colorless and odorless gas.. dihydrogen : An elemental molecule consisting of two hydrogens joined by a single bond. | 1.96 | 1 | 0 | elemental hydrogen; elemental molecule; gas molecular entity | antioxidant; electron donor; food packaging gas; fuel; human metabolite |
tyrosine Tyrosine: A non-essential amino acid. In animals it is synthesized from PHENYLALANINE. It is also the precursor of EPINEPHRINE; THYROID HORMONES; and melanin.. tyrosine : An alpha-amino acid that is phenylalanine bearing a hydroxy substituent at position 4 on the phenyl ring. | 2 | 1 | 0 | amino acid zwitterion; erythrose 4-phosphate/phosphoenolpyruvate family amino acid; L-alpha-amino acid; proteinogenic amino acid; tyrosine | EC 1.3.1.43 (arogenate dehydrogenase) inhibitor; fundamental metabolite; micronutrient; nutraceutical |
methylergonovine Methylergonovine: A homolog of ERGONOVINE containing one more CH2 group. (Merck Index, 11th ed) | 3.42 | 1 | 1 | ergoline alkaloid | |
mifepristone Mifepristone: A progestational and glucocorticoid hormone antagonist. Its inhibition of progesterone induces bleeding during the luteal phase and in early pregnancy by releasing endogenous prostaglandins from the endometrium or decidua. As a glucocorticoid receptor antagonist, the drug has been used to treat hypercortisolism in patients with nonpituitary CUSHING SYNDROME. | 3.37 | 1 | 1 | 3-oxo-Delta(4) steroid; acetylenic compound; tertiary amino compound | abortifacient; contraceptive drug; hormone antagonist; synthetic oral contraceptive |
oxytocin Oxytocin: A nonapeptide hormone released from the neurohypophysis (PITUITARY GLAND, POSTERIOR). It differs from VASOPRESSIN by two amino acids at residues 3 and 8. Oxytocin acts on SMOOTH MUSCLE CELLS, such as causing UTERINE CONTRACTIONS and MILK EJECTION.. oxytocin : A cyclic nonapeptide hormone with amino acid sequence CYIQNCPLG that also acts as a neurotransmitter in the brain; the principal uterine-contracting and milk-ejecting hormone of the posterior pituitary. Together with the neuropeptide vasopressin, it is believed to influence social cognition and behaviour. | 3.09 | 1 | 0 | heterodetic cyclic peptide; peptide hormone | oxytocic; vasodilator agent |
dinoprost Dinoprost: A naturally occurring prostaglandin that has oxytocic, luteolytic, and abortifacient activities. Due to its vasocontractile properties, the compound has a variety of other biological actions.. prostaglandin F2alpha : A prostaglandins Falpha that is prosta-5,13-dien-1-oic acid substituted by hydroxy groups at positions 9, 11 and 15. It is a naturally occurring prostaglandin used to induce labor. | 7.92 | 15 | 5 | monocarboxylic acid; prostaglandins Falpha | human metabolite; mouse metabolite |
15-ketoprostaglandin f2alpha [no description available] | 1.96 | 1 | 0 | prostaglandins Falpha | |
misoprostol Misoprostol: A synthetic analog of natural prostaglandin E1. It produces a dose-related inhibition of gastric acid and pepsin secretion, and enhances mucosal resistance to injury. It is an effective anti-ulcer agent and also has oxytocic properties.. misoprostol : A diastereoisomeric mixture composed of approximately equal amounts of a double racemate of four of the sixteen possible diastereoisomers of methyl (13E)-11,16-dihydroxy-16-methyl-9-oxoprost-13-en-1-oate that is racemic prostaglandin E1 which is lacking the hydroxy group at position 15, but which has an additional hydroxy group at position 16. It is a synthetic prostaglandin E1 analogue, used in the treatment of gastric and duodenal ulcers. A weak abortifacient, it is also used for cervical ripening prior to surgical termination of pregnancy. The (11R,16S)-diastereoisomer is the pharmacologically active form. | 3.41 | 1 | 1 | | |
arbaprostil Arbaprostil: A synthetic prostaglandin E analog that protects the gastric mucosa, prevents ulceration, and promotes healing of peptic ulcers. The protective effect is independent of acid inhibition. It is also a potent inhibitor of pancreatic function and can inhibit the growth of experimental tumors. | 1.96 | 1 | 0 | prostanoid | |
