1-Carboxyglutamic Acid definition: Found in various tissues, particularly in four blood-clotting proteins including prothrombin, in kidney protein, in bone protein, and in the protein present in various ectopic calcifications.
Acids definition: Chemical compounds which yield hydrogen ions or protons when dissolved in water, whose hydrogen can be replaced by metals or basic radicals, or which react with bases to form salts and water (neutralization). An extension of the term includes substances dissolved in media other than water. (Grant & Hackh's Chemical Dictionary, 5th ed)
acid definition: substances whose aqueous solutions are characterized by a sour taste, the ability to turn blue litmus red, and the ability to react with bases and certain metals to form salts; yields hydrogen ions when dissolved in water, acts as a proton donor, and can accept a pair of electrons to form a covalent bond.
Acid definition: A substance that yields hydrogen ions or protons in aqueous solutions; a substance capable of accepting a pair of electrons for the formation of a coordinate covalent bond; a substance whose hydrogen can be replaced by metals or basic radicals, or which react with bases to form salts and water.
Cycloleucine definition: An amino acid formed by cyclization of leucine. It has cytostatic, immunosuppressive and antineoplastic activities.
cycloleucine definition: A synthetic amino acid derivative of cyclopentanecarboxylic acid, cycloleucine displays immunosuppressive, antineoplastic, and cytostatic properties. Believed to act in vivo as a valine antagonist and an NMDA receptor antagonist acting at the glycine site, cycloleucine is a competitive inhibitor of many enzymes, such as methionine adenosyltransferase (S-adenosylmethionine biosynthesis). Toxicity is correlated with a block of nucleic acid methylation; cell cycle progression; and DNA, RNA and protein biosynthesis.

Cycloleucine definition: A non-metabolizable synthetic amino acid, formed through the cyclization of the amino acid leucine, with immunosuppressive, antineoplastic, and cytostatic activities. Cycloleucine competitively inhibits the enzyme methionine adenosyltransferase, resulting in the inhibition of S-adenosylmethionine (SAM) synthesis from methionine and ATP, and subsequent nucleic acid methylation and polyamine production; RNA, and perhaps to a lesser extent, DNA biosyntheses and cell cycle progression are finally disrupted. This agent is also a competitive inhibitor at the glycine modulatory site of the N-methyl-D-aspartate (NMDA) receptor.
Peptide Synthases definition: Ligases that catalyze the joining of adjacent AMINO ACIDS by the formation of carbon-nitrogen bonds between their carboxylic acid groups and amine groups.
Poly I-C definition: Interferon inducer consisting of a synthetic, mismatched double-stranded RNA. The polymer is made of one strand each of polyinosinic acid and polycytidylic acid.
poly IC definition: interferon inducer consisting of a synthetic, mismatched double-stranded RNA; the polymer is made of one strand each of polyinosinic acid and polycytidylic acid.
poly IC definition: A synthetic polyinosinic-polycytidylic acid double-stranded RNA. Poly IC may stimulate the release of cytotoxic cytokines and, by inducing interferon-gamma production, may increase the number and tumoricidal activities of various immunohematopoietic cells. Check for "http://www.cancer.gov/Search/ClinicalTrialsLink.aspx?id=39558&idtype=1" active clinical trials or "http://www.cancer.gov/Search/ClinicalTrialsLink.aspx?id=39558&idtype=1&closed=1" closed clinical trials using this agent.
