Neopterin belongs to the chemical group known as pteridines. It is synthesised by macrophages upon stimulation with the cytokine interferon-gamma and is indicative of a pro-inflammatory immune status. Neopterin serves as a marker of cellular immune system activation. [Wikipedia]. Erythroneopterin is found in soy bean. 6-(D-Erythro-1,2,3-Trihydroxypropyl)pterin 6-D-Erythro-Neopterin D-Erythro-neopterin D-Neopterin Neopterin C9H11N5O4 253.2147 253.081103865 2-amino-6-[(1S,2R)-1,2,3-trihydroxypropyl]-3,4-dihydropteridin-4-one 2-amino-6-[(1S,2R)-1,2,3-trihydroxypropyl]-3H-pteridin-4-one 2009-64-5 NC1=NC2=C(N=C(C=N2)[C@H](O)[C@H](O)CO)C(=O)N1 InChI=1S/C9H11N5O4/c10-9-13-7-5(8(18)14-9)12-3(1-11-7)6(17)4(16)2-15/h1,4,6,15-17H,2H2,(H3,10,11,13,14,18)/t4-,6+/m1/s1 BMQYVXCPAOLZOK-XINAWCOVSA-N belongs to the class of organic compounds known as biopterins and derivatives. These are coenzymes containing a 2-amino-pteridine-4-one derivative. They are mainly synthesized in several parts of the body, including the pineal gland.
