Described is 2-(3-aminopropyl)amino-4-hydroxy-6-[(1'R,2'S)-1',2'-dihydroxypropyl] pteridine which can be used as a cancer specific diagnostic agent and therefore is called "oncopterin". Besides, it is referred to a substance for quantitatively determining the diagnostic agent as well as detection and purification methods for the diagnostic agent. The present diagnostic agent is more specific than known cancer indicators and makes possible the routine detection on a micro scale on the basis of any body fluid, particularly urine. Oncopterin can be separated from other pteridines, like biopterin, by means of high pressure liquid chromatography (HPLC).
所述的是 2-(3-氨基丙基)氨基-4-羟基-6-[(1'R,2'S)-1',2'-二羟基丙基]蝶啶,它可用作癌症特异性诊断剂,因此被称为 "瘤蝶呤"。此外,还提到了一种用于定量测定诊断剂的物质以及诊断剂的检测和纯化方法。本诊断剂比已知的癌症指标更具特异性,可以在任何体液,特别是尿液中进行微量常规检测。肿瘤蝶呤可以通过高压液相色谱法(HPLC)从其他蝶呤(如生物蝶呤)中分离出来。
