抗瘤酮(Antineoplastons)的研究于1967年开始,最初是从人血中分离得到,后来从人尿与组织中分离。由于经济效益关系,选择人尿为提取抗瘤酮的主要来源。抗瘤酮A(Antineoplaston A)是具有广谱作用的抗瘤酮的混合物。抗瘤酮A_3为A经进一步分离而得的组份,是从人尿中分离制得的小肽与氨基酸衍生物的氧化混合物。 Antineoplastons research began in 1967, initially isolated from human blood and later isolated from human urine and tissues. Due to the economic relationship, the selection of human urine as the main source of anti-cancer ketones. Antineoplaston A is a mixture of anti-tumor ketones that have a broad spectrum of actions. Anti-tumor ketones A_3 is a component of A that is further isolated and is an oxidized mixture of small peptides and amino acid derivatives prepared from human urine.
