A novel compound, 1',2'-diacyl-(6R,S)-5,6,7,8-tetrahydro-L-biopterin which is prepared by catalytical hydrogenation of a 1',2'-diacyl-L-biopterin in a solvent in the presence of a catalyst. The 1',2'-diacyl-L-biopterin is prepared from a 1,1-dialkylsulfonyl-L- rhamnose through an acyl derivative of 5-deoxy-L-arabinose and a hydrazine derivative of tetrahydro-L-biopterin without isolating the intermediate products. The 1',2'-diacyl-(6R,S)-5,6,7,8-tetrahydro-L-biopterin can be used for treatment of atypical phenylketonuria or dihydropterin-reductase deficiency and can readily cross the blood brain barrier without neurotransmitter precursors.
一种新型化合物--1',2'-二乙酰基-(6R,S)-5,6,7,8-四氢-L-生物蝶呤,是在催化剂存在下,在溶剂中通过催化氢化 1',2'-二乙酰基-L-生物蝶呤而制备的。1',2'-二乙酰基-L-生物蝶呤由 1,1-二烷基磺酰基-L-鼠李糖通过 5-脱氧-L-阿拉伯糖的酰基衍生物和四氢-L-生物蝶呤的肼衍生物制备而成,中间产物无需分离。这种 1',2'-二乙酰基-(6R,S)-5,6,7,8-四氢-L-生物蝶呤可用于治疗非典型苯丙酮尿症或二氢蝶呤还原酶缺乏症,并且不含神经递质前体,可轻易通过血脑屏障。
