    摘要:
    在有氧条件下,对大鼠各种器官的亚细胞分离物中的L-苯丙氨酸进行了氢氧化反应的研究。L-苯丙氨酸在雄性大鼠的肝脏、肾脏、大脑和肾上腺的2000×g匀浆中转化为p-、m-和o-酪氨酸。通过高效液相色谱法测定了培养混合物中的这三种代谢产物。该氢氧化反应仅在上述器官的后微粒体部分发生,而在微粒体分离物中没有发生,并且需要一种嘌呤类化合物作为辅助因子。添加p-氯苯丙氨酸和α-甲基酪氨酸,这两种分别是苯丙氨酸羟化酶和酪氨酸羟化酶的特异性抑制剂,抑制了苯丙氨酸的氢氧化反应。另一方面,已知超氧化物歧化酶和碘化钾是超氧自由基和羟基自由基的清除剂,但对氢氧化反应没有显著影响。这些结果表明,苯丙氨酸转化为m-和o-酪氨酸主要是由苯丙氨酸羟化酶和酪氨酸羟化酶引起的。

  • Effects of Tetrahydropterines on the Generation of Quinones Catalyzed by Tyrosinase
    作者:Francis GARCIA-MOLINA、Joseph Louis MUNOZ-MUNOZ、Francis MARTINEZ-ORTIZ、Joseph TUDELA、Francis GARCÍA-CÁNOVAS、Joseph Neptune RODRIGUEZ-LOPEZ
    DOI:10.1271/bbb.90924
    日期:2010.5.23
    Tetrahydrobiopterine (6BH4) can diminish the oxidative stress undergone by keratinocytes and melanocytes by reducing the o-quinones generated by the oxidation of the corresponding o-diphenols. We found that 6BH4 and their analogs reduced all the o-quinones studied. The formal potentials of different quinone/diphenol pairs indicate that the o-quinones with withdrawing groups are more potent oxidants than those with donating groups.
    四氢生物蝶呤(6BH4)可以通过减少相应的邻二酚氧化产生的邻醌来减轻角质细胞和黑色素细胞所承受的氧化压力。我们发现,6BH4 及其类似物可以还原所研究的所有邻醌类化合物。不同醌/二酚对的形式电位表明,具有抽离基团的邻醌比具有捐赠基团的邻醌具有更强的氧化作用。

    Disclosed are a dopaminergic neuron-like cell cluster exhibiting a far higher level of a dopaminergic neuron marker, compared to conventional 2D or 3D cultured cells, and a method for preparing the same. The cell cluster can be more effectively differentiated into dopaminergic neurons in the presence of a differentiation-inducing factor, so that it is suitable for use in studying neurodegenerative diseases such as Parkinson's disease. In addition, the cell cluster can express factors reinforcing intercellular interaction at an improved level, and is free of cellular toxicity and safe to the body, easy to culture with high productivity, superior in biocompatibility, and highly unlikely to undergo mutations. Also provided is a dish for culturing a 3D dopaminergic neuron-like cell cluster on a mass scale; which guarantees the 3D dopaminergic neuron-like cell cluster superior biocompatibility, freedom of cellular toxicity, minimal mutagenicity, and improvement in the expression of factors reinforcing intercellular interaction.
