l -4-氯屈尿素(l -4-Cl-Kyn)是一种神经药物候选药物,目前正在开发中,用于治疗重度抑郁症。最近,在脂肽抗生素塔霉素中自然发现该氨基酸为残基。在本文中,我们报道了前所未有的转换升色氨酸到升-4-CL-的Kyn从海洋细菌糖单SP的taromycin生物合成途径催化由四种酶。CNQ-490。我们使用遗传,生化,结构和分析技术,建立升‐4‐Cl‐Kyn生物合成,由黄素依赖性色氨酸氯化酶Tar14及其黄素还原酶伴侣Tar15引发。这项工作揭示了第一种对氯化物底物具有选择性的色氨酸2,3-二加氧酶(Tar13)和犬尿氨酸甲酰胺酶(Tar16)酶。检查了Tar13,Tar14和Tar16的底物范围,并发现了令人感兴趣的混杂性,从而为这些酶作为有用的生物催化剂的目标工程打开了大门。
Using a solution-phase parallel synthesis strategy, a series of non-peptide somatostatin analogues were prepared, and their binding affinities to the five human somatostatin receptor subtypes (sst(1-5)) were determined. Imidazolyl derivatives 2 were found to bind with moderate affinity but with high selectivity to the sst(3) receptor subtype. Further modifications of these structures led to a more
