Aspartate transcarbamylase initiates the de novo biosynthetic pathway for the production of the pyrimidine nucleotides, precursors of nucleic acids. This pathway is particularly active in rapidly growing cells and tissues. Thus, this enzyme has been tested as a potential target for antiproliferative drugs. In the present work, on the basis of its structural and mechanistic properties, a series of substrate
天冬氨酸转氨酶起始了从头开始的生物合成途径,以产生嘧啶核苷酸,核酸的前体。该途径在迅速生长的细胞和组织中特别活跃。因此,已经将该酶作为抗增殖药的潜在靶标进行了测试。在目前的工作中,基于其结构和力学性能,合成了一系列底物类似物,包括潜在的自杀性假底物,并使用大肠杆菌天冬氨酸转氨酶作为模型测试了其假定的抑制作用。这些化合物中的两种似乎是该酶的非常有效的抑制剂。
