Aspartatetranscarbamylase 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

investigational tools. We synthesised 5-PCF2Am-InsP5 (1), a novel fluorinated phosphonate analogue of 5-PP-InsP5, and obtained an X-ray crystal structure of 1 in complex with diphosphoinositol pentakisphosphate kinase 2 (PPIP5K2). 5-PCF2Am-InsP5 binds to the kinase domain of PPIP5K2 in a similar orientation to that of the natural substrate 5-PP-InsP5 and the PCF2Am structure can mimic many aspects of

The syntheses of compounds 8–10 are described; the compounds showed some activity as inhibitors of HIV reverse transcriptase (IC50 365 µM).
This invention relates to halogenated derivatives of certain phosphonates having the ability to inhibit aspartate transcarbamylase and therefore are useful in the treatment of certain cancers.
These derivatives are the compounds of the formula :
or a pharmaceutically acceptable salt thereof, wherein
Z is NH or CH₂, Q is O and when Z is CH₂, Q is also (H, OH),
X is H, F or Cl and Y is F or Cl,
R₁ and R₂ each are H or C₁₋₆ alkyl, and
R₃ and R₄ each are H or C₁₋₆ alkyl.
本发明涉及某些膦酸盐的卤代衍生物,它们具有抑制天冬氨酸转氨酶的能力,因此可用于治疗某些癌症。
这些衍生物为式:
或其药学上可接受的盐,其中
Z 是 NH 或 CH₂,Q 是 O,当 Z 是 CH₂ 时,Q 也是(H,OH)、
X 是 H、F 或 Cl,Y 是 F 或 Cl、
R₁ 和 R₂ 各为 H 或 C₁₋₆ 烷基,以及
R₃ 和 R₄ 各自为 H 或 C₁₋₆ 烷基。
