Syntheses of inhibitors for the enzyme thymidine 5′-diphosphate-glucose-4,6-dehydratase (EC 4.2.1.46)
摘要:
Inhibitors of the enzyme thymidine 5'-diphosphate-glucose-4,6-dehydratase (EC 4.2.1.46) were synthesised starting from thymidine, 2-deoxy-uridine and -cytidine. The diphosphate moieties have either been replaced by methylene diphosphonate or phosphoryl hydroxyacetic acid to yield inhibitors in a similar range to thymidine 5'-diphosphate itself. Spacers were attached to various positions, of which those at C-5 of the nucleobase were suitable analogues and showed a mixed type of inhibition characteristics, whereas attachment at other sites led to marginally active or inactive inhibitors. These investigations will prepare the ground for developing a purification procedure based on affinity chromatography. (C) 1999 Elsevier Science Ltd. All rights reserved.
This paper describes the design and synthesis of a new type of aminoacyl-adenylate analogue (aa-AMPN) having an N-acyl phosphoramidate linkage where the oxygen atom of the mixed anhydride bond of aminoacyl-adenylate (aa-AMP) is replaced by an amino group. This new type of aa-AMP analogue is expected to be useful as material for studies on the recognition mechanism of the aminoacylation of tRNA and
