6-SUBSTITUTED 5-FLUOROURACIL DERIVATIVES AS TRANSITION STATE ANALOGUE INHIBITORS OF THYMIDINE PHOSPHORYLASE
@article{Kalman20056SUBSTITUTED5D, title={6-SUBSTITUTED 5-FLUOROURACIL DERIVATIVES AS TRANSITION STATE ANALOGUE INHIBITORS OF THYMIDINE PHOSPHORYLASE}, author={Thomas I. Kalman and Li Lai}, journal={Nucleosides, Nucleotides \& Nucleic Acids}, year={2005}, volume={24}, pages={367 - 373} }
A combination of mechanism-based and structure-based design strategies led to the synthesis of a series of 5- and 6-substituted uracil derivatives as potential inhibitors of thymidine phosphorlase/platelet derived endothelial cell growth factor (TP/PD-ECGF). Among those tested, 6-imidazolylmethyl-5-fluorouracil was found to be the most potent inhibitor with a Ki-value of 51 nM, representing a new class of 5-fluoropyrimidines with a novel mechanism of action.

The various structural features of the enzyme which might be responsible for the specificity for thymidine and not for uridine were identified and the presence of the 2'-hydroxyl group in uridine results in a different position of the uridine furanose moiety compared with that of Thymidine, which may be the key element of the substrate specificity.

The reaction involves the first generation of N-acyliminium ions directly from the versatile barbituric acids and proceeds with excellent stereoselectivity, thus providing a modular and highly practical sequence to the biologically significant uracil derivatives.
