UMPS_HUMAN Defects in UMPS are the cause of orotic aciduria type 1 (ORAC1) [MIM:258900. A disorder of pyrimidine metabolism resulting in megaloblastic anemia and orotic acid crystalluria that is frequently associated with some degree of physical and mental retardation. A minority of cases have additional features, particularly congenital malformations and immune deficiencies.[1]

Publication Abstract from PubMed
Fluorinated nucleosides and nucleotides are of considerable interest to medicinal chemists because of their antiviral, anticancer, and other biological activities. However, their direct interactions at target binding sites are not well understood. A new class of 2'-deoxy-2'-fluoro-C6-substituted uridine and UMP derivatives were synthesized and evaluated as inhibitors of orotidine 5'-monophosphate decarboxylase (ODCase or OMPDCase). These compounds were synthesized from the key intermediate, fully protected 2'-deoxy-2'-fluorouridine. Among the synthesized compounds, 2'-deoxy-2'-fluoro-6-iodo-UMP covalently inhibited human ODCase with a second-order rate constant of 0.62 +/- 0.02 M(-1) s(-1). Interestingly, the 6-cyano-2'-fluoro derivative covalently interacted with ODCase defying the conventional thinking, where its ribosyl derivative undergoes transformation into BMP by ODCase. This confirms that the 2'-fluoro moiety influences the chemistry at the C6 position of the nucleotides and thus interactions in the active site of ODCase. Molecular interactions of the 2'-fluorinated nucleotides are compared to those with the 3'-fluorinated nucleotides bound to the corresponding target enzyme, and the carbohydrate moieties were shown to bind in different conformations.
