Population Pharmacokinetics of Intracellular 5-Fluorouridine 5'-Triphosphate and its Relationship with Hand-and-Foot Syndrome in Patients Treated with Capecitabine
AAPS J 2021 Jan 8;23(1):23.PMID:33417061DOI:10.1208/s12248-020-00533-1.
Capecitabine is an oral pro-drug of 5-fluorouracil. Patients with solid tumours who are treated with capecitabine may develop hand-and-foot syndrome (HFS) as side effect. This might be a result of accumulation of intracellular metabolites. We characterised the pharmacokinetics (PK) of 5-Fluorouridine 5'-triphosphate (FUTP) in peripheral blood mononuclear cells (PBMCs) and assessed the relationship between exposure to capecitabine or its metabolites and the development of HFS. Plasma and intracellular capecitabine PK data and ordered categorical HFS data was available. A previously developed model describing the PK of capecitabine and metabolites was extended to describe the intracellular FUTP concentrations. Subsequently, a continuous-time Markov model was developed to describe the development of HFS during treatment with capecitabine. The influences of capecitabine and metabolite concentrations on the development of HFS were evaluated. The PK of intracellular FUTP was described by an one-compartment model with first-order elimination (ke,FUTP was 0.028 h-1 (95% confidence interval 0.022-0.039)) where the FUTP influx rate was proportional to the 5-FU plasma concentrations. The predicted individual intracellular FUTP concentration was identified as a significant predictor for the development and severity of HFS. Simulations demonstrated a clear exposure-response relationship. The intracellular FUTP concentrations were successfully described and a significant relationship between these intracellular concentrations and the development and severity of HFS was identified. This model can be used to simulate future dosing regimens and thereby optimise treatment with capecitabine.
Determination of 5-fluorocytosine, 5-fluorouracil, and 5-Fluorouridine in hospital wastewater by liquid chromatography-mass spectrometry
J Sep Sci 2020 Aug;43(15):3074-3082.PMID:32432394DOI:10.1002/jssc.202000144.
Chemotherapeutics are pharmaceutical compounds the occurrence of which in the environment is of growing concern because of the increase in treatments against cancer diseases. They can reach the aquatic ecosystems after passing through wastewater treatment plants without complete removal. One of the most frequently used chemotherapeutics is 5-fluorouracil which exhibits a strong cytostatic effect. In this paper, an analytical methodology was developed, validated, and applied to determine 5-fluorouracil, its precursor, 5-fluorocytosine, and its major active metabolite, 5-Fluorouridine, in hospital wastewater samples. Due to the expected low concentrations after dilution and interferences present in such a complex matrix, a very selective and sensitive detection method is required. Moreover, an extraction method must be implemented prior to the determination in order to purify the sample extract and preconcentrate the target analytes at micrograms per liter concentration levels. Solid-phase extraction followed by liquid chromatography with tandem mass spectrometry was the combination of choice and all included parameters were studied. Under optimized conditions for wastewater samples analysis, recoveries from 63 to 108% were obtained, while intraday and interday relative standard deviations never exceeded 20 and 25%, respectively. Limits of detection between 61 and 620 ng/L were achieved. Finally, the optimized method was applied to samples from hospital wastewater effluents.
Immobilization of 5-Fluorouridine on chitosan
Chem Biodivers 2013 Oct;10(10):1828-41.PMID:24130026DOI:10.1002/cbdv.201300025.
The 2',3'-O-levulinic acid derivative 2b of the cancerostatic 5-Fluorouridine as well as its N(3)-farnesylated nucleolipid 2d were synthesized and coupled to H2 O-soluble chitosanes of different molecular weight and at various pH values (3.5-5.5) leading to 6 and 7. In addition, the coumarine fluorophore ATTO-488 N(9)-butanoate was bound to the biopolymer by a sequential-coupling technique to afford 9 and 10. Moreover, chitosan foils were prepared, to which 2b was coupled. Their degradation by chitosanase (from Streptomyces sp. N174) was studied UV-spectrophotometrically in a Franz diffusion cell.
A comparison of 5-Fluorouridine and 5-fluorouracil in an experimental model for the treatment of vitreoretinal scarring
Curr Eye Res 1993 May;12(5):397-401.PMID:8344064DOI:10.3109/02713689309024621.
5-Fluorouridine (5-FUR), a ribonucleotide metabolite of 5-Fluorouracil (5-FU), is a more potent inhibitor of cellular proliferation and cell-mediated contraction in vitro than 5-FU. We compared the efficacy of these two drugs in a cell injection model of proliferative vitreoretinopathy using New Zealand albino rabbits. Forty-five eyes were divided into three groups and injected intravitreally with homologous fibroblasts. Eyes were examined at the time of injection and 7, 14, 21 and 28 days thereafter. By day 28, 70.5% (12 of 17) of 5-FUR treated eyes demonstrated no appreciable proliferative or tractional activity compared with 41.7% (5 of 12) of 5-FU treated eyes and 10% (1 of 10) of control eyes (p < 0.006). Medullary ray puckers developed in 29.4% (5 of 17) and 25% (3 of 12) of 5-FUR and 5-FU treated eyes respectively. No 5-FUR treated eye developed extensive tractional or combined tractional and rhegmatogenous retinal detachment compared with 33.3% (4 of 12) of 5-FU treated eyes and 80% (8 of 10) of control eyes (p < 0.001). These results suggest that 5-Fluorouridine may be more effective than 5-FU for the treatment of vitreoretinal scarring.
Synthesis and biological evaluation of 6-substituted-5-fluorouridine ProTides
Bioorg Med Chem 2018 Feb 1;26(3):551-565.PMID:29277307DOI:10.1016/j.bmc.2017.11.037.
A new family of thirteen phosphoramidate prodrugs (ProTides) of different 6-substituted-5-fluorouridine nucleoside analogues were synthesized and evaluated as potential anticancer agents. In addition, antiviral activity against Chikungunya (CHIKV) virus was evaluated using a cytopathic effect inhibition assay. Although a carboxypeptidase Y assay supported a putative mechanism of activation of ProTides built on 5-Fluorouridine with such C6-modifications, the Hint docking studies revealed a compromised substrate-activity for the Hint phosphoramidase-type enzyme that is likely responsible for phosphoramidate bioactivation through P-N bond cleavage and free nucleoside 5'-monophosphate delivery. Our observations may support and explain to some extent the poor in vitro biological activity generally demonstrated by the series of 6-substituted-5-fluorouridine phosphoramidates (ProTides) and will be of guidance for the design of novel phosphoramidate prodrugs.
