Synthesis of 4-Deoxy-4-Fluoro-d-Sedoheptulose: A Promising New Sugar to Apply the Principle of Metabolic Trapping. Chemistry 2023; 29:e202302277. [PMID: 37552007 PMCID: PMC10946558 DOI: 10.1002/chem.202302277] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Revised: 08/07/2023] [Accepted: 08/08/2023] [Indexed: 08/09/2023]
Abstract
Fluorinated carbohydrates are important tools for understanding the deregulation of metabolic fluxes and pathways. Fluorinating specific positions within the sugar scaffold can lead to enhanced metabolic stability and subsequent metabolic trapping in cells. This principle has, however, never been applied to study the metabolism of the rare sugars of the pentose phosphate pathway (PPP). In this study, two fluorinated derivatives of d-sedoheptulose were designed and synthesized: 4-deoxy-4-fluoro-d-sedoheptulose (4DFS) and 3-deoxy-3-fluoro-d-sedoheptulose (3DFS). Both sugars are taken up by human fibroblasts but only 4DFS is phosphorylated. Fluorination of d-sedoheptulose at C-4 effectively halts the enzymatic degradation by transaldolase and transketolase. 4DFS thus has a high potential as a new PPP imaging probe based on the principle of metabolic trapping. Therefore, the synthesis of potential radiolabeling precursors for 4DFS for future radiofluorinations with fluorine-18 is presented.

Abstract
Stimuli-responsive supramolecular receptors are important building blocks for the construction of self-assembled functional materials. We report the design and synthesis of a pH- and light-responsive 2-hydroxychalcone-β-cyclodextrin conjugate (1-Ct) and its characterization by spectroscopic and computational methods. 1-Ct follows the typical reaction network of trans-chalcone-flavylium photoswitches. Upon light irradiation, 1-Ct can be photochemically converted into the cis-chalcone/hemiketal forms (1-Cc/1-B) under neutral pH conditions or to the flavylium cation (1-AH+) at acidic pH values. This stimuli-responsive β-cyclodextrin host, 1-Ct, was found to form stronger intramolecular self-inclusion complexes (Kintra = 14) than 1-AH+ (Kintra = 3) and weaker than 1-Cc/1-B (overall Kintra = 179), allowing control over their stability and binding properties by combinations of pH and light stimuli.

Abstract
The first total synthesis of the trimethyl ester of kadcoccinic acid A is described. The central structural element of our synthesis is a cyclopentenone motif that allows the assembly of the natural product skeleton. A gold(I)-catalyzed cyclization of an enynyl acetate led to efficient construction of the cyclopentenone scaffold. In this step, optimization studies revealed that the stereochemistry of the enynyl acetate dictates regioisomeric cyclopentenone formation. The synthesis further highlights an efficient copper-mediated conjugate addition, merged with a gold(I)-catalyzed Conia-ene reaction to connect the two fragments, thereby forging the D-ring of the natural product. The synthetic strategy reported herein can provide a general platform to access the skeleton of other members of this family of natural products.

Abstract
Camptothecin analogs, as commonly used chemotherapy drugs, usually have poor water solubility which has limited their use in the clinic. In order to improve the water-solubility of camptothecin, a new dextran derivative Dex-Mal was synthesized and used in designing a dextran–camptothecin conjugate which contained a CTB-sensitive linker. This conjugate could efficiently release the therapeutic drug SN-38 in the presence of cathepsin B and the antiproliferative activity of the conjugate was similar to the approved drug Irinotecan hydrochloride. Furthermore, in the presence of dextran, the conjugate could self-assemble into nanoparticles in water, which could improve the targeting ability through the EPR effect. This provides a potential way to formulate a drug delivery system for camptothecin analogs or other drugs which have poor water solubility. In this study, we developed the maleimidiation of dextran and applied it in a camptothecin drug delivery system.![]()

Abstract
![]()
A novel
synthetic methodology, employing a combination of the strain-promoted
azide–alkyne cycloaddition and maleimide–thiol reactions,
for the preparation of permethylated β-cyclodextrin-linker-peptidyl
conjugates is reported. Two different bifunctional maleimide cross-linking
probes, the polyethylene glycol containing hydrophilic linker bicyclo[6.1.0]
nonyne-maleimide and the hydrophobic 5′-dibenzoazacyclooctyne-maleimide,
were attached to azide-appended permethylated β-cyclodextrin. The successfully introduced maleimide function was
exploited to covalently graft a cysteine-containing peptide (Ac-Tyr-Arg-Cys-Amide)
to produce the target conjugates. The final target compounds were
isolated in high purity after purification by isocratic preparative
reverse-phase high-performance liquid chromatography. This novel synthetic
approach is expected to give access to many different cyclodextrin–linker
peptides.
