[18F]-5-Fluoro-5-deoxyribose, an efficient peptide bioconjugation ligand for positron emission tomography (PET) imaging

[18F]-5-Fluoro-5-deoxyribose ([18F]-FDR) conjugates much more rapidly than [18F]-FDG under mild reaction conditions to peptides and offers new prospects for mild and rapid bioconjugation for fluorine-18 labelling in PET imaging.

A facile ultrasound-assisted synthesis of methyl 2,3-O-isopropylidene-β-D-ribofuranoside from D-ribose and its use to prepare new 1,2,3-triazole glycoconjugates

The conversion of D-ribose into its 2,3-O-isopropylidene derivative using ultrasonic irradiation is described. The ultrasound proved to be an excellent alternative as the energy source for the reaction. Different reaction times were investigated, and shorter reaction times and high yield were achieved without the need for purification of the acetonide. The compound was then applied as the starting material in the synthesis of 23 new glycoconjugates of 1,2,3-triazole that are tethered together in different ways. The synthesized compounds were characterized by FTIR, 1H NMR, 13C NMR, and HRMS techniques.

Structure-property relationships of ribose based ionic liquids

The authors of this work have successfully synthesized a broad choice of new ribose based ionic liquids, using several varying protecting groups (methyl, ethyl, allyl and benzyl) at the various positions of the carbohydrate, as well as different quarternised N-heterocycles and different anions. These consistent variations of the carbohydrate based ionic liquids (CHILs) enabled an extensive structure-property relationship study of thermal properties, allowing the authors to prove existing trends and to find a correlation between the decomposition temperature and the structure of the CHILs.

Synthesis and biological evaluation of benzo[f]indole-4,9-diones n-linked to carbohydrate chains as new type of antitumor agents

In this work, we report the synthesis of three series of carbohydrate-based benzo[f]indole-4,9-diones and amino-1,4-naphthoquinone derivatives and evaluated their cytotoxic activity against eight human cancer cell lines. Several compounds showed a promising cytotoxic activity toward the tumor cell lines (half maximal inhibitory concentration (IC50) 10.0 μM). The importance of the substitution pattern of the quinone derivatives on the antitumor activity was also discussed. 3-Carboethoxy-2-methyl-benzo[f]indole-4,9-dione derivatives were more cytotoxic than their parent compounds and amino-1,4-naphthoquinones. Unlike clinically useful anticancer agent doxorubicin, the majority of synthesized compounds did not exhibit any lytic effects against erythrocytes or normal human leukocytes.

New glycosylated platinum(II) phthalocyanine containing ribose moiety – synthesis and photophysical properties

The synthesis and spectral characterisation of new glycoconjugated phthalonitrile connected with triazole linker via Cu(II)-mediated click reaction is reported. Treatment of azido derivative of 1-methoxy-2,3- O-isopropylidene-β-D-ribose with 4-O-propargyloxy-substituted phthalonitrile in presence copper(II) sulfate pentahydrate and sodium L-ascorbate in tert-butanol/water gave desired glycophthalonitrile with 84% yield. This precursor underwent mixed-cyclisation with the tert-butyl-substituted phthalonitrile, to afford the mono-glycosylated A3B-type platinum(II) phthalocyanine. Upon irradiation this compound could sensitise the formation of singlet oxygen in acetone, with 0.95 quantum yield by comparative method with use of 1,3-diphenylisobenzofuran (DPBF) as scavenger.
