DNA is one of the most exciting biomolecules in nature for developing supramolecular biofunctional nanoarchitectures owing to the highly specific and selective interactions between complementary Watson-Crick base pairing. Herein, simple and one-pot synthetic procedures have been implemented for producing a library of DNA nucleobase derivatives endowed with reactive functional groups for bioconjugation and cross-linking strategies with other (bio)molecules. Purine and pyrimidine molecules have been regioselectively N?H functionalized either via N-alkylation, N-allylation, N-propargylation or Michael-type reactions and structurally characterized. The influence of the reaction conditions was assessed and discussed. The in vitro biocompatibility of the native and nucleobase derivatives was evaluated by culturing them with human fibroblasts, revealing their cytocompatibility. The library of nucleobase derivatives holds great promise for being coupled to different biomolecules, including biopolymeric materials, lipids, and peptides, thus potentially leading to modular supramolecular nanobiomaterials for biomedicine.
The Convenient Synthesis of Unsaturated Nucleoside Analogues in Water under Microwave Irradiation

A convenient method for the regioselective synthesis of unsaturated nucleoside analogs in water under microwave irradiation was developed. All pyrimidine and purine nucleoside derivatives were exclusively alkylated at N1 and N9 respectively in good to excellent yields. In addition, this system could tolerate a broad range of functional groups, such as chloro, bromo, iodo, alkyl, amino, and hydroxyl groups. More importantly, the reaction scale could be enlarged to 50 mmol which made this route attractive for industrial application.
A new 9-alkyladenine-cyclic methylglyoxal diadduct activates wt- and F508del-cystic fibrosis transmembrane conductance regulator (CFTR) in vitro and in vivo

Cystic fibrosis transmembrane conductance regulator (CFTR) is the main chloride channel present in the apical membrane of epithelial cells and the F508 deletion (F508del-CFTR) in the CF gene is the most common cystic fibrosis-causing mutation. In the sear
