Messenger RNA (mRNA) shows high therapeutic potential, though effective delivery systems are still needed for boosting its application. Nanocarriers loading mRNA via polyion complexation with block catiomers into core-shell micellar structures are promising systems for enhancing mRNA delivery. Engineering the

Amination of guanosine (Guo) with 2,4-dinitrophenoxyamine in aqueous DMF gave 7-amino-Guo, which was readily converted to 8,5'-O-cyclo-Guo, and 8-hydroxy-Guo. Deoxyguanosine (dG) gave only deglycosylated 7-amino-G under the same reaction condition. Aminations of Guo and dG with hydroxylamine-O-sulfonic acid above pH

2-Nitropropane (2-NP), a widely used industrial solvent, is carcinogenic to rats. To clarify the mechanism of carcinogenesis by 2-NP, we investigated DNA damage by 2-NP metabolites, N-isopropylhydroxylamine (IPHA) and hydroxylamine-O-sulfonic acid (HAS), using 32P-5'-end-labelled DNA fragments obtained from genes that
