3′-Amino modifications enhance the antifungal properties of N 4 -alkyl-5-methylcytidines for potential biocides

Liudmila A. Alexandrova, Oleg Shevchenko, Maxim V. Jasko, Pavel N. Solyev et autres

A set of 3′-modified N 4 -alkyl-5-methyl-2′-deoxycytidines has been synthesized and evaluated for biological activity. The replacement of the 3′-hydroxyl group with amino, aminoethyl and dialkylamino groups significantly enhances antifungal activity.

DNA-Templated Fluorescent Silver Nanoclusters Inhibit Bacterial Growth While Being Non-Toxic to Mammalian Cells

Lewis A. Rolband, Liam Yourston, Morgan Chandler, Damian Beasock et autres

Silver has a long history of antibacterial effectiveness. The combination of atomically precise metal nanoclusters with the field of nucleic acid nanotechnology has given rise to DNA-templated silver nanoclusters (DNA-AgNCs) which can be engineered with reproducible and unique fluorescent properties and antibacterial …

Short-Period undulators with electrostatic field

Н.А. Винокуров, Oleg Shevchenko

Due to strong sextupole corrections, the vertical dynamic aperture of a low-emittance storage ring is rather small. Therefore, in-vacuum short-period undulators can provide a sufficiently high field. In particular, a significant electrostatic field value can be obtained near electrodes. To eliminate the …
