A new chloronium-containing salt, [Me Cl][Al(OTeF ) ], was synthesized on multigram scale by means of a simple one-pot procedure. The isolated product can be handled at room temperature and used as a strong electrophilic methylation agent. This is demonstrated by the methylation of the very weak bases P(CF ) , PF , MeI, and MeBr.

: Orally disintegrating film (ODF) is prepared using water-soluble polymers as film-forming agents. To improve mechanical and disintegration properties, some polymers need to be blended with others. This study aimed to investigate the utility of hydroxypropyl cellulose (HPC) and hydroxypropyl methyl cellulose (HPMC) as blend film-forming components for ODFs.

Background: In the era of resistance, the design and search for new "small" molecules with a narrow spectrum of activity that target a protein or enzyme specific to a certain bacterium with high selectivity and minimal side effects remains an urgent problem of medicinal chemistry. In this regard, we developed and successfully implemented a strategy for the search for new hybrid molecules, namely, the not broadly known [2-(3-R-1-[1,2,4]-triazol-5-yl)phenyl]amines. They can act as "building blocks" and allow for the introduction of certain structural motifs into the desired final products in order to enhance the antistaphylococcal effect.

In recent years, a number of synthetic potentiators of antibiotics have been discovered. Their action can significantly enhance the antibacterial effect and limit the spread of antibiotic resistance through inhibition of bacterial cystathionine-γ-lyase. To expand the known set of potentiators, we developed methods for the synthesis of five new representatives of 6-bromoindole derivatives-potential inhibitors of bacterial cystathionine-γ-lyase-namely potassium 3-amino-5-((6-bromoindolyl)methyl)thiophene-2-carboxylate () and its 6-bromoindazole analogs ( and ), along with two 6-broindazole analogs of the parent compound .

Epigenetic abnormalities play a critical role in colon carcinogenesis, making them a promising target for therapeutic interventions. In this study, we demonstrated that curcumin reduces colon cancer cell survival and that a decrease in lysine methylation was involved in such an effect. This correlated with the downregulation of methyltransferases EZH2, MLL1, and G9a, in both wild-type p53 (wtp53) HCT116 cells and mutant p53 (mutp53) SW480 cells, as well as SET7/9 specifically in wtp53 HCT116 cells.
