Sialic Acid 4‐N‐Piperazine and Piperidine Derivatives Bind with High Affinity to the P. mirabilis Sialic Acid Sodium Solute Symporter

ChemMedChem, Volume 17, Issue 23, December 5, 2022., 2022
A new target: Bacterial sialic acid uptake inhibition is a promising strategy for the development of antibacterial drugs. In this study, we present the design, synthesis and evaluation of sialic acid 4‐piperidine and piperazine derivatives a novel compound class, which bind the SiaT from Proteus mirabilis and target a different portion of the binding ...

Prodrugs of the Archetypal Dynamin Inhibitor Bis‐T‐22

ChemMedChem, Volume 17, Issue 24, December 16, 2022., 2022
The Bis‐T series of compounds comprise some of the most potent inhibitors of dynamin GTPase activity yet reported, such as Bis‐T‐22 (2). The catechol moieties are believed to limit cell permeability, rendering these compounds largely inactive in cells.

Excited‐State Basicity Diverts the Site‐Selectivity of Aromatic Deuteration: Application to the Late‐Stage Labeling of Pharmaceuticals

Angewandte Chemie International Edition, EarlyView.
We present a metal‐free method for aromatic deuterium labeling via photoexcitation in deuterated HFIP. This approach leverages the enhanced basicity of excited‐state aromatics to achieve selective hydrogen isotope exchange at challenging positions. Demonstrated on complex drug molecules, this efficient strategy provides a valuable tool for isotope ...

The Chemerin Receptor CMKLR1 Requires Full‐Length Chemerin for High Affinity in Contrast to GPR1 as Demonstrated by a New Nanoluciferase‐Based Binding Assay

ChemMedChem, Volume 17, Issue 23, December 5, 2022., 2022
The adipokine chemerin and the short peptide agonist chemerin‐9 activate two GPCRs: CMKLR1 and GPR1. Here, we established a nanoluciferase based binding assay to analyze differences in ligand binding. For GPR1, both ligands show high affinity and comparable binding.

SYNTHESIS AND CATECHOLASE ACTIVITY OF Cu(II) AND Fe(III) COMPLEXES OF 4-METHYL-2-((PIPERIDIN-1-YL)METHYL)PHENOL

Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2020
This study is aimed at evaluating the impact of N- and S- bonding modes of thiocyanate substituent on catecholase activity as its presence in the coordination sphere of the metal complex can either reduce catecholase activity or otherwise. 4-Methyl-2-(
