Zur Temperaturabhängigkeit der pH-Abhängigkeit enzymatischer Modellreaktionen
The temperature dependence of the pH-dependence of the hydrolysis of p-nitrophenylacetate catalyzed by 4(β-hydroxyethyl)-imidazole, imidazole-propionic acid, cis- and trans-urocanic acid, mercaptoethanole, cysteamine and mercaptomethyl-imidazole was ...

Syntheses of polyalkylated imidazoles
We have developed improved general simple methods for large-scale preparation of polyalkylated imidazoles by improved multicomponent synthesis from commercially available starting materials. A large range of NH- and N-alkyl-polyalkylimidazoles (40 in total, including novel compounds) has been synthesized.

Solution-phase synthesis of pyrrole-imidazole polyamides [PDF]
Pyrrole−imidazole polyamides are DNA-binding molecules that are programmable for a large repertoire of DNA sequences. Typical syntheses of this class of heterocyclic oligomers rely on solid-phase methods. Solid-phase methodologies offer rapid assembly on

Structural Basis for EGFR Mutant Inhibition by Trisubstituted Imidazole Inhibitors.
Acquired drug resistance in epidermal growth factor receptor (EGFR) mutant non-small cell lung cancer is a persistent challenge in cancer therapy. Previous studies of trisubstituted imidazole inhibitors lead to the serendipitous discovery of inhibitors ...

Dual role of imidazole as activator/inhibitor of sweet almond (Prunus dulcis) β-glucosidase
The activity of Prunus dulcis (sweet almond) β-glucosidase at the expense of p-nitrophenyl-β-d-glucopyranoside at pH 6 was determined, both under steady-state and pre-steady-state conditions. Using crude enzyme preparations, competitive inhibition by 1–5
