Evaluation of the thiazole Schiff bases as $$\upbeta $$β-glucuronidase inhibitors and their in silico studies
Molecular modeling indicates that three factors: substituent R, lone pair on the nitrogen of azomethine part, and the interactions made by the main skeleton of the molecule, determined the enzyme inhibitory potential of these compounds.
