Synthesis of new 1,2,4-triazole derivatives and investigation of their matrix metalloproteinase-9 (Mmp-9) inhibition properties

Abstract

Nine new 2-[[5-((4-acetamidophenoxy)methyl)-4-phenyl-4H-1,2,4-triazol-3-yl] thio]-N-(aryl/heteroaryl)acetamide (5a-5i) derivatives were synthesized and tested for their matrix metalloproteinase-9 (MMP-9) inhibition potency which is associated with antiproliferative activity. None of the compounds exhibited MMP-9 inhibition activity close to standard drug however, two compounds 5e bearing 6-methylbenzo-thiazole and 5g bearing 6-ethoxybenzothiazole moieties showed the highest MMP-9 inhibition which were determined over than 50% percentage at 100 µg/mL concen-tration. Some physicochemical properties of all final compounds were calculated via SwissADME and the results were modest to be able to an oral drug. Molecular docking studies were realized with MMP-9 enzyme (PDB ID: 5I12) and 5d, 5e, and 5g compounds for comparing the active and non-active/low effective structures. © 2021, İstanbul Medipol University.
