Current study is based on the biology-oriented drug synthesis (BIODS) of 2-(2-methyl-5-nitro-1H-imidazol-1-yl)ethyl aryl carboxylate derivatives 1–26, by treating metronidazole with different aryl and hetero-aryl carboxylic acids in the presence of 1,1'-carbonyl diimidazole (CDI) as a coupling agent. Structures of all synthetic derivatives were confirmed with the help of various spectroscopic techniques such as EI-MS,1H -NMR and13C NMR. CHN elemental analyses were also found in agreement with the calculated values. Synthetic derivatives were evaluated to check their β-glucuronidase inhibitory activity which revealed that except few derivatives, all demonstrated good inhibition in the range of IC50= 1.20 ± 0.01–60.30 ± 1.40 μM as compared to the standard D-saccharic acid 1,4-lactone (IC50= 48.38 ± 1.05 μM). Compounds 1, 3, 4, 6, 9–19, and 21–24 were found to be potent analogs and showed superior activity than standard. Limited structure-activity relationship is suggested that the molecules having electron withdrawing groups like NO2, F, Cl, and Br, were displayed better activity than the compounds with electron donating groups such as Me, OMe and BuO. To verify these interpretations, in silico study was also performed, a good correlation was observed between bioactivities and docking studies.

A series of metronidazole ester derivatives 1-34 has been synthesized with the aim of developing new leads with antiglycation activity. The in vitro evaluation of antiglycation potential of 1-34 showed that the ester derivatives 28, 16, and 3 have IC50 values 218.97 ± 2.5, 245.3 ± 5.1, and 278.6 ± 0.8 μM, respectively, comparable to the standard agent, rutin (IC50 = 294.5 ± 1.50 μM). The study identifies a new class of potent antiglycation agents. A structure-activity relationship has also been evaluated. All the compounds were characterized by using spectroscopic techniques, including 1H NMR, IR, and EI-MS.
