Biology-oriented drug synthesis (BIODS), in vitro urease inhibitory activity, and in silico studies on ibuprofen derivatives

Novel ibuprofen derivatives 1 – 19 including ibuprofen hydrazide 1 , and substituted thiourea derivatives 2 – 19 were synthesized and characterized by EI-MS, FAB-MS, HREI-MS, HRFAB-MS, 1 H-, and 13 C-NMR spectroscopic techniques. The synthetic molecules 1 – 19 were examined for their in vitro urease...

Description
Summary:Novel ibuprofen derivatives 1 – 19 including ibuprofen hydrazide 1 , and substituted thiourea derivatives 2 – 19 were synthesized and characterized by EI-MS, FAB-MS, HREI-MS, HRFAB-MS, 1 H-, and 13 C-NMR spectroscopic techniques. The synthetic molecules 1 – 19 were examined for their in vitro urease inhibition and were found to display a diversified degree of inhibitory potential in the range of IC 50  = 2.96–178 μM as compared to the standard thiourea (IC 50  = 21.32 ± 0.22 μM). Out of nineteen, thirteen derivatives 2 – 4 , 6 , 7 , 9 , 11 – 15 , 17 , and 18 demonstrated remarkable inhibitory activity with IC 50 values of 2.96 ± 1.11 to 16.1 ± 1.07 μM, compound 5 exhibited moderate inhibition with IC 50 value of 37.3 ± 0.41 μM, whereas, compounds 1 , 8 , and 10 demonstrated weak inhibition against urease enzyme. Almost all structural features are participating in the activity; however, limited structure–activity relationship was discussed on the basis of different structural features, i.e., different functional groups and their positions at aryl part. In addition, molecular docking study was performed in order to understand the ligands binding interactions with the active site of urease enzyme. Graphic abstract
