Synthesis, characterization, anti-ulcer action and molecular docking evaluation of novel benzimidazole-pyrazole hybrids

A series of six novel benzimidazole-pyrazole hybrid molecules was synthesized and characterized using elemental analysis (CHN) and spectroscopic methods ((1)HNMR, FT-IR). All the synthesized compounds were evaluated for their in vivo anti ulcerogenic activity using Albino rats (weighing 180–220 g)....

Sumario:A series of six novel benzimidazole-pyrazole hybrid molecules was synthesized and characterized using elemental analysis (CHN) and spectroscopic methods ((1)HNMR, FT-IR). All the synthesized compounds were evaluated for their in vivo anti ulcerogenic activity using Albino rats (weighing 180–220 g). The interactions between the compounds and active site residues of H(+)/K(+) ATPase were investigated by molecular docking studies using autodock vina 4.0. SCH28080 was used to validate the docking results. Also the drug likeliness of these compounds was predicted using Molinspiration server in light of Lipinski’s rule of five. All the six synthesized compounds exhibited higher anti-ulcer activity as compared to omeprazole. These novel hybrid compounds showed comparable anti-ulcer potential of 72–83% at dose level of 500 µg/kg, whereas omeprazole showed 83% anti-ulcer activity at dose level of 30 mg/kg. The results clearly indicate that these novel benzimidazole-pyrazole hybrids can present a new class of potential anti ulcer agents and can serve as new anti-ulcer drugs after further investigation.
