Allosteric activators of human glucokinase (GK) had revealed significant hypoglycemic effects for therapy of type-2 diabetes (T2D) in animal as well as human models. Some newer N-benzimidazol-2yl substituted benzamide analogues were prepared and assessed for activation of GK accompanied by molecular docking investigations for predicting the bonding interactions of these derivatives with the residues in allosteric site of GK protein. Amongst the derivatives synthesized, compounds 2 and 7 strongly increased catalytic action of GK (GK activation fold >2.0 in comparison to control) in vitro. The results of in-vitro testing were supported by the molecular docking investigations of these analogues with GK protein’s allosteric site residues (showed appreciable H-bond interactions with Arg63 residue of GK). Derivatives investigated in present study afforded few lead compounds for the discovery of harmless and strong allosteric GK activating compounds for treating T2D.

The invention discloses a synthesis method of belinostat. The method comprises the following steps: by using benzoic acid as an initial material, performing six reaction steps of chlorosulfonation, aniline condensation, reduction, oxidation, Witting-Horner condensation and hydrolysis, acylating chlorination and hydroxylamine condensation to prepare a target compound. The initial material benzoic acid of the method is cheap and easy to obtain, the sulfonylation and acylating chlorination reaction are realized through one step, the preparation time is shortened, and the yield is improved. In the oxidation process, an oxidizing reagent which is cheap and does not contains metal ion is adopted so that the active ingredients easily achieve the requirement of heavy metal ion limitation, and the pollution to the environment is reduced. All reaction intermediates of the method are solid and can be purified through a salt formation or recrystallization method, the time-consuming and labor-consuming column chromatography purification is avoided, and the method is suitable for industrial production.

Background: Glucokinase activators (GKAs) are the new class of candidate drugs which act on glucokinase (GK) enzyme and show their hypoglycaemic activity. Objective: The present work was planned to synthesize and evaluate the antidiabetic activity of a series of newer benzamide derivatives as potential GKAs. Method: This work involved synthesis of newer benzamide derivatives from benzoic acid and their evaluation by docking studies to determine the binding interactions for the best fit conformations in the binding site of GK enzyme. Based on the results of docking studies, the selected molecules were tested for their antidiabetic activity in the animal model. Results: Amongst the synthesized molecules, compounds 14 and 20 with phenyl-substituted thiazole moiety on amide nitrogen, exhibited highest activity in vivo. The results of the in vivo antidiabetic studies were found to be consistent with those of docking studies. Conclusion: These newly synthesized molecules thus can be treated as the initial hits for the development of new, safe, effective and orally bioavailable GKAs as therapeutic agents for the treatment of diabetic disorders.
