Some newer benzamide analogues of N-benzothiazol-2-yl were prepared and assessed for human glucokinase (GK) activation accompanied by molecular docking investigations for predicting the bonding connections of the these derivatives with residues in the allosteric site of GK. Among the derivatives synthesized, 6 and 7 strongly increased the catalytic action of GK (GK activation fold about 2.0 compared to control) in vitro. The outcomes of in vitro assay were supported by the molecular docking investigations of these analogues with allosteric site residues of the GK protein. Derivatives investigated in the present study can afford few lead compounds for the discovery of harmless and strong allosteric GK activating compounds for the management of type 2 diabetes.
