α-Glucosidase is responsible for glucose release of oligosaccharides and disaccharides in the intestine and increase postprandial hyperglycemia. Inhibition of this enzyme is a beneficial therapeutic method for glycemic control in diabetes. This study deals with the design and synthesis of 4,5-diphenylimidazole-N-phenylacetamide derivatives 7a–l and the screen of these compounds for their potential for α-glucosidase inhibition. All the synthesized compounds exhibited superior α-glucosidase inhibition (IC50 = 90.0–598.5 μM) as compared to standard inhibitor acarbose (IC50 = 750.0 μM). In contrast, these compounds were inactive against α-amylase. Among the synthesized compounds, compound 7h was the most potent inhibitor of this library and was a competitive inhibitor into α-glucosidase with Ki value = 86.3 μM. Docking study of the most potent compounds was performed to evaluate the binding interactions of these compounds with the active site of enzyme and to determine of binding energies of ligand–enzyme complexes. The results of this in silico study are in complete agreement with the results obtained from in vitro α-glucosidase inhibition assay. Docking study of the most potent compound demonstrated that it interacted with important residues in the active site of α-glucosidase. In vitro cytotoxic activity of the most potent compounds and in silico druglikeness/ADME/toxicity study of these compounds were evaluated.

Twenty-two compounds based on thiazolidine-2,4-dione moiety were synthesized and evaluated for the inhibitory potency on the production of nitric oxide (NO), inducible nitric oxide synthase (iNOS) activity, and the generation of prostaglandin E2 (PEG2). (Z)-N-(3-Chlorophenyl)-2-(4- ((2,4-dioxothiazolidin-5-ylidene) methyl) phenoxy) acetamide (3I), superior to the commercial anti-inflammatory drug indomethacin, significantly inhibited iNOS activity (IC50 = 8.66 μM), iNOS-mediated NO, and cyclooxygenase (COX)-2-derived PGE2 production (IC50 = 4.16 and 23.55 μM, respectively) on lipopolysaccharide (LPS)-induced RAW 264.7 cells. Docking study revealed that 3I was perfectly docking into the active site of murine iNOS and suppressed the expression of iNOS protein as evidenced by Western blot analysis. At the dose of 50 mg/kg, oral administration of 3I possessed protective properties in both carrageenan-induced paw edema and adjuvant-induced arthritis rat models.

In order to identify a high-affinity, selective antagonist for the A2B subtype adenosine receptor, more than 40 1,8-disubstituted-3-(3-methoxypropyl) xanthines were prepared and evaluated for their binding affinity at recombinant human adenosin
