  Dihydropyrano [2,3-c] pyrazole: Novel in vitro inhibitors of yeast α-glucosidase

  摘要：

  Inhibition of alpha-glucosidase enzyme activity is a reliable approach towards controlling post-prandial hyperglycemia associated risk factors. During the current study, a series of dihydropyrano[ 2,3-c] pyrazoles (1-35) were synthesized and evaluated for their a-glucosidase inhibitory activity. Compounds 1, 4, 22, 30, and 33 were found to be the potent inhibitors of the yeast alpha-glucosidase enzyme. Mechanistic studies on most potent compounds reveled that 1, 4, and 30 were non-competitive inhibitors (K-i = 9.75 +/- 0.07, 46 +/- 0.0001, and 69.16 +/- 0.01 mu M, respectively), compound 22 is a competitive inhibitor (K-i = 190 +/- 0.016 mu M), while 33 was an uncompetitive inhibitor (K-i = 45 +/- 0.0014 mu M) of the enzyme. Finally, the cytotoxicity of potent compounds (i.e. compounds 1, 4, 22, 30, and 33) was also evaluated against mouse fibroblast 3T3 cell line assay, and no toxicity was observed. This study identifies non-cytotoxic novel inhibitors of alpha-glucosidase enzyme for further investigation as anti-diabetic agents. (C) 2016 Elsevier Inc. All rights reserved.

  A new convenient method for the synthesis of 6-amino-2H,4H-pyrano[2,3-c]pyrazole-5-carbonitriles, namely, four-component condensation of carbonyl compounds (aromatic aldehydes, heterocyclic ketones), malononitrile, β-keto esters, and hydrazine hydrate in ethanol in the presence of triethylamine as a catalyst, which occurs selectively, is developed. One-pot two-step modification of this method is proposed
