ALDOSE REDUCTASE (ALDITOL: NADP oxidoreductase, EC 1.1.1.21) is the enzyme responsible for the conversion of glucose to its sugar alcohol, sorbitol. In this study, aldose reductase and a closely related enzyme, L-hexonate dehydrogenase (L-gulonate: NADP oxidoreductase, EC 1.1.1.19), were purified from rat pancreas. Glutaric acid, 2,4-dimethyl glutaric acid, 3,3-tetramethylene glutaric acid, and...

Blood sugar levels of normal rats treated with D-400 showed significant reduction (P < 0.05) as compared to control groups. The fall was seen at one month and remained so uptill 3 months. Hyperglycemic response to adrenaline was significantly lowered (P < 0.05) following D-400 treatment. D-400 potentiated the hypoglycemia following tolbutamide treatment. Blood sugar remained persistently low in...

MGCD0103, an isotype-selective histone deacetylase inhibitor (HDACi), has been clinically evaluated for the treatment of hematologic malignancies and advanced solid tumors, alone and in combination with standard-of-care agents. In order to investigate the effects of MGCD0103 on the metabolic capacity of cytochrome P450 (CYP) enzymes, a cocktail method was employed to evaluate the activities of ...

A selective and sensitive liquid chromatography-tandem mass spectrometry method was developed and validated for quantitation of bupropion (BUP) and its metabolite hydroxybupropion (HBUP) in rat plasma and urine using carbamazepine as an internal standard. Chromatographic separation was achieved on a SB-C18 column at 30 °C, using the gradient elution of 0.1 % formic acid in water and acetonitril...
