Experimental study of inhibitor of tumor necrosis factor-α combined with ulinastatia on the treatment of severe acute pancreatitis in rats

Study on extraction of α-amylase inhibitor from white-bean and its enzyme characteristics;

Purification、characteristics and distribution of α-amylase inhibitor;

Purification and partial characterization of a glycoprotein α-amylase inhibitor from white kidney beans;

To screen α-glucosidase inhibitor, three methods using the inhibitor activity of amylase, sucrase, maltase as models were established.

The α-glucosidase inhibitor screening experiments showed that,the culture broth of Actinoplanes ueatansis var E-3519 exhibited amylase and sucrase inhibitory activities.

A simple and effective method was established to separate 3 major components of validamycin by ion exchange chromatography, these components were all important chemical intermediates for the preparation of N-substituted aminocyclitol which can be used to synthesize α-glucosidase inhibitor-a new type of antidiabet drug.

Research advance of preparation method of alpha-amylase inhibitor;

The preparation process of alpha-amylase inhibitor from natural plant and microorganism which has hypoglycemic activity was detailedly discussed in this paper.

Extraction of alpha-Amylase Inhibitor by Aqueous Two-phase Extraction was studied.
