The invention belongs to the field of traditional Chinese medicine manufacturing, and relates to application of leonurine to preparation of a medicament for treating 2-type diabetes. Animal experiments prove that the fasting blood glucose of a 2-type diabetes mouse, i.e., a db/db mouse, can be lowered by the leonurine, and the tolerance of oral glucose is improved; and meanwhile, fasting plasma insulin is increased, the plasma triglyceride is reduced and the content of the plasma high-density lipoprotein is increased. Experiment results also show that the expression of liver glucose metabolic enzymes such as glucokinase, glucose-6-phosphatase and phosphoenolpyruvate carboxyl enzyme is adjusted by the leonurine in an Akt dependent mode; and the biological response of an inflammatory mediator, such as generation of TNF (Tumor Necrosis Factor)-alpha, degradation of IkB-alpha and subsequent phosphorylation of NF-kBp65, is suppressed. Through the leonurine, the inflammatory state of the 2-type diabetes can be corrected, and the symptoms of the 2-type diabetes can be improved; and the leonurine can be used as a treatment medicament to be applied to the treatment of the 2-type diabetes.

The invention relates to the field of gene engineering, and discloses a construction and an expression for two engineering bacteria of two human glucagon-like peptide-1 analogues, and a preparation method for the objective peptides. The objective peptides are formed by inserting objective sequence after double digestions, adding His labels at the front ends of fusion proteins, obtaining objective peptides by cutting the fusion proteins with acid via gaining the fusion proteins, and after an isoelectric precipitation, obtaining the objective peptides again through an affinity chromatography of a Ni agarose gel after an isoelectric precipitation. Freeze-dried objective peptides are dissolved in a PBS buffer solution, oral glucose tolerance test and determination of serum insulin concentration are carried out on normal ICR mice. The two analogues are modified peptides of human glucagon-like peptide-1. Experiments demonstrate that both the two peptides have effects for reducing blood glucose and can be used for treating type 2 diabetes mellitus. Furthermore, the invention also provides the preparation method for the peptides.

The present invention is directed to pyridin-2-one derivatives, pharmaceutical compositions containing them and their use as antagonists of the EP3 receptor, for the treatment of for example, impaired oral glucose tolerance, elevated fasting glucose, Type II Diabetes Mellitus, Syndrome X (also known as Metabolic Syndrome) and related disorders and complications thereof.

Inorganic anions nitrate and nitrite influence metabolic rate and glucose homeostasis. Infusion of nitrite iv caused an acute drop in resting energy expenditure (oxygen consumption) and nitrate, when given perorally, caused a reduction in oxygen consumption during exercise and a depression of the increase in blood glucose observed after an oral glucose tolerance test. The doses of nitrate and nitrite did not cause any detectable change in methemoglobin levels of blood. Also, nitrate and nitrite did not alter lactate levels in blood. This discovery provides useful treatments to regulate the energy expenditure and glucose homeostasis of a mammal by administration of inorganic nitrite and/or nitrate.
