52 results about "Cyclic guanosine monophosphate" patented technology

Cyclic guanosine monophosphate (cGMP) is a cyclic nucleotide derived from guanosine triphosphate (GTP). cGMP acts as a second messenger much like cyclic AMP. Its most likely mechanism of action is activation of intracellular protein kinases in response to the binding of membrane-impermeable peptide hormones to the external cell surface.

Soluble guanylate cyclase activators

The invention relates to compounds having the structure of Formula (I) and pharmaceutically acceptable salts thereof, which are soluble guanylate cyclase activators. The compounds are capable of modulating the body's production of cyclic guanosine monophosphate (“cGMP”) and are generally suitable for the therapy and prophylaxis of diseases which are associated with a disturbed cGMP balance. The compounds are useful for treatment or prevention of cardiovascular diseases, endothelial dysfunction, diastolic dysfunction, atherosclerosis, hypertension, pulmonary hypertension, angina pectoris, thromboses, restenosis, myocardial infarction, strokes, cardiac insufficiency, pulmonary hypertonia, erectile dysfunction, asthma bronchiale, chronic kidney insufficiency, diabetes, or cirrhosis of the liver.

Preparation method of tadalafil and intermediate of tadalafil

The invention relates to a preparation method of a selective and reversible inhibitor tadalafil of cyclic guanosine monophosphate (cGMP) specific phosphodiesterase 5 (PDE5). The method comprises the following steps: carrying out an esterification reaction on D-tryptophan as an initial raw material and methanol under catalysis of sulfuric acid to generate D-tryptophan methyl ester (an intermediate1); carrying out a Pictet-Spengler (P-S) reaction on the D-tryptophan methyl ester and heliotropin to prepare (1R,3R)-1-(1,3-benzodioxol-5-yl)-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole-3-carboxylic acid methyl ester hydrochloride (an intermediate 2); carrying out an amidation reaction on the (1R,3R)-1-(1,3-benzodioxol-5-yl)-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole-3-carboxylic acid methyl ester hydrochloride and chloroacetyl chloride to prepare (1R,3R)-1-(1,3-benzodioxol-5-yl)-2-(2-chloroacetyl)-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole-3-carboxylic acid methyl ester (an intermediate 3); andfinally carrying out a cyclization reaction on the (1R,3R)-1-(1,3-benzodioxol-5-yl)-2-(2-chloroacetyl)-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole-3-carboxylic acid methyl ester and a methylamine alcohol solution to obtain the tadalafil. The method provided by the invention has the advantages of easily available raw materials, simple operation, greenness, environmental protection and low costs, andis suitable for industrial production.

Red date-flavored short biscuit and preparation method thereof

The present invention relates to the technical field of leisure foods, and specifically discloses a red date-flavored short biscuit and a preparation method thereof. The red date-flavored short biscuit disclosed by the invention is prepared from the following raw materials in parts by weight: 18 to 22 parts of skim milk powder, 28 to 32 parts of red date powder, 20 to 30 parts of wheat flour, 32 to 36 parts of white sugar powder, 24 to 26 parts of edible vegetable oil, 0.3 to 0.5 part of lecithin, 0.1 to 0.3 part of sodium bicarbonate, 0.015 to 0.025 part of edible salt and 0.75 to 0.85 part of water. With scientific and reasonable material selection and production, the red date-flavored short biscuit provided by the invention has the advantages: the biscuit provided has a strong natural flavor, the monotonicity of traditional biscuits and the homogenization characteristics of biscuit products on the market are broken, and the new application of the biscuit is expanded; when matching with yoghurt or milk with other flavors, the biscuit can improve the taste, improve the added value of the product and attract the eyeball of consumers; and the red date powder contains a plurality ofbioactive substances such as jujube polysaccharides, flavonoids, saponins, triterpenes, alkaloids, cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP), and has a pluralityof health-care and treating effects on human body.

Finasteride and sildenafil compositions and applications

The human body is mediated by a large number of chemicals and chemical processes where imbalances can result in an abnormal condition that affects part or all of the human body. Amongst these conditions are hair loss and male impotence or erectile dysfunction, both of which can have psychological consequences for the patient and others as they can be tied to relationship difficulties and self-image. 5α-reductase Type II inhibitors prevent DHT production and reduce androgen activity in key tissues such as prostate and scalp. Similarly, an inhibitor of cyclic guanosine monophosphate (cGMP) specific phosphodiesterase type 5 (PDE5) can lead to improved vasodilation and blood flow. It would be beneficial to provide patients with either of these treatments within a topical cream form allowing localized targeted delivery.

Method for extracting cyclic adenosine monophosphate and cyclic guanosine monophosphate from jujube fruits

The invention discloses a method for extracting cyclic adenosine monophosphate and cyclic guanosine monophosphate from jujube fruits. The method comprises the steps of preparation of crude jujube extracts, alcohol precipitation, macroporous resin chromatographic column separation, membrane separation and preparative liquid chromatography separation. In the method, alcohol is used as an extractingsolution, the three separation ways including macroporous resin chromatographic column separation, membrane separation and preparative liquid chromatography separation are adopted, the cyclic adenosine monophosphate and the cyclic guanosine monophosphate which are obtained by using the method are high in purity, and the purity of the cyclic adenosine monophosphate and the purity of the cyclic guanosine monophosphate reach 90% or above respectively. When the preparative liquid chromatography is applied, on-line monitoring can be achieved, target separation is achieved, and the separation efficiency is high.
