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.

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.
