Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 17557-76-5, Name is 4,4′-Diamino-[1,1′-biphenyl]-2,2′-dicarboxylic acid, SMILES is O=C(C1=CC(N)=CC=C1C2=CC=C(N)C=C2C(O)=O)O, belongs to isoquinoline compound. In a document, author is Elbermawi, Ahmed, introduce the new discover, Name: 4,4′-Diamino-[1,1′-biphenyl]-2,2′-dicarboxylic acid.
Bioactive isoquinoline alkaloids from Glaucium arabicum
Phytochemical investigation of the aerial parts of Glaucium arabicum Fresen. (Papaveraceae) led to the isolation of two previously undescribed isoquinoline alkaloids araglaucine A, and araglaucine B, together with seven known ones 1-[(3′,4′-dimethoxy-2′-methylcarboxy)benzoyl]-6,7-methylenedioxy isoquinoline (araglaucine C), (7R,14S)-trans-N-methylcanadinium nitrate, (R,S)-trans-N-methylstylopine, 14-hydroxy-N-methyl canadine, 14-hydroxy-N-methyl stylopine, protopine, norsanguinarine, as well as beta-sitosterol, and beta-sitosterol 3-O-beta-D glucoside. Their structural elucidation was based on the measurements of 1D, 2D NMR, HRESIMS, UV, IR and X-ray crystallography. The compounds were evaluated for their anti-melanogenesis activity using B16 melanoma cell lines. Compound (7R,14S)-trans-N-methylcanadinium nitrate exhibited a promising melanin synthesis inhibitory activity (similar to 35%) at concentration 5 mu g/ml (12.01 mu M) with low cytotoxicity (similar to 12%).
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 17557-76-5 is helpful to your research. Name: 4,4′-Diamino-[1,1′-biphenyl]-2,2′-dicarboxylic acid.
