Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Zhang, Yu-Bo, once mentioned the application of 767-69-1, Name is 6-Bromo-7H-purine, molecular formula is C5H3BrN4, molecular weight is 199.01, MDL number is MFCD00022648, category is piperidines. Now introduce a scientific discovery about this category, Recommanded Product: 767-69-1.
Matrine-Type Alkaloids from the Roots of Sophora flavescens and Their Antiviral Activities against the Hepatitis B Virus
Eight new matrine-type alkaloids, flavesines G J (1-4), alopecurine B (5), 7,11-dehydro-oxymatrine (6), 10-oxy-5,6-dehydromatrine (7), and 10-oxysophoridine (8), along with nine known analogues (9-17) were isolated from the roots of Sophora flavescens. Compounds 1-3 are the first natural matrine-type alkaloids with an openloop ring D, while compound 4 represents an unprecedented dimerization pattern constructed from matrine and piperidine, and 5 is the first example of a matrine-type alkaloid with cleavage of the C5 C-6 bond. The new structures were elucidated by means of spectroscopic data analysis (including NMR, MS, IR, and UV), and the absolute configurations were determined using singlecrystal X-ray diffraction and ECD data. The isolated alkaloids were evaluated for their antiviral activity against hepatitis B virus, and compounds 1, 4, 5, 10, and 14 exhibited comparable antiviral potencies to matrine.
