Fermentation, Isolation, Structural Elucidation and Biological Activities

A fermentation broth of an unidentified fungus (N983-46) was found to produce DNAgyrase inhibitors, CJ-12,371 (1) and CJ-12,372 (2). Following isolation by solvent extraction and silica gel and ODS(reverse phase) chromatographies, the structures were determined to be novel spiro-ketal compounds with S-connguration at position C-l. CJ-12,371 and CJ-12,372 inhibit both DNA supercoiling and relaxa...

ISOLATION AND STRUCTURAL ELUCIDATION OF THE FIRST KNOWN C-HOMOPROTOBERBERINE

A novel C-homoprotoberberine alkaloid, Hediamine (2), has been isolated from the roots of Berberis actinucantha (Berberidaceae). Conclusive proof for the structure of hediamine was obtained by its comparison with the isomeric lactam (4), by chemical transformation, and by means of spectroscopic techniques (UV, IR, MS, NMR).

Isolation and Structural Elucidation of Antiproliferative Compounds of Lipidic Fractions from White Shrimp Muscle (Litopenaeus vannamei)

Shrimp is one of the most popular seafood items worldwide, and has been reported as a source of chemopreventive compounds. In this study, shrimp lipids were separated by solvent partition and further fractionated by semi-preparative RP-HPLC and finally by open column chromatography in order to obtain isolated antiproliferative compounds. Antiproliferative activity was assessed by inhibition of ...

Isolation of antimicrobial compounds from guava (Psidium guajava L.) and their structural elucidation.

Four antibacterial compounds were isolated from leaves of guava (Psidium guajava L.), and the structures of these compounds were established on the basis of chemical and spectroscopic evidence. Two new flavonoid glycosides, morin-3-O-alpha-L-lyxopyranoside and morin-3-O-alpha-L-arabopyranoside, and two known flavonoids, guaijavarin and quercetin, were identified. The minimum inhibition concentr...

Isolation and Structure Elucidation of Phenolic Compounds of Carob Leaves Grown in Egypt

Carob leaves (Ceratonia siliqua L.), grown in Egypt have not fully identified in Egypt. Therefore, eight major phenolic compounds were isolated from the aqueous ethanolic extract using different methods of chromatography; gallic acid, quercetin 3-O-4C1-B-D-glucoside (Isoquercetin), Kaempferol 3-O1C4-"-Lrhamnoside (Afzelin), Quercetin 3-O-1C4-"-L-rhamnoside (Quercitrin), 1,2,6 tri-O-galloyl-B-D4...
