Biological activity of a phloroglucinol glucoside derivative from Conyza aegyptiaca.
The phloroglucinol glucoside derivative [2,4-dihydroxy-6-(beta-D-glucopyranosyloxy)phenyl]-butan-1-one (1), roseoside (2), and kaempferol-3-O-beta-D-glucopyranoside (3) were isolated from the aerial parts of Conyza aegyptiaca (L.). To the best of our knowledge, this is the first isolation of compounds 1-3 from C. aegyptiaca. Their structures were determined by spectroscopic techniques including...

متن کاملUp-regulation of tumor suppressor genes by exogenous dhC16-Cer contributes to its anti-cancer activity in primary effusion lymphoma
Primary effusion lymphoma (PEL) is a rare and highly aggressive B-cell malignancy with Kaposi's sarcoma-associated herpesvirus (KSHV) infection, while lack of effective therapies. Our recent data indicated that targeting the sphingolipid metabolism by either sphingosine kinase inhibitor or exogenous ceramide species induces PEL cell apoptosis and suppresses tumor progression in vivo. However, t...
متن کاملSCHEMA recombination of a fungal cellulase uncovers a single mutation that contributes markedly to stability.
A quantitative linear model accurately (R(2) = 0.88) describes the thermostabilities of 54 characterized members of a family of fungal cellobiohydrolase class II (CBH II) cellulase chimeras made by SCHEMA recombination of three fungal enzymes, demonstrating that the contributions of SCHEMA sequence blocks to stability are predominantly additive. Thirty-one of 31 predicted thermostable CBH II ch...
