Biological activity of Sinularia notanda
… variety of cembrane diterpenoids with a range of biological activities are reportedly isolated from marine soft coral, and most notably these compounds possess anticancer properties. The investigation of a marine soft coral, Sinularia notanda, for novel bioactive compounds is presented here. The …

Biological activity of palmitoylcarnitine in prostate cancer
… progression, revealed a significant overlap in activity between palcar and DHT, suggesting that palcar may have a potential role in promoting cancer progression. In PC3 cells through the use of real time RT-PCR palcar was shown to induce glycolysis. In conclusion, it is suggested that palcar may …

Cellular uptake and biological activity of synthetic hammerhead ribozymes
… will require chemical modifications that improve biological stability and a fundamental understanding of cellular uptake mechanisms. Chimeric 2'-O-methylated hammerhead ribozymes proved to be significantly more stable (>4000-fold) in serum than unmodified RNA ribozymes and exhibited high in vitro …
