As part of our ongoing silybin project, this study aims to introduce a basic nitrogen-containing group to 7-OH of 3,5,20-O-trimethyl-2,3-dehydrosilybin or 3-OH of 5,7,20-O-trimethyl-2,3-dehydrosilybin via an appropriate linker for in vitro evaluation as potential anti-prostate cancer
BACKGROUND
We have shown that compared with silybin, 2,3-dehydrosilybin (DHS) exhibits more potent in vitro anticancer activities alone or in combination with tumor necrosis factor (TNF)-alpha. Since TNF-alpha sensitization is related to DNA topoisomerase (topo) inhibition, DHS may be a potent topo
Silybin or silibinin, a flavonolignan isolated from Milk thistle seeds, is one of the popular dietary supplements and has been extensively studied for its antioxidant, hepatoprotective and anti-cancer properties. We have envisioned that potency of silybin could be further enhanced through suitable
Silybin, the major flavonoid of Silybum marianum, is widely used to treat liver diseases such as hepatocellular carcinoma and cirrhosis-associated insulin resistance. Research so far has focused on its anti-oxidant properties. Here, we demonstrate that silybin and its derivative dehydrosilybin
Silybin or silymarin extract has been used to treat liver diseases, and has now been entered into clinical trials for cancer treatment. Here, we compared antioxidant and anticancer activities between silybin and its oxidized form 2,3-dehydrosilybin (DHS). With IC50 at three-fold lower concentrations
Silymarin, a standardised extract of Silybum marianum (milk thistle), comprises mainly of silybin, with dehydrosilybin (DHSB), quercetin, taxifolin, silychristin and a number of other compounds which are known to possess a range of salutary effects. Indeed, there is evidence for their role in
BACKGROUND
UV radiation from sunlight is a very potent environmental risk factor in the pathogenesis of skin cancer. Exposure to UV light, especially the UVA part, provokes the generation of reactive oxygen species (ROS), which induce oxidative stress in exposed cells. Topical application of
Silymarin is the standardized extract from the fruits of Silybum marianum (L.) Gaertn., a well-known hepatoprotectant and antioxidant. Recently, bioactive compounds of silymarin, i.e., silybins and their 2,3-dehydro derivatives, have been shown to exert anticancer activities, yet with unclear
Silybin is considered to be the main biologically active component of silymarin. Its oxidized derivative 2,3-dehydrosilybin typically occurs in silymarin in small, but non-negligible amounts (up to 3%). Here, we investigated in detail complex biological activities of silybin and 2,3-dehydrosilybin
