Descriptions:
Cryptotanshinone9(CT), the major tanshinone isolated from Salvia miltiorrhiza Bunge, can suppress Bcl-2 expression and augment Fas sensitivity in DU145 cells, and JNK and p38 MAPK act upstream of Bcl-2 expression in Fas-treated DU145 cells; CT significantly blocks activation of these kinases and sensitizes several tumor cells to a broad range of anti-cancer agents; suggests that CT has therapeutic potential in the treatment of human prostate cancer.[1]
Cryptotanshinone has an inhibitory effect on MMP-9 production and migration of human aortic smooth muscle cells treated with TNF-alpha in a dose-dependent manner, suggests that CT has anti-atherosclerosis and anti-neointimal formation activity.[2]
Cryptotanshinone enhances TNF-α-induced apoptosis in chronic myeloid leukemia KBM-5 cells, in comparison with the treatment with either drug alone, the treatment with cryptotanshinone further suppressed TNF-α-mediated expression of c-FLIP.[3]
Cryptotanshinone as an AR inhibitor to suppress androgen/AR-mediated cell growth and PSA expression by blocking AR dimerization and the AR-coregulator complex formation; and CT effectively inhibits CWR22Rv1 cell growth and expressions of AR target genes in the xenograft animal model; the previously un-described mechanisms of CT may explain how CT inhibits the growth of prostate cancer (PCa)cells and help us to establish new therapeutic concepts for the treatment of PCa.[4]
Cryptotanshinone induces ER stress-mediated apoptosis in HepG2 and MCF7 cells , also evidences sensitizing effects to a broad range of anti-cancer agents including Fas/Apo-1, TNF-α, cisplatin, etoposide or 5-FU through inducing ER stress, highlighting the therapeutic potential in the treatment of human hepatoma and breast cancer.[5]
Cryptotanshinone protects primary cortical neurons from -induced neurotoxicity through the activation of /pathway, such neuroprotective effects may be of interest in AD and other .[6]
Cryptotanshinone can inhibits cyclooxygenase-2 enzyme activity.[7]
