Cryptotanshinone and tanshinone IIA are two significant tanshinones in this plant.
(-)-MK 801 Maleate Cryptotanshinone was also observed to possess diverse biological activities, such as anti inflammatory, anti oxidative, anti mutagenic, anti platelet aggregation, anti cyclooxygenase II activities and displayed the most powerful antibacterial activity among tanshinones. Furthermore, Suh et al. pointed out that cryptotanshinone had anti atherosclerosis and anti neointimal formation activity through inhibition of smooth muscle cell migration. However, there is no related report about the effect of cryptotanshinone on inflammatory cell infiltration. The importance of C5a in several inflammatory diseases is demonstrated by the fact that agents that block the action of C5a also suppress inflammatory pathologies in several animal models.
Primary human macrophages A 205804 were prepared from healthy volunteers. In brief, peripheral blood mononuclear cells were isolated from heparinized blood by centrifugation over Ficoll?Hypaque gradients. PBMC at the interface were aspirated, diluted to 50 ml volume with phosphatebuffered saline, washed three times and centrifuged at 400 g for 10 min. After the final wash, PBMC were suspended in RPMI 1640 containing 10% FCS, streptomycin and penicillin. The total number of viable PBMC in the suspension was determined by trypan blue dye exclusion. Then PBMC were plated onto 35 mm culture dishes and incubated overnight at 371C, 5% CO2, in a humidified atmosphere to allow monocytes to adhere to the plate.
miltiorrhiza were extracted with ethanol at room temperature.
