説明 | Osthole (Osthol), a potential inhibitor of histamine H1 receptor, has been shown to stimulate osteoblast proliferation and differentiation. |
In vitro | The LD50 values of Osthole in various animals have been determined as follows: in rats, it exceeds 125 mg/kg when administered intravenously (i.v.); in rabbits, it is over 35 mg/kg (i.v.); and in dogs, it surpasses 150 mg/kg (i.v.). |
In vivo | Osthol, when introduced to pre-washed rabbit platelets, inhibits platelet aggregation and ATP release induced by ADP, arachidonic acid, platelet-activating factor (PAF), collagen, ionophore A23187, and thrombin. In human osteoblasts, osthol promotes cell differentiation through the bone morphogenetic protein-2 / p38 and extracellular signal-regulated kinase 1/2 pathways. Additionally, in cell cultures, osthol suppresses the secretion of the hepatitis B virus by enhancing the glycosylation of HBsAg. |
細胞研究 | Osthole is dissolved in 96% ethyl alcohol and then sterilized through a 0.22 μg/mL filter and stored at 4°C as stock solutions for later dilution[1]. Peripheral blood samples are collected from participants between 7.00 and 9.00 a.m. on the first study day and these are concentrated in grouping tubes with K3EDTA. Fresh PBMCs are then prepared. Isolated cells are seeded on 24-well plates at 1×106 per well with RPMI-1640 and supplemented with 1% heat inactivated human AB serum, 1% gentamicin and 0.25% PHA. Active reagents are added to each well after 24 h and pure medium formed the control for each substance. Cells are then harvested after a further three days[1]. |
