Biological Activity

Description	Pamidronate Disodium (CGP 23339AE) is a nitrogen containing bisphosphonate, used to prevent osteoporosis.Pamidronate Disodium is a inhibitor of bone resorption factor.

In vitro
In vitro	Pamidronate increases OPG mRNA levels and protein secretion by hOB by up to 2- to 3-fold in a dose-dependent fashion with a maximum effect at 1 µM after 72 hours. Artemisinin prevents the inhibitory effects of the glucocorticoid dexamethasone on OPG mRNA and protein production. Pamidronate induces type I collagen secretion and alkaline phosphatase activity by 2-fold. ^[1] Pamidronate has a more pronounced calcium-lowering action than etidronate (etidronic acid) and clodronate (clodronic acid) and provides a longer period of normocalcaemic remission. ^[2] Pamidronate (APD) dose-dependently inhibits resorption of calcium phosphate films by equine OCLs with an IC(50) of 0.58 μM in one horse. Pamidronate also dose-dependently inhibits the number of OCLs present in BM cultures after 7 days. ^[3]

In Vivo
In vivo	Pamidronate administration significantly suppresses this increase below the control level in the tibia and distal femur of oophorectomized rats. Pamidronate significantly increases bone density and ash weight in both sham-operated and oophorectomized rats. ^[4] Pamidronate inhibits all significant effects of growth hormone (GH) and it also decreases the IGF-I levels in rats treated with growth hormone (GH). Pamidronate itself results in increased the bone density and ash weight of the tibia and decreased urinary DPD excretion. ^[5]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
