Working concentration: mg/ml;

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.

Mechanism of Action

Targets/IC50/Ki
protein tyrosine phosphatase [6]
In vitro
Etidronate inhibits directly osteoclastic bone-resorbing activity by pit assay. This compound also directly induces apoptosis and disrupts actin rings in osteoclasts. [1]
In vivo
Etidronate, when administered s.c. repeatedly at 10 or 40 mg/kg/day, gradually suppresses the adjuvant-induced allodynia In the rats with adjuvant arthritis, as assessed by 10-g von Frey hair. This compound (10-40 mg/kg/day) suppresses the adjuvant-induced mechanical allodynia in rat hindpaw. It (5–10 mg/kg/day) dose-dependently prevents the decrease in bone mineral density (BMD) in the proximal tibia of the arthritic rats. [2] This chemical inhibits the histidine decarboxylase induction, but not the other inflammatory reactions induced by alendronate. It (unlike clodronate) also inhibits alendronate-induced BP-line formation in mice (even at 40 mmol/kg). This compound (160 mmol/kg) also inhibits the physicochemical changes in the tibia induced by six, weekly injections of alendronate. [3] It (10 mg/kg) combined with Calcitriol after subtotal nephrectomy (SNx) significantly inhibits thoracic and abdominal aortic calcification 3 weeks after the operation in rats. [4] This chemical (5 mg/kg or 10 mg/kg) significantly reduces the thoracic and abdominal aortic calcification induced by calcitriol in the renal failure rat. It (5 mg/kg or 10 mg/kg) also reduces the dysfunction in aortic contraction. This compound (5 mg/kg) reverses the reduction in the aortic expression of matrix Gla protein mRNA observed in nephrectomized rats. [5]
