Olpadronic acid
Based on 1 Customer Validation
Olpadronic acid (Olpadronate) is an orally active amino-bisphosphonate and inhibits bone resorption. Olpadronic acid prevents bone destruction and tumor growth in the skeletal prostate cancer mouse model. Olpadronic acid can be used for research of osteoporosis, malignancies and rheumatoid arthritis.

Olpadronic acid (5 × 10-8-10-4 M) potently inhibits bone resorption in foetal mouse bone assays with a CI50 of 5 × 10-7 M[1].
Olpadronic acid inhibits breast cancer cell adhesion to bone matrices[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Olpadronate maintains and restores mechanical bone quality in rats with immobilisation- or ovariectomy-induced osteopaenia[1].
Olpadronate (90 mg/kg/day; p.o.; long-term) improves the biomechanical strength of long bones in normal mice without impairing bone mineralisation[1].
Olpadronate enhances the anabolic bone effects of simultaneous hPTH administration in normal rats by inhibiting remodelling of newly formed bone[1].
Olpadronic acid (4-16 ug/100g; i.p.; once weekly; 30 days) prevents Cyclosporine-induced high bone resorption and trabecular bone loss in male Sprague-Dawley rats[2].
Olpadronate (2.6 mmol/L; i.v.; 3 doses total) prevents bone destruction and tumor growth in the skeletal prostate cancer mouse model[3].

-
Animal Model:Mice[1]
-
Dosage:90 mg/kg/day
-
Administration:p.o.; long-term
-
Result:Improved the resistance of long bones to deformation and fracture.
Increased external diameter and diaphyseal moments of inertia for flexion and torsion.
Did not impair matrix calcification.
-
Animal Model:Sprague-Dawley rats (male, ~5 months old, 250-300 g, cyclosporine-induced osteopenia)[2]
-
Dosage:4; 8; 16 ug/100g rat
-
Administration:i.p.; once weekly; 30 days
-
Result:Caused a transient, statistically significant increase in serum bone-alkaline phosphatase (b-ALP) on day 14 in groups receiving 8 ug/100g and 16 ug/100g, and a significant reduction in serum b-ALP on day 30 compared to control and cyclosporine-only groups.
Significantly reduced urinary deoxypyridinoline (DPyr) excretion on days 14 and 30 compared to cyclosporine-only rats, with the 16 ug/100g dose causing a greater reduction than the lower doses.
Significantly increased BMD in the total skeleton, whole femur, lumbar spine, and proximal tibia on day 30 compared to control and cyclosporine-only rats.
Resulted in significantly higher proximal tibia, whole femur, and lumbar spine BMD with the 16 ug/100g dose compared to the lower olpadronic acid doses.
Showed no significant effects on middle tibia BMD with any dose.
-
Animal Model:NCR nude (nu/nu) mice (6-month-old male, immunocompromised, intratibial inoculation with PC-3-GFP human prostate cancer cells)[3]
-
Dosage:2.6 mmol/L
-
Administration:i.v.; 3 times total (1 month pre-implantation, at implantation, and 30 days post-implantation)
-
Result:Prevented tumor volume from exceeding 1 cm3.
Reduced GFP tumor area by 66% compared to tumor-bearing control mice.
Reduced mean X-ray score to 0.9, with 8 of 19 mice showing no tibial abnormalities and 11 showing only minor abnormalities, representing a dramatic reduction in bone lesion severity that was significantly greater than that seen with pamidronate.
Reduced serum calcium to 10.7 mg/dL compared to tumor-bearing control mice.
Reduced serum parathyroid hormone-related protein (PTHrP) to 110 pg/mL compared to tumor-bearing control mice.
Reduced serum osteoprotegerin to 58 pg/mL compared to tumor-bearing control mice.
