Diphosphonates in the evaluation of metabolic bone disease

Clinical Rheumatology, 1982
The bone scan may be of value in the assessment of patients with metabolic bone disease. However the superiority of the bone scan when compared to radiology in conditions such as renal osteodystrophy, osteomalacia, primary hyperparathyroidism, and osteoporosis requires substantiation with the newer radiopharmaceuticals which have a higher affinity for ...

Structure of tetrathallium methylene diphosphonate

Materials Chemistry and Physics, 1985
Tl4CH206P2 was found to be monoclinic C2/c, a = 12.647 (6), b = 8.314 (5), c = 9.782 (4), β = 103.0 (9)°, Z = 4. The structure was solved with MULTAN and refined to R(Fo) = 0.075 for 1636 reflections measured with MoKα radiation. The crystal structure can be regarded as being built up of isolated MDP linked together by Tl+ ions.

Diphosphonates: History and mechanisms of action

Metabolic Bone Disease and Related Research, 1981
The history of diphosphonates began with studies of inorganic pyrophosphate. This compound was found to occur in many biological fluids and inhibited the precipitation of calcium phosphates. It also slowed the transformation of amorphous calcium phosphate to its crystalline form, and inhibited crystal aggregation and dissolution.

The Effect of a Diphosphonate on Uremic Hyperparathyroidism

Nephron, 1973
Chronic renal failure in the rat was shown to be associated with parathyroid enlargement, a decreased ash content of the femoral shaft and elevated trabecular bone resorption.

Some aliphatic diphosphonic tetrachlorides. Part II. Some reactions of diphosphonic tetrachlorides

Journal of the Chemical Society C: Organic, 1967
Aliphatic diphosphonic tetrachlorides and Grignard reagents containing aryl groups readily gave diphosphine dioxides, of which several are described. In a similar reaction of the tetrachlorides with Grignard reagents containing branched alkyl groups the products were not the expected diphosphine dioxides, but the products of mono-substitution at each ...

A radiopharmaceutical and clinical comparison of 99mTc-Sn-hydroxymethylene diphosphonate with 99mTc-Sn-hydroxyethylidene diphosphonate.

Radiology, 1980
A comparison of 99mTc labeled hydroxyethylidene diphosphonate (99mTc-HEDP) and hydroxymethylene diphosphonate (99mTc-HMDP), two bone scanning agents differing by a single methyl group, was performed in 20 patients. In nine patients, no difference in scan quality was found.
