New diphosphonate compounds for skeletal imaging: comparison with methylene diphosphonate.
Radiology, 1983Three-hour biodistribution of Tc-99m complexes of six diphosphonates was compared in rabbits with tibial lesions to determine which was best for detection of focal bone lesions. Sr-85 was used as a standard. N,N-dimethylaminomethylene diphosphonate (DMAD) was the only agent with a higher lesion/normal bone ratio than methylene diphosphonate (MDP ...

Synthesis of Glycerol-1,3-diphosphonic Acid
Canadian Journal of Biochemistry, 1973The synthesis of glycerol-1,3-diphosphonic acid, the phosphonic acid analogue of the naturally occurring glycerol-1,3-diphosphoric acid, is described. The phosphonic acid analogue was obtained in an overall yield of 29.7%, by heating a mixture of 1,3-dibromo-2-hexadecanoyloxypropane and triethyl phosphite to 140° for 48 h, distilling off in vacuo the ...

Some aliphatic diphosphonic tetrachlorides. Part II. Some reactions of diphosphonic tetrachlorides
Journal of the Chemical Society C: Organic, 1967Aliphatic 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 ...

Benign myocardial uptake of hydroxymethylene diphosphonate
Nuclear Medicine Communications, 1994During 'routine' bone scanning with diphosphonates, 10 elderly men were noted to show prominent myocardial uptake of Tc-hydroxymethylene diphosphonate (HDP) consistently, but no heart activity was seen with Tc-methylene disphosphonate (MDP). None had evidence of recent myocardial injury and the uptake persisted over a period of many months.

Diphosphonate und Harnsteinbildung
1974Die Harnsteine bestehen zum grosten Teil aus kristallinem Material, wie Calciumoxalat, Calciumphosphat, Magnesiumammoniumphosphat, Urat oder Harnsaure, worunter die Calciumsalze den wichtigsten Platz einnehmen. Somit ist in der Pathophysiologie der Harnsteinbildung die Ausfallung dieser Substanzen von wesentlicher Bedeutung.
