Abstract
The binding on hydroxyapatite has been studied of inorganic pyrophosphate (PPj) and two diphosphonates, disodium ethane-1-hydroxy-1,1-diphosphonate (EHDP) and disodium dichloromethylene diphosphonate (Cl2MDP). The binding is greatest for PPi, less for EHDP and least for Cl2MDP. The binding of all three is accompanied by a release of orthophosphate into the solution and an uptake of calcium by the crystals. A competition exists between EHDP and PPi, EHDP being more potent in displacing PPi than the reverse. An analysis with Scatchard plots suggests that the binding is not restricted to one class of binding sites with equal affinity and that the affinity of the first site is in the order EHDP>PPi>Cl2MDP. The results correlate well with previous data on the effect of these compounds on apatite crystal formation and dissolutionin vitro and on bone formation and resorptionin vivo
Résumé
La liaison du pyrophosphate inorganique (PPi) et de deux diphosphonates, l’éthane-1-hydroxy-1,1-diphosphonate disodique (EHDP) et le dichlorométhylène diphosphonate disodique (Cl2MDP), sur l’hydroxyapatite a été étudiée. Le PPi est lié plus fortement que l’EHDP, tandis que le Cl2MDP se lie le moins fortement. La liaison de ces trois substances s’accompagne d’une libération d’orthophosphate dans la solution et d’une adsorption de calcium par les cristaux. Il existe une compétition entre l’EHDP et le PPi; la capacié de l’EHDP à déplacer le PPi est plus grande que celle du PPi à déplacer l’EHDP. L’analyse des résultats à l’aide des fonctions de Scatchard suggère que la liaison n’est pas limitée à une catégorie de sites de liaison ayant une affinité constante et que l’affinité du premier site de liaison est plus grande pour l’EHDP que pour le PPi et plus grande pour le PPi que pour le Cl2MDP. Ces résultats sont en accord avec des résultats précédents concernant l’effet de ces composés sur la formation et la dissolution de cristaux d’apatitein vitro et la formation et la résorption osseusein vivo.
Zusammenfassung
Die Bindung von anorganischem Pyrophosphat (PPi) und zwei Diphosphonaten—Dinatrium-Äthan-1-hydroxy-1,1-diphosphonat (EHDP) und Dinatrium-Dichloromethylen-Diphosphonat (Cl2MDP)—an Hydroxyapatit wurde untersucht. Die Bindung ist am stärksten bei PPi, schwächer bei EHDP und am schwächsten bei Cl2MDP. Bei der Bindung aller drei Substanzen erfolgt gleichzeitig eine Abgabe von Orthophosphat in die Lösung und eine Aufnahme von Calcium durch die Kristalle. Es besteht eine Kompetition zwischen EHDP und PPi, wobei EHDP stärker ist im Verdrängen von PPi als umgekehrt. Eine Analyse mit Scatchard-Kurven weist darauf hin, daß die Bindung nicht auf eine Klasse von Stellen mit konstanter Affinität beschränkt ist und daß die Affinität der ersten Bindungsstelle die Reihenfolge EHDP>PPi>Cl2MDP hat. Die Resultate stimmen gut überein mit früheren Befunden über die Wirkung dieser Verbindungen auf die Bildung und Auflösung von Apatitkristallenin vitro und auf die Knochenbildung und-resorptionin vivo.
