Paragraph 0060; 0078; 0081-0082, (2020/02/14)
The invention relates to preparation and application of a sulfonic acid-phosphonic acid ligand. The structure of the sulfonic acid-phosphonic acid ligand comprises sulfonic acid, quaternary ammonium and phosphonic acid groups, and specifically comprises a sulfonic acid betaine-phosphonic acid ligand, a sulfonic acid-zoledronic acid ligand and a sulfonic acid-risedronic acid ligand. The molecular formula of the sulfobetaine-phosphonic acid ligand is C8H21NO10P2S, and the molecular weight of the sulfobetaine-phosphonic acid ligand is 384.2. The molecular formula of the sulfonic acid-zoledronic acid ligand is C8H16O10N2P2S, and the molecular weight of the sulfonic acid-zoledronic acid ligand is 394.23. The molecular formula of the sulfonic acid-risedronate ligand is C10H17O10NP2S, and the molecular weight of the sulfonic acid-risedronate ligand is 405.25. The sulfonic acid-phosphonic acid ligand disclosed by the invention has excellent hydrophilicity and can be coordinated with various metal elements. The molecules have important applications in the following two aspects: 1, the sulfonic acid-phosphonic acid ligand is used for modifying a hydrophobic nano material, so that the hydrophilicity of the material is remarkably improved, and the sulfonic acid-phosphonic acid ligand can be dispersed in a water phase; and 2, a certain inhibition effect is achieved on tumors.

Pharmaceutical compositions, processes for preparing the compositions and methods of using the composition are provided. The pharmaceutical composition comprises an inert core surrounded by an active coating containing one or more bisphosphonic acids or salts thereof, a seal coating surrounding the active coating and an enteric coating surrounding the seal coating. Alendronic acid and alendronate sodium trihydrate are the preferred active ingredients. The composition may be provided in the form of pellets in a capsule or Peltabs. The invention further provides methods for the treatment of disorders caused by the abnormal dissolution or deposition of calcium salts using the inventive compositions.
