Ppi and bisphosphonates
WebNov 20, 2000 · Like PPi, bisphosphonates form a three-dimensional structure capable of binding divalent metal ions such as Ca 2+, Mg 2+, and Fe 2+ in a bidentate manner, by coordination of one oxygen from each phosphonate group with the divalent cation. The affinity for calcium can be increased further if one of the side chains (R 1) is a hydroxyl ( … WebAs detailed in Figure 1, B, and distinct from PPi, nearly all bisphosphonates in current clinical use also have a hydroxyl group attached to the central carbon (termed the R 1 position). The flanking phosphate groups provide bisphosphonates with a strong affinity for hydroxyapatite crystals in bone (and are also seen in PPi), whereas the hydroxyl motif further increases a …
