| Abstract: | Abstract Several novel quaternary pyridinium bisphosphonates have been synthesised and their efficacy as potential anti-resorptive bone agents have been tested in Dictyostelium discoideum. This assay has been shown to accurately reflect the potency of a bisphosphonic acid as an anti-resorptive compound. All the quaternary bisphosphonates are very potent growth inhibitors but results indicate that the more potent compounds are those containing hydrophobic, bulky groups. |
