General description

A calcium metabolism regulator. A potent and specific inhibitor of bone resorption at doses devoid of any significant detrimental effect on bone growth and mineralization. Effective in a variety of conditions characterized by pathologically enhanced bone turnover, including Paget′s disease, hypercalcemia of malignancy, osteolytic bone metastasis, and steroid-induced cell death in vitro. Provided in a hydrated form containing five molecules of water.
A potent and specific inhibitor of bone resorption that does not cause any significant detrimental effect on bone growth and mineralization at concentrations used. Effective in a variety of conditions characterized by pathologically enhanced bone turnover, including Paget’s disease, hypercalcaemia of malignancy, osteolytic bone metastasis, steroid-induced osteoporosis, and idiopathic osteoporosis. Inhibits breast cancer cell growth by inducing cell death in vitro. Provided in hydrated form, contains five molecules of water.

T4 RNA ligase catalyzes the synthesis of ATP beta,gamma-bisphosphonate analogues, using the following substrates with the relative velocity rates indicated between brackets: methylenebisphosphonate (pCH(2)p) (100), clodronate (pCCl(2)p) (52), and etidronate (pC(OH)(CH(3))p) (4). The presence of pyrophosphatase about doubled the rate
