Biochem/physiol Actions

Analog of pyrophosphate ion that inhibits the osteoclastic activity leading to bone resorption and osteoporosis. The compound is used in cancer research, especially in skeletal metastases and breast carcinoma. When entrapped in liposomes, it is used for macrophage-selective depletion (macrophage "suicide" technique), especially in spleen and liver. Found also to inhibit collagenase and matrix metalloproteinase1.

Interstitial collagenase present in human jaw cyst extract and purified human fibroblast-type collagenase (MMP-1) were both efficiently inhibited in vitro by clodronate, an osteoactive, antiresorptive bisphosphonate. The IC50 of clodronate to inhibit MMP-1 is 150 microM. These findings suggest an

Anti-CD20 Ab therapy has proven successful for treating B cell malignancies and a number of autoimmune diseases. However, how anti-CD20 Abs operate in vivo to mediate B cell depletion is not fully understood. In particular, the anatomical location, the type

The bisphosphonates are synthetic compounds characterized by a P-C-P bond. They have a strong affinity to calcium phosphates and hence to bone mineral. In vitro they inhibit both formation and dissolution of the latter. Many of the bisphosphonates inhibit bone

The skeleton is a common site of breast carcinoma metastasis; 75% of patients with breast carcinoma demonstrate bone metastases at autopsy. The lytic destruction of bone in these patients is due to excessive osteoclastic activity. By reducing osteoclastic activity, bisphosphonates

Macrophages form an important cell population involved in numerous immunological processes. Techniques which eliminate these cells, in order to permit 'in vivo' studies of their function are generally imperfect and for that reason we have developed a method using the
