Evidence that BP pretreatment of breast and prostate carcinoma cells inhibited tumor cell invasion in a dose-dependent manner is provided and BPs may be useful agents for the prophylactic treatment of patients with cancers that are known to preferentially metastasize to bone is suggested.

Bisphosphonates are the leading drugs for the treatment of osteoporosis. In randomized controlled trials (RCTs), alendronate, risedronate, and zoledronate have shown to reduce the risk of vertebral,…

Evidence is provided for a direct cellular effect of BP in preventing tumor cell adhesion to bone, suggesting that BPs may be useful agents for the prophylactic treatment of patients with cancer that is known to preferentially metastasize to bone.

N‐BPs, which inhibit bone resorption by preventing prenylation of small GTPases, unexpectedly cause the accumulation of GTP‐bound, unprenylated Rho family GTPase in macrophages and osteoclasts, causing inappropriate activation of downstream signaling pathways.

Structural analysis shows that the product length is constrained by a hydrophobic cavity formed primarily by a set of residues from the same subunit as the product as well as at least one other from the dimeric partner, and Plasmodium GGPP synthase (GGPPS) can bind nitrogen-containing bisphosphonates strongly with the energetically favorable cooperation of three Mg2+, resulting in inhibition by this class of compounds at IC50 concentrations below 100 nm.

Many of the first-, second- and third-generation bisphosphonates have been tested in a model of retinoid-induced bone resorption, and in this model the rank ordering of potency is similar, though somewhat larger doses of bisph phosphonate are required to block the Resorption induced by the retinoids.

There are substantial differences among BPs in their binding to HAP, which may be exploited in the development of biomaterials and may also partly explain the extent of their relative skeletal retention and persistence of biological effects observed in both animal and clinical studies.
