Description

Application

Etidronate disodium hydrate has been used in the synthesis of bisphosphonate derivatives of adenosine triphosphate (ATP)by T4 RNA ligase. It has also been sued to inhibit human farnesyl diphosphate synthase (FDPS).

Biochem/physiol Actions

Bisphosphonate antiresorptive agent. Less potent inhibitor of farnesyl diphosphate synthase (IC₅₀ = 80 μM) as compared to the nitrogen containing bisphosphonates

Etidronate helps to guard chronic ocular hypertension prompted retinal oxidative stress. It stimulates the development of retinal ganglion cells through insulin-like growth factor 1 (IGF-1) signaling pathway. It may possess neuroprotective effects in in vivo and in vitro rat model of glaucoma. Etidronate belongs to bisphosphonates.

Uptake of gold (III) from waste gold solution onto biomass-based adsorbents organophosphonic acid functionalized spent buckwheat hulls.

Ping Yin et al.

Bioresource technology, 128, 36-43 (2012-12-01)

Novel biomass-based adsorbents organophosphonic acid functionalized spent buckwheat hulls (OPA-BH) with 60 mesh were successfully employed to adsorb Au(III) ions from simulated wastewater. The adsorption kinetics and isotherms both in unary ion system and in ternary ions system were investigated

Randomized, double-blinded, placebo-controlled, trial of risedronate for the prevention of bone mineral density loss in nonmetastatic prostate cancer patients receiving radiation therapy plus androgen deprivation therapy.

Richard Choo et al.

International journal of radiation oncology, biology, physics, 85(5), 1239-1245 (2012-12-26)

Androgen deprivation therapy (ADT) has been used as an adjuvant treatment to radiation therapy (RT) for the management of locally advanced prostate carcinoma. Long-term ADT decreases bone mineral density (BMD) and increases the risk of osteoporosis. The objective of this
