Geranylgeraniol - a new potential therapeutic approach to bisphosphonate associated osteonecrosis of the jaw.
Bisphosphonate associated osteonecrosis of the jaw (BP-ONJ) is one of the main side effects of bisphosphonate therapy (BPT). To date, there is no effective therapy of the BP-ONJ. Nitrogen-containing bisphosphonates (N-BPs) are particularly able to inhibit pyrophosphate synthase (FPPS) in the mevalonate pathway (MVP). Consequent of decreased synthesis of the metabolite Geranylgeraniol (GGOH) is believed to largely account for the development of BP-ONJ. Negative effect of N-BPs could be shown, resulting in decreased viability and migration capacity of different cell types of hard and soft tissues such as osteoblasts, fibroblast und endothelial cells. Aim of our in vitro study was to demonstra…
Exchange-coupled Fe-X-Fe model compounds for certain iron proteins
X-ray structure studies, Mossbauer experiments and magnetic susceptibility measurements were used in connection with molecular orbital calculations to monitor structurally induced changes of electronic and magnetic properties in exchangecoupled [Fe2S2 (SR)4]2- and [Fe2OCl6]2- anions.
