Digeranyl bisphosphonate (DGBP) is a potent geranylgeranylpyrophosphate (GGPP) synthase inhibitor, which inhibits geranylgeranylation of Rac1. In Vitro Digeranyl bisphosphonate (DGBP) impairs geranylgeranylation. To examine if Digeranyl bisphosphonate modulates Rac1 activity, cells are exposed to vehicle or Digeranyl bisphosphonate. Rac1 activation increases significantly after chrysotile exposure, whereas the activity in Digeranyl bisphosphonate -treated cells is reduced to control levels. Digeranyl bisphosphonate also decreases H 2 O 2 generation in chrysotile-exposed macrophages. MCE has not independently confirmed the accuracy of these methods. They are for reference only. In Vivo To further evaluate the effect of Digeranyl bisphosphonate (DGBP; 0.2 mg/kg/day) in protecting mice from chrysotile-induced pulmonary fibrosis, the mice are administered vehicle or Digeranyl bisphosphonate subcutaneously in osmotic pumps, and exposed to saline or chrysotile the following day. Mice exposed to saline have normal lung architecture with vehicle and Digeranyl bisphosphonate treatment. Chrysotile-exposed mice that receive vehicle have significant architectural changes in their lung parenchyma and large amounts of collagen deposition, whereas the lungs of the Digeranyl bisphosphonate -treated mice are essentially normal. To investigate the effect of Digeranyl bisphosphonate in Bleomycin-induced fibrosis, osmotic pumps containing either vehicle or Digeranyl bisphosphonate are implanted subcutaneously in WT mice. Mice are exposed to saline or Bleomycin the following day. Digeranyl bisphophonate (0.2 mg/kg/day)-treated mice show significantly less hydroxyproline compared to vehicle-treated mice exposed to Bleomycin . MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid IC50& Target:Rac1
