NE 10790, a poor farnesyl pyrophosphate synthase inhibitor, is a phosphonocarboxylate analogue of the potent bisphosphonate risedronate and is a weak antiresorptive agent.
NE 10790 inhibits incorporation of [14C]mevalonic acid into Rab6, but not into H-Ras or Rap1, proteins that are modified by FTase and GGTase I, respectively. NE 10790 reduces viability in J774 cells. NE 10790 prevents prenylation of 22-26-kDa proteins that are not modified by FTase or GGTase I[1].
