Novel bisphosphonate inhibitors of the human farnesyl pyrophosphate synthase
摘要:
A structure-based approach was pursued in designing novel bisphosphonate inhibitors of the human farnesyl pyrophosphate synthase (hFPPS). Preliminary SAR and structural evidence for the simultaneous binding of these inhibitors into the isopentenyl pyrophosphate (IPP) and the geranyl pyrophosphate (GPP) substrate sub-pockets of the enzyme are presented.

Human farnesyl pyrophosphate synthase (hFPPS) controls intracellular levels of FPP and post-translational prenylation of small GTPase proteins, which are essential for cell signaling and cell proliferation. Clinical investigations provide evidence that N-BP inhibitors of hFPPS are disease modifying agents that improve survival of multiple myeloma (MM) patients via mechanisms unrelated to their skeletal effects. A new series of N-BPs was designed that interact with a larger portion of the GPP subpocket, as compared to the current therapeutic drugs, and rigidify the (KRRK367)-K-364 tail of hFPPS in the closed conformation in the absence of IPP. An analogue of this series was used to demonstrate inhibition of the intended biological target, resulting in apoptosis and down-regulation of ERK phosphorylation in human MM cell lines.
