  Thienopyrimidine Bisphosphonate (ThPBP) Inhibitors of the Human Farnesyl Pyrophosphate Synthase: Optimization and Characterization of the Mode of Inhibition

  摘要：

  Human farnesyl pyrophosphate synthase (hFPPS) controls the post-translational prenylation of small GTPase proteins that are essential for cell signaling, cell proliferation, and osteoclast-mediated bone resorption. Inhibition of hFPPS is a clinically validated mechanism for the treatment of lytic bone diseases, including osteoporosis and cancer related bone metastases. A new series of thienopyrimidine-based bisphosphonates (ThP-BPs) were identified that inhibit hFPPS with low nanomolar potency. Crystallographic evidence revealed binding of ThP-BP inhibitors in the allylic subpocket of hFPPS. Simultaneous binding of inorganic pyrophosphate in the IPP subpocket leads to conformational closing of the active site cavity. The ThP-BP analogues are significantly less hydrophilic yet exhibit higher affinity for the bone mineral hydroxyapatite than the current N-BP drug risedronic acid. The antiproliferation properties of a potent ThB-BP analogue was assessed in a multiple myeloma cell line and found to be equipotent to the best current N-BP drugs. Consequently, these compounds represent a new structural class of hFPPS inhibitors and a novel scaffold for the development of human therapeutics.

  Post-translational prenylation of the small GTP-binding proteins (GTPases) is vital to a plethora of biological processes, including cellular proliferation. We have identified a new class of thienopyrimidine-based bisphosphonate (ThP-BP) inhibitors of the human geranylgeranyl pyrophosphate synthase (hGGPPS) that block protein prenylation in multiple myeloma (MM) cells leading to cellular apoptosis. These inhibitors are also effective in blocking the proliferation of other types of cancer cells. We confirmed intracellular target engagement, demonstrated the mechanism of action leading to apoptosis, and determined a direct correlation between apoptosis and intracellular inhibition of hGGPPS. Administration of a ThP-BP inhibitor to a MM mouse model confirmed in vivo down regulation of Rap 1A geranylgeranylation and reduction of monoclonal immunoglobulins (M-protein, a biomarker of disease burden) in the serum. These results provide the first proof-of-principle that hGGPPS is a valuable therapeutic target in oncology and more specifically for the treatment of multiple myeloma.
