  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.

  (hFPPS). Analogs were prepared via cyclization of 2-(1-(trimethylsilyl)ethylidene)malononitrile to 2-amino-4-(trimethylsilyl)thiophene-3-carbonitrile in the presence of elemental sulfur. Direct ipso-iododesilylation of this intermediate led to selective iodination at Cβ of the sulfur atom in high efficiency. The synthetic protocols developed were used in the parallel synthesis of structurally diverse thieno[2
