  Highly Potent Geminal Bisphosphonates. From Pamidronate Disodium (Aredia) to Zoledronic Acid (Zometa)

  摘要：

  Bisphosphonates (BP) are pyrophosphate analogues in which the oxygen in P-O-P has been replaced by a carbon, resulting in a metabolically stable P-C-P structure. Pamidronate (1b, Novartis), a second-generation BP, was the starting point for extensive SAR studies. Small changes of the structure of pamidronate lead to marked improvements of the inhibition of osteoclastic resorption potency. Alendronate (1c, MSD), with an extra methylene group in the N-alkyl chain, and olpadronate (1h, Gador), the N,N-dimethyl analogue, are about 10 times more potent than pamidronate. Extending one of the N-methyl groups of olpadronate to a pentyl substituent leads to ibandronate (1k, Roche, Boehringer-Mannheim), which is the most potent close analogue of pamidronate. Even slightly better antiresorptive potency is achieved with derivatives having a phenyl group linked via a short aliphatic tether of three to four atoms to nitrogen, the second substituent being preferentially a methyl group (e.g., 4g, 4j, 5d, or 5r). The most potent BPs are found in the series containing a heteroaromatic moiety (with at least one nitrogen atom), which is linked via a single methylene group to the geminal bisphosphonate unit. Zoledronic acid (6i), the most potent derivative, has an ED50 of 0.07 mg/kg in the TPTX in vivo assay after sc administration. It not only shows by far the highest therapeutic ratio when comparing resorption inhibition with undesired inhibition of bone mineralization but also exhibits superior renal tolerability. Zoledronic acid (6i) has thus been selected for clinical development under the registered trade name Zometa. The results of the clinical trials indicate that low doses are both efficacious and safe for the treatment of tumor-induced hypercalcemia, Paget's disease of bone, osteolytic metastases, and postmenopausal osteoporosis.

  5-Substituted Imidazole-4-acetic Acid Analogues:  Synthesis, Modeling, and Pharmacological Characterization of a Series of Novel γ-Aminobutyric Acid_C Receptor Agonists

  摘要：

  A series of ring-substituted analogues of imidazole-4-acetic acid (IAA, 4), a partial agonist at both GABA(A) and GABA(C) receptors (GABA = gamma-aminobutyric acid), have been synthesized. The synthesized compounds 8a-1 have been evaluated as ligands for the alpha(1)beta(2)gamma(2S) GABA(A) receptors and the rho(1) GABA(C) receptors using the FLIPR membrane potential (FMP) assay and by electrophysiology techniques. None of the tested compounds displayed activity at the GABA(A) receptors at concentrations up to 1000 mu M. However, the 5-Me, 5-Ph, 5-p-Me-Ph, and 5-p-F-Ph IAA analogues, 8a,c,f,g, displayed full agonist activities at the rho(1) receptors in the FMP assay (EC50 in the range 22-420 mu M). Ligand-protein docking identified the Thr129 in the alpha(1) subunit and the corresponding Ser168 residue in rho(1) as determinants of the selectivity displayed by the 5-substituted IAA analogues. The fact that GABA, 4, and 8a displayed decreased agonist potencies at a rho(1)Ser168Thr mutant compared to the WT rho(1) receptor strongly supported this hypothesis. However, in contrast to GABA and 4, which exhibited increased agonist potencies at a alpha(1)(Thr129Ser)beta(2)gamma(2) mutant compared to WT GABA(A) receptor, the data obtained for 8a at the WT and mutant receptors were nonconclusive.
