  3-D QSAR研究双膦酸盐对利什曼原虫主要法呢基焦磷酸合酶的抑制作用。

  摘要：

  我们报告了作为利什曼原虫主要甲羟戊酸/异戊二烯生物合成途径酶，法呢基焦磷酸合酶的抑制剂的62二膦酸盐的活性。所研究的化合物具有约100 nM至约80 microM（相当于K（i）值低至10 nM）的活性（IC（50）值）。发现活性最高的化合物是唑来膦酸盐（据报道其单晶X射线结构），吡啶基-乙烷-1-羟基-1,1-双膦酸酯或吡啶甲基氨基亚甲基双膦酸酯。但是，N-脂环族氨基亚甲基双膦酸酯（如茚满膦酸酯）（N-环庚基氨基亚甲基双膦酸酯）以及含有短（n = 4、5）烷基链的脂族氨基亚甲基双膦酸酯也具有活性，IC（50）值在200-1700 nM范围内（对应于大约20-170 nM的K（i）值）。含有更长或多个（N，N-）烷基取代基的双膦酸酯是无活性的，环上缺少邻或间氮原子或具有多个卤素取代基或对氨基的芳香族化合物也是如此。为了将这些观察结果放在更定量的结构基础上，我们使用了三维定量结构-活性关系技

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

  Bisphosphonates (BP) are pyrophosphate analogues in which the oxygen in P-O-P has been replaced by a carbon, resulting in a metabolically stable P-C-P structure.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.
• Effects of Bisphosphonates on the Growth of <i>Entamoeba histolytica</i> and <i>Plasmodium </i>Species in Vitro and in Vivo

  The effects of a series of 102 bisphosphonates on the inhibition of growth of Entamoeba histolytica and Plasmodium falciparum in vitro have been determined, and selected compounds were further investigated for their in vivo activity. Forty-seven compounds tested were active (IC50 < 200 muM) versus E. histolytica growth in vitro. The most active compounds (IC50 similar to 4-9 muM) were nitrogen-containing bisphosphonates with relatively large aromatic side chains. Simple n-alkyl-1-hydroxy-1,1-bisphosphonates, known inhibitors of the enzyme farnesylpyrophosphate (FPP) synthase, were also active, with optimal activity being found with C9-C10 side chains. However, numerous other nitrogen-containing bisphosphonates known to be potent FPP synthase inhibitors, such as risedronate or pamidronate, had little or no activity. Several pyridine-derived bisphosphonates were quite active (IC50 similar to 10-20 muM), and this activity was shown to correlate with the basicity of the aromatic group, with activity decreasing with increasing pK(a) values. The activities of all compounds were tested versus a human nasopharyngeal carcinoma (KB) cell line to enable an estimate of the therapeutic index (TI). Five bisphosphonates were selected and then screened for their ability to delay the development of amebic liver abscess formation in an E. histolytica infected hamster model. Two compounds were found to decrease liver abscess formation at 10 mg/kg ip with little or no effect on normal liver mass. With P. falciparum, 35 compounds had IC50 values <200 muM in an in vitro assay. The most active compounds were also simple n-alkyl-1-hydroxy-1,1-bisphosphonates, having IC50 values around 1 muM. Five compounds were again selected for in vivo investigation in a Plasmodium berghei ANKA BALB/c mouse suppressive test. The most active compound, a C9 n-alkyl side chain containing bisphosphonate, caused an 80% reduction in parasitemia with no overt toxicity. Taken together, these results show that bisphosphonates appear to be useful lead compounds for the development of novel antiamebic and antimalarial drugs.
