  Effects of Bisphosphonates on the Growth of Entamoeba histolytica and Plasmodium Species in Vitro and in Vivo

  摘要：

  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.

  Using the structure of (3,5-dichlorophenyl)aminomethylenebisphosphonic acid as a lead compound, 25 new phosphonates were synthesized and evaluated as possible inhibitors of Arabidopsis thaliana delta(1)-pyrroline-5-carboxylate (P5C) reductase. Derivatives substituted in the phenyl ring retained the inhibitory potential, though to a different extent. On the contrary any variation in the scaffold, i.e., the replacement of the second phosphonate moiety with a hydroxyl or an amino residue, resulted in a significant loss of biological activity. The availability of several structures capable of interfering with the catalytic mechanism in the micromolar to millimolar range allowed a proper structure-activity relationship analysis, leading us to hypothesize about the steric and electronic requirements for maintenance or enhancement of the inhibitory properties. Reversal experiments with suspension cultured cells provided evidence for the occurrence of enzyme inhibition in vivo. Because in higher plants the step catalyzed by P5C reductase is shared by all pathways leading to proline synthesis, these compounds may be exploited for the design of new substances endowed with herbicidal activity.

  Analogues of previously studied phenyl-substituted aminomethylene-bisphosphonic acids were synthesized and evaluated as inhibitors of Arabidopsis thaliana delta(1)-pyrroline-5-carboxylate reductase. With the aim of improving their effectiveness, two main modifications were introduced into the inhibitory scaffold: the aminomethylenebisphosphonic moiety was replaced with a hydroxymethylenebisphosphonic group, and the length of the molecule was increased by replacing the methylene linker with an ethylidene chain. In addition, chlorine atoms in the phenyl ring were replaced with various other substituents. Most of the studied derivatives showed activity in the rnicromolar to millimolar range, with two of them being more effective than the lead compound, with concentrations inhibiting 50% of enzyme activity as low as 50 mu M. Experimental evidence supporting the ability of these inhibitors to interfere with proline synthesis in vivo is also shown.
