We have investigated the effects in vitro of a series bisphosphonates on proliferation Trypanosoma cruzi, brucei rhodesiense, Leishmania donovani, Toxoplasma gondii, and Plasmodium falciparum. The results show that nitrogen-containing type used bone resorption therapy significant activity against parasites, with aromatic species having some cases nanomolar or low-micromolar IC50 values parasite replication (e.g. o-risedronate, = 220 nM for T. rhodesiense; risedronate, 490 gondii). In...
Trypanothione reductase (TR) is both a valid and an attractive target for the design of new trypanocidal drugs. Starting from menadione, plumbagin, juglone, three distinct series 1,4-naphthoquinones (NQ) were synthesized as potential inhibitors TR Trypanosoma cruzi (TcTR). The parent molecules functionalized at carbons 2 and/or 3 by various polyamine chains. Optimization TcTR inhibition specificity versus human disulfide reductases was achieved with...
Artemisinin—the next generation: Efficacies of artemisone against the malaria parasite are substantially greater than those current artemisinin "gold standard", artesunate. Also, in contrast to most artemisinins it displays low lipophilicity and negligible neuro- cytotoxicity vitro vivo assays. Thus, drug offers promise for use artemisinin-based combination therapy.

The interaction of miltefosine with amphotericin B, sodium stibogluconate, paromomycin, and sitamaquine was assessed in vitro additionally for the first three combinations vivo. In interactions were indifferent combined B (mean sums fractional inhibitory concentrations [mean summation operatorFICs] ranging from 1.22 to 1.51 at 50% effective concentration [EC50] level 1.08 1.38 EC90 level), operatorFICs 1.33 1.0 1.02, respectively), paromomycin 0.79 0.93 EC50 0.77 1.35 level). Some synergy...
A method has been defined for infecting primary mouse peritoneal macrophages with amastigotes of Leishmania donovani in vitro, and analysing the response infected to treatment drugs. The growth intracellular was inhibited by all clinically used antileishmanial Toxic effects on were observed some Other experimental compounds active this system. This test is proposed as an initial screening discovery novel compounds.
The in-vitro activities of four anticancer alkyllysophospholipids, ET-18-OCH3 (edelfosine), hexadecylphosphocholine (miltefosine), ilmofosine and SRI 62-834, were determined with ED50 values for Leishmania donovani Trypanosoma cruzi amastigotes between 0.2 5.0 microM brucei trypomastigotes 7.0 50.8 microM. In BALB/c mice miltefosine the most active compounds 2.9 14.5 mg/kg x 5 doses against L. a suppressive effect on T. infections at 30 doses.
To combat drug resistance, new chemical entities are urgently required for use in next generation anti-malarial combinations. We report here the results of a medicinal chemistry programme focused on an imidazopyridine series targeting Plasmodium falciparum cyclic GMP-dependent protein kinase (PfPKG). The most potent compound (ML10) has IC
