In an effort to develop alternative drugs for the treatment of giardiasis our research group has synthesized and evaluated a novel nitazoxanide and N-methyl-1H-benzimidazole hybrid molecule, named CMC-20. It showed an IC50 of 0.010 muM on Giardia intestinalis, lower than the IC50 values of 0.015, 0.037 and 1.224 muM for nitazoxanide, albendazole and metronidazole, respectively. In addition, we report studies carried out on its mechanism of action and effect at the ultrastructural level on G. intestinalis. The proteomic analysis of trophozoites treated with CMC-20 revealed significant changes in the expression level of proteins of the cytoskeleton, alpha and beta tubulin, alpha-1, beta giardin and axoneme-associated protein, among other molecules. Ultrastructural studies demonstrated that CMC-20 induces morphological changes on the parasite that loses its characteristic pear shape. Uncommon large bulbous structure at the flagella end, and parasites showing flange membrane bending and a concave depression in the ventral region, resembling an encystation process, were also observed. In addition, some apoptotic and autophagic-like features, such as membrane blebbing, intense vacuolation, chromatin condensation and multilamellar bodies were detected. Phosphatidylserine externalization was determined as an apoptotic marker by flow cytometry and immunofluorescence microscopy; however, a typical ladder-like DNA fragmentation profile was not detected. Although it was found that CMC-20 triggers the encystation process, damage to the cyst wall indicates loss of viability.

A series of Cu(II), Fe(III), Pb(II), Mn(II) metals complexes have been synthesized with the new thiazole azo dye containing tridentate [N.N.O] donor ligand 2-[2–(5-nitro thiazolyl) azo]-4-methyl-5-nitro phenol (5-NTAMNP) derived from 2-amino-5-nitrothiazole and 3-methyl-4-nitrophenol by the diazotization operation and the adizonium chloride salt solution of 2-amino-5-nitrothiazole reacting with 3-methyl-4-nitrophenol as a coupling compound in alkaline alcoholic solution. The structures of synthesized novel ligand was identified and confirmed via resorting to various spectroscopic techniques which included, 1H NMR, Mass spectrum, UV-visible, Fourier-transform infrared (FTIR), X-Rays diffraction (XRD), the surface nature and morphology and size average and elemental composition of individual ligand particles were examined using a field emission scanning electron microscope (FESEM) coupled with an energy dispersive X-ray system (EDX), in addition to above the physical properties of ligand have been studied via check its melting point and the purity of the ligand also was checked by TLC in presence of a certain solvent system. As for the consistency positions available in (5-NTAMNP) and the manner of its association with these metallic ions it’s likely that the pattern of complexity as a tridentate chelating agent with the formation of a coordination number for all metallic ions found equal to six and have Octahedral shape for all metallic ion. The optimal condition for complexation have been studied, the prepared metallic complexes were identified via UV-visible & FT-IR spectra. All metallic complex and (5-NTAMNP) ligand were screened for their biological activities.

In ?-proteobacteria and Actinomycetales, cysteine biosynthetic enzymes are indispensable during persistence and become dispensable during growth or acute infection. The biosynthetic machinery required to convert inorganic sulfur into cysteine is absent in mammals; therefore, it is a suitable drug target. We searched for inhibitors of Salmonella serine acetyltransferase (SAT), the enzyme that catalyzes the rate-limiting step of l-cysteine biosynthesis. The virtual screening of three ChemDiv focused libraries containing 91 ?243 compounds was performed to identify potential SAT inhibitors. Scaffold similarity and the analysis of the overall physicochemical properties allowed the selection of 73 compounds that were purchased and evaluated on the recombinant enzyme. Six compounds displaying an IC50 <100 muM were identified via an indirect assay using Ellman's reagent and then tested on a Gram-negative model organism, with one of them being able to interfere with bacterial growth via SAT inhibition.

In this paper we report a synthesis of a series of nonlinear optical donor-acceptor chromophores, derivatives of bisphenol A. The studied compounds contain azo bonds with substituted thiazole ring as side groups. Their molecular first hyperpolarizablities were measured by solvatochromic method. The experimental values were compared with the results of semi-empirical calculations. The structures of obtained compounds were confirmed by infrared, 1H NMR and ultraviolet spectroscopy. Design of nonlinear-optical polymers with included chromophores was also performed.

The solvatochromism and other spectroscopic and photophysical characteristics of four azo disperse dyes, derived from 2-amino-5-nitrothiazole, were evaluated and interpreted with the aid of experimental data and quantum mechanical calculations. For the non-substituted compound two conformers, E and Z, were proposed for the isolated molecules, being the second one considerably less stable. The optimization of these structures in combination with a SCRF methodology (IEFPCM, simulating the molecules in a continuum dielectric with characteristics of methanol), suggests that the Z form is not stable in solution. This same behaviour is expected for the substituted compounds, which is corroborated by experimental data presented in previous investigations [A.E.H. Machado, L.M. Rodrigues, S. Gupta, A.M.F. Oliveira-Campos, A.M.S. Silva, J. Mol. Struct. 738 (2005) 239-245]. For the substituted compounds, two forms derived from E conformer (A and B) are possible. Quantum mechanical data suggest for the isolated molecules, that the low energy absorption band of the E conformers involve at least two close electronic states, having the low-lying excited state a 1(n,pi*) nature, and being the S2 state attributed to a 1(pi,pi*) transition. The data also suggest a small energy gap between the absorption peaks of A and B, related to the easy conversion between these forms. For the structures optimized in combination with the applied SCRF methodology, an states inversion is observed for the substituted compounds, with a considerable diminish of the energy gap between A and B absorption peaks. The electronic spectra of these compounds are quite sensitive to changes in the solvent polarity. The positive solvatochromism is more evident in aprotic solvents, probably due to the polarization induced by the solute. These compounds do not fluoresce at 298 K, but present a small but perceptible fluorescence at 77 K, which seems to be favoured by the nature of the group in the 2?-position of the phenyl ring. Moreover, such compounds present expressive values for first hyperpolarizability, which implies in good non-linear optics (NLO) responses and photoswitching capability.

Amixicile is a promising derivative of nitazoxanide (an antiparasitic therapeutic) developed to treat systemic infections caused by anaerobic bacteria, anaerobic parasites, and members of the Epsilonproteobacteria (Campylobacter and Helicobacter). Amixicile selectively inhibits pyruvate-ferredoxin oxidoreductase (PFOR) and related enzymes by inhibiting the function of the vitamin B1 cofactor (thiamine pyrophosphate) by a novel mechanism. Here, we interrogate the amixicile scaffold, guided by docking simulations, direct PFOR inhibition assays, and MIC tests against Clostridium difficile, Campylobacter jejuni, and Helicobacter pylori. Docking simulations revealed that the nitro group present in nitazoxanide interacts with the protonated N4?-aminopyrimidine of thiamine pyrophosphate (TPP). The ortho-propylamine on the benzene ring formed an electrostatic interaction with an aspartic acid moiety (B456) of PFOR that correlated with improved PFOR-inhibitory activity and potency by MIC tests. Aryl substitution with electron-withdrawing groups and substitutions of the propylamine with other alkyl amines or nitrogen-containing heterocycles both improved PFOR inhibition and, in many cases, biological activity against C. difficile. Docking simulation results correlate well with mechanistic enzymology and nuclear magnetic resonance (NMR) studies that show members of this class of antimicrobials to be specific inhibitors of vitamin B1 function by proton abstraction, which is both novel and likely to limit mutation-based drug resistance.

We designed and synthesized five new 5-nitrothiazole-NSAID chimeras as analogues of nitazoxanide, using a DCC-activated amidation. Compounds 1?5 were tested in vitro against a panel of five protozoa: 2 amitochondriates (Giardia intestinalis, Trichomonas vaginalis) and 3 kinetoplastids (Leishmania mexicana, Leishmania amazonensis and Trypanosoma cruzi). All chimeras showed broad spectrum and potent antiprotozoal activities, with IC50 values ranging from the low micromolar to nanomolar order. Compounds 1?5 were even more active than metronidazole and nitazoxanide, two marketed first-line drugs against giardiasis. In particular, compound 4 (an indomethacin hybrid) was one of the most potent of the series, inhibiting G. intestinalis growth in vitro with an IC50 of 0.145?muM. Compound 4 was 38-times more potent than metronidazole and 8-times more active than nitazoxanide. The in vivo giardicidal effect of 4 was evaluated in a CD-1 mouse model obtaining a median effective dose of 1.709?mug/kg (3.53?nmol/kg), a 321-fold and 1015-fold increase in effectiveness after intragastric administration over metronidazole and nitazoxanide, respectively. Compounds 1 and 3 (hybrids of ibuprofen and clofibric acid), showed potent giardicidal activities in the in vitro as well as in the in vivo assays after oral administration. Therefore, compounds 1?5 constitute promising drug candidates for further testing in experimental chemotherapy against giardiasis, trichomoniasis, leishmaniasis and even trypanosomiasis infections.

You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.121-66-4, Name is 5-Nitrothiazol-2-amine, molecular formula is C3H3N3O2S.

Histomonosis is a parasitic disease of poultry with worldwide prevalence. The disease can cause morbidity and mortality in chicken and turkey flocks entailing severe economic losses. In the first half of the last century, there was a high demand to control histomonosis as the turkey industry was severely affected by the disease. Consequently, numerous chemical compounds were tested for their efficacy against Histomonas meleagridis with varying outcomes, that are summarized and specified in this review. At the same time, preliminary attempts to protect birds with cultured histomonads indicated the possibility of vaccination. Several years ago antihistomonal drugs were banned in countries with tight regulations on pharmaceuticals in order to comply with the demand of consumer protection. As a consequence, outbreaks of histomonosis in poultry flocks increased and the disease became endemic again. New approaches to prevent and treat histomonosis are, therefore, needed and recently performed studies focused on various areas to combat the disease, from alternative chemotherapeutic substances to plant-derived compounds until vaccination, altogether reviewed here. Considering existing regulations and the overall outcome of experimental studies, it can be concluded that vaccination is very promising, despite the fact that various challenges need to be addressed until the first ever developed vaccine based upon live flagellates in human or bird medicine can be marketed.
