Zoonotic poxvirus infections in humans

Purpose of review The 2003 USA monkeypox epidemic caused by imported African rodents, newly emergent poxvirus zoonoses in Brazil and the possible use of variola virus for biological warfare has led to renewed interest in poxviruses and anti-poxviral therapies. Increasing foreign travel and importation of exotic animal species increases the likelihood of poxvirus infections occurring outside their usual geographical range and diagnostic delay has important implications. The present review provides an overview of these rare zoonoses. Recent findings Three genera of Poxviridae are known to cause human zoonoses: orthopoxviruses, parapoxviruses and yatapoxvirus. Most cases are occupational, sporadic and have few cutaneous lesions with low morbidity. The exception is monkeypox, similar to smallpox, with significant morbidity and childhood mortality. Molecular characterization using polymerase chain reaction (PCR) amplification and other methods provides accurate phylogenetic identification and suggests that a cowpox-like virus is the probable ancestor of variola and other zoonotic poxviruses. DNA genomic sequencing of the Brazilian Cantagalo and Aracatuba viruses shows a close relationship to vaccinia virus. Poxviruses have potential in cancer immunotherapy and their ability to evade host-cell immune responses may provide a basis for new antipoxvirus therapies. Other agents, particularly nucleoside phosphonates such as cidofovir, show therapeutic action against poxviruses. Summary Human zoonotic poxvirus infections are rare but increasingly encountered outside their usual geographical range. The 2003 USA monkeypox outbreak emphasizes the importance of early accurate diagnosis, particularly because increasing numbers of immunosuppressed individuals increases the potential for severe or fatal infections. Pi methodology enables accurate phylogenetic typing and has identified new diseases, but rapid, reliable methods must be made available for clinicians. More research into therapeutic agents for the prevention and treatment of poxvirus infections is required.

A theoretical study of the aromaticity of hypervalent sulfur heterocycles

In this paper we report on the heteroaromaticity of 1,2,5-thiadiazole-1,l-dioxide (I) and its isomers 1,2,4-thiadiazole-1,1-dioxide (II), 1,3,4-thiadiazole-1,I-dioxide (III) and 1,2,3-thiadiazoIe-1,1-dioxide (IV) by calculating their electronic structures and estimating their aromatic character in terms of our previously developed criteria: N, MDQ, Delta E-pi L(NLMO) and Delta E-pi L(Boys) as well as comparing their total energies. (I) is shown to be the most aromatic isomer in good agreement with chemical reasoning and experimental evidence. The 1,l-dioxides of thiazole and isothiazole were predicted to be intermediate in aromaticity between thiophene-l, 1-dioxide and the isomers, (I)-(N). N value measures indicate that thiophene-l,1-dioxide would retain a small measure of aromatic character relative to thiophene (N(thiophene) = 0.868, N(thiophene-l,l-dioxide) = 0.389).

The 5-hydrazino-3-methylisothiazole-4-carboxylic acid, its new 5-substituted derivatives and their antiproliferative activity

Currently, the basic method of treatment of colon cancer is surgery. The range of anticancer drugs used in the treatment of colorectal cancer is small and is based mainly on systemic combination chemotherapy. As a result of the designed syntheses, we received new isothiazole derivatives with anticancer activity. The synthesized 5-hydrazino-3-methylisothiazole-4-carboxylic acid has never been obtained before. It is also a substrate for the synthesis of its innovative derivatives, i.e. compounds that are Schiff bases. The identification of the structure of new compounds was carried out using mass spectrometry (MS), proton nuclear magnetic resonance spectroscopy (H-1 NMR), carbon nuclear magnetic resonance spectroscopy (C-13 NMR) and infrared spectroscopy (IR). Potential antitumor activity was confirmed in antiproliferative MTT and SRB tests. The selected, most biologically active substances were characterized by high selectivity towards leukemia and colon cancer cell lines. They caused high inhibition of proliferation of human biphenotypic B cell myelomonocytic leukemia MV4-11 (13 compounds), human colon adenocarcinoma cell lines sensitive LoVo (8 compounds) and resistant to doxorubicin LoVo/DX (12 compounds). However, in the conducted studies, their activity against breast adenocarcinoma MCF-7 and normal non-tumorigenic epithelial cell line derived from mammary gland MCF-10A was substantially lower. The result of this work is claimed Polish patent application.

Conversion of pyrroles into bi-1,2,5-thiadiazoles: a new route to biheterocycles

Trithiazyl trichloride 1 converts 1,2,5-triphenylpyrrole 5 into its 3,4-dichloro derivative together with the isothiazole imine 6 and the imine hydrolysis product, the ketone 3. The best yield of the isothiazole 6 is obtained in the presence of 4 Angstrom molecular sieves (Table 1). Conversion of the pyrrole 5 into the isothiazole 6 is exactly analogous to the reaction of 1 with 2,5-diphenyl-furan and -thiophene. Other N-aryl and the related 2,5-diphenylpyrroles 8 give similar results (Table 2). However, 1-methyl-2,5-diphenylpyrrole 11 reacts with 1 in an entirely different way to give 4,4′-diphenyl-3,3′-bi-1,2,5-thiadiazole 12, in which two thiadiazole rings have been fused onto the pyrrole and the CH3N unit has been excised as HCN. The same product 12 is formed, In similar yields, by reaction of 1 with 1,4-diphenylbuta-1,3-diyne and 1,4-diphenylbut-1-en-3-yne. Other N-alkyl 2,5-diphenylpyrroles 16 react similarly (Table 3), giving the best yield (70%) of bi-thiadiazole 12 in the presence of 4 Angstrom molecular sieves (Table 4). 1-Methyl- and 1-ethyl-3,4-dibromo-2,5-diphenylpyrrole also give 12, together with 3-(benzoyldichloromethyl)-4-phenyl-1,2,5-thiadiazole 21 in high combined yield. The formation of bi-1,2,5-thiadiazole 12 from N-alkylpyrroles represents a new dissection of the pyrrole ring and a new and very short route to an aromatic biheterocyclic system. Mechanisms which rationalise the different pathways observed are proposed for all of these reactions.

Synthesis of omega-(1,1,3-trioxo-1,3-dihydrobenzo[d] isothiazol-2-yl)-alkanecarboxylic acids: conventional versus microwave heating

The alkylation of sodium saccharin with alkyl halides to produce the intermediates.-( 1,1,3-trioxo-1,3-dihydrobenzo[d]isothiazol-2-yl)-alkanecarboxylic acids can be markedly improved by using microwave irradiation, both in terms of product yield and reaction time. While the process produces high yields with halo esters and halonitriles, the reaction with haloacids, which proceeds smoothly by conventional reflux, gives poorer yields with microwaves. This is due to an acid-base equilibrium produced by the rapid heating of the mixture under irradiation. Esters and nitriles can be converted into the acids by acid hydrolysis, without appreciable loss of the 1,1,3-trioxo-1,3-dihydrobenzo[ d] isothiazole ring.

High-resolution infrared analysis of seven fundamental bands of gaseous isothiazole between 750 and 1500 cm(-1)

The gas phase IR spectrum of isothiazole, C3H3NS, between 550 and 1700 cm(-1) was recorded with a resolution of ca. 0.003 cm (-1). The rotational structure of seven fundamental bands in the region 750-1500 cm-1 has been assigned and analysed by the Watson Hamiltonian model. A number of local resonances in the bands have been identified and explained qualitatively in terms of Coriolis interactions. For each band upper state spectroscopic constants, including band center, rotational constants, and quartic centrifugal distortion constants are given. From observed crossings due to resonances we locate the weak bands v(9)(A’) and v(13)(A’) at 1041.9(2) and 642.0(3) cm(-1) respectively. The anharmonic frequencies have been determined using a cc-pVTZ basis set, at the MP2 and B3LYP levels; the two theoretical methods give very similar results for rotational constants, anharmonic band center frequencies and distortion constants, and many of these are in good agreement with experiment.

Ruthenium(II) Complexes of Isothiazole Ligands: Crystal Structure, HSA/DNA Interactions, Cytotoxic Activity and Molecular Docking Simulations

Two new neutral ruthenium(II) complexes [Ru(eta(6)-p-cymene)Cl-2(1)] (3) and [Ru(eta(6)-p-cymene)Cl-2(2)] (4) (1=5-(phenylamino)-3-pyrrolidin-1-ylisothiazole-4-carbonitrile;2=3-morpholin-4-yl-5-(phenylamino)isothiazole-4-carbonitrile) have been synthesized and characterized using elemental analysis, IR, UV-Vis and NMR spectroscopy. The crystal structure was confirmed for complex3and both ligands. Examination of the interactions of ligands and complexes with CT-DNA (Calf Thymus DNA), as well as with HSA (Human Serum Albumin) revealed that ligands and complexes could interact with CT-DNA through intercalation and could bind strongly with HSA. Docking experiments toward DNA dodecamer indicate excellent accordance with experimental Delta G values. The cytotoxic activity of ligands and complexes was evaluated by MTT assay against HCT116 and HeLa tumoral cells. The complexes3and4showed good activity and selectivity on HCT116 cells. Neither of the tested compounds shows cytotoxic activity against a healthy MRC-5 cell line. Flow cytometry analysis showed the apoptotic death of the HCT116 cells with a cell cycle arrest in the S-phase.

Theoretical Study of Kinetics and Thermodynamics of Hetero Diels-Alder Reaction of Thiazole and Isothiazol with Thiophene-2,5-dione

DFT methods have been used to study the hetero Diels-Alder reaction of thiazole and isothiazole with thiophen-2,5-dione. The thermodynamic and kinetic parameters were calculated. The relative stabilities of the transition structures corresponding to the endo/exo stereoisomers have been rationalized on the basis of the secondary molecular orbital interactions. NBO analysis was carried out to calculate the synchronicity index. It was shown that all reactions are synchronous. A HOMO-LUMO energy gap shows both reactions are normal electron demand.
