High-resolution infrared and theoretical study of four fundamental bands of gaseous 1,3,4-oxadiazole between 800 and 1600 cm(-1)

The Fourier transform infrared spectrum of gaseous 1,3,4-oxadiazole, C2H2N2O, has been recorded in the 800-1600 cm(-1) wavenumber region with a resolution around 0.0030 cm(-1). The four fundamental bands v(9)(B-1; 852.5 cm(-1)), V]4(B-2; 1078.5 cm(-1)), v(4)(A(1); 1092.6 cm(-1)), and v(2)(A(1); 1534.9 cm(-1)) are analyzed by the standard Watson model. Ground state rotational and quartic centrifugal distortion constants are obtained from a simultaneous fit of ground state combination differences from three of these bands and previous microwave transitions. Upper state spectroscopic constants are obtained for all four bands from single band fits using the Watson model. The v(4) and v(14) bands form a c-Coriolis interacting dyad, and the two bands are analyzed simultaneously by a model including first and second order Coriolis resonance using the ab initio predicted Coriolis coupling constant zeta(c)(14,4) . An extended local resonance in v(2) is explained as higher order b-Coriolis type resonance with v(6) + v(10), which is further perturbed globally by the v(15) + v(10) level. A fit of selected low-J transitions to a triad model including v(2)(A(1)), v(6) + v(10)(B-1), and v(15) + v(10)(A(2)) using an ab initio calculated Coriolis coupling constant zeta(c)(15,6) is performed. The rotational constants, ground state quartic centrifugal distortion constants, anharmonic frequencies, and vibration-rotational constants (alpha-constants) predicted by quantum chemical calculations using a cc-pVTZ and TZ2P basis with B3LYP methodology, are compared with the present experimental data, where there is generally good agreement. A complete set of anharmonic frequencies and alpha-constants for all fundamental levels of the molecule is given. (c) 2007 Elsevier Inc. All rights reserved.

Synthesis of novel isothiazolopyridines and their in vitro evaluation against Mycobacterium and Propionibacterium acnes

In this paper we describe synthesis, structures and some physicochemical properties of 20 isothiazolopyridines 8-13 substituted differently into an isothiazole ring as well as their in vitro antibacterial assays against Mycobacterium tuberculosis H37Rv, Mycobacterium fortuitum PCM 672 and Propionibacterium acnes PCM 2400. Compound 13a was found to be the most active derivative against M. tuberculosis H37Rv, demonstrating 100% growth inhibition of microorganisms in the primary screen (minimum inhibitory concentration [MIC] 6.25 mu g/mL). Nineteen of the prepared compounds were evaluated against M. fortuitum PCM 672 and P. acnes PCM 2400 and only compounds 9 and 12d exhibited excellent activity against individual strains of microorganisms with MIC90 <1 mu g/mL. The inhibitory action of the remaining isothiazolopyridines towards the tested strains of the microorganism was low, absent, or a non-linear correlation prohibited accurate determination of MIC values. Unexpectedly, seven of the remaining isothiazolopyridines tested against M. fortuitum and P. acnes stimulated growth of the microorganisms in the range 10-50% or even more (10b) under experimental conditions.

Synthesis and biological activity of 4-amino-1-methyl-5-imidazolecarboxylic acid derivatives

The main goal of our study was the synthesis and biological evaluation of 4-amino- and 4-[(4-chlorobenzoyl)amino]-1-methylimidazole N-substituted 5-carboxamides. Biological in vitro tests indicated their remarkable influence on some cellular immune and inflammatory responses compared with ibuprofen and leflunomide as reference drugs. The toxicity of the tested compounds on murine bone marrow cells was also determined. The anti-inflammatory activity of 4-[(4-chlorobenzoyl)amino]-5-[N-(4-chlorophenyl)]-1-methyl-5-imidazolecarboxamide (7a) was confirmed in vivo in the carrageenan-induced oedema test. Comparison of the biological activity of 7a with that of the isosteric isothiazole derivative MR-2/94 suggests that replacement of the isothiazole core ring system with an imidazole one resulted in a considerable lowering of toxicity while maintaining anti-inflammatory and immunotropic properties.

Combined Testing Approach to Evaluate the Antifungal Efficiency of Clove (Eugenia caryophyllata) Essential Oil for Potential Application in Wood Conservation

The efficiency of clove (Eugenia caryophyllata) essential oil (C-EO) for the curative antifungal treatment of historic wood was investigated in comparison with two classical biocide products: a boron-based preservative (Diffusit S) and a formulation containing quaternary ammonium salts and isothiazole (Biotin T). A combined approach was adopted that consisted of implementation of C-EO in a practical case study on a degraded beech (Fagus sylvatica) wood artifact and evaluation of the treatment efficacy via an original laboratory mycological test. Small samples, extracted from the degraded wood material before and after curative treatments, were placed as inoculum on sterile culture medium and incubated for periodic monitoring of the emerging fungal growth for 140 d. Direct observation was supplemented with digital quantification of the fungal coverage area via ImageJ software and calculation of the absolute and relative indices of fungal development reduction. The results indicated that the C-EO solutions at both tested concentrations (10%, 5%) were more efficient than the considered reference products at similar concentrations (Diffusit S (10%) and Biotin T (5%)) for curative antifungal treatment. However, none of the treatments applied entirely prevented reactivation of the severe and complex fungal attack, which was highlighted by the mycological tests conducted on the control samples.

THE PREPARATION OF 1,2,3,5-DITHIADIAZOLIUM CHLORIDES FROM THE REACTION OF NITRILE SULFIDES WITH THIAZYL CHLORIDE

Adamantyl-1,3,4-oxathiazol-2-one has been prepared for the first time and from it l-adamantyl nitrile sulphide has been generated. Characterisation data are presented, including the X-Ray crystal structure of the oxathiazolone. (Crystal data for C12H15NO2S: monoclinic, space group P2(1)/c, a = 11.334(2) Angstrom, b = 7.344(1) Angstrom, c = 14.373(2) Angstrom, beta = 107.74(1)degrees, V = 1139.5(3) Angstrom(3), Z = 4, R = 0.042). The planar heterocyclic ring is similar to structures observed in the gas phase for other oxathiazolone derivatives. The nitrile sulphide was reacted with dimethyl-acetylene dicarboxylate in situ to give an isothiazole derivative. The X-Ray crystal structure of 3-adamantyl-4,5-bis(methoxycarbonyl)-isothiazole has been obtained. (Crystal data for C17H21NO4S: monoclinic, space group P2(1)/n, a = 7.305(4) Angstrom, b = 7.339(4) Angstrom, c = 31.552(4) Angstrom, beta = 92.75(3)degrees, V = 1690(1) Angstrom(3), Z = 4, R = 0.079). A general cycloaddition reaction was discovered between the nitrile sulphides and thiazyl chloride to give 1,2,3,5-dithiadiazolium chlorides. The structure of the new 4-adamantyl-1,2,3,5-dithiadiazolium chloride was confirmed by reduction to the 4-adamantyl-1,2,3,5-dithiadiazolyl for which the X-Ray crystal structure has been determined. (Crystal data for C11H15N2S2: monoclinic, space group C2, a = 10.284(4) Angstrom, b = 8.651(2) Angstrom, c = 13.669(2) Angstrom, beta = 112.83(1)degrees, V = 1120.9(4) Angstrom(3), Z = 4, R = 0.042).

A Mixture ofD-Amino Acids Enhances the Biocidal Efficacy of CMIT/MIT Against CorrosiveVibrio harveyiBiofilm

Biocides are widely used for the mitigation of microbial contamination, especially in the field of the aviation fuel industry. However, the long-term use of biocide has raised the concerns regarding the environmental contamination and microbial drug resistance. In this study, the effect of a mixture ofD-amino acids (D-tyrosine andD-methionine) on the enhancement of the bactericidal effect of 5-Chloro-2-Methyl-4-isothiazolin-3-one/2-Methyl-2H-isothiazole-3-one (CMIT/MIT) against corrosiveVibrio harveyibiofilm was evaluated. The results revealed thatD-Tyr andD-Met alone can enhance the biocidal efficacy of CMIT/MIT, while the treatment of 5 ppm CMIT/MIT, 1 ppmD-Tyr and 100 ppmD-Met showed the best efficacy comparable to that of 25 ppm CMIT/MIT alone. The triple combination treatment successfully prevented the establishment of the corrosiveV. harveyibiofilm and effectively removed the matureV. harveyibiofilm. These conclusions were confirmed by the results of sessile cell counts, images obtained by scanning electron microscope and confocal laser scanning microscope, and the ATP test kit.
