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). The radical adopts a twisted dimer structure in the solid state which is similar to the structures observed for other alkyl derivatives.

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.

COMPARATIVE-STUDY OF AROMATICITY IN 5-MEMBERED RINGS CONTAINING S, SO AND SO2 GROUPS

Owing to the importance of the concept of aromaticity, different indices have been developed to try to quantify this property. The possible pi-delocalization through an X-SOn-X group (X = C, N; n = 0, 1 or 2) could explain heteroaromaticity in rings containing the moiety. For that reason, the aromaticity of five-membered sulphur-containing rings with different oxidation numbers (S, SO and SO2) and including no (thiophene), one (isothiazole) or two (1,2,5-thiadiazole) adjacent atoms was investigated. Ab initio calculations were carried out to determine geometrical parameters (planarity of the ring, bond length and bond order), electronic structure (charge distribution and dipolar moment) and the participation of d-orbitals of sulphur. According to these calculations, only compounds with S(II) can be considered to be aromatic, whereas compounds bearing S(IV) or S(VI) are better described as ylides.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 80-07-9, in my other articles.

Non-nucleoside inhibitors of HCV polymerase NS5B. Part 4: Structure-based design, synthesis, and biological evaluation of benzo[d]isothiazole-1,1-dioxides

A series of benzo[d]isothiazole-1,1-dioxides were designed and evaluated as inhibitors of HCV polymerase NS5B. Structure-based design led to the incorporation of a high affinity methyl sulfonamide group. Structure-activity relationship (SAR) studies of this series revealed analogues with submicromolar potencies in the HCV replicon assay and moderate pharmacokinetic properties. SAR studies combined with structure based drug design focused on the sulfonamide region led to a novel and potent cyclic analogue. (C) 2009 Elsevier Ltd. All rights reserved.

Antipoliovirus activity and mechanism of action of 3-methylthio-5-phenyl-4-isothiazolecarbonitrile

Our previous studies described the synthesis and the antiviral activity of 3,4,5-trisubstituted isothiazole derivatives that were found to be particularly effective against enteroviruses. Compound 3-methylthio-5-phenyl-4-isothiazolecarbonitrile (IS-2) exhibited an interesting anti-poliovirus activity with a high selectivity index. In the present study we investigated the mechanism of action of this compound. Studies on the time of IS-2 addition to poliovirus type 1 infected cells suggested that the compound may inhibit some early process of viral replication. In order to determine its mechanism of action, we evaluated the rate of attachment and internalization of purified [(3)H]uridine-labeled poliovirus to HEp-2 cells in the presence or absence of IS-2. No effect on poliovirus adsorption and internalization to host cells was detected. We also investigated the influence of the compound on virus uncoating using labeled poliovirus and measuring the radioactivity of oligoribonucleotides formed from viral RNA susceptible to ribonuclease. These experiments demonstrated that poliovirus uncoating is influenced by IS-2 action. (C) 2010 Elsevier B.V. All rights reserved.
