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.

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.

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.

Experimental and theoretical investigation of new furan and thiophene derivatives containing oxazole, isoxazole, or isothiazole subunits

Herein, we present joint experimental and theoretical studies on newly designed thiophene- or furan-based oxazole, isoxazole, and isothiazole derivatives. Our synthetic approach towards the preparation of target compounds is based on Van Leusen reaction. By following this reaction, oxazoles (1 and 2) containing the pertinent heterocyclic systems were obtained from the reaction of suitable furan or thiophene derivatives with tosylmethyl isocyanide (TOSMIC). Hereby, three ring systems of furan or thiophene, linked to the oxazole rings at their 2- and 5-positions (3 and 4), were also successfully synthesized for the first time. Reaction of the starting materials containing acetyl groups in their 2-position with dimethyl acetal and following the treatment by hydroxylamine hydrochloride, desired isoxazole derivatives (5 and 6), were obtained. Additionally, isothiazole derivatives (7 and 8) were prepared by following the similar approach to the isoxazole synthesis. Whole of these cyclization reactions occurred with good to excellent yields. Structural analyses of the synthesized compounds were performed by appropriate spectroscopic methods (UV-vis, FT-IR, LC-MS, H-1-NMR, C-13-NMR, and elemental analysis). We also carried out theoretical studies for identifying the structure-activity relationship and determining chemical properties of the studied molecules. For this purpose, we obtained information about structural properties (bond lengths, bond angles, dihedral angles, and dipole moments), band gap energies, and spectroscopic characteristics (UV-vis, FT-IR, H-1-NMR, and C-13-NMR) of the target compounds.

Pyrazolo[3,4-c]isothiazole and isothiazolo[4,3-d]isoxazole derivatives as antifungal agents

Context: The diseases of plants and humans due to pathogenic fungi are increasing. Among the substances used to combat fungi, the azoles are of primary interest, both in agricultural field both in health. To avoid fungal resistance phenomena, the synthesis and tests of new derivatives are necessary. Objective: This article discusses the synthesis and the antifungal activity of pyrazolo[3,4-c]isothiazole and isothiazolo[4,3-d]isoxazole derivatives against three fungi that are pathogenic only for plants and two fungi that are opportunistic in humans and plants. Materials and Methods: The compounds were prepared starting from 2-cyano-3-ethoxy-2-butenethioamide. The antifungal activity of the compounds was determined by measuring the inhibition of growth of the fungi tested at 20, 50, and 100 mu A mu g/mL in comparison with the controls. Results: Results demonstrated that several compounds were able to control the mycelial growth of the tested fungi, even if they showed different sensitivity to the different azole-derivatives. In general Magnaporthe grisea (T.T. Hebert) Yaegashi & Udagawa was the most sensitive fungus, being blocked almost entirely by 4-chloro derivative even at 20 mu A mu g/mL, a concentration at which the reference commercial compound tricyclazole was nearly ineffective. Discussion and conclusion: These findings demonstrate that the pyrazolo[3,4-c]isothiazole derivatives have a wide spectrum of activity on phytopathogenic and opportunistic fungi. In particular the 4-chloro derivative seems to have a great potential as new product to combat M. grisea in the agricultural field.

Acyl Guanidine Inhibitors of beta-Secretase (BACE-1): Optimization of a Micromolar Hit to a Nanomolar Lead via Iterative Solid- and Solution-Phase Library Synthesis

This report describes the discovery and optimizition of a BACE-1 inhibitor series containing an unusual acyl guanidine chemotype that was originally synthesized as part of a 6041-membered solid-phase library. The synthesis of multiple follow-up solid- and solution-phase libraries facilitated the optimization of the original micromolar hit into a single-digit nanomolar BACE-1 inhibitor in both radioligand binding and cell-based functional assay formats. The X-ray structure of representative inhibitors bound to BACE-1 revealed a number of key ligand:protein interactions, including a hydrogen bond between the side chain amide of flap residue Gln73 and the acyl guanidine carbonyl group, and a cation-pi interaction between Arg235 and the isothiazole 4-methoxyphenyl substituent. Following subcutaneous administration in rats, an acyl guanidine inhibitor with single-digit nanomolar activity in cells afforded good plasma exposures and a dose-dependent reduction in plasma A beta levels, but poor brain exposure was observed (likely due to Pgp-mediated efflux), and significant reductions in brain A beta levels were not obtained.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 66-98-8 is helpful to your research. Formula: C14H10O2.
