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.

Design, Synthesis and Biological Evaluation of Isothiazole Based 1,2,4-Trizaole Derivatives

A series of novel 3,4-dichloroisothiazole based 1,2,4-triazole derivatives were rationally designed and synthesized. Their structures were confirmed by H-1 NMR, C-13 NMR, HRMS or elemental analysis; the typical crystal structure was determined by X-ray diffraction for validation. All target compounds were evaluated for their in vitro fungicidal and in vivo anti-TMV activities. The bioassay results indicated that compound 6b, namely 1-(3,4-dichloroisothiazol-5-yl)-1-(4-fluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanol, exhibited excellent growth inhibition against B. cinerea, C. arachidicola and P. piricola with median effective concentrations (EC50) of 6.98, 2.73 and 3.07 g/mL, respectively, and good in vivo anti-TMV activity of over 60% of inactivation and induction activity at 100 g/mL. These data demonstrate that compound 6b is both a fungicide and an anti-TMV lead, deserving further studies.

Synthesis of Fluorine-Containing Derivatives of 5-Arylisoxazoles and 4,5-Dichlorothiazole

Alkylation of fluorophenols and phenolic aldehydes with 5-phenyl(p-tolyl)-3-chloromethylisoxazole under the Williamson reaction conditions afforded the corresponding ethers. Condensation of the resulting phenolic aldehyde derivatives and 5-phenyl(p-tolyl)isoxazole-3-carbaldehydes with p-fluoroaniline resulted in fluorine-containing azomethines. Acylation of fluorinated amines with 5-(p-tolyl)isoxazole- and 4,5- dichloroisothiazole-3-carbonyl chlorides gave rise to fluorinated amides bearing isoxazole and isothiazole fragments, representatives of which showed a synergistic effect in compositions with insecticides.

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.

Novel derivatives of 1,3,4-oxadiazoles are potent mitostatic agents featuring strong microtubule depolymerizing activity in the sea urchin embryo and cell culture assays

A series of novel 1,3,4-oxadiazole derivatives based on structural and electronic overlap with combretastatins have been designed and synthesized. Initially, we tested all new compounds in vivo using the phenotypic sea urchin embryo assay to yield a number of agents with anti-proliferative, anti-mitotic, and microtubule destabilizing activities. The experimental data led to identification of 1,3,4-oxadiazole derivatives with isothiazole (5-8) and phenyl (9-12) pharmacophores featuring activity profiles comparable to that of combretastatins, podophyllotoxin and nocodazole. Cytotoxic effects of the two lead molecules, namely 6 and 12, were further confirmed and evaluated by conventional assays with the A549 human cancer cell line including cell proliferation, cell cycle arrest at the G2/M phase, cellular microtubule distribution, and finally in vitro microtubule assembly with purified tubulin. The modeling results using 3D similarity (ROCS) and docking (FRED) correlated well with the observed activity of the molecules. Docking data suggested that the most potent molecules are likely to target the colchicine binding site. (C) 2010 Elsevier Masson SAS. All rights reserved.
