Synthesis of novel seco-acyclo-N-diazolyl-thione nucleosides analogous derived from acetic acid: characterization, complex formation with ions Pb(II), Hg(II) and antibacterial activity

Chehrouri, Manel,Othman, Adil A.

, p. 893 - 899 (2021/08/09)

Three diazoles namely 5-methyl-1,3,4-oxadiazole -2(3H)-thione, 5-methyl-1,3,4-thiadiazol-2(3H)-thione and 4-amino-5-methyl-2H-1,2,4-triazole-3-thiol were synthesized from acetic acid or ethyl acetate. Seco-acyclo-N-nucleoside analogous was synthesized by condensation of 1,3-benzylidine-glyceryl-2-tosylate with the three diazoles. Structural proof was based upon IR, 1H-NMR, 13C-NMR spectroscopy and MS measurements. The tendency to form complex between 1,3,4-oxadiazole and 1,3,4-thiadiazoles and Pb(II) and Hg(II) ions was achieved, and their structures were assigned by observing some changes in physical properties such as, MP, coloration, Rf (TLC), IR and UV spectroscopy. Most compounds were tested in vitro against Gram-positive and Gram-negative bacteria and showed variable activity. Hg2+ complexes of oxadiazole and thiadiazole derivatives exhibited appreciable antibacterial effect at lower MIC, compatible to the reference vancomycin. Similarly, oxadiazole-nucleoside exhibited high effect on Gram-positive bacteria. Graphic abstract: [Figure not available: see fulltext.]

, (2020/12/23)

Phenylthio heterocyclic compounds are widely used because of their diverse biological activities and medicinal prospects. Here, a facile method was reported. An arylation of 1,3,4-oxa(thia)diazol-2-thiones reacting with arynes to build C(aryl)-S bonds in the presence of CsF had good yields and excellent selectivity. The reaction was completed in short time without using expensive reagents and catalysts. Present reaction system is an efficient procedure to process phenylthio heterocyclic compounds and reveals a sustainable method and better application prospects in future organic synthesis.

Rational Optimization and Action Mechanism of Novel Imidazole (or Imidazolium)-Labeled 1,3,4-Oxadiazole Thioethers as Promising Antibacterial Agents against Plant Bacterial Diseases

Wang, Pei-Yi,Wang, Ming-Wei,Zeng, Dan,Xiang, Meng,Rao, Jia-Rui,Liu, Qing-Qing,Liu, Li-Wei,Wu, Zhi-Bing,Li, Zhong,Song, Bao-An,Yang, Song

, p. 3535 - 3545 (2019/03/26)

The emergence and widespread occurrence of plant bacterial diseases that cause global production constraints have become major challenges to agriculture worldwide. To promote the discovery and development of new bactericides, imidazole-labeled 1,3,4-oxadiazole thioethers were first fabricated by integrating the crucially bioactive scaffolds of the imidazole motif and 1,3,4-oxadiazole skeleton in a single molecular architecture. Subsequently, a superior antibacterial compound A6 was gradually discovered possessing excellent competence against plant pathogens Xanthomonas oryzae pv oryzae and Xanthomonas axonopodis pv citri with EC50 values of 0.734 and 1.79 μg/mL, respectively. These values were better than those of commercial agents bismerthiazol (92.6 μg/mL) and thiodiazole copper (77.0 μg/mL). Further modifying the imidazole moiety into the imidazolium scaffold led to the discovery of an array of potent antibacterial compounds providing the corresponding minimum EC50 values of 0.295 and 0.607 μg/mL against the two strains. Moreover, a plausible action mechanism for attacking pathogens was proposed based on the concentration dependence of scanning electron microscopy, transmission electron microscopy, and fluorescence microscopy images. Given the simple molecular structures, easy synthetic procedure, and highly efficient bioactivity, imidazole (or imidazolium)-labeled 1,3,4-oxadiazole thioethers can be further explored and developed as promising indicators for the development of commercial drugs.

Propylene oxide assisted one-pot, tandem synthesis of substituted-1,3,4- oxadiazole-2(3H)-ones in water

Yan, Xu,Zhou, Shuo,Wang, Yuanqiang,Ge, Zemei,Cheng, Tieming,Li, Runtao

experimental part, p. 7978 - 7983 (2012/09/21)

It has been developed for the synthesis of substituted-1,3,4-oxadiazole- 2(3H)-one derivatives via a novel one-pot, tandem procedure assisted by propylene oxide. The 5-substitued-1,3,4-oxadiazole-2(3H)-ones and 3,5-disubstitued-1,3,4-oxadiazole-2(3H)-ones were, respectively, obtained from three-component reaction of acylhydrazines, carbon disulfide, and propylene oxide, and four-component reaction of acylhydarazines, carbon disulfide, propylene oxide, and organic halides. The reactions were carried out using water as solvent in the presence of potassium phosphate to afford the expected products in good to excellent yields.

Synthesis of GABAA receptor agonists and evaluation of their α-subunit selectivity and orientation in the GABA binding site

Jansen, Michaela,Rabe, Holger,Strehle, Axelle,Dieler, Sandra,Debus, Fabian,Dannhardt, Gerd,Akabas, Myles H.,Lüddens, Hartmut

supporting information; experimental part, p. 4430 - 4448 (2009/06/06)

Drugs used to treat various disorders target GABAA receptors. To develop α subunit selective compounds, we synthesized 5-(4-piperidyl)-3-isoxazolol (4-PIOL) derivatives. The 3-isoxazolol moiety was substituted by 1,3,5-oxadiazol-2-one, 1,3,5-oxadiazol-2-thione, and substituted 1,2,4-triazol-3-ol heterocycles with modifications to the basic piperidine substituent as well as substituents without basic nitrogen. Compounds were screened by [3H]muscimol binding and in patch-clamp experiments with heterologously expressed GABAA αiβ 3γ2 receptors (i = 1-6). The effects of 5-aminomethyl-3H-[1,3,4]oxadiazol-2-one 5d were comparable to GABA for all α subunit isoforms. 5-piperidin-4-yl-3H-[1,3,4]oxadiazol-2-one 5a and 5-piperidin-4-yl-3H-[1,3,4]oxadiazol-2-thione 6a were weak agonists at α2-, α3-, and α5-containing receptors. When coapplied with GABA, they were antagonistic in α2-, α4-, and α6-containing receptors and potentiated α3-containing receptors. 6a protected GABA binding site cysteine-substitution mutants α1F64C and α1S68C from reacting with methanethiosulfonate-ethylsulfonate. 6a specifically covalently modified the α1R66C thiol, in the GABA binding site, through its oxadiazolethione sulfur. These results demonstrate the feasibility of synthesizing α subtype selective GABA mimetic drugs.

studies on anti-helicobacter pylori agents. Part 2: New cephem derivatives

Yoshida, Yoshiki,Matsuda, Keiji,Sasaki, Hiroshi,Matsumoto, Yoshimi,Matsumoto, Satoru,Tawara, Shuichi,Takasugi, Hisashi

, p. 2317 - 2335 (2007/10/03)

The synthesis and optimization of the anti-Helicobacter pylori activity of a novel series of cephem derivatives are described. Introduction of thio-heterocyclic groups containing N- and S-atoms to the 3-position and phenyl or thienyl acetamido groups to the 7-position of the cephem nucleus dramatically improved the activity. From this series of derivatives, compound 13i was found to have extremely potent in vitro anti-H. pylori activity, superior therapeutic efficacy compared to AMPC and CAM, no cross-resistance between CAM or MNZ and low potential for causing diarrhea due to instability to β-lactamase.
