Antimicrobial activity and structural study of disubstituted Thiourea Derivatives
(2007)
The antimicrobial activity of six N-phenyl- and fourteen N-benzoylthiourea derivatives were evaluated from their Minimal Inhibitory Concentration (MIC) values using the microdilution procedure against ten microorganisms. ...
Synthesis, structural and spectroscopic studies of 1-(2-FUROYL)-3- phenylthiourea: a theoretical and experimental approach
(Taylor & Francis Ltd, 2016-09-03)
The thiourea derivative 1-(2-Furoyl)-3-phenylthiourea (FPT) was synthesized and characterized by using spectroscopic (IR, Raman, UV–VIS, 1H and 13C NMR) and structural methods (powder X-ray diffraction data). The experimental ...
Effect of fluorine substitution on the crystal structures and vibrational properties of phenylthiourea isomers
(Elsevier Science, 2010-10)
The 1-(2-chlorobenzoyl)-3-(isomeric fluorophenyl)thiourea derivatives (1–3) were prepared by the reaction of 2-chlorobenzoyl isothiocyanate produced in situ with isomeric fluoroanilines in excellent yields. The novel ...
The first bismuth(III)-catalyzed guanylation of thioureas
(Tetrahedron Letters, 2006)
This work describes the first catalytic bismuth-promoted synthesis of polysubstituted guanidines in good yields through the guanylation reaction of N-benzoyl or N-phenylthioureas with primary and secondary amines, but now ...

First evidence of a potential antibacterial activity involving a laccase-type enzyme of the phenoloxidase system in Pacific oyster Crassostrea gigas haemocytes
Phenoloxidases (POs) are a group of copper proteins including tyrosinase, catecholase and laccase. In
several insects and crustaceans, antibacterial substances are produced through the PO cascade, participating in the ...
Orthopalladated acetophenone oxime compounds bearing thioamides as ligands: Synthesis, structure and cytotoxic evaluation
(2019-02-24)
Cleavage reactions involving the halide-bridged [Pd(μ-Cl)(C2,N-aphox)]2 precursor (aphox = acetophenone oxime) with thioamides, in the 1:2 molar ratio, yielded mononuclear cyclopalladated of the type [Pd(C2,N-aphox)(Cl)(L) ...
Synthesis, Characterization and Cytotoxicity Evaluation of New Biimidazole Palladium(II) Complexes with Thioureas
(Slovensko Kemijsko Drustvo, 2018-01-01)
The reactions between [PdCl2(tmbiimH(2))]center dot H2O (1) {tmbiimH(2) = 2,2'-bis(4,5-dimethylimidazole)} and thiourea (tu), N-methylthiourea (mtu), N-phenylthiourea (ptu), N,N'-dimethylthiourea (dmtu) or N,N'-diphenylthiourea ...
