Hydroxy isothiocyanates (ITCs), including some new derivatives of naturally occurring compounds, were synthesized and their minimum inhibitory, minimum fungicidal, and minimum bactericidal concentrations for Aspergillus niger, Aspergillus fumigatus, Staphylococcus aureus, and Escherichia coli were estimated. These compounds were strongly antimicrobial; for example, 2-(4-hydroxyphenyl) ethyl ITC...

Benzophenone and bisphenol A are environmental pollutions, which have been listed among "chemicals suspected of having endocrine disrupting effects" by the World Wildlife Fund, the National Institute of Environmental Health Sciences in the USA and the Japanese Environment Agency. The cultured cells of Nicotiana tabacum glycosylated benzophenone to three glycosides, 4-O-beta-D-glucopyranosylbenz...

The O2-independent hydroxylase 4-ethylphenol methylenehydroxylase (4EPMH) from Pseudomonas putida JD1 catalysed the complete conversion of 4-ethylphenol into 1-(4-hydroxyphenyl)ethanol together with a small amount of 4-hydroxyacetophenone, but with no formation of the side product 4-vinylphenol reported to be formed when the similar enzyme p-cresol methylhydroxylase (PCMH) catalyses this reacti...

Cationic surfactant, cetylpyridinium bromide (CPB), sensitizes the colour reaction of cerium(IV) with 1,3-o-hydroxyphenyl-5-phenylformazan(I), 1-m-hydroxyphenyl-3-o-hydroxyphenyl-5-phenylformazan(II) and 1-m-carboxyphenyl-3-o-hydroxyphenyl-5-phenylformazan(III). The formation of a soluble ternary complex of stoichiometric ratio 1:1:1 (Ce(IV)-R-CPB) is responsible for the observed enhancement in...

Crown-ether like interaction of two neutral [Cu2(μ-OH)(μ-L(1))] (H3L(1) = 2-(2'-hydroxyphenyl)-1,3-bis[4-(2-hydroxyphenyl)-3-azabut-3-enyl]-1,3-imidazolidine) fragments, around a central Na(+) cation as self-assembly template, led to the formation of [Na{Cu2(μ-OH)(μ-L(1))}2]ClO4 (1). Di-tert-butyl group substituted H3L(2) {2-(3,5-di-tert-butyl-2-hydroxyphenyl)-1,3-bis[4-(3,5-di-tert-butyl-2-hyd...

The kinetic reaction of the benzofuran–stilbene hybrid compound 5-(2-(2-(4-hydroxyphenyl)benzofuran-5-yl)vinyl)benzene-1,3-diol captures HOO? free radical.
