substituted aralkyl) heterocyclic compounds

Abstract: A (substituted-aralkyl)heterocyclic compound of the formula I ##STR1## wherein R 1 is an azido, carbamoyl, cyano, formyl, hydroxy or nitro radical, a 1-6C 1-hydroxyalkyl, alkoxy, alkylcarbamoyl, alkylthio, alkylsulphinyl or alkylsulphonyl radical, a 2-cyanoethyl radical, optionally bearing one to four 1-6C alkyl substituents, or a 2-6C alkanoyl, halogenoalkanoyl, alkanoyloxy, alkanoylamino, dialkylcarbamoyl or alkoxycarbonyl radical; R 2 and R 3 , which may be the same or different, are each a hydrogen atom, a 1-6C alkyl, dueterioalkyl or halogenoalkyl radical, or a phenyl or phenyl(1-6C alkyl) radical, in each of which the phenyl may optionally bear one or more substituents; or R 2 and R 3 , together with the carbon atom to which they are attached, may form a 3- to 6-membered ring; or R 1 R 2 R 3 C- is a 1,1-dicyanoethyl or trifluoromethylsulphonyl radical; R 4 is a hydrogen or halogen atom, a cyano or nitro radical or a 1-6C alkyl or halogenoalkyl radical; R 5 has any of the values defined above for the group R 1 R 2 R 3 C but is not necessarily the same as R 1 R 2 R 3 C, or has any of the values defined above for R 4 but is not necesarily the same as R 4 , or is a carbamoyl, 1-pyrrolidinyl-carbonyl, piperidinocarbonyl, morpholinocarbonyl or nitro radical, a 1-6C alkoxy or halogenoalkoxy radical or a 2-6C alkanoyl or alkoxy-carbonyl radical; A is a methylene or ethylene radical optionally bearing one or more substituents selected from deuterium and halogen atoms, carbamoyl, cyano and hydroxy radicals, 1-6C alkyl and alkoxy radicals, and 2-6C alkanoyloxy radicals provided that when A is linked to R 6 through a nitrogen atom thereof, it may not bear a hydroxy, alkoxy or alkanoyloxy substituent on the carbon atom adjacent to such nitrogen atoms; and R 6 is a 1H-1,2,4-triazol-1-yl, 4H-1,2,4-triazol-4-yl, 1H-imidazol-1-yl, 5-cyano-1H-imidazol-1-yl, 3-pyridyl or 5-pyrimidinyl radical, or a 1H-imidazol-1-yl radical, bearing at the 5-position thereof a 1-6C alkyl substituent which is itself optionally substituted by one or more carbamoyl, cyano, hydroxy or 2-6C alkoxycarbonyl radicals; and provided that when R 2 , R 3 , R 4 and R 5 are hydrogen, A is a methylene radical and R 6 is a 3-pyridyl radical, R 1 is not a cyano, hydroxy or hydroxymethyl radical, and when R 1 is a hydroxy radical, R 3 , R 4 and R 5 are hydrogen, A is a methylene radical and R 6 is 3-pyridyl, R 2 is not a methyl or a 2-chloro-1-methylethyl radical, and provided that when R 1 is a methoxycarbonyl radical, R 2 , R 3 , R 4 and R 5 are hydrogen and A is a methylene radical, R 1 is not a 1H-imidazol-1-yl radical; and the pharmaceutically acceptable acid addition salts thereof.

Surface-modifying coating compositions

Abstract: Coating compositions suitable for application to optical surfaces to reduce surface misting and light reflection without creating haze comprise: (a) an inorganic particulate component selected from colloidal silica particles, colloidal alumina particles, or a mixture thereof wherein the silica or alumina particles have a small particle size represented by an average particle size in the range 7 to 50 nm and the particles comprise 05 to 25% weight/volume of the total composition; (b) another inorganic particulate component also selected from colloidal silica particles, colloidal alumina particles, or a mixture thereof wherein the silica and alumina particles have a large particle size represented by an average particle size in the range 75 to 150 nm and the particles comprise 02 to 10% weight/volume of the total composition; (c) 01 to 10% weight/volume of a polymeric binder; and (d) a volatile liquid medium The coating compositions provide especially beneficial properties when applied to thermoplastic films and sheets, -such as polyethylene terephthalate films Such films are suitable as coverings or claddings for horticultural growing houses, cold frames and cloches

The mode of action of l,2‐benzisothiazolin‐3‐one on Staphylococcus aureus

Abstract: 1,2-benzisothiazolin-3-one (BIT), at growth inhibitory concentrations, has little effect on membrane integrity but significantly inhibits the active transport and oxidation of glucose by washed Staphylococcus aureus cells. The dependancy of these metabolic processes on thiol-containing enzymes and the observed interaction of BIT with glutathione and isolated enzyme preparations suggests that cellular thiol groups are a major target for BIT.
