Toxic effects of diamino diphenyl sulphone
Samples of para and meta aminophenyl-Psulphatoethyl sulphone
were generously provided by BASF.
Further, its operations are supported by backward integration for key dye intermediates, mainly H-Acid and Vinyl Sulphone
A variety of polymers was considered for insulation systems including polysulphone, polyether sulphone
, polyurea, five-layer PP foam, polyamide thermal barrier and fivelayer PP, HT rubber, syntactic phenolic foam and syntactic epoxy with a PU outer insulation layer.
Success by others in identifying two sulphone
compounds (V147, V186) with potential therapeutic effect in experimentally infected animals heralded the need for clinical trials in humans.
Sulpha medications (SMZ and dapsone, a sulphone
) interfere with folate synthesis by competitively inhibiting the enzyme dihydropteroate synthase (DHPS) encoded by the folic acid synthase (FAS) gene, a multifunctional gene that also encodes dihydroneopterin aldolase and hydroxymethyldihydropterin pyrophosphokinase (5).
Pesticide (aldicarb sulphoxide, aldicarb sulphone
, demeton-S-methyl sulphoxide, carbendazim, methomyl, thiabendazole, methiocarb sulphoxide, methiocarb sulphone
, aldicarb, imazalil, thiodicarb, phorate sulphoxide, phorate sulphone
, methiocarb) standard substances were obtained from Dr.
The chloroform layer was evaporated and the product of this reaction was identified as diphenyl sulphone
Sikament-FF-N naphthalene formaldehyde sulphone
) was the superplasticizer used, and technical information given is as follows: pH 9, liquid, density 1.22 kg/l, proposed amount of cement weight 0.8-3.0% (Table 2).
TAA is bioactivated by CYP450 and/or flavin containing monooxygenase systems to toxic metabolites TAA sulfine (sulphoxide) and sulfene (sulphone
), which produce centrilobular hepatic necrosis and apoptosis (Dogru-Abbasoglu et al., 2001).
Each filtration module within the ultra-filtration plant is constructed from hydrophilic polyether sulphone
hollow fibres, this structure effectively guarantees high levels of physical and chemical stability.
Today, most people who suffer from Hansen s Disease are treated as outpatients with sulphone
drugs, which became available in 1947.
