In order to understand the mechanism of oxidation of lactose, a systematic kinetic study of oxidation of lactose with photochemicaUy generated radicals was carried out. The reaction has a first order dependence on chloramine-T as well as on substrate. The reaction is catalysed by H+ ions as well. On the basis of kinetic results and product analysis a probable mechanism were suggested.展开更多
A new and novel class of bis(heterocycles) viz., bis pyrroles, pyrrolyl pyrazoles and pyrrolyl isoxazoles are prepared from 1-aroyl-2-styrylsulfonylethenes by 1,3-dipolar cycloaddition of tosylmethyl isocyanide, diazo...A new and novel class of bis(heterocycles) viz., bis pyrroles, pyrrolyl pyrazoles and pyrrolyl isoxazoles are prepared from 1-aroyl-2-styrylsulfonylethenes by 1,3-dipolar cycloaddition of tosylmethyl isocyanide, diazomethane, nitrile imines and nitrile oxides. The lead compounds are screened for antimicrobial activity.展开更多
In the present investigation, series of Bis (heterocycle)s bearing pyrazoline in combination of the imidazole derivatives have been synthesized via 1,3-dipolar cycloaddition reactions of N-(nitrobenzyl)-imidazole nitr...In the present investigation, series of Bis (heterocycle)s bearing pyrazoline in combination of the imidazole derivatives have been synthesized via 1,3-dipolar cycloaddition reactions of N-(nitrobenzyl)-imidazole nitrile imines with different dipolarophiles. All the newly synthesized compounds were characterized and screened for analgesic-anti-inflammatory activities and were compared with the standard drugs. The compounds exhibited excellent anti-inflammatory and analgesic activities. Out of the compounds studied 4b, 4d and 4g compounds shown statistically significant activity comparable to the standard drugs Ibuprofen and Aspirin at the same dose.展开更多
