The antioxidative activity of oral hypoglycemic agents

Abstract: Oral hypoglycemic agents, such as glibenclamide, gliclazide, metformin, rosiglitazone maleate, and diabenol, are known to exert in vitro a mild direct antioxidatove action. Rosiglitazone maleate showed moderate activity only on the hemiluminescence model with generation of active oxygen species while diabenol behaves as a scavenger of superoxide anion and hydroxyl radical in model hemiluminescence systems. Gliclazide exhibited dose-dependent activity only with respect to stable diphenyl-1-picrylhydrazyl (DPPG)… Show more

“…It was established that diabenol is a scavenger of superoxide anion, hydroxyl, and peroxyl radicals; rosiglitazone is active only against the superoxide anion, gliclazide has an antiradical effect in experiments with DPPH, and metformin and glibenclamide were unable to interfere with these processes. At the same time, the established direct antioxidant properties of some studied drugs are difficult to be expected in vivo, since they require relatively high concentrations to exert antiradical activity in vitro [47,48]. Table 1.…”

“…Об'єктом дослі-джень були білі безпородні щурисамці (125 тварин) з початковою масою 160-180 г. Тварин утримували в звичайних умовах віварію. Щури були адаптовані 10 діб у дослідній кімнаті й по-ділені на 7 груп: 1ша (контрольна) -здорові щури (К); 2-7 -тварини з експериментальним цукровим діабетом (ЕЦД): 2га -тварини з ЕЦД, виведені з експерименту на 21 добу (ЦД1); 3тя -тварини з ЕЦД, виведені з експерименту на 35 добу (ЦД2); 4та -тварини з ЕЦД+профілак- При виборі експериментальної моделі стреп-тозотоциніндукованого цукрового діабету спира-лися на рекомендації [15,16], які показали, що при попередньому введенні нікотинаміду підви-щується стійкість βклітин острівців Лангерганса до пошкоджувальної дії стрептозотоцину. Це дозволяє змоделювати стан, максимально близь кий до цукрового діабету 2 типу, який про-являється помірною і стабільною гіперглікемією, присутністю глюкози в сечі без явищ ацидозу.…”

“…The chemical class of substituted heterocyclic benzimidazoles is considered to be the base structure of new drugs based on it, which was shown by a wide range of biological activity shown before (Spasov et al 1997, Anisimova et al 2002, 2006, Spasov et al 2009, Kucheryavenko et al 2014, Kucheryavenko 2016). The previous studies determined the ability of benzimidazole derivatives containing spatially hindered phenol in their structure to inhibit oxidative stress.…”
