Подобно глюкозе сульфаниламиды вызывают изменения электрической активности в бета-клетках островков поджелудочной железы, конвенгируя главным образом на уровне АТФ-зависимых К+-каналов, не исключается их действие и на различные другие типы Са2+- чувствительных каналов.</p><p>Вместе с тем в последнее время на мембране бета-клеток обнаружены и идентифицированы высокоспецифические рецепторы для сульфаниламидных препаратов. Большие возможности сульфаниламидных препаратов второй генерации связываются с их возможностью запускать выделение инсулина в наномолярных концентрациях за счет высокой степени их сродства и прочного лигандно-рецепторного взаимодействия с рецепторными образованиями.</p><p>Имеющиеся в литературе данные по оценке связывающих способностей сульфаниламидных препаратов с бета-клетками весьма ограничены. В связи с этим нами была проведена работа по анализу рецепторного связывания глибенкламида, гликлазида и глипизида с бета-клетками.</p></abstract><trans-abstract xml:lang="en"><p>Analysis of pancreatic beta-cell receptors binding the sulfanilamide drugs widely used in therapy of type II diabetes, such as glybenclamide, glypizide, and glyclazide, showed that these drugs are characterized by excellent parameters of specific binding to these receptors. The receptors were tested for two parameters: number of binding sites and dissociation constant. Glybenclamide was the most active of the drugs we tested, the other two agents being less active. Binding of these agents was reversible. The problem of identification of the examined receptors of sulfanilamides with K+-ATP-sensitive channels, similarly active conductors of the information transported by the sulfanilamide drugs in the mechanism of insulin secretion, is discussed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Поджелудочная железа</kwd><kwd>Производные сульфонилмочевины</kwd><kwd>Рецепторы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Pancreas</kwd><kwd>Sulfonylurea derivatives</kwd><kwd>Receptors</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Бабичев В.Н., Игнатьев Н.С., Балаболкин М.И. // Пробл. эндокринол. — 1993. —№ 5. — С. 43—46.</mixed-citation><mixed-citation xml:lang="en">Бабичев В.Н., Игнатьев Н.С., Балаболкин М.И. // Пробл. эндокринол. — 1993. —№ 5. — С. 43—46.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Boyd А.
