Однако оставалось не ясным, связана ли эта активность с активацией VEGF-А, поскольку, с одной стороны, имеются сообщения о том, что NGF-опосредованный ангиогенез может быть инициирован и путём активации NGF фактора роста эндотелия сосудов VEGF-A, а с другой стороны, было показано, что селективный антагонист Flk1 рецепторов, специфичных для VEGF-A, соединение SU-5416 не влияет на ангиогенный эффект NGF. Цель исследования. Изучение влияния селективной блокады VEGF на антишемическую активность агониста TrkA рецепторов соединения ГК-2. Методы. Оценку антиишемической активности соединения ГК-2 проводили в модельных экспериментах, воспроизводящих ишемию задней конечности у крыс. Результаты. Показано, что на фоне блокады связывания VEGF-A со специфичными для него (VEGFR1 /Flt-1/ и VEGFR2 /KDR/) рецепторами препаратом бевацизумаб (2,5 мг/кг, в/б, каждые 3 дня на протяжение 14 дней) соединение ГК-2 (1 мг/кг, в/б, ежедневно, в течение 14 дней) реализует свою антиишемическую активность. Заключение. Результаты настоящих экспериментов свидетельствуют о том, что селективная блокада VEGF не оказывает существенного влияния на противоишемическую активность дипептидного миметика NGF – соединения ГК-2, обладающего свойствами агониста TrkA рецепторов.  </p></abstract><trans-abstract xml:lang="en"><p>Earlier, in experiments in vitro and in vivo, it was shown that the TrkA receptor agonist compound GK-2, which was a low molecular weight NGF mimetic, had pronounced angiogenic and antiischemic activity. However, it remained unclear whether this activity was associated with the activation of VEGF-A, since, on the one hand, there are reports that NGF-mediated angiogenesis can be initiated by activating NGF of the vascular endothelial growth factor VEGF-A, and on the other hand, it is shown that a selective antagonist of Flk1 receptors specific for VEGF-A, compound SU-5416 does not affect the angiogenic effect of NGF. Purpose of the investigation. Study of the selective VEGF blockade effect on the antiischemic activity of the TrkA receptor agonist GK-2. Methods. Evaluation of the compound GK-2 antiischemic activity was assessed in model experiments simulating hind limb ischemia in rats. Results. It has been shown that against the background of blockade of VEGF-A binding with specific for it (VEGFR1 / Flt-1 / and VEGFR2 / KDR /) receptors, bevacizumab (2.5 mg / kg, i.p., every 3 days for 14 days) compound GK-2 (1 mg / kg, i.p., daily, for 14 days) realizes its antiischemic activity. Conclusion. The results of these experiments indicate that the selective blockade of VEGF does not significantly affect the anti-ischemic activity of the dipeptide NGF mimetic compound GK-2, which has the properties of a TrkA receptor agonist.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>агонист TrkA-рецепторов – соединение ГК-2</kwd><kwd>антагонист TrkA-рецепторов – соединение ГК-1</kwd><kwd>бевацизумаб</kwd><kwd>ишемия задней конечности у крыс</kwd><kwd>антиишемическое действие</kwd></kwd-group><kwd-group xml:lang="en"><kwd>TrkA receptor agonist – GK-2 compound</kwd><kwd>TrkA receptor antagonist – GK-1 compound</kwd><kwd>bevacizumab</kwd><kwd>hind limb ischemia in rats</kwd><kwd>antiischemic effect</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">Donovan MJ, Miranda RC, Kraemer R et al.
