NEUTRALIZATION OF ANGIOPOIETIN-2 AND VASCULAR ENDOTHELIAL GROWTH FACTOR (VEGF) FOR THERAPEUTIC PURPOSES

New blood vessels in organs and tissues are formed by angiogenesis, which can take place both in the normal condition and in tumour growth. Angiogenesis supports the strength and integrity of the connections in blood vessel endothelial cells with each other and with the basement membrane. This ensures nutrition of tissues and organs, saturation with oxygen, macronutrients and micronutrients. Along with this, angiogenesis contributes to timely elimination of metabolic products. Metastatic spreading and tumor growth are supported by uncontrolled angiogenesis, that is why it is important to study the works dedicated to neutralization of angiogenesis factors, which becomes a method of combating various oncological diseases and other pathologies. The aim of this work was to study the information about modern drugs, including those at the stage of clinical trials, capable of neutralizing angiopoietin-2 – an inhibitor of angiogenesis and vascular growth factor (VEGF) – an angiogenesis activator, to evaluate the effectiveness and safety of various doses of drugs in various pathologies, to analyze the current state of studying tumor angiogenesis, achievements and prospects for the use of antiangiogenic drugs in oncological practice. The main focus was on the role of angiogenesis inhibitors and activators. To construct and structure the meta-analysis, we conducted a systematic review of the literature, searching works in open Internet resources such as PubMed, CyberLeninka, PsycINFO, Elibrary, published in the period from January 1, 2016 to March 31, 2021, devoted to studies on the effectiveness of drugs aimed at neutralizing angiopoietin-2 and VEGF. Conference materials and dissertations were analyzed to obtain additional data on research in this area.
