Than DHEA (El Kihel, 2012). It was even encouraged as a drug preventing Raynaud’s syndrome attacks (Kazih nitkova et al., 2007). 7-Oxo-DHEA may perhaps serve as natural antiglucocorticoid (Muller et al., 2006), and it might be involved in the development of an effective immune response (Arsenou et al., 2003; Vecchione et al., 2020). It has been suggested that 7-oxo-DHEA as an antagonist of c-aminobutyric acid subtype A receptor (GABAA) exerts a helpful impact for memory retention in mice. Its antagonizing activity towards GABAA partially eliminated the cholinergic dysfunction in induced amnesia in young mice (Shi et al., 2000). This compound also appears to possess positive aspects to enhance symptoms of depression, anxiousness and stress problems (Sageman et al., 2012). As opposed to DHEA, 7-keto-DHEA has no androgenic activity and it can’t be converted to androgens and oestrogens identified to enhance the risk of hormonedependent illnesses. Because of this and because of a causal hyperlink involving declining DHEA levels and agerelated loss of cognitive function, 7-oxo-DHEA was recommended as a protected alternative to DHEA supplementation. In some nations, it truly is commercially offered and utilised also as nutritional supplement in sport (Kazihnitkova et al., 2007). As reported in the accessible scientific literature, 7-oxoDHEA (1) metabolism in humans is mainly concerned together with the reduction of C-17 ketone by 17b-hydroxysteroid dehydrogenase (17b-HSD) generating 3b,17b-dihydroxyandrost-5-en-7-one (2) or/and reduction in the ketone at C-7 position by 11b-HSD1 top towards the formation of epimeric 7b- (primarily) and 7a- alcohols (7a- and 7bhydroxy-DHEA (three)), and their reduction to 3b,7a,17band 3b,7b,17b-triols (3b,7a,17b-trihydroxy-androst-5-ene (4) and 3b,7b,17b-trihydroxy-androst-5-ene (5)) (Nashev et al., 2007). These metabolites are multifunctional compounds implicated within a broad selection of biological processes, primarily attributed to immune technique modulation, anti-inflammatory, antiglucocorticoid and neuroprotective actions (El Kihel, 2012; Starka, 2017; Starka et al., 2018). Modifications within the ratio of 7a/7b-hydroxy-DHEA and each isomeric triols have been detected in individuals with a variety of disorders including vascular and Alzheimer dementia (Starka, 2017). The derivatives of 7-oxo- or 7-hydroxyDHEA with an added 16a-hydroxy group have been isolated from urine of the patient with adrenal carcinoma2021 The Authors.
