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 well serve as organic antiglucocorticoid (Muller et al., 2006), and it might be involved within 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 effective effect 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 seems to have positive aspects to improve symptoms of depression, anxiousness and pressure problems (Sageman et al., 2012). As opposed to DHEA, 7-keto-DHEA has no androgenic activity and it can not be converted to androgens and oestrogens recognized to enhance the risk of hormonedependent illnesses. For this reason and due to a causal hyperlink involving declining DHEA Plasmodium Inhibitor list levels and agerelated loss of cognitive function, 7-oxo-DHEA was suggested as a safe alternative to DHEA supplementation. In some nations, it truly is commercially available and employed also as nutritional supplement in sport (Kazihnitkova et al., 2007). As reported in the accessible scientific literature, 7-oxoDHEA (1) metabolism in humans is primarily concerned with all the reduction of C-17 ketone by 17b-hydroxysteroid dehydrogenase (17b-HSD) producing 3b,17b-dihydroxyandrost-5-en-7-one (2) or/and reduction of the ketone at C-7 position by 11b-HSD1 leading for the formation of epimeric 7b- (mainly) 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 (four) and 3b,7b,17b-trihydroxy-androst-5-ene (five)) (Nashev et al., 2007). These metabolites are multifunctional compounds implicated inside a broad array of biological processes, primarily attributed to immune technique modulation, anti-inflammatory, antiglucocorticoid and neuroprotective actions (El Kihel, 2012; Starka, 2017; Starka et al., 2018). Alterations in the ratio of 7a/7b-hydroxy-DHEA and each isomeric triols had been detected in sufferers with a variety of disorders including vascular and Alzheimer dementia (Starka, 2017). The derivatives of 7-oxo- or 7-hydroxyDHEA with an more 16a-hydroxy group were isolated from urine of the patient with adrenal carcinoma2021 The Authors.
