Spermicidal Activity of Oxovanadium: MATERIALS AND METHODS(1)

Oxovanadium(IV) Complexes Containing 1,10-Phenanthroline, 2,2′-Bipyridyl, or 5′-Bromo-2′-Hydroxyacetophenone and Derivatives The names of the 11 oxovanadium complexes synthesized and tested in this study are listed in Table 1. The chemical structures of 10 cationic complexes with either mono- or bis-1,10-phenanthroline and 2,2′-bipyridyl, and one neutral complex, bis-5′-bromo-2′-hydroxyacetophenone, are depicted in Figure 1. flovent inhaler

Since the redox potential and the stability of metal complexes are greatly affected by the ancillary groups, different ligands were selected to test their effects on spermicidal activity and stability. The stability of organometallic complexes with monodentate ligands in aqueous solutions was found to be improved by chelating effects of certain biden-tate ligands, particularly dithiocarbamate […]

Oxidative damage to sperm proteins, carbohydrates, and DNA is an important pathophysiological mechanism in the onset of male infertility. Superoxide radicals generated by the action of xanthine oxidase exert a direct, suppressive effect on sperm function, leading to loss of motility, impaired capacitation, and poor sperm-egg interaction. ventolin 100 mcg

Vanadium is a physiologically essential element found in both anionic and cationic forms, with oxidation states ranging from -1 to +5 (I-V). This versatility gives vanadium complexes unique properties. In particular, the cationic form of vanadium complexes with oxidation state +4 (IV) function as modulators of cellular redox potential, regulate enzymatic phosphorylation, and exert pleiotropic […]
