Sažetak

Herein we present the synthesis of versatile amidino substituted benzothiazole 3–10 and benzimidazole 12–19 derivatives substituted with the variable number of hydroxy and methoxy groups. Furthermore, the synthesized compounds were explored for their antioxidative activity in vitro by using three biological assays, namely DPPH, ABTS and FRAP. The obtained results indicated that the variable number of hydroxy groups together with the type of the amidino substituent strongly influenced the antioxidative activity and reducing power of tested compounds. The most promising antioxidative activity showed trihydroxy substituted compounds 6, 10, 15 and 19. In general, it was noticed that unsubstituted amidino group induced the more pronounced activity in comparison to derivatives bearing 2-imidazolinyl group.
