Green synthesis and biological evaluation of 6-substituted-2-(2-hydroxy/methoxy phenyl)benzothiazole derivatives as potential antioxidant, antibacterial and antitumor agents
hydroxy and methoxy groups on the 2-arylbenzothiazole scaffold, as well as the influence of the type of substituents placed on the C-6 position of benzothiazole moiety on biological activity, including antibacterial, antitumor and antioxidant activity. Modest activity was observed against the tested Gram-positive and Gram-negative bacterial strains for only amidino derivatives 5d and 6d. The tested compounds

benzothiazole imidazoline 11b, containing a phenoxymethylene linker, exhibited the best antitrypanosomal potency (IC90 = 0.12 µM). DNAbinding assays showed a non-covalent interaction of 6-amidinobenzothiazole ligands, indicating both minor groove binding and intercalation modes of DNA interaction. Our findings encourage further development of novel structurally related 6-amidino-2-arylbenzothiazoles to obtain
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
HuT78 cells with IC50 < 10 µM. Moreover, compounds 45c and 46c containing the methoxy group at the phenoxy unit were not toxic to normal BJ cells. Of all the tested compounds, benzimidazole 45a with the unsubstituted phenoxy central core showed the most pronounced cell growth inhibition on THP1 cells in the nanomolar range (IC50 = 0.8 µM; SI = 70).

Novel benzo[b]thienyl and 2-bithienyl amidino-substituted benzothiazoles and benzimidazoles were shown to have antitumor and antitrypanosomal activities in vitro. Benzothiazoles were found to be more active than benzimidazole analogs as both antiproliferative and antitrypanosomal agents. Benzothiazoles were selective against lung carcinoma cells, and the benzimidazoles were selective against cervical
