Synthesis and biological activity of benzothiazolo- and benzoxazolo[3,2-a]quinolinium salts

Article abstract of DOI:10.1021/jm00353a020

The hitherto unknown 3-nitrobenzothiazolo- and 3-nitrobenzoxazolo[3,2-a]quinolinium salts were synthesized via the photochemically induced cyclization of the corresponding 2-(2-chloro-5-nitrostyryl)benzothiazole and 2-(2-chloro-5-nitrostyryl)benzoxazole. Results on their cytotoxic and antitumor activity are presented.
