Abstract
Three 1,2 dithiole 3-thion fluoroquinolone esters (2-4) were prepared via condensation of (p-hydroxyl phenyl) -1,2dithiole- 3-thione with fluoroquinolones (Ciprofloxacin, Gatefloxacin and Moxifloxacin). The biological activity of these compounds was assayed against 60 types of cancer cells in vitro. The compound 2 (NSC=760553) showed anticancer activity against renal cell, while the comound 4 (NSC=760555) show activity against three types of cancer cell. The expected mechanism of their activity is that 1,2dithiole 3-thione derivatives may give H2S as new gas transmitter which play an important role in the biological systems.
