The 2-[2-(2-phenylethenyl)cyclopent-3-en-1-yl]-1,3-benzothiazoles were synthesized from the reactions of 7-benzylidenebicyclo[3.2.0]hept-2-en-6-ones with 2-aminobenzenethiol. The antiproliferative activities of 2-[2-(2-phenylethenyl)cyclopent-3-en-1-yl]-1,3-benzothiazoles were determined against C6 (rat brain tumor) and HeLa (human cervical carcinoma cells) cell lines using BrdU cell proliferation ELISA assay. Cisplatin and 5-fluorouracil (5-FU) were used as standards. The most active compound was 2-{(1S,2S)-2-[(E)-2-(4-methylphenyl)ethenyl]cyclopent-3-en-1-yl}-1,3-benzothiazole against C6 cell lines with IC50=5.89 mu m value (cisplatin, IC50=14.46 mu m and 5-FU, IC50=76.74 mu m). Furthermore, the most active compound was 2-{(1S,2S)-2-[(E)-2-(2-methoxyphenyl)ethenyl]cyclopent-3-en-1-yl}-1,3-benzothiazole against HeLa cell lines with IC50=3.98 mu m (cisplatin, IC50=37.95 mu m and 5-FU, IC50=46.32 mu m).
