A series of novel methylthio-, sulfinyl-, and sulfonyl-8H-thieno[2,3-b] pyrrolizin-8-oximino derivatives 7A-12P was designed and synthesized as anti-tumor agents. Their structures were confirmed by IR, 1H-NMR, MS, and elemental analysis. The anti-tumor activities of all the target compounds were tested by the MTT method in vitro against Bel-7402 (human liver cancer) and HT-1080 (human fibro sarcoma) cell lines. Among them, compound UN (IC 50 = 18.2 μM, 8.2 μM), was the most promising compound of all synthesized molecules, it was 2.5- and 3.3-times more active than cisplatin (IC50 = 45.2 μM, 26.7 μM), respectively.
