A new series of N-phenylpyrrolecarbothioamides were obtained from base catalyzed intramolecular cyclization of 3-amino-3-(alkyl or arylamino)propenethioamides. Pyrrole derivatives were evaluated for their in vitro anticancer activity toward cell lines of nine different types of human cancer. Some of newly prepared compounds demonstrated inhibitory effects on the growth of a wide range of cancer cell lines generally at 10(-6) M level and in some case at 10(-8) M concentrations.

Propenethioamides in the synthesis of heterocyclic systems. Synthesis of pyrrole and 1,4-thiazepine derivatives
The reaction of propenethioamides 1 with bromoketones 2 and 3 led in acidic medium to the formation of 1,4-thiazepines 6 and 7. The pyrrole derivatives 4 and 5 were obtained by reaction of 1 with 2 and 3 in basic medium.
