  Synthesis and biological evaluation of cyclopenta[ c ]thiophene related compounds as new antitumor agents

  摘要：

  A series of 22 cyclopenta[c]thiophene related compounds was obtained by the pharmacomodulation of 6-amino-5,6- dihydro-4H-cyclopenta[c]thiophen-4-ones 1a-g. All compounds were evaluated for potential anticancer activity in the NCI's in vitro human disease-oriented tumor cell line screening panel that consisted of 60 human tumor cell lines arranged in nine subpanels, representing diverse histologies. Among these tested compounds. seven were found to be cytotoxic, especially against leukemia cell lines, allowing us to point out some structure activity relationships. These derivatives were further evaluated for potential in vivo anticancer activity in the hollow fiber assay developed at the NCI, which selected two compounds. If and 3a for standard xenograft testing. (C) 2002 Elsevier Science Ltd. All rights reserved.
