Synthesis and antitumor activity of 2,5-bis(3′-indolyl)-furans and 3,5-bis(3′-indolyl)-isoxazoles, nortopsentin analogues
摘要:
A series of novel 2,5-bis(3'-indolyl)furans and 3,5-bis(3'-indolyl) isoxazoles were synthesized as antitumor agents. The antiproliferative activity was evaluated in vitro toward diverse human tumor cell lines. Initially 5 isoxazoles and 3 furan derivatives were tested against a panel of 10 human tumor cell lines and the most active derivatives 3c and 4a were selected to be evaluated in an extended panel of 29 cell lines. By exhibiting mean IC(50) values of 17.4 mu g/mL (3a) and 20.5 mu g/mL (4c), in particular 4c showed a high level of tumor selectivity toward the 29 cell lines. (C) 2010 Elsevier Ltd.

Synthesis and antitumor properties of 2,5-bis(3′-indolyl)thiophenes: Analogues of marine alkaloid nortopsentin
摘要:
A series of 11 bis-indolylthiophenes of type 8-10 were obtained by cyclization of diketones 4 and 7 using Lawesson's reagent. Derivatives 8c, 9c, 9d, and 10c were selected to be evaluated in the full panel of about 60 human tumor cell lines derived from nine human cancer cell types and showed antiproliferative activity generally in the micromolar range. The most sensitive cell lines were: CCRF-CEM, MOLT-4, HL60 (TB), and RPMI-8226 of the leukemia subpanel, HT29 and HCC-2998 cell lines of the colon sub-panel, NCI-H522 of the non-small cell lung cancer sub-panel, LOX IMVI of the melanoma sub-panel, and UO-31 of the renal cancer sub-panel.

Marine alkaloids were divided into five categories from the perspective of anti-tumor activity. The optimization process, chemical synthesis, anti-tumor activity evaluation and structure–activity relationship of various compounds were discussed.
2,5-bis(3'-Indolyl)pyrroles, analogues of the marinealkaloid nortopsentin, were conveniently prepared through a three step procedure in good overall yields. Derivatives 1a and 1b exhibited concentration-dependent antitumor activity towards a panel of 42 human tumor cell lines with mean IC50 values of 1.54 μM and 0.67 μM, respectively.
