  Antitumor Agents. 254. Synthesis and Biological Evaluation of Novel Neo-tanshinlactone Analogues as Potent Anti-Breast Cancer Agents

  摘要：

  In our previous study, neo-tanshinlactone ( 1) showed potent and selective anti-breast cancer activity. To explore the SAR of 1, nine analogues (15-18, 24-28) were designed and synthesized. Together with 1 and tamoxifen (TAM), all newly synthesized compounds and some intermediates were evaluated for in vitro anticancer activity against several human tumor cell lines. Compounds without a ring D did not show promising activity, while compounds with a methylated furan ring D showed better activity than those with unsubstituted furan or hydroxy-dihydrofuran rings. Among all newly synthesized compounds, compound 15 with an ethyl group at the 4-position showed the best activity and selectivity with ED50 values of 0.45 and 0.18 mu g/mL against MCF-7 and ZR-75-1 (ER+) and 13.5 and 10.0 mu g/mL against MDA MB-231 and HS 587-1 (ER-), respectively. Furthermore, 15 also showed potent activity against SK-BR-3 (ER-, HER2+) with an ED50 value of 0.10 mu g/mL. Our preliminary SAR studies showed that a methylated furan ring D and the C-4 substituent in ring A are critical for anti-breast cancer activity. Further development of 1 and 15 as anti-breast cancer drug candidates is warranted.

  Antitumor Agents. 272. Structure−Activity Relationships and In Vivo Selective Anti-Breast Cancer Activity of Novel Neo-tanshinlactone Analogues

  摘要：

  Neo-tanshinlactone (1) and its previously reported analogues, such as 2, are potent and selective in vitro antibreast cancer agents. The synthetic pathway to 2 was optimized from seven to five steps, with a better overall yield. Structure-activity relationships studies on these compounds revealed some key molecular determinants for this family of antibreast agents. Several derivatives (19-21 and 24) exerted potent and selective antibreast cancer activity with IC50 values of 0.3, 0.2, 0.1, and 0.1 mu g/mL, respectively, against the ZR-75-1 cell lines. Compound 24 was 2- to 3-fold more potent than I against SK-BR-3 and ZR-75-1. Importantly, 21 exhibited high selectivity; it was 23 times more active against ZR-75-1 than MCF-7. Compound 20 had an approximately 12-fold ratio of SK-BR-3/MCF-7 selectivity. In addition, analogue 2 showed potent activity against it ZR-75-1 xenograft model, but not PC-3 and MDA-MB-231 xenografts, as well as high selectivity against breast cancer cell line compared with normal breast tissue-derived cell lines. Further development of lead compounds 19-21 and 24 as clinical trial candidates is warranted.

  4-Amino-2H-benzo[h]chromen-2-one (ABO) analogs were designed, synthesized, and evaluated for cytotoxic activity. Among all 4-substituted ABO analogs, cyclohexyl (12), N-methoxy-N-methylacetamide (14), and various aromatic derivatives (15-25 and 27) exhibited promising cell growth inhibitory activity with ED(50) values of 0.01-5.8 mu M against all tested tumor cell lines. The 4'-methoxyphenyl derivative (18) and 3'-methylphenyl derivative (24) showed the most potent antitumor activity against a broad range of cancer cell lines with ED(50) values of 0.01-76 mu M. Preliminary SAR results indicated that substitutions on nitrogen are critical to the antitumor potency. (C) 2010 Elsevier Ltd. All rights reserved.
