Synthesis and in vitro antitumor activity of novel scopoletin derivatives
摘要:
Twenty scopoletin derivatives were developed by a systematic combinatorial chemical approach and their chemical structures were confirmed by MS, IR, H-1 NMR spectra and elemental analysis. Primary screening against mammary (MCF-7 and MDA-MB 231) and colon (HT-29) carcinoma cells indicated that five compounds (8d, 8g, 8j, 11b and 11g) displayed high antitumor potencies with IC50 values below 20 mu M whereas scopoletin showed IC50 values above 100 mu M. Moreover, the most promising compound 11g was more active than 5-fluorouracil. These results clearly indicated that the modification of the scopoletin structure could greatly increase its antitumor activity in vitro. (c) 2012 Elsevier Ltd. All rights reserved.

A convenient synthetic method for N-arylformamide derivatives was successfully developed by reacting α-iodo-N-arylacetamides with formamide. This method was applicable to α-iodo-N-arylacetamide substrates bearing electron-donating or electron-withdrawing groups, N-(benzo[d][1,3]dioxol-5-yl)-2-iodoacetamide, 2-iodo-N-(pyridin-2-yl)acetamide, and 2-iodo-N-(naphthalen-4-yl)acetamide to give the corresponding
