  Synthesis and structure activity relationships of schweinfurthin indoles

  摘要：

  As part of a program to explore the biological activity of analogues of the natural schweinfurthins, a set of compounds has been prepared where an indole system can be viewed as a substitution for the resorcinol substructure of the schweinfurthin's D-ring. Twelve of these schweinfurthin indoles have been prepared and evaluated in the 60 cell line screen of the National Cancer Institute. While a range of activity has been observed, it is now clear that schweinfurthin indoles can demonstrate the intriguing pattern of activity associated with the natural stilbenes. In the best cases, these indole analogues display both potency and differential activity across the various cell lines comparable to the best resorcinol analogues. (C) 2014 Elsevier Ltd.

  Synthesis of Indole Analogues of the Natural Schweinfurthins

  摘要：

  An interest in the schweinfurthins, natural stilbenes with significant antiproliferative activity, has prompted efforts to prepare a set of indole analogues. To approach the desired compounds through a Horner-Wadsworth-Emmons condensation, new indole derivatives bearing a phosphonomethyl substituent in the B-ring were required. The parent indole system with the necessary substitution pattern was obtained through Stobbe condensation and cyclization. A prenyl substituent was incorporated at the C3 position of a 4,6-disubstituted indole through a highly regioselective electrophilic aromatic substitution reaction, while metalation and alkylation provided the C2-prenylated indole. After introduction of the phosphonate group through classical reactions, the new indole phosphonates were found to undergo the desired condensation with nonracemic aldehydes representing the schweinfurthin left half. This approach provides facile access to new heteroaromatic analogues of the natural schweinfurthins and should be applicable to many other natural stilbenes as well.
