Language：English Publishing type：Research paper (scientific journal)

A series of compounds containing an N-(7-indolyl)benzenesulfonamide pharmacophore was synthesized and evaluated as a potential antitumor agent. Cell cycle analysis with P388 murine leukemia cells revealed that there were two different classes of potent cell cycle inhibitors; one disrupted mitosis and the other caused G1 accumulation. Herein described is the SAR summary of the substituent patterns on this pharmacophore template. (C) 2000 Elsevier Science Ltd. All rights reserved.

A general method for acylation of ndoles at the 3-position with Acyl chlorides in the presence of dialkylaluminum chloride Reviewed

Okauchi T., Itonaga M., Minami T., Takashi O., Kitoh K., Yoshino H.

Organic Letters 2 ( 10 ) 1485 - 1487 2000.05

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

(Matrix presented) Indoles are selectively acylated at the 3-position in high yields on treatment with a wide variety of acyl chlorides in CH2CI2 in the presence of diethylaluminum chloride or dimethylaluminum chloride. The reaction proceeds under mild conditions and is applicable to indoles bearing various functional groups without NH protection.
