Effect of linkage geometry on biological activity in thiourea- and guanidine-substituted acridines and platinum–acridines
摘要:
Novel thiourea- and guanidine-modified acridine-4-carboxamides (4, 7) and a corresponding platinum intercalator conjugate (4') have been synthesized and evaluated as cytotoxic agents in human promyelocytic leukemia, HL-60, and a non-small cell lung cancer, NCI-H460. Modi. cation of thiourea sulfur in derivative 4 with a DNA platinating moiety, giving 4', resulted in a pronounced cytotoxic enhancement, and the conjugate proved to be the most active of the newly synthesized compounds in NCI-H460 cells. Conjugate 4' represents a new chemotype with potential applications in the treatment of chemoresistant tumors. (c) 2008 Elsevier Ltd. All rights reserved.

antileukemic activity, with substituents at nearly all acridine positions proving acceptable. The compounds also show remarkable activity against the Lewis lung solid tumor in vivo, with several analogues capable of effecting 100% cures of the advanced disease. The broad SAR and high solid-tumor activity of the 9-acridine-4-carboxamides imply they should be considered as a completely new class of antitumor
