Potent Antitumor 9-Anilinoacridines and Acridines Bearing an Alkylating N-Mustard Residue on the Acridine Chromophore: Synthesis and Biological Activity
摘要:
A series of 9-anilinoacridine and acridine derivatives bearing an alkylating N-mustard residue at C4 of the acridine chromophore were synthesized. The N-mustard pharmacophore was linked to the C4 of the acridine ring with an O-ethyl ( O-C-2), O-propyl ( O-C-3), or O-butyl ( O-C-4) spacer. It revealed that all newly synthesized compounds were very potent cytotoxic agents against human leukemia and various solid tumors in vitro. These agents did not exhibit cross-resistance against vinblastine-resistant ( CCRF-CEM/VBL) or taxol-resistant ( CCRF-CEM/taxol) cells. It also showed that these agents were DNA cross-linking agents rather than topoisomerase II inhibitors. Of these agents, compounds 27a and 27c were shown to have potent antitumor activity in nude mice bearing the human breast carcinoma MX-1 xenograft. The therapeutic efficacies of these two agents are comparable to that of taxol.

A series of 9-anilinoacridines having an alkylating N-mustard pharmacophore on both anilino (C-3' or C-4') and acridine (C-4) rings with O-ethyl (O-C-2) or O-butyl (O-C-4) spacer were synthesized to evaluate their cytotoxicity against human lymphoblastic leukemia (CCRF-CEM) cell growth in vitro. It was revealed that these conjugates exhibited significant in vitro cytotoxicity. Among these agents, compound 13 was the most cytotoxic with IC50 value of 1.3 nM and is as potent as taxol (IC50 = 1.1 nM). The structure-activity relationship study showed that the length of the spacer and the position of the substituent do affect their cytotoxicity. (C) 2008 Elsevier Masson SAS. All rights reserved.
