Polycyclic aromatic compounds as anticancer agents: structure–activity relationships of chrysene and pyrene derivatives
摘要:
A large number of diamides and diamines were synthesized using 6-amino chrysene and 1-amino pyrene as starting materials. A structure-activity study with cis-platinum as internal control against animal and human tumor lines was carried out in vitro. This study indicated that the in vitro cytotoxicity toward these lines depends on the functionality present in the molecules. The diamino compounds were found to be more potent than the diamides, and these were equally active irrespective of the end heterocyclic group, whereas the activity of the diamides was strongly dependent on the terminal unit. In general, the diamides containing chrysene as the chromophore were more active than those with a pyrene ring. The size of the end heterocyclic ring, along with the nature of the spacer connecting the polycyclic ring to the heterocyclic ring, seemed to affect the biological activity in certain cell lines. Hemolysis experiments on a lead compound established that it had activities similar to those described for membrane-stabilizing agents. This agent also demonstrated the capacity to produce differentiation in leukemia cell lines. (C) 2001 Elsevier Science Ltd. All rights reserved.
Sepsis, a systemic inflammatory response, caused by pathogenic factors including microorganisms, has high mortality and limited therapeutic approaches. Herein, a new solubleepoxidehydrolase (sEH) inhibitor series comprising a phenyl ring connected to a memantyl moiety via a urea or amide linkage has been designed.

Polycyclic aromatic hydrocarbons are widespread in nature with a toxicity range from non-toxic to extremely toxic. A series of pyrenyl derivatives has been synthesized following a four-step strategy where the pyrene nucleus is attached with a basic heterocyclic moiety through a carbon linker. Virtual screening of the physicochemical properties and druggability has been carried out. The cytotoxicity of the compounds (1-8) have been evaluated in vitro against a small panel of human cancer cell lines which includes two liver cancer (HepG2 and Hepa 1-6), two colon cancer (HT-29 and Caco-2) and one each for cervical (HeLa) and breast (MCF-7) cancer cell lines. The IC50 data indicate that compound 6 and 8 are the most effective cytotoxic agents in the present set of pyrenyl derivatives, suggesting that having a 4-carbon linker is more effective than a 5-carbon linker and the presence of amide carbonyl groups in the linker severely reduces the efficacy of the compound. The compounds showed selectivity toward cancer cells at lower doses (<5 mu M) when compared with the normal hepatocytes. The mechanism of action supports the cell death through apoptosis in a caspase-independent manner without cleavage of poly (ADP-ribose) polymerase (PARP), even though the compounds cause plasma membrane morphological changes. The compounds, whether highly cytotoxic or mildly cytotoxic, localize to the membrane of cells. The compounds with either a piperidine ring (6) or an N-methyl piperazine (8) in the side chain were both capable of circumventing the drug resistance in SKOV3-MDR1-M6/6 ovarian cancer cells overexpressing P-glycoprotein. Qualitative structure-activity relationship has also been studied. (C) 2014 Published by Elsevier Masson SAS.
