Evaluation of novel aryloxyalkyl derivatives of imidazole and 1,2,4-triazole as heme oxygenase-1 (HO-1) inhibitors and their antitumor properties
摘要:
A novel series of aryloxyalkyl derivatives of imidazole and 1,2,4-triazole, 17-31, was designed and synthesized as inhibitors of heme oxygenase-1 (HO-1) and heme oxygenase-2 (HO-2). Some of these compounds were found to be good inhibitors of HO-1, in particular those carrying an imidazole moiety as azolyl group and a 3-bromo or 4-iodophenyl as aryl moiety. The most potent compounds 6 and 30 were selected and studied for their antitumor properties in a model of LAMA-84 R cell line overexpressing HO-1 and resistant to imatinib mesylate (IM), a tyrosine-kinase inhibitor used in the treatment of multiple types of cancer, most notably Philadelphia Chromosome positive (Ph+) Chronic Myelogenous Leukemia (CML). Results show that both 6 and 30 sensitized LAMA-84 R cell line to antitumor properties of IM. (C) 2013 Elsevier Ltd. All rights reserved.

Disclosed are compounds of the general formula (I):
TC
n
D (I),
compositions comprising an effective amount of said compounds either alone or in combination with other chemotherapeutic agents, and methods useful for treating or preventing cancer and for inhibiting tumour tissue growth. These compounds attenuate the oxidative damage associated with increased heme-oxygenase activity and can reduce cell proliferation in transformed cells. In addition, the described compounds and compositions are useful as neuroprotectants and for treating or preventing neurodegenerative disorders and other diseases of the central nervous system.
The invention provides compounds of the formula (I) having protein kinase B inhibiting activity:
Also provided are pharmaceutical compositions containing the compounds, methods for preparing the compounds and their use as anticancer agents.
