Synthesis and anticancer activity of some novel 2-phenazinamine derivatives
摘要:
In this study, we report the synthesis and spectral characterization of a novel series of 2-phenazinamine derivatives. In vitro evaluation for their anticancer activity toward cultured K562 (human chronic myelogenous leukemia), HepG2 (human hepatocellular carcinoma), MGC803 (human gastric carcinoma), HCT116 (human colorectal carcinoma), MCF7 (human breast adenocarcinoma) cell lines, as well as 293T (epithelial cells from human embryo kidney) non-cancer cell was carried out. The compounds 4, 7,16 and 19 showed good positive anticancer activity in vitro. In particular, compound 4, 2-chloro-N-(phenazin-2-yl)benzamide, possessed a potent anticancer effect comparable to cisplatin against both 1<562 and HepG2 cancer cells but was very low or had no effect against 293T non-cancer cell. Preliminary anticancer mechanism of 4 was investigated by cell apoptosis assays compared with cisplatin using flow cytometry. (C) 2013 Elsevier Masson SAS. All rights reserved.
The nitration of 1-methoxy- and 1-aminophenazine gives the 4-nitro derivatives from which various 1,4-disubstituted phenazines have been obtained. Data on the absorption spectra of these compounds are recorded.

Provided are methods and compositions for reducing superoxide anions such that a prophylactic or therapeutic effect against conditions associated with excess oxidative stress achieved. The compositions and methods provide for reducing inflammation and for enhancing lifespan of eukaryotic organisms. A screen for identifying compounds that can be used in these methods is also provided.
