2-{4-[(7-Chloro-2-quinoxalinyl)oxy]phenoxy}propionic acid (XK469) is among the most highly and broadly active antitumor agents to have been evaluated in our laboratories and is currently scheduled to enter clinical trials in 2001. The mechanism or mechanisms of action of XK469 remain to be elaborated. Accordingly, an effort was initiated to establish a pharmacophore hypothesis to delineate the requirements of the active site, via a comprehensive program of synthesis of analogues of XK469 and evaluation of the effects of structural modification(s) on solid tumor activity. The strategy formulated chose to dissect the two-dimensional parent structure into three regions – I, ring A of quinoxaline; II, the hydroquinone connector linkage; and III, the lactic acid moiety – to determine the resultant in vitro and in vivo effects of chemical alterations in each region. Neither the A-ring unsubstituted nor the B-ring 3-chloro-regioisomer of XK469 showed antitumor activity. The modulating antitumor effect(s) of substituents of differing electronegativities, located at the several sites comprising the A-ring of region I, were next ascertained. Thus, a halogen substituent, located at the 7-position of a 2-{4-[(2-quinoxalinyl)oxy]phenoxy}propionic acid, generated the most highly and broadly active antitumor agents. A methyl, methoxy, or an azido substituent at this site generated a much less active structure, whereas 5-, 6-, 8-chloro-, 6-, 7-nitro, and 7-amino derivatives all proved to be essentially inactive. When the connector linkage (region II) of 1 was changed from that of a hydroquinone to either a resorcinol or a catechol derivative, all antitumor activity was lost. Of the carboxylic acid derivatives of XK469 (region III), i.e., CONH2, CONHCH3, CON(CH3)2, CONHOH, CONHNH2, CN, or CN4H (tetrazole), only the monomethyl- and N,N-dimethylamides proved to be active.

Four novel 4-(1H-imidazo[4,5-f]-1,10-phenanthrolin-2-yl)phenol derivatives 1-4 have been synthesized, and their G-quadruplex DNA-binding interactions, telomerase inhibition, antiproliferative activity, cell cycle arrest, and apoptotic induction were studied. All compounds show the preferential h-telo, c-myc, and c-kit2 G-quadruplex binding affinity and the G-quadruplex versus duplex selectivity. In the case of the same G-quadruplex target, the compound 1 exhibits better stabilization effect (DeltaTm) than the other three compounds and also gives 80.2% inhibition of telomerase activity at 7.5 muM. All compounds can promote selectively the formation of parallel G-quadruplex structure of both c-myc and c-kit2 without addition of any cations. Four compounds display the cytotoxicity activities against HeLa and HepG2 cells by MTT assay with IC50 values of about 10-6 and 10 -5 M, respectively, and cause a substantial decrease in the G 2/M-phase cell population and a significant increase in the number of apoptotic cells.

It is known that synthetic polymer plays a big role in various applications. One of its potentials is to remove heavy metal ions through single batch adsorption. Adsorption behavior and mechanism of synthetic polymer are the two main focuses in this research. The synthetic polymer of Poly(AN-co-AA) has been successfully polymerized, modified with hydroxylamine hydrochloride and removed Cd2+ and Pb2+. The poly(AN-co-AA) and amidoxime (AO) modified poly(AN-co-AA) were characterized by Fourier Transform Infrared Analysis (FTIR), microanalysis, Scanning Electron Microscopy (SEM) and Thermogravimetry (TGA). At pH 9, the percentage removal for Cd2+ (90%) and Pb2+ (98%) were the highest with adsorbent dosage at 4 gL?1 and 8 g L?1, respectively. The experimental data for Cd2+ (20 mg g?1) and Pb2+ (125 mg g?1) were fitted well by Sips and Freundlich isotherms model, respectively. The adsorption rate for both Cd2+ and Pb2+ were stated by using Lagergren pseudo-first order.

Glycogen phosphorylase (GP) plays a crucial role in the conversion of glycogen to glucose-1-phosphate (and in turn glucose) and is a promising target for therapeutic intervention in diabetes. In this study we synthesized new derivatives of 2-oxo-1,2-dihydropyridin-3-yl amides using a facile aminolysis reaction, in which different alkyl and aryl esters and amides are substituted at N-1 and C-3 of the heterocyclic ring. The in vitro inhibitory activity of compounds against glycogen phosphorylase was evaluated. From this series the most potent compound exhibits good GPa inhibition (IC50 = 6.3 muM). A preliminary study of these compounds showed that anti-GP activity was decreased by the incorporation of a C3-N carbonyl group and favored by increased lipophilicity.

In order to search for active and selective serotonin 5-HT7R antagonists among 3,5-disubstituted arylpiperazine-imidazolidine-2,4-diones, the role of the introduction/deletion and the mutual orientation of aromatic rings was analyzed. Chemical modifications of 2nd generation lead structure of 3-(3-(4-(diphenylmethyl)piperazin-1-yl)-2-hydroxypropyl)-5-(4-fluorophenyl)-5-methylimidazolidine-2,4-dione (2, KKB16) were performed. New derivatives (4-18) were designed and synthesized. X-ray crystallographic analysis of the representative compound 5-(4-fluorophenyl)-3-[2-hydroxy-3-(4-phenylpiperazin-1-yl)propyl]-5-methylimidazolidine-2,4-dione (3) was performed to support molecular modeling and SAR studies. The affinity for 5-HT7R, D2R and 5-HT1AR in radioligand binding assays for the entire series and ADME-Tox parameters in vitro for selected compounds (7, 10, and 13) were evaluated. Molecular docking and pharmacophore model assessment were performed. According to the obtained results, 5-methyl-5-naphthylhydantoin derivatives were found to be the new highly active 5-HT7R agents (Ki ? 5 nM) with significant selectivity over 5-HT1AR and D2R. On the contrary, the (1-naphthyl)piperazine moiety was gained with the potent dual 5-HT7R/5-HT1AR action (Ki: 11 nM/19 nM).
