PMID: 16504166
BMC Chem Biol. 2006 Feb 27;6:2. doi: 10.1186/1472-6769-6-2.

BACKGROUND: A recent crystal structure of monastrol in a ternary complex with the kinesin Eg5 motor domain highlights a novel, induced-fit drug binding site at atomic resolution. Mutational obliteration of the monastrol binding site results in a monastrol-resistant, but...

Transcriptional profiling of the effects of 25-hydroxycholesterol on human hepatocyte metabolism and the antiviral state it conveys against the hepatitis C virus.

BMC chemical biology

Pezacki JP, Sagan SM, Tonary AM, Rouleau Y, Bélanger S, Supekova L, Su AI.
PMID: 19149867
BMC Chem Biol. 2009 Jan 16;9:2. doi: 10.1186/1472-6769-9-2.

BACKGROUND: Hepatitis C virus (HCV) infection is a global health problem. A number of studies have implicated a direct role of cellular lipid metabolism in the HCV life cycle and inhibitors of the mevalonate pathway have been demonstrated to...

Enhancement of intracellular gamma-tocopherol levels in cytokine-stimulated C3H 10T1/2 fibroblasts: relation to NO synthesis, isoprostane formation, and tocopherol oxidation.

BMC chemical biology

Tanaka Y, Wood LA, Cooney RV.
PMID: 17608946
BMC Chem Biol. 2007 Jul 03;7:2. doi: 10.1186/1472-6769-7-2.

BACKGROUND: Stimulation of C3H 10T1/2 murine fibroblasts with interferon-gamma(IFN) and bacterial lipopolysaccharide (LPS) generates reactive oxygen and nitrogen species leading to DNA damage, lipid oxidation, and tocopherol oxidation. The tocopherols possess unique chemical and biological properties that suggest they...

Catalytic inhibition of topoisomerase II by a novel rationally designed ATP-competitive purine analogue.

BMC chemical biology

Chène P, Rudloff J, Schoepfer J, Furet P, Meier P, Qian Z, Schlaeppi JM, Schmitz R, Radimerski T.
PMID: 19128485
BMC Chem Biol. 2009 Jan 07;9:1. doi: 10.1186/1472-6769-9-1.

BACKGROUND: Topoisomerase II poisons are in clinical use as anti-cancer therapy for decades and work by stabilizing the enzyme-induced DNA breaks. In contrast, catalytic inhibitors block the enzyme before DNA scission. Although several catalytic inhibitors of topoisomerase II have...

DG-AMMOS: a new tool to generate 3d conformation of small molecules using distance geometry and automated molecular mechanics optimization for in silico screening.

BMC chemical biology

Lagorce D, Pencheva T, Villoutreix BO, Miteva MA.
PMID: 19912625
BMC Chem Biol. 2009 Nov 13;9:6. doi: 10.1186/1472-6769-9-6.

BACKGROUND: Discovery of new bioactive molecules that could enter drug discovery programs or that could serve as chemical probes is a very complex and costly endeavor. Structure-based and ligand-based in silico screening approaches are nowadays extensively used to complement...

Mitotic slippage in non-cancer cells induced by a microtubule disruptor, disorazole C1.

BMC chemical biology

Xu FL, Rbaibi Y, Kiselyov K, Lazo JS, Wipf P, Saunders WS.
PMID: 20181182
BMC Chem Biol. 2010 Feb 11;10:1. doi: 10.1186/1472-6769-10-1.

BACKGROUND: Disorazoles are polyene macrodiolides isolated from a myxobacterium fermentation broth. Disorazole C1 was newly synthesized and found to depolymerize microtubules and cause mitotic arrest. Here we examined the cellular responses to disorazole C1 in both non-cancer and cancer...

Development of an HPLC method for determination of pentachloronitrobenzene, hexachlorobenzene and their possible metabolites.

BACKGROUND: Wnt/β-catenin-mediated gene transcription plays important roles in a wide range of biological and pathophysiological processes including tumorigenesis where β-catenin-mediated transcription activity frequently elevates. TRABID, a deubiquitinase, was shown to have a positive Wnt/β-catenin-mediated gene transcription and hence holds...
