Four prenylated flavonoids including isosophoranone, sophoraflavanone G, alopecurone J, alopecurone P and a resveratrol derivative HPD (2-(4-hydroxyphenyl)-2,3-dihydrobenzo[b] furan-3,4,6-triol), were isolated from the roots of Sophora pachycarpa. The cytotoxic activity of obtained compounds was evaluated against A2780, A549, HeLa, and HCT116 human cancer cell lines. We also evaluated their his...
Lapatinib, a dual EGFR/HER2 tyrosine kinase inhibitor, has been shown to improve the survival rate of patients with advanced HER2-positive breast cancers. However, the off-target activity of lapatinib in inducing EGFR expression without tyrosine kinase activity was demonstrated to render HER2-negative breast cancer cells more metastatic, suggesting a limitation to the therapeutic effectiveness ...
Histone deacetylase (HDAC) inhibitors [1] are FDA approved for the treatment of lymphoid malignancies, including cutaneous T cell lymphoma (romidepsin, vorinostat) and multiple myeloma (panobinostat). While these agents have also undergone extensive clinical testing alone and in combination with a variety of other agents in solid tumors, clinical activity compelling enough to lead to FDA approv...
Clinical management of abdominal aortic aneurysm (AAA) is currently limited to elective surgical repair because an effective pharmacotherapy is still awaited. Inhibition of histone deacetylase (HDAC) activity could be a promising therapeutic option in cardiovascular diseases. We aimed to characterise HDAC expression in human AAA and to evaluate the therapeutic potential of class I and IIa HDAC ...
Tumors grow in the presence of antigen-specific T cells, suggesting the existence of intrinsic cancer cell escape mechanisms. We hypothesized that a histone deacetylase (HDAC) inhibitor could sensitize tumor cells to immunotherapy because this class of agents has been reported to increase tumor antigen expression and shift gene expression to a proapoptotic milieu in cancer cells. To test this q...
Aberrant histone deacetylase (HDAC) activity is frequent in human leukemias. However, while classical, NAD(+)-independent HDACs are an established therapeutic target, the relevance of NAD(+)-dependent HDACs (sirtuins) in leukemia treatment remains unclear. Here, we assessed the antileukemic activity of sirtuin inhibitors and of the NAD(+)-lowering drug FK866, alone and in combination with tradi...
BACKGROUND Compound targeting histone deacetylase (HDAC) represents a new era in molecular cancer therapeutics. However, effective HDAC inhibitors for the treatment of solid tumors remain to be developed. METHODOLOGY/PRINCIPAL FINDINGS Here, we propose a novel HDAC inhibitor, N-Hydroxy-4-(4-phenylbutyryl-amino) benzamide (HTPB), as a potential chemotherapeutic drug for solid tumors. The HDAC ...
Chronic obstructive pulmonary disease (COPD) is a common chronic inflammatory disease of the lungs with little or no response to glucocorticoids and a high level of oxidative stress. Histone deacetylase (HDAC) activity is reduced in cells of cigarette smokers, and low concentrations of theophylline can increase HDAC activity. We measured the effect of theophylline on HDAC activity and inflammat...
Inhibiting histone deacetylase (HDAC) activity modulates the epigenetic status of cells, resulting in an alteration of gene expression and cellular function. Here, we investigated the effects of HDAC inhibitors on mouse embryonic stem (ES) cells. The HDAC inhibitors trichostatin A, suberoylanilide hydroxamic acid, sodium butyrate, and valproic acid induced early differentiation of mouse ES cell...
Tumor necrosis factor-(TNF-)-α upregulates plasminogen activator inhibitor-(PAI-) 1 expression in pleural mesothelial cells (PMCs), contributing to fibrin deposition and pleural fibrosis. Histone deacetylases (HDACs) have been found implicated in fibrogenesis. However, the roles of TNF-α or HDAC in the regulation of PAI-1 expression have not been well investigated. We aimed to examine the effec...
