(E)-4-(3,5-dimethoxystyryl)phenyl acetate (Cmpd1) is a resveratrol analog that preferentially inhibits glioma, breast, and pancreatic cancer cell growth, with IC50 values of 6-19 μM. Notably, the human U251MG glioblastoma tumor line is the most sensitive, with an IC50 of 6.7 μM, compared with normal

A major challenge to broadening oncology applications for inhibitors of the ubiquitin-proteasome system (UPS) is the identification of UPS-dependent cancer pathways predictive of tumors responsive to peptidomimetic inhibitors of its 20S core protease activity. To inform clinical studies evaluating

Background: Inflammation is a key element in tumor progression, over time, persistent inflammation causes damage to DNA and leads to cancer. The relationship between chronic inflammation and tumor development is well established and

Aminoflavone (5-amino-2,3-fluorophenyl)-6,8-difluoro-7-methyl-4H-1-benzopyran-4-one) (NSC 686288) is a candidate for possible advancement to phase I clinical trial. Aminoflavone has a unique activity profile in the NCI 60 cell lines (COMPARE analysis;

OBJECTIVE To examine the effects of combined treatment of oxaliplatin and phosphatidylinositol 3'-kinase inhibitor, 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one (LY294002) for gastric cancer. METHODS Cell viability was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide

OBJECTIVE Aminoflavone (5-amino-2,3-fluorophenyl)-6,8-difluoro-7-methyl-4H-1-benzopyran-4-one; AF; NSC 686288) is a novel anticancer agent with a unique pattern of growth inhibitory activity in the National Cancer Institute (NCI) 60 tumor cell line screen. Phase I clinical trials with AF will begin

Apigenin (4',5,7-trihydroxyflavone, 5,7-dihydroxy-2-(4-hydroxyphenyl)-4H-1-benzopyran-4-one) is a flavonoid found in many fruits, vegetables, and herbs, the most abundant sources being the leafy herb parsley and dried flowers of chamomile. Present in dietary sources as a glycoside, it is cleaved in

Mammalian target of rapamycin (mTOR), a serine/threonine kinase, regulates cell growth and proliferation in part via the activation of p70 S6 kinase (S6K). Rapamycin is an antineo-plastic agent that, in complex with FKBP12, is a specific inhibitor of mTOR through interaction with its

Aminoflavone (4H-1-benzopyran-4-one, 5-amino-2-(4-amino-3-fluorophenyl)-6,8-difluoro-7-methyl; NSC 686288) demonstrates differential antiproliferative activity in the National Cancer Institute's anticancer drug screen. We demonstrate here that MCF-7 human breast cancer cells are sensitive to

The present studies were performed to elucidate the mechanism of cytotoxicity of the aminoflavone analog (5-amino-2,3-fluorophenyl)-6,8-difluoro-7-methyl-4H-1-benzopyran-4-one (AF; NSC 686288), a novel flavone with potent in vitro and in vivo antiproliferative activity against a number of human

Most current anticancer drugs have shown excellent therapeutic effects on human oral squamous cell carcinoma (OSCC), but they also produce potent cytotoxicity in normal oral keratinocytes. This review article summarizes our extensive research of tumor specificity and keratinocyte toxicity of nine

Cellular senescence contributes to tumor regression through both cell autonomous and non-autonomous mechanisms. Drugs inducing cancer cell senescence and modulating senescence-associated secretory phenotype (SASP) render advantage to the cancer treatment. Breast cancer remains the second most cause

Baicalein (5,6,7-trihydroxy-2-phenyl-4H-1-benzopyran-4-one) is a flavonoid compound derived from the roots of Scutellaria baicalensis. It has historically been used in anti-oxidant, anti-virus, anti-bacteria, anti-inflammatory and anti-allergic therapies. Recently, baicalein has been found to

A new series of fluoro-, methoxyl-, and amino-substituted isoflavones have been synthesized as potential antitumor agents based on structural similarities to known flavones and isoflavones (quercetin and genistein respectively) and antitumor 2-phenylbenzothiazoles. Target compounds were synthesized

Quercetin is a member of a group of naturally occurring compounds, the flavonoids, which have a common flavone nucleus composed of two benzene rings linked through a heterocyclicpyrone ring. Quercetin is found in various plants, food products, and dyes of natural origin. The estimated average daily
