beta glucosidase/neoplasms

8-Hydroxyquinoline derivatives are metal-binding compounds that have recently attracted interest as therapeutic agents for cancer therapy. In this scenario, we designed and synthesized three new glucoconjugates, 5,7-dichloro-8-quinolinyl-β-D-glucopyranoside, 5-chloro-8-quinolinyl-β-D-glucopyranoside

We describe a novel version of antibody-directed enzyme prodrug therapy (ADEPT), with the use of amygdalin as prodrug. Amygdalin is a naturally occurring cyanogenic glycoside, which can be cleaved by sweet almond beta-glucosidase to yield free cyanide. If amygdalin could be activated specifically at

Minor ginsenosides, such as compound K, Rg₃(S), which can be produced by deglycosylation of ginsenosides Rb₁, showed strong anti-cancer effects. However, the anticancer effects of gypenoside LXXV, which is one of the deglycosylated shapes of ginsenoside Rb₁, is still unknown due to the rarity of its

BACKGROUND Iridoids belong to a group of monoterpene compounds with cyclopentane ring and found as mostly the glycoside forms in nature. They act primarily as the defense substances and found in various medicinal plants. OBJECTIVE Although many iridoids exhibit anti-inflammatory and anticancer

Experiments are described in which four transplantable rodent tumors (L1210 lymphoid leukemia, P388 lymphocytic leukemia, B16 melanoma, and Walker 256 carcinosarcoma) were used to investigate the antitumor activity of amygdalin MF. Amygdalin MF was given alone and in combination with

Amygdalin, the gentiobioside derivative of mandelonitrile commonly referred to as Laetrile, is presently under intensive investigation as a potential cancer chemotherapeutic agent. Because of this interest, we investigated the activity of beta-glucosidases that cleave glucose from amygdalin and from

The resistance to therapy is a major clinical challenge for advanced stage breast cancer. Identification of novel potential therapeutic targets is needed to overcome chemoresistance. In this work, we identified a target that was critically involved in breast cancer growth and chemoresistance. We

We hypothesized that soy phytochemicals may have immunomodulatory properties that may affect prostate carcinogenesis and progression. A randomized, phase II trial was conducted in 32 patients with prostate cancer with asymptomatic biochemical recurrence but no measurable disease on standard staging

A pancreas cancer-associated antigen (PCAA) was identified and isolated from ascites fluid of human pancreatic cancer. Purified PCAA was homogeneous as determined by polyacrylamide gel electrophoresis. PCAA was a glycoprotein with a molecular weight of approximately 1,000,000 and consisted of 20%

The present study assessed the cytotoxicity of sodium meta-arsenite (SMA) on telomere shortening and cellular apoptosis in human A-549, MDA-MB-231 and U87-MG cancer cell lines. Following 2 weeks of 1 μM SMA treatment, population doubling time (PDT) was significantly (P < .05) increased by the

Diet-induced changes in fecal excretion of secondary bile acids, certain neutral sterols, and bacterial enzyme activities are known to play a role in colon cancer development. Dietary fish oil (FO) has been implicated as a protective agent in colon carcinogenesis. In the present study, the effects

Ginseng is one of the most commonly used adaptogens. Transformation into the minor ginsenosides produces compounds with more effective action. Beauveria bassiana, a teleomorph of Cordyceps bassiana, is a highly efficient producer of mammalian steroids and produces large amounts of sugar-utilizing

Cereal fiber may reduce the risk of colorectal cancer by diluting colonic contents due to increased fecal output, by accelerating intestinal transit, by increasing fecal frequency and by altering bacterial metabolism. The effects of whole-meal rye bread on some putative colon cancer risk markers

To identify genes involved in the formation of genetic tumors in interspecific hybrids (F1) between Nicotiana glauca and N. langsdorffii, genetic tumor-related cDNA probes were obtained by a subtractive hybridization procedure and used to screen libraries of genetic tumor cDNAs. As a result, 17
