butyric acid/悪性腫瘍

Pancreatic cancer has a high mortality rate and alcoholism is a risk factor independent of smoking. We have shown that nicotinic acetylcholine receptors (nAChR) regulate pancreatic ductal epithelia and pancreatic ductal adenocarcinoma (PDAC) cells in an autocrine fashion by stimulating their

Butyric acid, a short chain fatty acid (SCFA), is a natural component of the animal metabolism. Physiological concentrations induce multiple and reversible biological effects. They concern regulatory mechanisms of gene expression conducing to promote markers of cell differentiation, apoptosis and

BACKGROUND Anticancer properties of artemisinin and its derivatives have been shown in many experiments. OBJECTIVE Addition of butyric acid, miconazole, and iron to this traditional drug has been done in order to enhance its anticancer potency. METHODS Cell lines 5637 and 4T1, were cultivated and

Due to an oversight one of the author's name was published wrong in the article entitled "Design, Synthesis and Biological Evaluation of a Phenyl Butyric Acid Derivative, N-(4-chlorophenyl)-4- phenylbutanamide: A HDAC6 Inhibitor with Anti-proliferative Activity on Cervix Cancer and Leukemia

A novel derivative of butyric acid, pivalyloxymethyl butyrate (AN-9) has been shown, in vitro, to: (a) induce cytodifferentiation and inhibit the proliferation of leukemic cells; (b) inhibit the growth and formation of Lewis lung carcinoma colonies in semi-solid agar. AN-9 affect cells at about

The anticarcinogenic activity of synthetic 1-O-octadecyl-2,3-dibutyroilglycerol (D-SCAKG) in tumor-cell line of colonocytes (SW620) was performed. The effect of the previously digested D-SCAKG under in vitro intestinal conditions was compared to the bioactivity of non-digested D-SCAKG.

L-2,4-Diamino[4-11C]butyric acid (DAB) was synthesized by an enzyme catalysed carrier added (0.1 micromol KCN) reaction of hydrogen [11C]cyanide with O-acetyl-L-serine followed by reduction. L-[11C]DAB was obtained with a radiochemical purity higher than 96% and with a decay corrected radiochemical

Butyric acid has two contrasting functional roles. As a product of fermentation within the human colon, it serves as the most important energy source for normal colorectal epithelium. It also promotes the differentiation of cultured malignant cells. A switch from aerobic to anaerobic metabolism

Seven differences in the polypeptide species of parental Syrian hamster embryo cells and cells of the highly tumorigenic derivative cell line BP6T were identified previously by employing the technique of two-dimensional polyacrylamide gel electrophoresis (Leavitt, J. and Moyzis, R. (1978) J. Biol.

The anti-colon cancer effect of dietary fibre results in part from its fermentation into the short-chain fatty acid butyric acid (BA) by intestinal microflora. BA has potent anti-colon cancer properties owing to its ability to induce apoptosis in colon cancer cells. The colon is not the only

The synthesis and biological activities of acidic, basic and neutral types of butyric acid (BA) prodrugs possessing increased aqueous solubility are described. The compounds are butyroyloxyalkyl derivatives of carboxylic acids, which possess functionalities suitable for aqueous solubilization. The

Previously we have shown that pivaloyloxymethyl butyrate (AN-9), a pro-drug of butyric acid (BA), is a differentiation-inducing agent in a variety of cells. In this report, we demonstrate that AN-9 is a cytostatic but not cytotoxic agent in a myelomonocytic cell line (WEHI); thus, the cells were

A derivative of butyric acid, pivalyloxymethyl butyrate (AN-9), inhibited the proliferation and induced apoptosis of mouse monocytic leukaemia Mm-A cells, although sodium butyrate, but not AN-9, induced differentiation of the cells. AN-9 and DNA-specific antineoplastic agents synergistically

Activated microglia may be detrimental to neuronal survival in a number of neurodegenerative diseases. Thus, strategies that reduce microglial neurotoxicity may have therapeutic benefit. Stimulation of group II metabotropic glutamate (mGlu) receptors on rat primary microglia with the specific group

The mechanism for inactivation of the KIP family cyclin-dependent kinase inhibitor (CDKI) genes, the p21, p27, and p57 genes, in gastric cancer cells was tested by treating the cells with either the DNA demethylation agent, 5-aza-2'-deoxycytidine or the histone deacetylase inhibitor, n-butyric acid
