A cyanogenic glycoside found in the seeds of Rosaceae.
Hydrogen cyanide (HCN); A toxic liquid or colorless gas. It is found in the smoke of various tobacco products and released by combustion of nitrogen-containing organic materials.
A plant genus in the family ROSACEAE, order Rosales, subclass Rosidae. It is best known as a source of edible fruits such as apricot, plum, peach, cherry, and almond.
Botanically, a type of single-seeded fruit in which the pericarp enclosing the seed is a hard woody shell. In common usage the term is used loosely for any hard, oil-rich kernel. Of those commonly eaten, only hazel, filbert, and chestnut are strictly nuts. Walnuts, pecans, almonds, and coconuts are really drupes. Brazil nuts, pistachios, macadamias, and cashews are really seeds with a hard shell derived from the testa rather than the pericarp.
An exocellulase with specificity for a variety of beta-D-glycoside substrates. It catalyzes the hydrolysis of terminal non-reducing residues in beta-D-glucosides with release of GLUCOSE.

The cyanogenic glucoside, prunasin (D-mandelonitrile-beta-D-glucoside), is a novel inhibitor of DNA polymerase beta. (1/26)

A DNA polymerase beta (pol. beta) inhibitor has been isolated independently from two organisms; a red perilla, Perilla frutescens, and a mugwort, Artemisia vulgaris. These molecules were determined by spectroscopic analyses to be the cyanogenic glucoside, D-mandelonitrile-beta-D-glucoside, prunasin. The compound inhibited the activity of rat pol. beta at 150 microM, but did not influence the activities of calf DNA polymerase alpha and plant DNA polymerases, human immunodefficiency virus type 1 reverse transcriptase, calf terminal deoxynucleotidyl transferase, or any prokaryotic DNA polymerases, or DNA and RNA metabolic enzymes examined. The compound dose-dependently inhibited pol. beta activity, the IC(50) value being 98 microM with poly dA/oligo dT(12-18) and dTTP as the DNA template and substrate, respectively. Inhibition of pol. beta by the compound was competitive with the substrate, dTTP. The inhibition was enhanced in the presence of fatty acid, and the IC(50) value decreased to approximately 40 microM. In the presence of C(10)-decanoic acid, the K(i) value for substrate dTTP decreased by 28-fold, suggesting that the fatty acid allowed easier access of the compound to the substrate-binding site.  (+info)

Pharmacological properties of traditional medicines (XXVII). Interaction between Ephedra Herb and Gypsum under hyperthermal conditions in rats. (2/26)

There are many important considerations in the interactions among the herbal constituents in a prescription of traditional Chinese medicine (TCM). Ephedra Herb [Chinese characters: see text] (Eph) is described a warm and acrid agent in TCM. The combination of Eph and Gypsum [Chinese characters: see text] (Eph-Gyp) shows specific actions in patients with different body temperatures. Previous reports suggested that Gypsum prevents the thermogenesis effect induced by ephedrine at an ambient temperature of 22 degrees C. In this investigation, the properties of Eph-Gyp in hyperthermal rats were studied in detail. It was shown that Gypsum Extract (GyE) enhanced the thermogenesis of Eph in hyperthermal rats, although not in normal rats. The results support not only the opposite actions of Eph-GyE but also the clinical differences in the symptomatic patterns of body temperature for Makyo-Kanseki-To [Chinese characters: see text] and Dai-Seiryu-To [Chinese characters: see text].  (+info)

Reverse-phase HPLC separation of D-amygdalin and neoamygdalin and optimum conditions for inhibition of racemization of amygdalin. (3/26)

In boiling aqueous solution, D-amygdalin usually begins to convert into neoamygdalin in 3 min and more than 30% of the initial D-amygdalin is found as neoamygdalin after 30 min. In this report, we establish methods for simple HPLC analysis and the inhibition of D-amygdalin conversion. D-Amygdalin and its conversion product, neoamygdalin, were clearly separated on reverse-phase column chromatography by an optimized eluent of 10 mM sodium phosphate buffer (pH 3.8) containing 6% acetonitrile. Linearity for analyzing D-amygdalin and neoamygdalin was observed in the range from 0.05 to 0.5 mM. The detection limits for D-amygdalin and neoamygdalin were ca. 5 microM per injected amount. We found that D-amygdalin conversion was completely inhibited by adding 0.05% citric acid to the aqueous solution before boiling. To prevent the loss of pharmaceutical potency of Tonin, we applied this method to measure the conversion rate of D-amygdalin. We confirmed that D-amygdalin conversion in Tonin is effectively inhibited by acidic boiling solution with 0.1% citric acid.  (+info)

Failure of amygdalin to arrest B16 melanoma and BW5147 AKR leukemia. (4/26)

Parenteral amygdalin was found to be ineffective in C57BL/6 mice with B16 melanoma and in AKR mice with BW5147 lymphatic leukemia, in doses ranging from 50 to 5000 mg/kg.  (+info)

Cellulase of Neurospora crassa. (5/26)

Mycelia and ungerminated conidia of Neurospora crassa were found to secrete extracellular endocellulase (EC 3.2.1.4). A simple induction system of potassium phosphate buffer (ph 6.0) plus inducer relied on the internal metabolic reserves of conicia or mycelia to provide energy and substrates for protein synthesis. Buffer concentration for optimum enzyme production was 100 mM, but at higher buffer concentrations enzyme production was inhibited. Cellobiose was clearly the best inducer, with an optimum effect from 0.05 to 1 mM. In deionized water, cellulase remained mostly associated with the cell, but a variety of salts stimulated the release of cellulase into the medium.  (+info)

Positive selection on a high-sensitivity allele of the human bitter-taste receptor TAS2R16. (6/26)

BACKGROUND: During periods of human expansion into new environments, recognition of bitter natural toxins through taste may have conferred an important selective advantage. The G protein-coupled receptor encoded by TAS2R16 mediates response to salicin, amygdalin, and many bitter beta-glucopyranosides. beta-glucopyranosides are ubiquitous in nature, with many having a highly toxic cyanogenic activity. RESULTS: We examined evidence for natural selection on the human receptor TAS2R16 by sequencing the entire coding region, as well as part of the 5' and 3' UTRs, in 997 individuals from 60 human populations. We detected signatures of positive selection, indicated by an excess of evolutionarily derived alleles at the nonsynonymous site K172N and two linked sites and significant values of Fay and Wu's H statistics in 19 populations. The estimated age range for the common ancestor of the derived N172 variant is 78,700-791,000 years, placing it in the Middle Pleistocene and before the expansion of early humans out of Africa. Using calcium imaging in cells expressing different receptor variants, we showed that N172 is associated with an increased sensitivity to salicin, arbutin, and five different cyanogenic glycosides. CONCLUSION: We have detected a clear signal of positive selection at the bitter-taste receptor gene TAS2R16. We speculate that the increased sensitivity that is shown toward harmful cyanogenic glycosides and conferred by the N172 allele may have driven the signal of selection at an early stage of human evolution.  (+info)

Amygdalin inhibits genes related to cell cycle in SNU-C4 human colon cancer cells. (7/26)

AIM: The genes were divided into seven categories according to biological function; apoptosis-related, immune response-related, signal transduction-related, cell cycle-related, cell growth-related, stress response-related and transcription-related genes. METHODS: We compared the gene expression profiles of SNU-C4 cells between amygdalin-treated (5 mg/mL, 24 h) and non-treated groups using cDNA microarray analysis. We selected genes downregulated in cDNA microarray and investigated mRNA levels of the genes by RT-PCR. RESULTS: Microarray showed that amygdalin downregulated especially genes belonging to cell cycle category: exonuclease 1 (EXO1), ATP-binding cassette, sub-family F, member 2 (ABCF2), MRE11 meiotic recombination 11 homolog A (MRE11A), topoisomerase (DNA) I (TOP1), and FK506 binding protein 12-rapamycin-associated protein 1 (FRAP1). RT-PCR analysis revealed that mRNA levels of these genes were also decreased by amygdalin treatment in SNU-C4 human colon cancer cells. CONCLUSION: These results suggest that amygdalin have an anticancer effect via downregulation of cell cycle-related genes in SNU-C4 human colon cancer cells, and might be used for therapeutic anticancer drug.  (+info)

Isolation and quantitation of amygdalin in Apricot-kernel and Prunus Tomentosa Thunb. by HPLC with solid-phase extraction. (8/26)

Apricot-kernel and Prunus Tomentosa Thunb. are traditional Chinese herb medicines that contain amygdalin as their major effective ingredient. In this report, three methods for the extraction of amygdalin from the medicinal materials are compared: ultrasonic extraction by methanol, Soxhlet extraction by methanol, and reflux extraction by water. The results show that reflux extraction water containing 0.1% citric acid is the best option. The optimal reflux is 2.5 h and water bath temperature is 60 degrees C. The solid-phase extraction method using C18 and multiwalled carbon nanotube as adsorbents is established the pretreatment of reflux extract, and the result shows that the two adsorbents have greater adsorptive capacity for amygdalin and good separation effect. In order to quantitate amygdalin in Apricot-kernel and Prunus Tomentosa Thunb., a reversed-phase high-performance liquid chromatography method using methanol-water (15:85, for 30 min and pure methanol after 30 min) as mobile phase is developed and a good result is obtained.  (+info)

Amygdalin is a naturally occurring compound found in the seeds of some fruits, such as apricots, and in certain nuts, including almonds. It is also known as "laetrile" and has been promoted as an alternative treatment for cancer. However, its effectiveness as a cancer treatment is not supported by scientific evidence, and it can have serious side effects, including cyanide poisoning. The use of amygdalin as a medical treatment is not approved by regulatory agencies in many countries, including the United States and Canada.

Hydrogen Cyanide (HCN) is a chemical compound with the formula H-C≡N. It is a colorless, extremely poisonous and flammable liquid that has a bitter almond-like odor in its pure form. However, not everyone can detect its odor, as some people lack the ability to smell it, which makes it even more dangerous. It is soluble in water and alcohol, and its aqueous solution is called hydrocyanic acid or prussic acid.

Hydrogen Cyanide is rapidly absorbed by inhalation, ingestion, or skin contact, and it inhibits the enzyme cytochrome c oxidase, which is essential for cellular respiration. This leads to rapid death due to hypoxia (lack of oxygen) at the cellular level. It is used industrially in large quantities as a pesticide, fumigant, and chemical intermediate, but it also has significant potential for use as a chemical weapon.

In the medical field, Hydrogen Cyanide poisoning can be treated with high-concentration oxygen, sodium nitrite, and sodium thiosulfate, which help to restore the function of cytochrome c oxidase and enhance the elimination of cyanide from the body.

"Prunus" is a term that refers to a genus of plants, which includes many familiar fruits such as plums, cherries, peaches, and almonds. It's not a medical term, but rather a botanical one. The fruit of these plants are often used in food medicine due to their nutritional value and health benefits. For example, prunes (dried plums) are known for their laxative effects. However, the plant itself or its extracts can also have medicinal uses, mainly as anti-inflammatory, antioxidant and cardioprotective agents.

In a medical context, "nuts" are typically referred to as a type of food that comes from dry fruits with one seed in them. They are often high in healthy fats, fiber, protein, and various essential nutrients. Examples include almonds, walnuts, hazelnuts, cashews, pistachios, and pecans. However, it's important to note that some people may have allergies to certain types of nuts, which can cause serious health problems.

Beta-glucosidase is an enzyme that breaks down certain types of complex sugars, specifically those that contain a beta-glycosidic bond. This enzyme is found in various organisms, including humans, and plays a role in the digestion of some carbohydrates, such as cellulose and other plant-based materials.

In the human body, beta-glucosidase is produced by the lysosomes, which are membrane-bound organelles found within cells that help break down and recycle various biological molecules. Beta-glucosidase is involved in the breakdown of glycolipids and gangliosides, which are complex lipids that contain sugar molecules.

Deficiencies in beta-glucosidase activity can lead to certain genetic disorders, such as Gaucher disease, in which there is an accumulation of glucocerebrosidase, a type of glycolipid, within the lysosomes. This can result in various symptoms, including enlargement of the liver and spleen, anemia, and bone pain.

  • Amygdalin (from Ancient Greek: ἀμυγδαλή amygdalē 'almond') is a naturally occurring chemical compound found in many plants, most notably in the seeds (kernels) of apricots, bitter almonds, apples, peaches, cherries and plums, and in the roots of manioc. (wikipedia.org)
  • Although the synthesized version of amygdalin is the (R)-epimer, the stereogenic center attached to the nitrile and phenyl groups easily epimerizes if the manufacturer does not store the compound correctly. (wikipedia.org)
  • For one method of isolating amygdalin, the stones are removed from the fruit and cracked to obtain the kernels, which are dried in the sun or in ovens. (wikipedia.org)
  • Within these plants, amygdalin and the enzymes necessary to hydrolyze it are stored in separate locations, and only mix as a result of tissue damage. (wikipedia.org)
  • Amygdalin is a glycoside initially isolated from the seeds of the tree Prunus dulcis, also known as bitter almonds. (labcloudinc.com)
  • Amygdalin is hydrolyzed by intestinal β-glucosidase (emulsin) and amygdalin beta-glucosidase (amygdalase) to give gentiobiose and L-mandelonitrile. (wikipedia.org)
  • Benzaldehyde released from amygdalin provides a bitter flavor. (wikipedia.org)
  • Because of a difference in a recessive gene called Sweet kernal [Sk], much less amygdalin is present in nonbitter (or sweet) almond than bitter almond. (wikipedia.org)
  • And Dr. Dean Burk, Laetrile's chief defender within the otherwise hostile National Cancer Institute, told me: 'Both Dr. [Hans] Nieper and I have conceived of several mechanisms of action of amygdalin which have nothing to do with any action of cyanide. (whale.to)

  • Amygdalin-- A naturally occurring cyanogenic glucoside found in almonds and apricot pits. (cdc.gov)
  • Laetrile is the name for a semi-synthetic compound which is chemically related to amygdalin, a cyanogenic glycoside from the kernels of apricots and various other species of the genus Prunus . (cochrane.org)
  • Laetrile is a word created from the first letters of laevorotatory and mandelonitrile and describes a semi-synthetic form of amygdalin. (cochrane.org)
  • Both laetrile and amygdalin have a common structural component, mandelonitrile, that contains cyanide. (cochrane.org)
  • However, it is possible to buy laetrile or amygdalin via the Internet. (cochrane.org)
  • Cancer patients should be informed about the high risk of developing serious adverse effects due to cyanide poisoning after laetrile or amygdalin, especially after oral ingestion. (cochrane.org)
  • This systematic review found that there is no reliable evidence for the alleged effects of laetrile or amygdalin for curative effects in cancer patients. (cochrane.org)
  • The claims that laetrile or amygdalin have beneficial effects for cancer patients are not currently supported by sound clinical data. (cochrane.org)
  • There is a considerable risk of serious adverse effects from cyanide poisoning after laetrile or amygdalin, especially after oral ingestion. (cochrane.org)
  • The risk-benefit balance of laetrile or amygdalin as a treatment for cancer is therefore unambiguously negative. (cochrane.org)
  • Laetrile and amygdalin are promoted under various names for the treatment of cancer although there is no evidence for its efficacy. (cochrane.org)
  • To assess the alleged anti-cancer effect and possible adverse effects of laetrile and amygdalin. (cochrane.org)
  • We searched eight databases and two registers for studies testing laetrile or amygdalin for the treatment of cancer. (cochrane.org)
  • Another product of apricot kernel oil, amygdalin, may be a cancer cell blocker, according to the the National Cancer Institute. (massage-education.com)
  • Although no specific mention has been seen for this species, all members of the genus contain amygdalin and prunasin, substances which break down in water to form hydrocyanic acid (cyanide or prussic acid). (pfaf.org)
  • The seeds of apples, also known as "pips", contain a sugar/cyanide compound called "amygdalin", which turns into hydrogen cyanide when it is metabolized in your body. (todayifoundout.com)
  • Apple seeds contain amygdalin, which when chewed up and digested can convert to low levels of cyanide. (eatthis.com)
  • Cherry kernels, found inside the pits, contain a poisonous compound called amygdalin, which can cause sickness if consumed. (sciencekids.co.nz)
  • However, whether amygdalin acts on drug-resistant tumor cells remains questionable. (uni-frankfurt.de)
  • An in vitro study was performed to investigate the influence of amygdalin (10 mg/mL) on the growth of a panel of therapy-naïve and docetaxel- or cabazitaxel-resistant PCa cell lines (PC3, DU145, and LNCaP cells). (uni-frankfurt.de)
  • Amygdalin may, therefore, block tumor growth and disseminative characteristics of taxane-resistant PCa cells. (uni-frankfurt.de)
  • Previous studies indicated antitumoral properties of the natural compound amygdalin. (uni-frankfurt.de)
