    Biological Activity
    Description: Danthron is an organic substance. It used to be a laxatica and now is currently used as an antioxidant in synthetic lubricants, in the synthesis of experimental antitumor agents, as a fungicide and as an intermediate for making dyes.Dantron can cause a significant reduction in the growth rate of Earthworms, it has potentially dangerous to the soil ecosystem.

    Factors influencing constipation in advanced cancer patients: a prospective study of opioid dose, dantron dose and physical functioning.[Pubmed: 12882260]

    METHODS AND RESULTS:
    The relationship between opioid dose, Dantron dose, bowel function and physical functioning (measured with the modified Barthel Index) was determined in a sample of 50 inpatients with advanced cancer. Data were collected prospectively from chart review and patient interviews one week after admission to allow for protocol-driven management of constipation to be established. Bowel scores were significantly reduced in 35 patients treated with opioids compared with 15 patients not treated with opioids. Within the opioid group, however, there was no relationship between opioid dose, bowel score, Dantron dose or Barthel Index. Higher doses of Dantron were associated with better physical functioning (but not opioid dose) suggesting that for any given dose of opioid, fitter patients were treated with larger doses of laxatives.
    CONCLUSIONS:
    Factors other than opioid dose and physical functioning may be more important in contributing to constipation in this group of patients. Less potent opioid drugs, such as codeine, are just as likely to cause constipation as more potent opioids.

    Cleansing of the colon without enemas.[Pubmed: 1215526]
    Several methods have been used to cleanse the large bowel prior to roentgen examination and rectoscopy for more than ten years.
    METHODS AND RESULTS:
    A method with administration of a salt solution (SALAX) in combination with different oral laxatives (Cascara sagrada, Dantron, Bisacodyl) without cleansing enemas is described. Hospitalized patients should have an individual preparation while ambulatory patients are almost completely cleansed if they carefully follow the given instructions.

    Adverse effects of drugs used in the management of constipation and diarrhoea.[Pubmed: 8136086]
    Most laxatives, if used intermittently in the absence of contraindications, are relatively safe. Bulking agents may diminish absorption of some minerals and drugs, but this is not usually clinically significant. Ispaghula can cause serious allergic reactions. The chronic ingestion of stimulant laxatives has been blamed for the development of the 'cathartic colon', but there are no definitive studies which have demonstrated this.
    METHODS AND RESULTS:
    Dantron (danthron) preparations should only be used in older patients and the terminally ill because of the risk of hepatotoxicity with this drug. Oral oxyphenisatine should no longer be used. Senna would appear to be the stimulant laxative of choice during pregnancy and lactation. Bisacodyl is the polyphenolic derivative of choice. Lactulose, sorbitol and lactilol rarely cause significant adverse effects. Magnesium salt laxatives and phosphate enemas can cause serious metabolic disturbances in babies and young children. Liquid paraffin is contraindicated if there is any risk of aspiration. Interference with the absorption of fat soluble vitamins would not appear to be clinically significant. Docusate sodium may potentiate the hepatotoxicity of other drugs, but reports of this are rare. The role of cisapride in constipation has not been established. Antidiarrhoeal drugs are second line drugs whose use is aimed at minimising inconvenience and discomfort. No antidiarrhoeals can be recommended for children under 4 years of age. Loperamide is the drug of choice in older children and adults. The atropine component of diphenoxylate/atropine combinations can cause significant adverse effects. Bismuth salicylate is an inconvenient treatment for travellers' diarrhoea as large frequent doses of the liquid formulation are needed. Some bismuth can be absorbed and there is the potential to cause encephalopathy. Octreotide, methysergide and cholestyramine have a role for specific causes of diarrhoea only.
    CONCLUSIONS:
    Octreotide is effective in high output states from the small or large bowel, with few adverse effects. Clonidine and lidamidine may have a role in the treatment of chronic diabetic diarrhoea. The role of lidamidine in nondiabetic chronic diarrhoea has not been established.

    Source: The roots of Rheum palmatum.
    Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
    Storage: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

    Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

    Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

    After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

    Effect of 1,8-dihydroxyanthraquinone on body mass and protein content of earthworms[Reference: WebLink]

    METHODS AND RESULTS:
    Effects of 1, 8-dihydroxyanthraquinone(Dantron) on growth rate and protein content of earthworms. No lethal effect of 1, 8-dihydroxyanthraquinone(Dantron) was observed even at the highest concentration(1.0 g/kg soil) of exposure. The sub-lethal effect, however, was evident at all the concentration scale. 1, 8-dihydroxyanthraquinone(Dantron) caused a significant reduction in the growth rate (maximum - 22.5%) at the dosage of 1.0 g/kg and 28 days contact time. Additionally a reduction in total soluble protein was observed in all treated worms(maximum - 39.6%) at the dosage of 0.8 g/kg and 7 days contact time.
    CONCLUSIONS:
    1, 8-dihydroxyanthraquinone (Dantron) was potentially dangerous to the soil ecosystem and more ecological risk assessment of this chemical material should be thoroughly carried out.
