General description

Curcumin is a yellow-colored polyphenol obtained from the rhizome of Curcuma longa L. It constitutes an important part of various diets and herbal medicines, especially in the Asian continent for its various salubrious effects on human health.[1][2][3]

Application

Curcumin has been used:
  • to study its effect on the consequences and mechanism involved in the suppression of human homeobox gene NKX3.1 in the prostate cancer cell LNCaP[1]
  • to examine its effect on stress in pigs by having an inhibitory impact on the serum cortisol concentration, hippocampal nitric oxide production, and brain-derived neurotrophic factor expression[2]
  • to study its effect as a dietary supplement on the growth, immunity, antioxidant activity, and disease resistance in Oreochromis niloticus[3]
  • to analyze its protective effect on the organotypic hippocampal slice cultures against the synaptic toxicity caused by amyloid beta peptides (Aβ1–42)[4]
  • to examine the possibility of its non-toxic concentrations to decrease the inflammation caused by interleukin-1beta (IL-1β) in cartilage explant cultures[5]
  • to study its protective impact against intestinal ischemia-reperfusion injury in rats[6]
  • to measure its antibacterial activity in vitro[3]
  • to determine its preventative effects for Alzheimer′s disease (AD) in mice[7]
  • as a bifunctional agent for generation and validation of the erythroid 2-related factor 2 (Nrf2) reporter system[8]
  • to study its in vitro inhibitory effects on human liver glucuronidation activity[9]
  • to evaluate its effects on Parkinson′s disease (PD)-like phenotypes[10]

Biochem/physiol Actions

A natural phenolic compound responsible for the yellow color of turmeric. Potent anti-tumor agent that acts against highly diverse tumor-specific pathways. Anti-inflammatory and anti-oxidant. Induces apoptosis in cancer cells and inhibits phorbol ester-induced protein kinase C (PKC) activity. Reported to inhibit production of inflammatory cytokines by peripheral blood monocytes and alveolar macrophages. Potent inhibitor of EGFR tyrosine kinase and IκB kinase. Inhibits inducible nitric oxide synthase (iNOS), cyclooxygenase (COX-2) and 5-lipoxygenase (5-LOX).
A natural phenolic compound. Potent anti-tumor agent having anti-inflammatory and anti-oxidant properties. Curcumin has been cited as a potential chemopreventive agent, in addition to its chemotherapeutic activity. Induces apoptosis in cancer cells and inhibits phorbol ester-induced protein kinase C (PKC) activity. Reported to inhibit production of inflammatory cytokines by peripheral blood monocytes and alveolar macrophages. Potent inhibitor of EGFR tyrosine kinase and IκB kinase. Inhibits inducible nitric oxide synthase (iNOS), cycloxygenase and lipoxygenase. Easily penetrates into the cytoplasm of cells, accumulating in membranous structures such as plasma membrane, endoplasmic reticulum and nuclear envelope.
Curcumin possesses anti-inflammatory, cancer prophylactic, and anti-oxidant properties. It also exhibits antagonistic nature towards the cluster of colon, breast, and blood marrow cancer. It does so by means of having an inhibitory effect on the various associated enzymes such as cycloxygenase-2 (COX-2), lipoxygenase and ornithine decarboxylase.[1] It is also postulated to have anti-depressant, anti-stress and neuroprotective effects on humans and other animals.[2] It is being proclaimed to be used as a treatment for Alzheimer′s disease due to its ability to cause synaptic toxicity.[4] Additionally, it also shows anti-fungal, antiviral, anti-microbial, chemosensitizing, radiosensitizing, and wound healing activities.[6]

Questions

1–6 of 6 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  5. What are the recommended methods for dissolving curcumin powder (C1386)?

    1 answer
    1. Dissolving curcumin (product C1386) can be challenging. Below are some recommendations for preparing standard solutions:
      • Ethanol: 10mg/mL
      • DMSO: >11 mg/mL (according to available literature)
      • 0.5 M NaOH: Soluble (then immediately dilute in PBS according to literature)
      Additionally, here are two methods that might be helpful:
      Method 1: Use DMSO to create a stock solution at 1000 times the working concentration of curcumin.

  6. Hello, I am currently looking for curcumin powder that I can use as a standard for UV spectrophotometer quantification. What is the difference between the product that is offered here compared to 08511-10 MG Curcumin product?

    1 answer
    1. Both items are research grade products. Product 08511 is assigned a minimum purity specification of 98% and is tested for use as an an analytical standard in HPLC and GC. The C1386 is assigned a minimum purity specification of 65% and is not tested for any specific application. The major differences will lie in the purity and testing for each product. Please see the sample Certificate of Analysis for both items:
