General description

Nikotin ist das in den Blättern der Nicotiana-Spezies am häufigsten vorkommende Alkaloid. Es ist ein wichtiger toxischer Wirkstoff.

Application

(-)-Nikotin wird verwendet:
  • zur Stimulierung von Neutrophilen im extrazellulären DNA-Fluoreszenztest und bei der Immunfärbung von Neutrophilen
  • zur Untersuchung der Auswirkungen der chronischen Nikotinexposition von Neugeborenen auf die Nikotin-Acetylcholinrezeptor(nAChR)-Bindung, den Zelltod und die Morphologie im Hippocampus und Kleinhirn
  • in einer In-vitro-Studie zur Bewertung der Wirkung einer Wurzelexposition gegenüber Nikotin oder Cotinin auf die Morphologie und Dichte von Fibroblasten

Biochem/physiol Actions

Prototyp Nikotin-Acetylcholin-Rezeptor-Agonist; natürlich vorkommendes Isomer.
Nikotin bindet an nikotinische Acetylcholinrezeptoren und zeigt sowohl neuroprotektive als auch neurotoxische Wirkungen auf das sich entwickelnde Gehirn. Es wird mit der Entwicklung von Lungenkrebs in Verbindung gebracht und verringert die Wirksamkeit von Chemotherapeutika. Darüber hinaus kann Nikotin die phagozytäre Wirtsabwehr beeinträchtigen und zu vermehrten, mit reaktiven Sauerstoffspezies (ROS) verbundenen Verletzungen führen. Es stoppt zudem die Deaktivierung der Akt/Proteinkinase B (PKB) und verringert den spontanen Tod von Neutrophilen. Nikotin wird zur Behandlung von Alzheimer und Parkinson eingesetzt.

Preparation Note

Dieses Produkt sollte in reinem Ethanol (200 Proof) aufgelöst werden.

Questions

1–10 of 12 Questions  
  1. Is that product soluble in DMSO?

    1 answer
    1. This product has not been tested for solubility in DMSO. However, product 612030 is a Nicotine solution prepared at 2 mg/mL in DMSO. In addition, external sources indicate that this material is soluble up to 30 mg/mL in DMSO. Other solvents include Methanol, Ethanol, Dimethylformamide, and Chloroform.

  2. Is product N3876 (-)-Nicotine considered freebase nicotine or a nicotine salt dissolved in a carrier liquid

    1 answer
    1. This product is nicotine free base and is provided in the form of a neat or pure liquid.

      Helpful?

  3. Hi , How i want to measure the purity level of nicotine? Can refractive index or polarimeter use to measure level of impurity?

    1 answer
    1. The measurement of purity in nicotine can be assessed using various analytical techniques. Refractive index and polarimetry are among the methods that can provide useful information. However, it's important to note that these techniques may not directly measure specific impurities but can be indicative of changes in the overall composition or characteristics of a substance. The purity of this product is determined by GC. Gas Chromatography (GC) is a widely used and effective method for assessing the purity of nicotine and detecting impurities. GC separates and analyzes components based on their volatility and interaction with a stationary phase.

  4. Hello, I would like to know the concentration of the nicotine in this liquid solution.

    1 answer
    1. This product is a neat or pure liquid. Based on the density of 1.02 g/mL and the molecular weight of 162.2 g/mole, the calculated molar concentration is 6.3 M.

  5. How long is the nicotine stable if stored at room temperature? How long is it stable after being dssiolved and how should the solution be stored?

    1 answer
    1. This compound is stored at room temperature, but is extremely sensitive to light, moisture, and oxygen. The product is a neat liquid and packaged in amber glass under argon to preserve stability. In the unopened container, the product is stable at least until the recommended retest date reported on the lot specific Certificate of Analysis. This date is typically 3 years from the quality release date. Factors such as light, humidity, and exposure to air will limit the shelf life after opening, It is recommended to prepare solutions fresh. The vial head space should be cleared with argon or nitrogen prior to closing. Increased darkening of the material is an indication of product degradation.

  7. What is the molarity of Product N3876,  (-)-Nicotine?

    1 answer
    1. The molarity of (-)-Nicotine is 6.23 M based on a 100% pure compound with a density at 20 °C equal to 1.010 g/mL.  If you multiply this density by 1000, you obtain g/L.  If you divide g/L by the molecular weight of (-)-Nicotine which is 162.2 g/mole, you get moles per L which is molarity.  [1.010 x 1000]/162.2 = 6.23 M.
