spartein

spartein

A scientist carefully measures spartein in the laboratory.

Definition
  1. Noun:
    • A chemical compound: "spartein" is a naturally occurring alkaloid, specifically a lupin alkaloid, found in various plants of the genus Lupinus (lupines). It is a bicyclic quinolizidine alkaloid with the molecular formula C₁₅H₂₆N₂.
    • Pharmacological agent: "spartein" has been used historically as a cardiac antiarrhythmic agent (a class Ia antiarrhythmic drug) and as an oxytocic agent (a drug that stimulates uterine contractions during childbirth). It also acts as a ganglionic blocking agent.
Usage Examples

  • Noun (chemistry):

    • The chemists isolated spartein from the seeds of the lupine plant. (The researchers extracted the natural alkaloid from plant material.)
    • Spartein is a key compound in the study of quinolizidine alkaloids. (It is a central molecule in this chemical class.)

  • Noun (pharmacology):

    • Doctors once prescribed spartein to treat certain heart rhythm disorders. (It was used as a medication for cardiac arrhythmias.)
    • The use of spartein as an oxytocic agent declined due to safety concerns. (It was formerly given to induce labor but is now rarely used.)
Advanced Usage

  • "spartein sulfate": a specific salt form of spartein used in pharmaceutical preparations.

    • The patient was administered spartein sulfate intravenously. (A solution containing this alkaloid was given through a vein.)

  • "spartein-induced arrhythmia": a side effect or experimental condition caused by the drug.

    • In animal studies, spartein-induced arrhythmia was observed at high doses. (The alkaloid caused irregular heartbeats at excessive concentrations.)
Variants and Related Words

  • Sparteine (alternative spelling): a less common variant of the same spelling.

    • The chemical literature occasionally uses sparteine instead of spartein. (Both forms are accepted.)

  • Lupanine (n): a related lupin alkaloid structurally similar to spartein.

    • Lupanine is another alkaloid found alongside spartein in lupine species. (They are chemically related compounds.)
Synonyms

  • Lupin alkaloid: a broad class of alkaloids from lupine plants.

    • Spartein is a type of lupin alkaloid. (It belongs to this group.)

  • Quinolizidine alkaloid: a chemical class characterized by a quinolizidine ring system.

    • Spartein is a quinolizidine alkaloid. (Its structure fits this category.)
