MONOCROTALINE Usage And Synthesis
  • DescriptionMonocrotaline (MCT) is a toxic 11-membered macrocyclic pyrrolizidine alkaloid (PA) derived from the seeds of the Crotalaria spectabilis plant. It poisons livestock and humans through the ingestion of contaminated grains and other foods. Pyrrolizidine alkaloid is activated by cytochrome P450 to the reactive pyrrole metabolite dehydromonocrotaline (MCTP) in the liver. The alkaloid causes pulmonary artery hypertension, right ventricular hypertrophy, and pathological changes in the pulmonary vasculature.
    Monocrotaline is produced for research use. It is used in rat model to investigate human pulmonary hypertension as it offers technical simplicity, reproducibility, and low cost compared with other models of pulmonary hypertension.

  • Chemical PropertiesWhite to light tan powder
  • UsesA toxic pyrrolizidine alkaloid isolated from Crotalaria spp. It is used for inducing pulmonary diseases in rats.
  • Usesantineoplastic, insect sterilant
  • Safety ProfileSuspected carcinogen with experimental carcinogenic data. Poison by ingestion, intravenous, intraperitoneal, and subcutaneous routes. Human mutation data reported. When heated to decomposition it emits toxic fumes of NOx.
  • Purification MethodsCrotaline forms prisms from absolute EtOH and recrystallises also from CHCl3. UV in 96% EtOH has max 217nm (log  3.32). [Adams et al. J Am Chem Soc 74 5612 1952, Culvenor & Smith Aust J Chem 10 474 1957.] The hydrochloride has m 212-214o (from MeOH/Et2O) and [] D28 -38.4o (c 5, H2O) [Adams & Gianturco J Am Chem Soc 78 1922 1956]. The picrate has m 230-231.5o(dec) [Adams et al. J Am Chem Soc 74 5614 1952]. [Beilstein 27 III/IV 6660.]
