Alkaloid Peptides

Alkaloid peptides are a group of naturally occurring chemical compounds containing mostly basic nitrogen atoms. Alkaloids peptides are generated by organisms such as bacteria, fungi, plants and animals as well. Most alkaloids can be extracted and purified by acid-base extraction. And many alkaloids peptides are toxic to other organisms. Alkaloids peptides often have pharmacological effects and can be used as medications and recreational drug or in entheogenic rituals. Typical examples of peptide alkaloid are: ergotamine, pandamine, dynorphin A-(1-8)-octapeptide, N beta-(D-Leu-D-Arg-D-Arg-D-Leu-D-Phe)-naltrexamine, etc. The applications of alkaloids peptides have covered the medical and agricultural fields. Alkaloids peptides play roles in a diversity of metabolic systems in humans and other animals.
