What are peptide autacoids?

Polypeptides are endogenous agents, involved in the regulation of many physiologic functions and the pathogenesis of several diseases. Polypeptide antagonists form a group of new chemical entities which may provide valid therapeutic agents.

What are autacoids with example?

These are local hormones; they therefore have a paracrine effect. Some notable autacoids are: eicosanoids, angiotensin, neurotensin, NO (nitric oxide), kinins, histamine, serotonin, endothelins and palmitoylethanolamide.

Which drug is amine autacoids?

Histamine and serotonin (5-hydroxytryptamine) are two important amine autacoids. Other autacoids, which produce paracrine type effects, include polypeptides (angiotensin, bradykinin, and kallidin), lipid-derived substances (prostaglandins, leukotrienes, and platelet-activating factor), and nitric oxide.

Is the autacoids good for our body?

Autacoids play a key role in allergy, inflammation, smooth muscle function, pain, and certain types of drug reactions (Anaphylaxis).

How are autacoids used in pharmacology presentation?

Which is the best description of an autacoid?

Where are peptide autacoids found in animal tissues?

Peptide autacoids – Plasma kinins (Bradykinin, Kallidin), Angiotensinogen Lipid autacoids – Prostaglandins, Leukotrienes, PAF Histamine – Introduction Meaning “tissue amine” (histos– tissue) – abundantly present in animal tissues – also in plants like “stinging nettle” Mediator of hypersensitivity and tissue injury reaction– Physiological role
