prostanoid

This term serves as a broad chemical classification in biochemistry and pharmacology. It encompasses several distinct lipid mediators, most notably prostaglandins, thromboxanes, and prostacyclin, which are synthesized from arachidonic acid via the cyclooxygenase pathway.

In a clinical or research context, the word is used to describe the general class of these signaling molecules rather than a specific individual compound. It is typically employed in technical literature regarding inflammation, blood clotting, and smooth muscle contraction.
