Kinin

A kinin is any of various structurally related polypeptides, such as bradykinin and kallikrein.[1] They are members of the autacoid family.[2]

They act locally to induce vasodilation and contraction of smooth muscle.[3][4]

It is a component of the kinin-kallikrein system.

Their precursors are kininogens.[5]

In botany, plant hormones cytokinins were first called kinins, but the name was changed to avoid confusion.[6]

Aspirin inhibits the activation of kallenogen by interfering with the formation of kallikrien enzyme which is essential in the process of activation.
