Arachidonic acids
Explanation:
 Non-steroidal anti-inflammatory drugs (NSAIDs) are drugs used due to their analgesic, anti-inflammatory effects.
It inhibit cyclooxygenase (COX) enzyme that takes part in the biosynthesis of prostaglandins (PGs) and thromboxane (TX) and the production of eicosanoids.
Eicosanoids are made by the enzymatic or non-enzymatic oxidation of arachidonic acid or from other polyunsaturated fatty acids (PUFAs) that are close to arachidonic acid which are 20 carbon units in length. 
They are important cell signaling molecules that inhibit inflammation, allergy, fever,regulate abortion of pregnancy and normal childbirth, regulating cell growth.
