More About COX
Cyclooxygenases (officially: prostaglandin G/H synthase, COX; EC 1.14.99.1) catalyze the first two steps in the biosynthesis of prostaglandins (PGs), being the bis-dioxygenation and subsequent reduction of arachidonic acid (AA) to PGG2 and PGH2. The two known isoforms (COX-1 and -2) are the targets of the widely used nonsteroidal anti-inflammatory drugs, indicating a role for these enzymes in pain, fever, inflammation, and tumorigenesis[1]. Due to substrate similarities, inhibitors of this class of enzymes have a lot in common with inhibitors of some desaturase enzymes (e.g. SCD1 and FADS2; EC 1.14.19.1).
