Definitions
- the present invention relates to the use of a novel class of imidazole derivatives and pharmaceutical compositions thereof for the treatment of cyclooxygenase-related diseases.

- Metabolites of arachidonic acid are involved in many acute and chronic inflammatory processes. This large class of fatty arachidonic acid metabolites is obtained by a series of enzymes.
- One of the most important enzymes in the sense of treatment is the prostaglandin G/H synthetase, cyclooxygenase (COX). It catalyzes the production of many angiotensin and inflammatory substances such as prostaglandins (PGE 2 , PGD 2 , PGF 2 ), cyclic prostaglandins (PGI 2 ), and thromboxane (TXA 2 ).
- Non-anti-inflammatory drugs have been widely used to treat pain and arthritis due to their significant activity in anti-inflammatory and analgesic.
