Inflammation refers to a commonly used broad term for a local response to cellular injury characterized by pain, capillary dilatation, odema, heat, redness and loss of function. To date, a number of hydrazone derivatives has been efficiently synthesized and evaluated for the analgesic and anti-inflammatory activities. It is important to mention that COX-I and COX-II have an important role in the inflammation. Structure modification of the parent bioactive molecule which is a common practice over the years may further enhance its biological importance.
