Optimized Methods for In Vitro and In Vivo Anti-Inflammatory Assays and Its Applications in Herbal and Synthetic Drug Analysis

Abstract

Inflammatory diseases including, different types of rheumatic diseases are the major problems associated with the presently available non-steroidal anti-inflammatory agents. The numbers of plant derived drugs have been screened for their anti-inflammatory and anti-arthritic activity. Drug development in the recent times often relies on use of natural and synthetic drugs, which are promising candidates as therapeutic agents for prevention of diseases and disorders. These drugs possess different chemical structures, with wide range of therapeutic activities. The mechanism of Inflammation mainly involve in development of serious diseases, such as cancer, rheumatoid arthritis, sprains, bronchitis, muscle pains, chronic inflammatory bowel disease, persistent asthma, and liver fibrosis. Development of inflammatory events basically related to various chemicals, such as glucocorticoids (GCs) and mometasone furoate (MF); endogenous factors such as tumor necrosis factor alpha (TNF-α); enzymes and proteins such as copper and zinc-superoxide dismutase (SOD), proinflammatory peptide substance (PPS), RGD peptides, interleukin-4 (IL-4), IL-10, interferon-γ (IFN-γ), COX, LOX, cytokines such as interleukin-1 (IL-1); reactive oxygen species (ROS), nitric oxide (NO) and prostaglandin E2; as well as pro-inflammatory cells such as T and NK cells are well known to have an important role. Based on these correlations, numerous assays were used for inflammatory mechanism research, which was described in this paper.
