Thiazolidines derivatives and their anti-inflammatory activity in LPS-induced RAW 264.7 macrophages: a systematic...

Thiazolidine scaffolds have been investigated for decades, due to their wide range of biological activity. In this way, the main objective of this systematic review was to elucidate the anti-inflammatory activity of thiazolidine derivatives against nitric oxide (NO) production in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages. From 9718 identified registers, 13 articles were included, where 11 studies evaluated thiazolidinediones. The summary of relevance demonstrated that seven studies (53.8%) were relevant without restrictions, and 6 (46.2%) were relevant with restrictions. The certainty in cumulative evidence was considered moderate and the six studies included in the meta-analysis demonstrated the positive activity of thiazolidinediones against NO production when compared to the negative LPS control.
