Biochem/physiol Actions

COX-2 catalyzes the conversion of arachidonic acid to prostaglandin H2 (the first step in the biosynthesis of prostaglandins, thromboxanes, and prostacyclins). It is the inducible form of cyclooxygenase, induced by phorbol esters, lipopolysaccharides, and cytokines. COX-2 is upregulated in the neovasculature of malignant tumors. Inhibition of COX-2 with nonsteroidal anti-inflammatory drugs (NSAIDs) is associated with decreased tumor growth.

Other Notes

Tagged with a six-residue histidine sequence near the N-terminus.

Unit Definition

Background. The current study aims to give a scientific origin for employing Habenaria plantaginea Lindl. as a potential candidate against nociception, inflammation, and pyrexia. The pharmacological studies were performed on crude extract and subfractions. In the gas chromatography-mass spectroscopy analysis

In recent years, drug discovery paradigm has been shifted from conventional single target inhibition toward multitarget design concept. In current research, we have reported synthesis, in-vitro, in-vivo and acute toxicity determination of N-substituted pyrrolidine-2,5-dione derivatives as multitarget anti-inflammatory agents. We
