Metabolite of Species Details
Scutellaria baicalensis (NCBI:txid65409) Found in root (BTO:0001188). See: PubMed
Roles Classification
Biological Role(s): EC (prolyl oligopeptidase) inhibitor
Any EC 3.4.21.* (serine endopeptidase) inhibitor that interferes with the action of prolyl oligopeptidase (EC
plant metabolite
Any eukaryotic metabolite produced during a metabolic reaction in plants, the kingdom that include flowering plants, conifers and other gymnosperms.
Application(s): non-steroidal anti-inflammatory drug
An anti-inflammatory drug that is not a steroid. In addition to anti-inflammatory actions, non-steroidal anti-inflammatory drugs have analgesic, antipyretic, and platelet-inhibitory actions. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins.
A compound that, on administration, must undergo chemical conversion by metabolic processes before becoming the pharmacologically active drug for which it is a prodrug.
