Metabolite Identification
Common NameEthyl pyruvate
DescriptionEthyl pyruvate, also known as pyruvic acid ethyl ester or 2-oxo-propionate ethyl ester, belongs to the family of alpha-keto acids and derivatives. These are organic compounds containing an aldehyde substituted with a keto group on the adjacent carbon. Ethyl pyruvate is soluble (in water) and an extremely weak acidic compound (based on its pKa). When given as a drug, ethyl pyruvate (known as CTI-01) inhibits the systemic release of cytokines (e.g. TNF-alpha and HMGB1), which promote the body's inflammatory response. The over-expression of these cytokines has been linked to diseases that occur in critical care settings, such as severe organ damage following cardiopulmonary bypass (CPB) and post-operative ileus following abdominal surgery (DrugBank). Ethyl pyruvate is a flavouring ingredient.

General function:
Involved in tumor necrosis factor receptor binding
Specific function:
Cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It is mainly secreted by macrophages and can induce cell death of certain tumor cell lines. It is potent pyrogen causing fever by direct action or by stimulation of interleukin-1 secretion and is implicated in the induction of cachexia, Under certain conditions it can stimulate cell proliferation and induce cell differentiation
