Documented Uses

• Used as a flavoring agent; [FDA]
• Flavouring Agent -> FLAVOURING_AGENT -> JECFA Functional Classes
• Flavoring Agents -> JECFA Flavorings Index
• Propanoic acid, 2-oxo-, ethyl ester: ACTIVE
• Investigated for use/treatment in burns and burn infections, cardiac surgery, inflammatory disorders (unspecified), ischemic reperfusion injury, and sepsis and septicemia.
• CTI-01 inhibits the systemic release of cytokines, such as 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.
