Palm-Derived Tocotrienols as Ferroptosis Modulators in Ischemia–Reperfusion Injury: Linking Phospholipid Peroxidation to Multi- Organ Protection—A Review
Ischemia–reperfusion injury (IRI) is an important determinant of tissue loss following restoration
of blood flow in ischemic stroke, myocardial infarction, acute kidney injury, organ transplantation,
hepatic surgery, intestinal ischemia, and pulmonary transplantation. Ferroptosis has emerged as a
mechanistically important component of IRI because reperfusion simultaneously increases reactive
oxygen species, redox-active iron, mitochondrial stress, and oxidation of polyunsaturated membrane
phospholipids while weakening endogenous antioxidant defenses. Palm-derived tocotrienols are
compelling candidates for intervention because their membrane-associated antioxidant chemistry is
accompanied by effects on inflammation, mitochondrial function, lipid metabolism, and redox signaling.
Recent experimental evidence further demonstrates that tocotrienols can directly suppress ferroptosis
more effectively than corresponding tocopherols in pharmacological and genetic models. This qualitative
literature review integrates contemporary evidence on ferroptosis across cerebral, myocardial, renal,
hepatic, intestinal, and pulmonary IRI with current tocotrienol biology. The synthesis supports a dual-
layer hypothesis whereby tocotrienols may directly terminate phospholipid radical propagation while
indirectly strengthening cellular antiferroptotic resilience. Nevertheless, direct evidence involving
standardized palm tocotrienol-rich fractions in organ-specific IRI remains limited, and human proof-of-
mechanism studies are absent. Future work should differentiate tocotrienol isoforms, employ validated
ferroptosis endpoints, define post-ischemic therapeutic windows, establish tissue pharmacokinetics, and
test compatibility with contemporary reperfusion therapies.
