Leukotriene B4-d₄  (Synonyms: LTB4-d₄; 5(S),12(R)-DiHETE-d₄)

Leukotriene B4-d₄ is the deuterium labeled Leukotriene B4. Leukotriene B4 (LTB4) is known as one of the most potent chemoattractants and activators of leukocytes and is involved in inflammatory diseases. Leukotriene B4 is also an alkyl chain-based PROTAC linker that can be used in the synthesis of PROTACs[1][2][3].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
