Salcaprozate-d₄ sodium  (Synonyms: SNAC-d₄ sodium)

Salcaprozate-d4 (sodium) is a deuterated labeled Salcaprozate (sodium)^[1]. Salcaprozate sodium (SNAC), an oral absorption promoter, and has the potential as a delivery agent for oral forms of heparin and insulin. Salcaprozate sodium could increase passive transcellular permeation across small intestinal epithelia based on increased lipophilicity arising from non-covalent macromolecule complexation^[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].
SNAC (12.5-400 μg/mL; 24 h) has no toxicity to Caco-2 cells, and the survival percentage is above 90% when SNAC is 200 μg/mL^[4].
SNAC (50 and 200 μg/mL) improves the apparent permeability coeffcient (Papp) of RA and SA-B by 2.14-fold and 3.68-fold compared with the Papp of SAs solution^[4].

SNAC improves the oral absorption of both R1 and SAs and enhances bioavailability in rats^[4].
SNAC (2000 mg/kg/d; oral gavage for 13 weeks) related mortality is evident only at the 2000-mg/kg/d level, 20% among males and 50% among females; no clear cause of death is evident^[2].
SNAC (100-1000 mg/kg/d; oral gavage for 13 weeks) induces no mortality in the Wistar rat study at doses up to 1000 mg/kg/d^[2].
