In vitro and rat studies suggest synthetic disialyl hexasaccharides could help prevent necrotizing enterocolitis in infants. Human milk oligosaccharides including disialyllacto-N-tetraose (DSLNT) contribute to the gut health of breastfed infants but are difficult to synthesize. In a neonatal rat model of necrotizing enterocolitis, the synthetic disialyl hexasaccharides disialyllacto-N-neotetraose (DSLNnt) and a2-6-linked disialyllacto-N-tetraose (DSʹLNT) protected rats from necrotizing enterocolitis with potency comparable to that of human milk oligosaccharides. Next steps include testing the synthetic hexasaccharides in additional animal models.
