Use of Lacto-N-tetraose

Lacto-N-tetraose is the significant core structure of human milk oligosaccharides (HMOs) naturally existing in human milk. Lacto-N-tetraose is consist of galactose, N-acetylglucosamine, and glucose moieties. Lacto-N-tetraose has prebiotic effect, immune regulatory effect, anti-inflammatory effects, intestinal cell responses regulatory effect, antibacterial activity and antiviral activity. Lacto-N-tetraose has been widely added to infant formula[1].

In Vitro	HMOs exhibits antimicrobial and antibiofilm activity against Streptococcus agalactiae, antibiofilm activity against Methicillin-resistant Staphylococcus aureus (MRSA), and antimicrobial activity against both Acinetobacter baumannii and Clostridium difficile[2]. Lacto-N-tetraose (500-2000 μg/mL) does not cause clastogenic or aneugenic signs in human peripheral blood lymphocytes, nor increase the percentage of micronucleated cells[3].
In Vivo	Lacto-N-tetraose (1000-4000 mg/kg; p.o.; daily for 90 days) does not show toxicity in neonatal SD rats[3]. Animal Model: Female neonatal SD rats (housed together with dam until weaning after 21 days)[3] Dosage: 1000, 25000 and 4000 mg/kg  Administration: p.o.; daily for 90 days Result: Did not show toxicity on clinical observations, body weight, food consumption, development and maturation, clinical pathology, organ weights or histopathology.
