Maltotetraose [34612-38-9]

Référence HY-N2464-25mg

Conditionnement : 25mg

Marque : MedChemExpress


Description

Maltotetraose can serve as a substrate for enzyme-linked assays to measure amylase activity in biological fluids. Maltotetraose has oral active, and reduces TNF-α-induced inflammatory responses by inhibiting NF-κB activity and decreasing ICAM-1 expression. Maltotetraose also inhibits PDGF-induced vascular smooth muscle cell migration and neovascularization. Additionally, Maltotetraose derivatives can function as probes for detecting bacterial infections by targeting the maltodextrin transporter. With good long-term safety, Maltotetraose holds promise for research in atherosclerosis-related diseases[1][2][3][4].

IC50 & Target

Human Endogenous Metabolite

 

In Vitro

Maltotetraose (20-40 μM, 30 min) suppresses NF-κB activation and ICAM-1 expression, potentially aiding in the early prevention of atherosclerosis[2].
Maltotetraose (20 μM, 30 min) inhibits PDGF-induced vascular smooth muscle cell migration, suggesting a potential role in atherosclerosis prevention[2].

Western Blot Analysis[2]

Cell Line: MOVAS-1 mouse vascular smooth muscle cells
Concentration: 20-40 μM
Incubation Time: 30 min (Cells were pretreated with Maltotetraose (20-40 μM) for 30 minutes, followed by TNF-α (10 ng/mL) stimulation for 3-8 hours)
Result: Inhibited the phosphorylation of NF-κB-related protein.

RT-PCR[2]

Cell Line: MOVAS-1 mouse vascular smooth muscle cells
Concentration: 20-40 μM
Incubation Time: 30 min (Cells were pretreated with Maltotetraose (20-40 μM) for 30 minutes, followed by TNF-α (10 ng/mL) stimulation for 3-8 hours)
Result: Significantly decreased ICAM-1 mRNA levels.

Cell Migration Assay [2]

Cell Line: MOVAS-1 mouse vascular smooth muscle cells
Concentration: 20 μM
Incubation Time: 30 min (Cells were pretreated with Maltotetraose (20 μM) for 30 minutes, followed by PDGF (20 ng/mL) stimulation for 6-7 days)
Result: Significantly inhibited PDGF-induced vascular smooth muscle cell migration and new blood vessel formation in aortic ring explants.
In Vivo

Maltotetraose (10% in diet or 5,000 mg/kg via p.o., once daily for 90 days) dose not induce significant toxicity, suggesting good long-term safety[1].

Animal Model: Wistar rats[3]
Dosage: Dietary group: 10% (equivalent to 6,818 mg/kg/day in males, 7,464 mg/kg/day in females); Gavage group: 1,000, 3,000, or 5,000 mg/kg/day
Administration: Dietary intake or oral gavage (p.o.), Once daily for 90 consecutive days
Result: Sid not cause mortality or severe adverse effects in rats over 90 days.
Reduced food intake but no significant body weight differences (The 5,000 mg/kg/day gavage group).
