Maltotetraose 可以作为生物流体中酶联测定淀粉酶活性的一个底物。Maltotetraose 具有口服活性,通过抑制 NF-κB 活性和减少 ICAM-1 表达来降低 TNF-α 诱导的炎症反应。Maltotetraose 还能抑制 PDGF 诱导的血管平滑肌细胞迁移和新生血管形成。此外,Maltotetraose 衍生物 可作为探针,通过靶向细菌麦芽糊精转运蛋白 (maltodextrin transporter) 以检测细菌感染。Maltotetraose 具有良好的长期安全性,有望用于动脉硬化相关疾病研究。

生物活性

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].

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)

Maltotetraose (饮食摄入 (饲料中占比 10%) 或灌胃 (5,000 mg/kg),每日一次,持续 90 天) 未引起显著毒性,表明其具有良好的长期安全性[1]

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

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

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
