chitosan oligosaccharide

Chitosan oligosaccharide (COS) 是 β-(1→4)-连接的 D-氨基葡萄糖的寡聚体，Chitosan oligosaccharide可激活 AMPK ，抑制NF-κB 和 MAPK在内的炎症信号通路。

Chitoheptaose heptahydrochloride is a chitosan oligosaccharide with antioxidant, anti-inflammatory, antiapoptotic, and cardioprotective properties. It effectively promotes the growth and photosynthesis parameters of wheat seedlings[1][2].

Chitohexaose hexahydrochloride is a chitosan oligosaccharide compound that possesses anti-inflammatory properties. It exerts its anti-inflammatory effect by binding to the active sites of TLR4, thereby inhibiting inflammation induced by LPS. This compound has been supported by references [1] and [2].

Chitobiose dihydrochloride is a chitosan oligosaccharide consisting of β-1,4-linked glucosamine units.

Chitopentaose pentahydrochloride is an anti-inflammatory chitosan oligosaccharide that functions as a substrate for the gene encoding chitinase B (FjchiB).

Chitobiose为壳寡糖，为β-1,4-氨基葡萄糖二聚体，具备口服活性及较高的抗氧化活性。

Chitotriose，一种可从蟹壳中提取的低聚壳聚糖，具有针对salmonella的抗菌效果。

Lipopolysaccharides, fromProteus vulgaris是普通变形杆菌 (Proteus vulgaris) 提取的脂多糖内毒素和TLR-4激活剂，属于S型LPS，能够激活免疫系统的致病相关分子模式 (PAMP) 并诱导细胞分泌迁移体。其典型结构由O抗原、核心寡糖和脂质A组成。该化合物具有独特的分子结构及对壳聚糖的优良亲和力 (Kb=2.72 μM)，优于假结核耶尔森菌 (Kb=6.06 μM) 和大肠杆菌 (Kb=79.50 μM)。
