| 体外研究 | Chitosan oligosaccharide (COS) represents a class of natural polymers that holds therapeutic promise in several diseases due to not only its physiochemical properties including water-solubility and low viscosity but also its favorable pharmacological properties including good pharmacokinetics and safety profiles and diverse beneficial biological activities. Activation of AMPK and inhibition of inflammatory signaling pathways including NF-κB and MAPK pathways are recognized as major mechanisms responsible for several effects of Chitosan oligosaccharide (COS) including anti-inflammation, anti-cancer, and anti-diabetes. COS can interrupt cancer progression at multiple stages by modulating several signaling proteins/pathways including NF-κB, AMPK, mTOR, caspase-3, CD147, MMP-2, MMP-9, and VEGF. In vitro experiments have demonstrated that Chitosan oligosaccharide (COS) induced the death of several cancer cell types including ascites, bladder cancer, prostate cancer, lung cancer, liver cancer, leukemia, cervical cancer and colorectal cancer. The values of IC 50 of Chitosan oligosaccharide (COS) in inducing cytotoxicity are 25 μg/mL-50 μg/mL depending on types of cancer cells. |
| 体内研究 | The oral administration of Chitosan oligosaccharide (16 mg/kg/day) suppresses the production of the proinflammatory cytokines involved in allergic reactions, i.e., IL-4, IL-13 and TNF-α, in the lung tissues and bronchoalveolar lavage fluid of the mice. Last, an anti-inflammatory effect of Chitosan oligosaccharide (COS) on lymphocyte activation has been documented in a rat model of autoimmune anterior uveitis induced by immunization with bovine melanin-associated antigen. Chitosan oligosaccharide (COS) inhibits UV-induced macroscopic appearance in mice skin. Compared with healthy dorsal skin with smoothness and some shallow wrinkles of hairless mice in normal control group, UV exposure for 10 weeks triggers skin erythema, dry, thickening, sagging and coarse wrinkles, and even leathery appearance and slight flesh-colored lesion in the model mice, the visual score of which is markedly higher than that of the normal control group (p<0.05), indicating that UV induces photoaging in skin surface. |

壳聚糖低聚乳酸酯 - 简介
壳寡糖是一类由葡萄糖分子组成的多糖化合物。它具有以下性质：
结构稳定：壳寡糖是由多个葡萄糖分子通过特定的连接方式组成，具有较高的结构稳定性。
溶解性：壳寡糖在水中具有较好的溶解性，可以形成透明溶液。
生物活性：壳寡糖具有多种生物活性，包括抗菌、抗病毒、抗氧化、抗肿瘤和免疫调节等作用。
壳寡糖的制备方法：
微生物发酵法：通过采用适当的微生物（如真菌或海洋细菌）利用废弃物或天然聚糖产生壳寡糖。
酶法：利用特定酶催化废弃物或天然聚糖，生成壳寡糖。
化学合成法：通过化学反应合成壳寡糖，该方法成本较高，用途较少。
壳寡糖的安全信息：一般来说，壳寡糖是一种天然产物，较为安全。每种具体的壳寡糖可能存在差异，在使用时需要参考具体产品的说明书，并遵守相关安全操作规范。对于过敏体质的人群，可能会引发过敏反应，应谨慎使用。
