COG 133是载脂蛋白E (APOE)肽片段,具有有效的抗炎和神经保护作用。COG 133也是一种nAChR拮抗剂,IC50为445 nM。COG 133(0.02、0.2和2.0 μM)提高了无谷氨酰胺培养基中的细胞数量。在IEC-6细胞中,COG 133 (0.2-20 μM)改善了5-FU刺激后的细胞迁移,达到与对照组相同的迁移水平。COG 133 (3 μM)显著增加C57BL6J野生型动物的有丝分裂隐窝数量。COG 133治疗改善了隐窝结构,减少了固有层炎症。COG 133 (3 μM)显著降低肠道MPO水平。COG 133部分降低5- fu处理小鼠小肠近端TNF-α水平。在野生型和ApoE敲除小鼠中,COG 133 (3 μM)逆转了5-FU诱导的近端肠中tunel阳性细胞的增加。COG 133使改善后的肠黏膜NF-κB表达升高。
