产品介绍

生物活性

COG 133 is a fragment of Apolipoprotein E (APOE) peptide with potent anti-inflammatory and neuroprotective effects. COG 133 is also a nAChR antagonist with an IC50 of 445 nM. COG 133 (0.02, 0.2, and 2.0 μM) improved cell numbers in glutamine free media. In IEC-6 cells, COG 133 (0.2-20 μM) improved cell migration following 5-FU challenge, reaching the same migration level as controls. COG 133 (3 μM) significantly increased the mitotic crypt numbers in C57BL6J wild-type animals. COG 133 treatment improved crypt architecture and reduced lamina propria inflammation. COG 133 (3 μM) significantly reduced the intestinal MPO levels. COG 133 partially decreased TNF-α level in the proximal small intestine from 5-FU-treated mice. In both wild-type and ApoE knock-out mice, COG 133 (3 μM) reverted the increase in Tunel-positive cells in the proximal intestine induced by 5-FU. COG 133 caused higher expression of the NF-κB in the improved intestinal mucosa.

不同实验动物依据体表面积的等效剂量转换表(数据来源于FDA指南)

小鼠大鼠豚鼠仓鼠
重量 (kg)0.020.151.80.40.0810
体表面积 (m2)0.0070.0250.150.050.020.5
Km系数36128520
动物 A (mg/kg) = 动物 B (mg/kg) × 动物 B的Km系数
动物 A的Km系数

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
