Formula
C97H181N37O19
Purity
99.03%

Solubility

217mg/mL in DMSO

Physical Appearance

A solid

Storage

Store at -20°C

Protocol

Cell experiment [1]:

Cell lines

IEC-6 cell monolayers

Preparation method

Soluble to 1 mg/ml in sterile water. General tips for obtaining a higher concentration: Please warm the tube at 37°C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20°C for several months.

Reacting condition

0.02, 0.2, 2, 5, 10, and 20 µM, 24 h

Applications

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.

Animal experiment [1]:

Animal models

5-fluorouracil (5-FU)-challenged Swiss mice, C57BL6J ApoE knock-out mice

Dosage form

Intraperitoneal injection, 0.3, 1, and 3 µM, twice daily for 4 days

Application

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.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
