Fenretinide (Synonyms: 4-HPR, 4-Hydroxy(phenyl)retinamide, MK-4016, Retinoic Acid p-hydroxyphenylamide, Ro 22-4667)

Cell lines

T-ALL cell lines, CCRF-CEM leukemia cells, CCRF-CEM and Jurkat cell, OVCAR-5 cell

Preparation method

The solubility of this compound in DMSO is > 19.6 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

>1 μM, 3 days

Applications

Fenretinide inhibited the growth of many tumor cells, including small-cell lung cancer, malignant hemopoietic cells, and breast cancer cells. The IC50 values of Fenretinide were 0.3 and 0.4 μM in 222 and UCI 101 ovarian cancer cell lines. Fenretinide showed antitumor activity in selected T-ALL cell lines. Fenretinide inhibited DES activity in CCRF-CEM leukemia cells in a dose and time dependent manner, leading to a concomitant increase of the endogenous cellular dhCer content. Fenretinide (3 μM) induced dhCer accumulation in both CCRF-CEM and Jurkat cells. Fenretinide (> 1 μM) inhibited OVCAR-5 cell proliferation and viability, with 70-90% growth inhibition at 10 μM. Fenretinide (1 μM) significantly inhibited OVCAR-5 invasion after 3 days preincubation.

Animal models

HFD-fed male C57Bl/6 mice, NOD/SCID mice

Dosage form

Intraperitoneal injection, 10 mg/kg

Application

Fenretinide (10 mg/kg, i.p.) selectively inhibited ceramide accumulation HFD-fed male C57Bl/6 mice. Fenretinide treatment improved glucose tolerance and insulin sensitivity. Addition of 25 mg/kg ketoconazole to Fenretinide in NOD/SCID mice increased 4-HPR plasma levels.

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.
