Vitamin A combined with retinoic acid increases retinol uptake and lung retinyl ester formation in a synergistic manner in neonatal rats

Journal of Lipid Research, 2006
Vitamin A (VA) is stored in tissues predominantly as retinyl esters (REs), which provide substrate for the production of bioactive retinoids. Retinoic acid (RA), a principal metabolite, has been shown to induce postnatal lung development.

Synthesis of 4, 4-difluoro analogs of retinol and retinoic acid.

Journal of Lipid Research, 1984
Oxidation of retinol at the C-4 position is a major metabolic route to biologically inactive excretory products. Thus, the replacement of hydrogen with fluorine at C-4 might well modify the rate of metabolism, biological activity, and pharmacological ...
