| In vivo study | Wild-type mice produce nanomoles of Desaminotyrosine per gram of feces and have picomolar quantities of Desaminotyrosine in the serum. Desaminotyrosine (200 mM) treatment before influenza infection, protects from influenza by type I interferon (IFN) signaling, with no effect on weight loss or survival in mice with or without vancomycin, neomycin, ampicillin, and metronidazole (VNAM). Desaminotyrosine enhances type I IFN in macrophages via type I IFN amplification in mice. |

| Introduction | p-hydroxyphenylpropionic acid is also called phloretin acid. White to light yellow crystals. Insoluble in benzene and chloroform, soluble in ethanol, ether, ethyl acetate and hot water. The adjacent position will show color when it meets ferric chloride, but the opposite position will not show color. It can be used as a raw material for medicine, preparing stomach medicine and as a raw material for pesticides. |
| preparation | ① phenol is used as raw material to react with acrylonitrile to generate p-hydroxypropiononitrile, which is then hydrolyzed to obtain the product; ② using p-hydroxybenzaldehyde as raw material, Perkin reaction with acetic anhydride in the presence of sodium acetate to generate p-hydroxyacrylic acid, which can be prepared by hydrolysis. |
| Biological activity | Desaminotyrosine is a microbial-related metabolite that prevents influenza by expanding the type I interferon signal. |
| Uses | Used as a pharmaceutical intermediate Sensitive fluorescent substrate for horseradish peroxidase and other peroxidase. |
