| Description | 9-hydroxy Stearic Acid is a hydroxy fatty acid that is the active metabolite of 9-PAHSA. 9-hydroxy Stearic Acid is formed from 9-PAHSA through carboxyl ester lipase in the liver and pancreas. The 9-hydroxy Stearic Acid (5 μM) was stearic acid, which inhibited the expression of histone deacetylase 1 (HDAC1) in the lysate of HT-29 colon cancer cells. 3. When the concentration was 100 μM.1, the proliferation of HT-29 cells was inhibited and cell cycle arrest was induced in G0/ g1 phase. |
| In vitro | 9-hydroxy Stearic acid is a hydroxy fatty acid and an active metabolite of 9-PAHSA .[1][2] It is formed from 9-PAHSA by liver and pancreatic carboxyl ester lipases.2 9-hydroxy Stearic acid (5 µM) inhibits histone deacetylase 1 (HDAC1) in HT-29 colon cancer cell lysates.[3]It inhibits the proliferation of, and induces cell cycle arrest at the G0/G1 phase in, HT-29 cells when used at a concentration of 100 µM.1.[1] |
