Bioactivity | Sodium 4-phenylbutyrate (4-PBA sodium) is an inhibitor of HDAC and endoplasmic reticulum (ER) stress, used in cancer and infection research[1]. |
Invitro | Sodium 4-phenylbutyrate (Sodium phenylbutyrate) is an inhibitor of HDAC, inhibits the growth of NSCLC Cell Lines at 2 mM. Sodium 4-phenylbutyrate in combination with ciglitizone results in enhanced growth arrest of cancer cells[1]. Sodium 4-phenylbutyrate (Sodium phenylbutyrate; 0-5 mM) inhibits ASFV infection in a dose-dependent manner. Sodium 4-phenylbutyrate also inhibits the ASFV late protein synthesis and disrupts the virus-induced H3K9/K14 hypoacetylation status. Sodium 4-phenylbutyrate and Enrofloxacin act synergistically to abolish ASFV replication[2]. Addition of Bafilomycin A1 results in accumulation of LC3II, whereas Benzenebutyric acid (4-PBA) substantially reduces this accumulation. LPS decreases the level of p62, whereas Benzenebutyric acid reverses this decrease upon LPS stimulation for 48 h. The percentage of cells with LPS-induced AVOs is increased at 48 h, whereas Benzenebutyric acid significantly reduces this percentage. Specifically, the percentage of cells with AVOs decreases from 61.6% to 53.1% upon Benzenebutyric acid treatment, supporting that Benzenebutyric acid inhibits LPS-induced autophagy. As a positive control for autophagy inhibition, bafilomycin A1 is used. The percentage of cells with LPS-induced AVOs is reduced by bafilomycin A1 treatment. The decreased OC area and fusion index observed after Benzenebutyric acid treatment are not observed with knockdown of ATG7. Inhibition of NF-κB using BAY 11-7082 and JSH23 reduce the LC3 II level upon LPS stimulation and completely abolish the inhibitory effect of Benzenebutyric acid on LPS-induced effects[3]. |
