生物活性

4-Phenylbutyric acid (4-PBA) is an inhibitor of HDAC and endoplasmic reticulum (ER) stress, used in cancer and infection research.

体外研究

4-Phenylbutyric acid (4-PBA) is an inhibitor of HDAC, inhibits the growth of NSCLC Cell Lines at 2 mM. Benzenebutyric acid in combination with ciglitizone results in enhanced growth arrest of cancer cells. 4-Phenylbutyric acid (0-5 mM) inhibits ASFV infection in a dose-dependent manner. Benzenebutyric acid also inhibits the ASFV late protein synthesis and disrupts the virus-induced H3K9/K14 hypoacetylation status. Benzenebutyric acid and enrofloxacin act synergistically to abolish ASFV replication. Addition of bafilomycin A1 results in accumulation of LC3II, whereas 4-Phenylbutyric acid 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 4-Phenylbutyric 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 4-Phenylbutyric 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.

体内研究

LPS induces significant bone loss and decreases bone mineral density (BMD), bone volume (BV/TV), and trabecular thickness (Tb. Th) compared with PBS alone, whereas trabecular space (Tb. Sp.) is increased. 4-Phenylbutyric acid (4-PBA) attenuates LPS-induced bone loss. Treatment with 4-Phenylbutyric acid increases BMD, BV/TV, and Tb. Th. compared with LPS alone, in addition to decreasing the enlargement of Tb. Sp., but no change is observed when mice are treated with Benzenebutyric acid alone. OC.S/BS as assessed by TRAP staining is also significantly reduced when Benzenebutyric acid is administered to LPS-treated mice. However, OC.N/BS tends to decrease, although not with statistical significance, when mice are treated with Benzenebutyric acid and LPS. These results indicate that the effect of Benzenebutyric acid on OC from LPS-treated mice is to reduce its size rather than number. Consistent with these findings, a marker of bone resorption in vivo, serum CTX-1 which is elevated by LPS treatment is decreased when Benzenebutyric acid administered to LPS-injected mice. However, co-treatment with Benzenebutyric acid do not significantly affect the levels of serum ALP and osteocalcin, 2 markers of bone formation in vivo, compared with LPS alone. Benzenebutyric acid also reduces the LPS-induced rise in serum MCP-1, indicating that Benzenebutyric acid decreases systemic inflammation induced by LPS.
