Biological Activity

4-Phenylbutyric acid is an inhibitor of HDAC, inhibits the growth of NSCLC Cell Lines at 2 mM. 4-Phenylbutyric acid is also an inhibitor of endoplasmic reticulum (ER) stress. 4-Phenylbutyric acid (0-5 mM) inhibits ASFV infection in a dose-dependent manner. LPS decreases the level of p62, whereas 4-Phenylbutyric 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 4-Phenylbutyric acid treatment, supporting that 4-Phenylbutyric acid inhibits LPS-induced autophagy.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
