Description

The abstract shows tefinostat effectively stimulates VLCFA degradation but is less potent than entinostat in macrophage polarization, despite both being HDAC inhibitors. Understanding this mechanistic difference is crucial for optimizing therapeutic selectivity while maintaining efficacy in neuroinflammatory disorders.
