​At the cellular level, SFA drugs act through several mechanisms, including the activation of G protein-coupled receptors (GPCRs). 

SFA-002 acts as an immunomodulator to maintain immune homeostasis.​

SFA-002 suppresses HDACs to increase Treg differentiation, promoting up-regulation of anti-inflammatory IL-10 and Inhibition of several pro-inflammatory cytokines (IL-17, IL-23, TNF-α, and IFN-y)
