S-allylmercaptocysteine, an organic sulfur compound derived from garlic, possesses anti-inflammatory and anti-oxidative properties beneficial in treating various pulmonary diseases. It exerts its anti-cancer effects through multiple mechanisms, including inducing cancer cell apoptosis via the TGF-β signaling pathway and diminishing NF-κB activity while enhancing Nrf2, thereby achieving anti-inflammatory and anti-oxidative outcomes [1] [2] [3].
