    Study demonstrated that n-butylidenephthalide (n-BP)functions by regulating the early part of the kynurenine pathway through the downregulation of tryptophan 2, 3-dioxygenase (TDO2), which decreases the downstream neurotoxic product, quinolinic acid (QA). Findings indicate a correlation between n-BP, TDO2, QA, calpain, and toxic fragment formation.
