Senkyunolide A is a phthalide originally isolated from celery seed essential oil that has cytoprotective and antiproliferative activities. It protects against cell injury induced by corticosterone in PC12 cells in a time-dependent manner when used at concentrations ranging from 0.125 to 0.5 mg/ml and reduces corticosterone-induced apoptosis at a concentration of 0.5 mg/ml. It also reverses increases in protein levels of phosphatase 2A (PP2A) and α-synuclein and reverses decreases in the phosphorylated forms of PP2A and α-synuclein. Senkyunolide A inhibits cell proliferation of HT-29 colon cancer (IC₅₀ = 54.17 μM) but not non-cancerous human CCD-18Co colon cells (IC₅₀ = 109.11 μM).

A slightly yellow oily substance, soluble in organic solvents such as methanol, ethanol, and DMSO, derived from the rhizome of Chuanxiong.

(3S)-3β-Butyl-1,3,4,5-tetrahydroisobenzofuran-1-one has anti-cerebral ischemia and anti-Alzheimer's disease effects, and can inhibit uterine rhythmic contractions.

ChEBI: Senkyunolide is a member of 2-benzofurans.
